Basic principles of constructing a concrete floor screed in industrial premises

Building a concrete screed is crucial in industrial environments where robustness and durability are critical. A smooth surface made of well-laid screed can handle heavy machinery and heavy foot traffic. To guarantee that the floor fulfills functional requirements and is long-lasting, the process entails meticulous planning and exact execution.

The subfloor must be properly prepared before the concrete screed is laid. Usually, this entails cleaning the surface to get rid of any impurities or debris that can hinder adhesion. Furthermore, checking the subfloor for any irregularities guarantees a level and smooth screed base.

After preparing the subfloor, the concrete mix needs to be contained by building a formwork or perimeter barrier. This structure keeps the concrete from spreading outside of the specified area and aids in defining the screed’s boundaries. Formwork that has been installed correctly guarantees that the screed will keep its desired thickness and shape.

Industrial floor screeds are made with a concrete mix that is especially designed to be strong and long-lasting. It usually consists of water, aggregates, sand, and cement. For these materials to have the appropriate strength and workability, the proportions are carefully regulated. In order to guarantee consistency and uniformity throughout the batch, mixing is frequently done mechanically.

After mixing, the concrete is poured inside the formwork onto the subfloor that has been ready. To create a level surface, it is then equally spread using instruments like screeds or floats. The concrete is compacted with great care to guarantee maximum density and eliminate air pockets, which adds to the strength of the screed.

For maximum strength and durability, curing is a crucial step after the concrete screed is laid. In order to encourage the cement’s hydration, this procedure entails regulating the temperature and moisture content of the screed. The type of concrete mix and environmental factors can affect the duration of curing.

In industrial settings, well-built and properly cured concrete floor screeds offer a sturdy base that efficiently supports operational activities. They are an essential component of industrial construction projects because they greatly enhance the building’s longevity and structural integrity.

Basic Principles Concrete Floor Screed in Industrial Premises
1. Preparation Ensure the subfloor is clean, dry, and free from debris. Repair any cracks or uneven surfaces.
2. Moisture Barrier Apply a suitable moisture barrier to prevent moisture ingress from the ground.
3. Formwork Install formwork around the perimeter to contain the concrete mix during pouring.
4. Mixing Concrete Prepare the concrete mix according to specifications, ensuring proper proportions of cement, aggregates, and water.
5. Pouring and Leveling Pour the concrete mix evenly within the formwork. Use screeding tools to level and smooth the surface.
6. Curing Allow the screed to cure properly, maintaining optimal moisture and temperature conditions.
7. Finishing Once cured, finish the surface as required, ensuring it meets the desired smoothness and durability.

What buildings are considered industrial??

Industrial spaces are those non-residential building types used for producing, modifying, organizing, or storing new products.

The term "industrial premises" now refers to a much broader range of objects, including internal warm or unheated operational spaces with a span of more than nine meters, a ceiling height of more than four meters, load-bearing truss or beam structures, and a complete frame of vertical and horizontal rod elements of a certain rigidity.

Therefore, items falling into the following categories are included in production facilities:

  • Factories, full -fledged production enterprises.
  • Separate workshops for industrial buildings.
  • Warehouses with various temperature-humid modes.
  • Logistic complexes designed to store various food and non -food products.
  • Sports complexes, covered pools, sites for sports and for the rest of the population.

As per experts, the vast majority of buildings meant for production activities need a concrete flooring screed device. This device not only satisfies the increased operational and constructive requirements, but also fulfills the requirements of the working project, which includes setting up foundations for technological equipment.

Can I make it from concrete?

Concrete floor screeds can always be made in industrial spaces, but there are some subtleties and regulations that apply to the real estate items in that category and the characteristics of the technological processes that are used there.

  • Before installing the screed, a project is developed that involves a static calculation of reinforced concrete structures under the influence of all applied evenly distributed over the area, line, and such point loads.
  • Technical pits, reinforcement zones, and embedded parts for arranging and fastening technological equipment are arranged in the floor screed in industrial premises.
  • All components from which concrete for floor screed is made meet the operational requirements for them.
  • The thickness of the screed is calculated zonally, taking into account extremely loaded areas where production equipment, machines, conveyors are installed.
  • Under dynamic loads in industrial buildings, a floating screed may be required, which requires the installation of a layer of elastomeric material or polystyrene insulation under it.
  • The floor screed in an industrial building can be reinforced with both mesh and rod flat steel frames, according to the calculation results, taking into account all stress isofields and reinforcement zones.
  • A layer of self-leveling floor or another type of finishing coating is placed on top of the concrete screed, which prevents rapid physical wear of the structure, as well as increases its durability, making it easier to care for and clean the floor.

