What is the cost of erecting a blind area around the house, what does it include and how is it calculated??

Building a blind area around your home is a crucial first step in preventing water damage to your foundation. Therefore, it’s crucial to comprehend the associated costs before beginning this project. You can effectively budget and prevent unforeseen expenses by being prepared.

A blind area’s (also called a drip edge’s) price is determined by a number of variables. These consist of the labor needed for the installation, the area’s size, and the materials used. You can see the total cost more clearly by dissecting these components.

An enormous portion of the price goes toward materials. Paving stones, asphalt, and concrete are common choices; each has a different price range. The breadth of the blind area and the size of your home will also have an impact on the overall cost because larger spaces call for more labor and materials.

The complexity of the project and local labor rates affect labor costs. For the blind area to be properly constructed and protect your home effectively, professional installation is advised. Nonetheless, planning ahead and possibly cutting costs can be aided by knowing how these costs are broken down.

Building a blind area around your home is a crucial project to safeguard your foundation from water damage, and figuring out how much it will cost requires taking a few different things into account. Materials like gravel, concrete, and waterproofing membranes are included in the overall cost, along with labor costs for installation and excavation. You must determine the width of the blind area, measure the outside of your home, and account for extra features like insulation or decorative finishes in order to precisely estimate the cost. You can plan your budget appropriately and obtain a clear picture of the total cost by dissecting these components.

Factors affecting manufacturing cost

Consider the future structure’s functions as well as building codes and regulations when calculating the cost.

What indicators and standards to consider?

The cost is primarily determined by the building’s surrounding area where the blind area is being constructed. The more material needed for a house’s construction, the larger its perimeter. The breadth of the walkway surrounding the building has an impact on the price as well.

Construction standards SNiP III-10-75, SNiP 3.04.01-87, and SNiP 2.02.01-83 stipulate that the minimum depth for clay soils of types 1 and 2 must be at least 0.7 and 1 meters, respectively.

Soil is classified into two types based on its capacity to contract under its own weight:

1. Slightly sagging (up to 50 mm).
2. Shrinkable.

The length of the roof overhang that extends above the building’s wall determines the blind area’s width as well. For normal soil, the path should always be 200 mm wider; for type 2 soil, it should be 600 mm wider. The blind area’s width is intended to be between 0.8 and 1.2 meters if it is implemented for hydraulic structures rather than residential buildings, and it increases by 1.5 times for karst rocks.

According to SP 82.13330.2016, if the completed structure is intended to be used as a pedestrian element, the paving slab blind area’s thickness should be at least 40–60 mm, taking into account the arrangement of a sand cushion that is 3 cm high and at least 1.5 meters wide.

According to building regulations, the path’s thickness must be:

• for concrete – 70-120 mm,
• reinforced concrete – at least 100 mm,
• and for asphalt concrete – from 50 mm.

The value below ground level is used to calculate the height of the blind area, accounting for the effort required to arrange the gravel-sand cushion.

The coating’s functions determine the blind area’s final width and thickness. Its specifications are designed above average if it has to support the weight of the vehicle. They opt for pressed paving slabs as opposed to regular ones.

Prices for materials and device

Second, the cost of the material is a factor in the structure that will be created:

• asphalt concrete,
• concrete monolithic,
• from paving slabs or paving stones,
• gravel,
• stone,
• made of concrete paving stones.

The amount of materials needed and the expertise of specialists vary depending on the kind of blind area. Some jobs are easier to hire laying workers for, even though the cost could double, because they are more difficult to complete yourself.

In the event that a concrete blind area is to be created, the estimate comprises:

• costs for preparing cement mortar,
• preparation of the base (digging a trench),
• arrangement of sand and gravel cushion,
• installation of a rainwater drainage system and much more.

When it comes to paving slabs, you have to sand the joints and trim the stones. This is an extra cost associated with the arrangement. The owner of the house may desire an insulated structure in certain situations. The estimate will then need to account for the cost of road mesh and insulation.

How to calculate the amount of building materials?

You must determine how much material will be required to build each kind of blind area in order to calculate.

If the length, width, and thickness of the blind area are known, the volume can be calculated regardless of whether the path is made of paving slabs or concrete.

The building’s perimeter on all sides must be multiplied by the path’s width, accounting for the overhang’s size (between 300 and 400 mm), and then multiplied by the building’s height. The easiest way to calculate finished materials is as follows.

Reinforcement is included in the estimate if a concrete blind area is to be used. The amount required is determined by the surface area; typically, concrete is reinforced in two to three rows along its length, with increments of 300 to 400 mm between rows. The guidelines and standards for setting up a blind area are found in SP 82.13330.2016 Territory improvement and SNiP 2.02.01 83.

Concrete pouring, per m2

You must ascertain the quantity of materials required to build one square meter of the completed structure and compute their cost in order to determine the cost:

Concrete	Quantity	Price	Cost per 1 sq.m.
Cement M500	33.5 kg	180 RUR/35 kg	172

Total:	—	—	364

Cushion:

• geotextile 1 sq.m. — 50 rub;
• crushed stone 0.01 cubic.m. — 20 rub;
• sand 0.05 cubic.m. — 30 ​​rub.

Setting up a cushion made of gravel and sand will cost 100 rubles in total.

Reinforcement	Quantity	Price, rub	Cost per 1 sq.m.
Fittings with a diameter of 6 mm	1 linear meter	8	8
Mesh with a diameter of 3 mm with a cell size of 50×50 cm	1 sq.m.	64	64
Reinforcing mesh 3 mm, 150×150 cm	1 sq.m.	24	24
Total:	—	—	96

Boards and spacers for formwork are 50 rubles per meter.

