Purposes of using damper tape for concrete floor screed, types and average price

When thinking about a concrete floor screed, damper tape fulfills a number of crucial functions. This tape, sometimes referred to as isolation tape or expansion joint tape, is essential for controlling the stresses and movements that the concrete experiences during the curing and settling processes. By offering a flexible barrier that allows for the concrete’s normal expansion and contraction in response to temperature changes and structural loads, it aids in the prevention of cracks.

Damper tapes come in a variety of varieties, each made to fulfill particular demands determined by the specifications of the project. Rubber, foam, and synthetic polymer tapes are examples of common varieties. Rubber tapes provide durability and moisture resistance, while foam tapes are perfect for filling larger gaps because of their excellent compressibility. Strong adhesive qualities and flexibility are frequently combined in synthetic polymer tapes, guaranteeing dependable performance over time.

The kind, quality, and quantity of damper tapes needed for the project will all affect how much they cost when it comes to concrete floor screeds. While high-performance synthetic polymer tapes may cost anywhere from $1 to $3 per linear foot, basic foam or rubber tapes typically cost between $0.50 and $1. It is imperative to select a tape that is appropriate for the particular requirements of your concrete installation in order to guarantee efficient defense against future damage and cracks.

What it is?

This type of roll polymer foam material, known as damper or compensation tape (cord) for concrete floor screed, is placed along a stone structure’s ends or in its expansion joints. This structural component compensates for any temperature changes or other movements within the concrete and stops loads from being transferred to nearby spans or the building frame’s vertical support elements.

What is it for?

When the following result needs to be achieved while the floor covering is in use, a damper tape for floor screeds is utilized:

• Exclusion of load transfer to vertical structures of the building frame.
• Compensation for temperature expansions or compressions of concrete screed.
• Reliable elastic insert in expansion joints of the screed.
• Division of an extended structure into separate cards to eliminate stress concentration and crack formation with minor subsidence.
• Ease of sealing the joint of the screed with the wall structure.
• Possibility of installing a floating floor.
• Increased heat and sound insulation, preventing the transfer of vibration loads and structural noise to adjacent rooms.
• Formation of expansion folds in concrete floor screed.

The damper tape also makes it easier to repair concrete structures because, among other things, partial dismantling does not require cutting out concrete around the entire perimeter of the defect and, when replacing the screed, only one card needs to be removed to preserve the overall performance of the structure, whether it is indoors or outdoors.

Is it possible to do without it??

In the situations indicated below, you can install a concrete screed without using damper tape:

• If the area of ​​the room does not exceed 15 – 20 m2 .
• In the event that the enclosing vertical structures are not connected by monolithic units to all parts of the building frame.
• If the screed is laid in technical rooms, basements, attics, underground spaces, storage rooms, which are not subject to increased requirements for sound insulation.
• If the operation of the floor covering does not imply the transfer of significant forces from external loads.
• If the screed is used in rooms with constant temperature and humidity conditions.
• In situations where a concrete floor screed is installed on top of an absolutely rigid base and elastic membranes or insulating materials are not laid under it.

In other situations, all experts strongly advise installing a damper tape made of foam materials if the screed is installed in a residential building of a private or apartment building, especially if the facility was recently put into operation. This will greatly increase the subfloor structure’s durability and dependability.

Requirements

When it comes to damper tapes, which are available in home retail stores and construction markets across the nation, the following stringent guidelines must be followed:

• Environmentally friendly composition – when heated or during operation, the material of the damper tape should not emit toxins and chemicals that cause allergies in dependent people.
• Elastic deformations – the compressibility of the material must be at least 50%, without the risk of destruction of the foam structure.
• Excellent thermal and sound insulation properties.
• Tensile strength – the material should not collapse when even increased tensile forces are applied.
• Flammability class is no less than G1, that is, the damper tape should not support the spread of open fire.
• Water absorption under pressure is no more than 3% – 5%, which also ensures frost resistance of the material.
• Ease of installation – most modern damper tapes are treated on one side with an adhesive composition, which greatly simplifies gluing the material to walls or other concrete surfaces.
• The width of the damper tape should be no less than the thickness of the screed, but it is recommended to purchase it with a margin of 1 – 2 cm from the nominal height mark, since excess material can always be cut off after the concrete structure has hardened.
• The thickness of the tape should be selected in such a way as to fully compensate for possible movements of the concrete or cement-sand mortar screed during its operation.
• The composition of the damper tape should be such that no ingredient supports the development of bacteria, the formation of mold or other processes of fermentation of the material.