Industrial properties may occasionally need to make cuts to the screed zoning organization. This is required if a furnace, water tank, conveyor, or other equipment is installed at any location that calls for the use of concrete with various properties.

Is this necessary??

The application of concrete floor screed in industrial settings is contingent upon various factors such as temperature and humidity thresholds, in addition to technological constraints. This design is required in standard buildings because she creates a bearing base beneath the last floor. As a result, no major retail center, logistics hub, sports arena, or warehouse could function without a premium concrete screed.

Simultaneously, specific technological requirements are set for certain industrial buildings’ earthen, steel, asphalt concrete, or polymer floors; some of these requirements do not call for the preparation of a cement-sand mortar or concrete screed.

Requirements

Several significant and stringent requirements are presented for concrete floors in industrial buildings based on their intended use, as well as the project’s content and regulatory documentation.

Enterprises

  • Concrete class about compression strength – from B15 – B20 or more.
  • Strength – from 40 MPa or more, with amplifiers in the locations of technological equipment.
  • Thickness – in the absence of significant loads, can be from 70 mm, but the recommended thickness of the concrete layer for industrial buildings starts from 120 – 150 mm.
  • The floor screed in industrial premises must meet the requirements for water resistance and have the appropriate class – from W4 – W. If the tightness is not enough, the designers put a separate waterproofing in the floor pie.
  • Frost resistance of the screed in indoor areas is an optional factor, which is why concrete can have a class of F75 or more.
  • Any other characteristics of concrete for industrial buildings are assigned only depending on the technological processes that occur in it, which requires an individual approach from an engineer when preparing drawings.

Warehouse complexes

  • Minimum permissible concrete class – B20 – B22.5.
  • Strength – from 40 – 50 MPa and above, but in the area of ​​passage of cargo trolleys to ensure logistics, a self-leveling floor made of more durable materials may be required.
  • The thickness of the screed in warehouses is from 100 mm or more. If it is necessary to maintain a fixed temperature, the thickness can be increased due to porous materials acting as insulators.
  • The water resistance of the concrete structure must be from W4 to W
  • Frost resistance depends on the temperature and humidity conditions in the room, but given the constant connection with the street through transport gateways, it is recommended to include a grade of F100 and higher in the project.

Sports complexes and stadiums

  • Concrete class – from B25 – B30 and more.
  • The strength of the screed must be at least 55 MPa, due to constant dynamic loads.
  • The thickness of the layer is from 12 – 150 mm or more, which guarantees such high strength and load-bearing capacity described above.
  • Water resistance – W6 or more.
  • Frost resistance – from F100 and above.
  • Concrete of such a screed is also subject to additional requirements for the absence of toxins – a class no higher than T1. Thus, when purchasing polymer additives, you need to pay attention to their chemical composition and the absence of ingredients hazardous to health.

The aforementioned requirements serve as the foundation for a comprehensive design that specifies how the premises will be constructed and finished. Installers then utilize this design to create a concrete floor. If the requirements are not met, the acceptance committee will not register the property and will issue several directives that must be followed right away.

Regulations

The above-discussed industrial premises’ concrete floor requirements are governed by the following national regulatory documents:

  • SP 71.13330.2017. Insulating and finishing coatings.
  • GOST 13087-2018. Concrete. Methods for determining abrasion.
  • SP 63.13330.2018. Concrete and reinforced concrete structures.
  • GOST 27006-86. Concrete. Squad selection rules.
  • GOST 26633-91. Heavy and fine-grained concrete. Specifications.
  • GOST 31489-2012. Garage equipment. Safety requirements and control methods.
  • SP 29.13330.201.1. Floors.
  • GOST 30459-2008. Additives for concrete and mortars.
  • SP 57.13330.2011. Warehouse buildings.
  • SP 56.13330.2011. Industrial buildings.
  • SP 332.1325800.2017. Athletic facilities.