The approximate final cost, excluding specialized services, is 610 rubles for 1 square meter.

How much does it cost to make paving slabs??

You must also compute the amount of material required to arrange tiles that are one meter wide:

Pillow	Quantity	Price	Price
Geotextiles	1 sq.m.	15.9 rubles/sq.m	15.9
Sand	0.15 cubic.m	450 rubles/cubic.m	67.5
Crushed stone with a fraction of 3 mm	0.1 cubic.m.	2000 rubles/cubic.m	200
Clay	0.05 cubic.m.	300 rubles/cubic	15
Total:	—	—	298

In order to apply the final layer, you’ll need:

• cement M500 in the amount of 10 kg – 150 rubles.
• fine sand, 10 kg – 100 rubles.

In total, the finishing layer will cost roughly 250 rubles.

Following this, you must still determine how much the cladding will cost:

Face layer	Quantity	Price	Cost
Wave-shaped paving slabs, size 225×113 mm	—	1430 rubles/sq.m	1430
Curb 1000×80, height 200 mm	2 pcs	265 rubles/running.m	530
Water for watering the blind area	—	40 rubles/cubic.m	40
Total:	—	—	2000

The blind area composed of slabs of paving cost 2550 rubles in total.

The cost of setting up the drainage system with the least expensive asbestos pipes will go up by 185–200 rubles per running meter.

Construction without materials

Labor operations must be included in the arrangement if the cost of construction work must be determined without considering materials.

Regarding a concrete blind spot:

1. Excavation of soil into a dump (all work is carried out manually).
2. Removal of soil off site.
3. Backfilling sand and gravel.
4. Laying geotextiles.
5. For an insulated structure, the laying of penoplex is taken into account.
6. Knitting reinforcement and/or laying mesh.
7. Installation of formwork from boards.
8. Pouring concrete.

There will also need to be a drainage system for water removal if the blind area’s width is greater than one meter. This covers the installation of water intake systems and pipes.

In addition to the usual work of excavating and dumping soil, the following steps are necessary when building a path out of paving slabs:

• laying geotextiles;
• backfilling sand concrete;
• laying paving stones;
• installation of curbs.

The list of construction tasks will also include the installation of a drainage system.

Advantages and disadvantages of choice

Benefits of setting up a turnkey blind area include:

1. Efficiency of work.
2. Compliance with installation technology if a professional company is selected.
3. Estimates, measurements and other calculations are carried out by specialists.
4. If the volume of work is large and the complexity of installation is high, specialists will handle the construction faster and cheaper.

Cons of having a choice:

• high cost of work;
• materials for the blind area are often selected and supplied by the company, which can affect the quality of the finished structure and price.

The most inexpensive and profitable options

Budget-friendly blindings will withstand extended use while also helping to save money.

Among these, they emphasize:

1. Soft (Finnish) blind area. It is made of crushed stone with a layer of 10 cm, sand and waterproofing, it can easily be equipped with your own hands, does not require the help of specialists. The cost of this “Turnkey” design from 1600 rubles in the Moscow region.
2. Concrete blind area on a sand-gravel base. It is made of concrete. The cost ranges from 1300 rubles and above, depending on the region, work prices and materials.
3. Asphalt blind area. Made from asphalt chips on a sandy base. First, quarry sand is poured in a layer of 10-15 cm and crumbs are laid on top, then compacted using a roller. The cost of arrangement is from 270-500 rubles/sq.m.m. The price also depends on the cost of renting special equipment.

It is also advised to keep the path’s width to less than one meter in order to save money, and installing an external drainage system is preferable for added water protection. It will be far less expensive than hidden.

Giving preference to paving stones is preferable if you want to create an eternally blind area. It will last longer even though the cost is higher. You can do the installation yourself to save money. The only drawback is that renting a vibrating machine will cost money.

Rules for drawing up estimates for installation

They use criteria like these to create estimates:

1. SNiP 2.02.01-83 Foundations of buildings and structures. The documents indicate the requirements for the size of the blind area.
2. GOST 9128-97 Asphalt concrete mixtures for road, airfield and asphalt concrete. Regulates the angle of inclination of the asphalt concrete blind area.
3. GOST 7473-94 Concrete mixtures. They regulate the quality of the concrete path, which bears additional traffic loads.
4. SNiP 2.04.02-84 Water supply. External networks and structures. Contains requirements for the arrangement of a clay castle, the angle of inclination for drainage and other indicators.
5. FER. Federal unit prices for construction work carried out by specialists.

Every requirement is reflected in these documents.

When creating an estimate, keep the following in mind:

1. Item contingency. It is advisable to include at least 20% of the total amount here, so that, if necessary, you can continue work without stopping.
2. Costs for delivery of crushed stone, sand, cement and other materials.
3. Costs for containers for mixing concrete mortar, rental of special equipment for soil removal, vibratory placement.

Why is it important to carry out calculations before creating a structure??

Before construction starts, all cost calculations for specialized work and materials must be completed. This will assist you in accurately estimating what workers can navigate:

• how much material needs to be laid as a sand and gravel base;
• existing concrete mixing proportions and their volumes;
• parameters for laying paving stones;
• track angles and other details.

Since the building process needs to be ongoing, a preliminary cost calculation can help prevent unforeseen costs and disruptions to the technology used to lay structural elements.

This section contains a wealth of pertinent and helpful information regarding the blind area’s design.