Manufacturers can obtain an official certificate of conformity of the state sample, which guarantees complete safety, reliability, and durability during the material’s operation after it is installed in the seams of the subfloor’s concrete screed, indoors or outdoors, by meeting the aforementioned requirements. This certificate is based on the results of a series of tests.

Advantages and disadvantages

Because these materials have so many indisputable benefits, homemade dumpfer tapes are frequently used to make up for movements or deformation of the concrete floor screed:

• Most often, the physico-mechanical parameters of such products are not lower than that of the damping tapes of the factory manufacturing.
• The possibility of using waste from the main materials for installation work.
• Reducing the costs of acquiring new materials to fill the clearance in the floor of concrete flooring.
• The possibility of choosing such materials, the chemical composition and the main technical characteristics of which are fully consistent with the requirements for a specific room.

However, despite their benefits, these homemade dampers are frequently replaced with other materials or abandoned by the property owner because of their many drawbacks:

• These materials are not certified for use as damper tapes.
• Increased risk of assignment of errors during installation.
• Homemade tapes are rarely equipped with a self -adhesive surface, which requires, using additional adhesive compositions.
• Given that ready -made dampers in rolls are not expensive, a comparison of the cost is required, since cutting other materials can be more expensive for the master or owner of the room.

Homemade dumper ribbons are widely used to install concrete screed and cement-sand mortar in buildings for a variety of uses, as well as on the street, since the majority of drawbacks are subjective.

How to choose the right?

In order to properly select a tape for the compensation laying device between the vertical structures and the concrete floor screed, or to seal the joints in the black flooring, the following functional and structural factors must be considered:

• The thickness and overall dimensions of the product must fully comply with the parameters of the screed being poured.
• It is recommended to purchase damper tapes only with a self-adhesive back side.
• You should buy a tape whose width is 10 – 40 mm greater than the thickness of the screed being poured.
• Each product or batch of it must have a state certificate of conformity, and also be equipped with a quality passport indicating the main technical characteristics.
• When purchasing a tape, it is important to study its thermal and sound insulation properties.
• When you press the tape with force, within a short time it should take on its previous size and shape, without the formation of plastic deformations.
• It is recommended to buy a product that is also equipped with a sanitary and hygienic certificate, which allows it to be used in children"s or medical institutions.
• The price of the product should not be lower than the market price, as this may indicate low quality of the product or the presence of defects.

The product’s brand, the year the business was established, the nation of origin, and the quantity of favourable reviews that pleased customers have left on the brand in question’s products on independent Internet forums are some of the primary selection factors.

Laying rules when pouring

It is not at all necessary to hire professionals to install damper tapes in a structure when installing a concrete screed; all work can be done by hand, provided that you follow a few guidelines and take certain nuances into consideration. Depending on their location within the subfloor structure and their intended use, the technological maps for installing damper tapes in the concrete screed structure are explained in detail below.

On the edge

The following subtleties need to be considered when placing damper tape along the edge of a concrete screed to divide the building’s vertical load-bearing or enclosing elements from the subfloor structure:

• The tape is glued in such a way as to close the entire gap between the screed and the wall.
• The tape should be partially adhered to the subfloor and to the wall structure.
• It is recommended to choose a product whose width is greater than the total thickness of the screed to prevent contact of concrete with load-bearing or enclosing structures.
• After the screed has hardened, the tape should be trimmed along the entire perimeter.
• For better adhesion of the product, it is necessary to first clean the concrete structures from dust, dirt and grease deposits.
• The thickness of the tape is selected in accordance with the calculation of structural noise, the occurrence of which, in turn, is influenced by the functional purpose of the room.
• Cork tape can only be installed in living rooms or offices, where the formation of high humidity is excluded.
• The seam between the wall and the screed must be duplicated on the final coating, since it is also subject to linear deformation due to temperature changes.

The excess polymer tape is cut with a construction knife to the very edge of the plane of the reinforced masonry structure immediately after the concrete screed hardens and gains strength. If necessary, the resulting gap is then sealed with an elastic sealant to keep moisture from penetrating beneath the concrete layer.