Every officially registered manufacturer uses these regulatory documents as a reference when developing technical specifications (TU) and formulations for concrete ingredients or ready-mixed floor screeds. Every batch’s prototypes are sent to testing facilities to undergo mechanical testing on specially designed stands.

The manufacturer receives a state certificate of conformance if the tests are successful, at which point you can create a quality passport for each product item. A protocol is then created.

Construction and pie

Depending on the technological processes that take place there, industrial concrete screed can have one of the following number of layers:

  1. For industrial buildings:
  2. Layer-by-layer compacted base soil from a sand-gravel mixture or floor slab, from 200 mm or more.
  3. If necessary – ring drainage with crushed stone backfill for water filtration.
  4. Leveling screed made of cement-sand mortar grade M300, 30 mm.
  5. Waterproofing made of bitumen-based mastic – 5 mm.
  6. 1 – 2 layers of polymer or rolled bitumen waterproofing – from 5 to 10 mm.
  7. Insulation – usually extruded polystyrene foam – 50 – 100 mm.
  8. Vapor barrier membrane to reduce the risk of condensation, 1 mm.
  9. Remote chairs for fitting reinforcement.
  10. Reinforcement of the structure with 1 or more layers of flat steel frames.
  11. If necessary – installation of utility lines, corrugated hoses, pipelines and other network elements, as well as installation of embedded parts in concrete before pouring.
  12. A layer of concrete of the selected strength class and grades of frost resistance, water resistance, 70 – 200 mm.
  13. Self-leveling protective coating, or porcelain tiles, rubber linoleum, liquid glass, 5 – 15 mm
  14. For warehouses, Unlike industrial buildings, the following elements and utilities are also added to the screed:
  15. Tubes for heating or, conversely, cooling the floor, depending on the technological requirements for the microclimate in the room of the category in question.
  16. Trays and ladders for drainage of surface water, if the warehouse is directly connected to the street.
  17. When installing 2 or more layers of insulation, to increase their rigidity and evenly distribute the load from the screed, a sheet of moisture-resistant plasterboard, 12.5 mm, is laid between them.
  18. For sports complexes There are also individual design features of the screed pie.
  19. The floor surface after the screed is installed is covered with soft rubberized material, 15 – 30 mm.
  20. Membrane with a polymer base “Thermoscope”, 5 mm, which fits under the insulation for a floating screed.
  21. Before installing the slab, immediately after compacting the sand-gravel mixture, less than 100 mm of crushed stone with a fraction of up to 40 mm will be required to ensure guaranteed drainage of groundwater.

As the finishers install each of the pie’s layers—which are explained above—they take pictures of the laid material. These photos serve as the basis for later acts of hidden work, which show meticulous adherence to the project’s specifications, legal paperwork, and the appropriate caliber of installation operations.

What kind of concrete is suitable??

For the purpose of making a floor screed in an industrial building, any concrete will not do, and the property owner may not always be able to locate the ingredients on basic construction markets. The following ranges apply to the average indicators of the primary technical properties of concrete, which is used to build floors in industrial buildings:

  • Compressive strength class – from B20 – B30 and more.
  • Tensile strength class – Bt 2.5 – Bt
  • Frost resistance of concrete – from F75 – F125 and above, depending on the requirements for the room.
  • Water resistance of concrete – not less than W4 – W
  • Toxicity group no higher than T1.
  • Cement grade used as the main binder component – ​​no lower than M400.
  • Recommended amount of cement in concrete screeds of this category – from 15% to 25%.
  • Fine aggregate category – quartz quarry sand with a particle fraction of 1 to 3 – 4 mm.
  • Amount of fine aggregate – from 50% to 75%, depending on the required strength of the screed and the presence of crushed stone.
  • Fine aggregate fraction – granite crushed stone – from 10 to 20 mm, which is determined by the thickness of the screed.
  • Amount or mass fraction of crushed stone in the concrete – from 0% to 25% – 30%.
  • If necessary, concrete should contain antifreeze additives, plasticizers, water repellents and modifying components.

It is advised to plan ahead, gather loads, and compute the floor plinth for the weight of machinery and equipment in order to ascertain precisely what qualities of concrete will be needed for floor screed in an industrial building. The obtained indicators are then given to the supplier in the form of a questionnaire, after which he will already have ascertained the type of concrete he can produce and will draft a commercial offer.

Key concepts must be followed when building a concrete floor screed in an industrial setting to guarantee functionality and durability. This article examines the basic procedures and factors that must be taken into account in order to lay a sturdy concrete screed. It places special emphasis on base preparation, mixing methods, and curing times in order to produce a high-grade, long-lasting floor surface that is appropriate for use in industrial settings.

The process of creating a solution

It is advised to work with experts who apply the most sophisticated automated machinery with maximum efficiency to create a screed in an industrial building. After the job is finished, they should offer a long-term guarantee on the outcome.

If this isn’t feasible, the property owner or the private crew hired for the job will need to buy or rent specialized tools as well as necessary and consumable supplies. You must also adhere to every requirement listed in the technological maps provided below for each category of premises.

It should be mentioned that all tools and equipment need to be of the right caliber, properly sharpened, in good operating order, grounded, dust- and dirt-free, and ready for installation.

Step-by-step instructions for creating

In order to independently create a concrete screed on property for a variety of uses, it is advised that you carefully read through all of the detailed step-by-step instructions that follow.

In stock

When making screeds for warehouses, there are a few key considerations that must be made, and each step must be completed in order:

  • The base is prepared – minor repairs are carried out, cleaning and degreasing of the floor slab, or a layer-by-layer compacted mixture of sand and gravel is arranged, compacted to a degree of 0.95 or higher.
  • A laser level is installed in the center of the room, which projects the beam onto the walls.
  • In accordance with this mark, a line is drawn along the entire perimeter of the space being used on the wall using a marker, which will indicate the top of the concreting screed.
  • A leveling screed is placed on top of the soil base to fix the waterproofing, made of cement-sand mortar with a grade of no more than M300.
  • Coating bitumen waterproofing of the floor is installed.
  • 1 or 2 layers of rolled waterproofing are glued on top of the mastic and heated using gas burners. All layers of waterproofing must be laid strictly in one direction, with the material overlapping along the length by at least 50 mm and fusing each layer until the bitumen base spreads.
  • Expanded polystyrene plates are laid out, which are fixed in a lock, after which they are completely glued with polyurethane foam to achieve perfect tightness.
  • Chairs are placed to distance the reinforcement of the concrete screed slab.
  • In accordance with the project, a reinforcing frame made of longitudinal and transverse rods with a periodic profile of different diameters is knitted and fixed.
  • Inside the screed, corrugations with broaches for cable products, as well as pipes that are necessary to ensure the technological process, are laid in advance.
  • Pre-prepared embedded parts are welded in accordance with the technological design of the premises.
  • All the dry ingredients of concrete are poured into the concrete mixer in the required proportion – cement, sand and crushed stone, after which they are mixed until a homogeneous mass is achieved.
  • Water is dosed into the mixer"s receiving hopper in portions, no more than 1 – 3 liters per serving.
  • Upon reaching the required mobility, usually P3, modifying, antifreeze and other components are added to the concrete.
  • The finished concrete begins to prick into the screed until it reaches the level marked with a marker on the wall
  • When the level is reached, the screed is compacted with a deep vibrator, after which it is left for 2-3 hours until it sets.
  • Over the next few days, until the strength reaches at least 70% of the design, concrete pouring and high-quality care will be required so that the material can achieve the required load-bearing capacity.

Different functional zones in warehouses may require different top coatings. For instance, simple ironing with cement milk or testing is sufficient at the rack location, but high-strength, wear-resistant materials made of novel polymers will be needed for transportation or loading and unloading.

Sports complex

The most important part of finishing work for a sports complex is creating the screed because the quality of the final product will depend on how accurately the concrete mixture is mixed and leveled after it is laid. It is required for work that you follow every step in the following step-by-step instruction:

  • The preparation of the base is carried out according to the same scheme as for industrial buildings.
  • When concreting the solution, up to 5% of plasticizers, as well as fiber -fiber for structural reinforcement, is added to the mixture. This is due to the fact that the structure is always subjected to dynamic loads and vibrations that cause its destruction.
  • A damper elastic gasket is also laid under the insulation, providing the effect of a floating screed.
  • Concrete also contains up to 25% cement and fine aggregate in the form of washed river sand with a fine fraction, which is explained by achieving minimum porosity of the reinforced concrete structure.
  • Immediately after gaining strength, during maintenance, the screed plate for the sports complex is treated with penetrating insulation, after which an elastic rubber crumb screed or a polymer elastic self-leveling floor is installed on top of it, which reduces the risk of injury.