For expansion joints inside

When installing an elastic layer, the master will also need to consider several crucial guidelines for sealing expansion joints within the screed:

• The seam between the screed cards must be of constant width.
• The damping membrane must cover the entire thickness of the screed, that is, the height of the seam.
• The seam on top, after installing the damper tape, must be sealed with silicone or acrylic sealant.
• For expansion joints, it is recommended to use only T-shaped or L-shaped tapes.
• It is recommended to concrete the screed cards separately to ensure reliable fixation of the damper tape to the end surface of the concrete screed.
• The thickness of the seam should be 1 – 2 mm less than the dimensions of the damper tape
• If it is necessary to create a seam of increased thickness, it is recommended to install a damper in 2 layers.

It is advised to lay an aluminum or stainless steel profile between sections of stone materials when forming a large-width expansion joint in extended concrete screed structures. This will help form a continuous gap with constant dimensions along the entire length, in addition to the elastic filler from the damper tape.

Bugs and difficulties

Beginners frequently commit a number of egregious errors during the installation process when installing a damper tape in a concrete floor screed. These errors nearly always result in increased material waste as well as other unfavorable outcomes. The most frequent ones are listed below, along with potential solutions for any issues that may have come up, to lessen the likelihood of such errors:

• Choosing low-quality damper tape material – the design will not meet operational requirements.
• Choosing a tape with insufficient width – part of the screed will be closely adjacent to the wall, which will cause non-design forces during its operation.
• The design of direct flying into expansion joints instead of T or L-shaped – the structure will compensate for movements or frost at the end of the expansion only partially, and, as a result, will begin to collapse.
• Installation of the tape in an expansion joint without a metal profile – over time, the edges of the gap will begin to break off, which requires restoration.
• Installation of damper tapes made of cork in wet watering areas – the natural material will quickly begin to rot and be susceptible to the development of mold.
• Joining the damper tape with a gap – sealing of the structure will not be achieved in this place, which causes disturbances during operation.

It is advised that the master or owner of the premises familiarize themselves beforehand with professional master classes and video lessons, which they frequently share with other Internet users in the public domain, revealing various nuances and tricks, in order to completely eliminate all mistakes in the early stages.

Pros and cons of use

A universal structural component, damper tape for concrete floor screed offers the following benefits to the user or property owner:

• Foamed polyethylene or other materials from which the damper tape is made is a certified component that does not emit toxins and harmful substances into the atmosphere, which does not irritate the respiratory tract and does not cause allergies in dependent people.
• This material can be used without restrictions in premises of any purpose, subject to the availability of appropriate design solutions.
• The structure of the synthetic material does not form mold and bacteria do not multiply.
• Foamed polypropylene or polyethylene are practically not subject to plastic deformation, and the structure of the material is completely restored immediately after the load is removed, and therefore these products work ideally as elastic inserts in a concrete screed.
• The tapes are characterized by increased water resistance, and therefore they can partially take on the function of sealing concrete floor screed.
• Low production cost of such tapes, which also affects its availability in retail sales.
• The damper tape does not swell or increase in volume, which is why its effectiveness does not decrease even several years after installation of the screed.
• The damper membrane, regardless of its design and scope of application, provided that there is an adhesive composition on the back side, is quickly installed and does not require the involvement of professionals.
• Modern damper tapes significantly reduce the risk of structural noise propagation on adjacent structures of walls and floors of the building frame, as well as into neighboring rooms.
• The material is not destroyed under the influence of an aggressive environment, including direct ultraviolet rays.
• The damper tape design is reliable and durable.

However, damper tapes also have a limited number of drawbacks, which is why some customers would rather purchase more dependable materials and employ alternative methods to seal seams and gaps in concrete floor screeds:

• Low mechanical strength of the material – the structure of foamed polyethylene is easily damaged even with minor contact with a sharp object.
• When the tape is stretched along its length, it breaks easily.
• Difficulty in joining the material, if necessary. In this case, either gluing of this edge section is required to ensure its sealing, or overlapping of the tape, which leads to a local increase in the thickness of the damper layer.
• All materials made of polypropylene or polyethylene burn well, and when smoke appears, they release caustic substances into the atmosphere.
• Cork damper tapes have an environmentally friendly composition, but at the same time, they can rot.
• The difficulty of installing economy class damper tape, which does not contain an adhesive self-adhesive composition.

It’s crucial to weigh the advantages and disadvantages of each option before purchasing tape so that you can decide on the best course of action for building the subfloor and sealing the seam in the concrete screed.