As all sports require the use of an absolutely flat floor plane, in the case of a defect resulting from a technological violation, the screed will no longer function as the typical foundation for the finishing coating.

Industrial premises

In industrial settings, the screed serves as the base for conveyors, machines, and technological equipment all at once. As a result, it can have a variable thickness, is only constructed in accordance with specific projects, and must adhere to the following technological map:

  • Preparation, taking measurements, cleaning and marking are carried out according to the same step-by-step instructions as in the cases described above.
  • Under the floor screed slab, if it is installed on the ground, it is recommended to lay drainage from reshaped pipes sprinkled with fine crushed stone.
  • If it is necessary to achieve a strict temperature regime in the room, to eliminate heat loss, 2 layers of polystyrene foam are laid under the screed with a total thickness of each plate of up to 50 mm, with mandatory bandaging of the seams and foaming of the material.
  • To prevent polystyrene from being pressed under the influence of static loads, it is recommended to lay high-density plasterboard sheets coated with epoxy glue between the layers.
  • When reinforcing the screed, it is recommended to additionally lay a backup mesh in the areas of the most loaded areas of the slab.
  • In the case of storing perishable or frozen products in warehouses undergoing finishing, the screed must be created with a slight slope and with the organization of traps connected to the sewer.
  • The remaining nuances when creating a screed in warehouse compasses with polarity are identical to the creation of the same design in industrial buildings.

Depending on the project’s content, which is developed in accordance with technical specifications and is influenced by the building’s intended use, the workshop’s temperature control, and other specific factors, the technology may differ dramatically.

Rules and technology for care after pouring

The meticulous maintenance of the freshly laid screed material is one of the most crucial steps in the installation of concrete floors in industrial buildings. In order to guarantee the anticipated outcome, dependability, and longevity of the upcoming concrete construction, it must be maintained in compliance with the subsequent guidelines:

  • Immediately after pouring, the concrete is left for 2 – 3 hours until the chemical reaction and setting are complete.
  • Next, it is recommended to cover the concrete with heat-insulating mats so that the moisture that evaporates from the liquid composition remains on the surface to continue the reaction with the hydraulic binder.
  • 24 – 36 hours after installation, it is recommended to hose down the concrete with water to reduce the risk of shrinkage cracks.
  • In the case of concreting the screed in the cold season, heating should be organized – a heat gun is placed under the mats, which should work from 5 to 7 days, until 70% of the structure’s strength is reached.
  • If work is carried out at sub-zero temperatures, in addition to reinforcement, utilities and embedded parts, a PNSV cable is also laid into the structure, and its ends are included in the TMO, which ensures constant heating of the concrete from electricity.

The structure will not be able to support the necessary weight if the concrete screed is not properly maintained during the hardening process. This will have an impact on how long it operates without issues. Any dynamic loads or impulse impacts can cause delamination of the upper parts of the surface, which will immediately cause defects to form, even if the concrete has gained at least 70% of its design strength.

Protection and processing

Facility owners frequently resort to additional protection of the slab from mechanical damage and excessive use in order to increase the wear resistance of concrete screed in industrial premises and extend the service life of the entire structure. The following technologies, procedures, and materials are typically used throughout the course of this multi-stage production process:

  • Drooping insulation device with polymer components.
  • Treatment of hardened concrete with liquid glass solution.
  • Device for penetrating and strengthening composition – methyl methacrylate.
  • Treatment of the slab with epoxy resins and hardeners, which ensures the structural bond of the material and significantly increases water resistance and frost resistance.
  • The device of corundum or quartz tops – high -tech substances that are sold in finished liquid form and are applied to the surface of concrete as well as penetrating waterproofing. These substances repeatedly strengthen the screed and do not even require a top finishing coating.
  • Ironing a screed is the most affordable way to strengthen a structure using dry cement or cement laitance, as well as dough, depending on the amount of water added to the substance.
  • All penetrating compounds are applied in several layers over the surface of the concrete screed, cleared of dust, after which they are absorbed into all the pores of the material, gradually enveloping them and increasing the strength of the structure.

Please be aware that the materials on the above list should only be acquired from reliable vendors in reputable factories. Only select goods that have received a lot of favorable feedback from pleased users on unbiased internet forums.

Coverage options

High-strength finish coatings can be applied on top of the black structure of industrial buildings, in addition to the floor screed’s structural reinforcement. The following building and finishing materials are used to create coverage data, depending on the type of object and its intended use:

  • Self-leveling floor based on high-strength cement – applied in liquid form. Automatically leveled and smoothed using a toothed roller.
  • Installation of adhesive or coating waterproofing using high-temperature gas burners to melt bitumen.
  • The device of epoxy, polyurethane or methyl methacrylate compounds, which also level independently, penetrate into the pores, form a continuous and reliable coating of the screed.
  • Installation of polymer film followed by smoothing it with pressure rollers. Fastening is made using a two-component epoxy compound.
  • Installation of coatings from rubber production waste, which are bonded together with the same epoxy resins. The material is diluted in the container, and then apply to the plane of concrete with a roller and rubbed with a grater.
  • Paul coverage in industrial buildings with porcelain tiles on a special tile with grout of the seams.

Any finishing coating with superior performance qualities will double or triple the concrete screed’s longevity. It also lowers the possibility of dust formation from the rough binder material’s increased abrasion and oil stains, which also helps the finish meet sanitary and hygienic standards.

Defects and their causes

Any concrete screed placed in an industrial setting will be exposed to both static and dynamic loads, as well as heavy and aggressive use. This results in the development of several flaws that compromise the structure’s ability to support loads:

  • Shrinkage cracks that appear when freshly laid concrete is not properly maintained.
  • Trishins arising from mechanical damage, physical wear and tear and permanent vibrations, which especially occurs in sports complexes.
  • Potholes, chips, cavities and pits can form both due to insufficient vibration of concrete after laying, and under shock-impulse loads.
  • Concrete stratification – relevant for industrial premises with special temperature regimes, since with a constant change in internal microclimate, there is an increased risk of destroying a crystal lattice.
  • The formation of influxes or hollows on the plane of concrete-due to the rapid loss of moisture during hardness, which is relevant for concreting in the winter, or if the mobility of the concrete mixture is exceeded.

Since their continued development will worsen the situation and hasten the concrete structure’s demise, all of these defects must be found during screed diagnostics and repaired thereafter.

Repair process

Experts advise employing the following techniques to arrange screed repairs, based on the kind of industrial facility and the extent of the concrete slab damage:

  • Sealing defects with repair compounds based on high-strength non-shrinking cement.
  • Local cutting down of the structure with further installation of the same concrete patch.
  • Grinding the concrete surface for minor defects.
  • Milling of concrete screed with a special machine, removing a layer of 10 mm or more.
  • Installation of self-leveling floors or other high-strength coatings with polymer components.
  • Installation of porcelain tiles.
  • Pouring a duplicate concrete screed using the existing old base as the load-bearing part for the new material.

To avoid egregious errors and infractions when doing repairs, it is advised that you acquaint yourself with master classes and video lessons from experienced installers. These professionals frequently distribute these resources to other users on independent Internet forums. This will enable you to pick up a variety of tips and methods while also considering the subtleties that will result in the full restoration of concrete’s performance attributes.

Advantages and disadvantages

Because concrete screed for industrial buildings has so many of the following benefits, it is used everywhere and on most construction sites:

  • High mechanical strength of the structure.
  • Availability of ingredients throughout the country.
  • Possibility of ordering ready-made concrete from the manufacturer from the nearest batching plant.
  • Monolithic continuous construction provides a high level of tightness.
  • Possibility of specifying any thickness and configuration of the screed.
  • Inside the screed you can lay any utility lines, reinforcement cages, as well as embedded parts for fastening technological equipment in the workshop.
  • High adhesion to concrete base.
  • High level of screed maintainability in case of mechanical damage.
  • Possibility of installing any finishing coating on top.
  • A relatively inexpensive building material specifically for floor screeding in industrial premises.
  • Non-flammable and environmentally friendly material based on mineral components.

However, because concrete screeds also have a number of drawbacks, some designers or builders will occasionally turn to alternative technologies when installing floors in industrial buildings:

  • Large number of wet processes.
  • Seasonality of the work, since the water included in the concrete crystallizes at subzero temperatures, which completely stops the chemical reaction and strength gain.
  • The need to provide care over a long period of strength development – up to 28 days, which increases the risk of technology failure.
  • Heavy concrete creates additional loads on floor slabs, which requires their reinforcement.
  • Low wear resistance of concrete, which requires its protection or strengthening from increased abrasion.
  • High risk of getting defective when mixing the concrete mixture yourself.
  • Increased porosity of the material, despite the relatively low price of the screed. In 90% of cases, industrial premises require a finishing layer with polymer additives, which are significantly more expensive.
  • The need to fill the floor in one step, which requires enormous labor costs, especially if we are talking about a large area.

The need for all screed components for industrial buildings in our nation is increasing annually because, despite their drawbacks, these technologies are the most dependable and many users and property owners ignore them.

Cost of work on the device

Since the owners of these establishments frequently utilize concrete screeds for industrial buildings, a variety of contractors provide installation services. Due to intense competition among construction and installation firms, prices for this kind of work have averaged out without sacrificing quality. A device with this design can be ordered for the following retail prices on average in the Russian Federation:

  • Simple concrete screeds with reinforcing a masonry mesh, without preparing the base – from 500 – 600 rubles. for 1 m 2 .
  • Simple screeds with the device of the full floor pie, according to the above instructions – from 1000 – 1100 rubles. for 1 m 2 .
  • Complex ties with embedded parts for industrial equipment – ​​from 1500 – 1700 rubles. for 1 m 2 .
  • Complex structures with embedded parts and utilities – from 1900 – 2200 rubles. for 1 m 2 .
  • Installation of complex coverage with rubberized floors in sports complexes – from 2000 – 2500 rubles. for 1 m 2 .
  • Organization of energy-efficient screeds in warehouses with special temperature and humidity conditions – from 1800 – 2000 rubles. for 1 m 2 .
  • Combined screeds, which have variable thickness, since they simultaneously serve as foundations for technological equipment in production workshops – from 2500 – 3000 rubles. per 1 m 2 .

The location of the facility, the complexity of the design, the existence and quantity of embedded parts, utilities, the amount of work completed, and the contractor’s internal marketing strategy could all have a small impact on the prices listed above.

To guarantee longevity and functionality, careful planning and execution are needed when building a concrete floor screed in an industrial setting. The procedure starts with the base being thoroughly prepared, which entails cleaning the substrate to get rid of any impurities or debris. This is an important step because it guarantees good adhesion and guards against problems down the road like cracking or delamination.

Applying a bonding agent or primer is the next step after the substrate is clean and dry. This promotes a solid and long-lasting adhesion by strengthening the bond between the base and the concrete screed. To get the best results, bonding agent application instructions from the manufacturer must be followed.

It’s important to use precise amounts of cement, sand, and water when mixing the concrete screed. For the entire floor surface to have the same thickness and strength, the mixture must be homogeneous and consistent. A homogenous blend is necessary for a high-quality screed, and it can be achieved with the aid of proper mixing techniques, such as the use of mechanical mixers.

When applying, the screed should be spread uniformly with the right tools, such as floats or straight edges. Through this procedure, any unevenness or dips that might impair the usability of the floor are removed, ensuring that the screed is smooth and level. A flat and even surface requires careful monitoring of the thickness and leveling throughout the application process.

Finally, it’s critical to give adequate curing time after applying and leveling the concrete screed. Concrete can reach its maximum strength and durability with the aid of curing. The right curing techniques, like applying curing compounds or keeping the area damp, should be used based on the particular needs of the project and the surrounding circumstances.

In summary, the process of building a concrete floor screed in an industrial setting entails a series of methodical steps, ranging from preparation to curing. To create a floor surface that is both functional and long-lasting, suitable for industrial settings, meticulous attention to detail is essential during the substrate preparation, bonding, mixing, application, and curing processes.
