Any person who had to build, with the device foundations faced with a question regarding its strength, enough for a future home. In some cases, very powerful the foundation is not needed, but for reinsurance they still do that leads to additional costs. Under each building is done foundation with a sufficient margin of safety. It can be calculated, and then in terms of costs it will become clear how much it costs formwork, which will serve the entire period of operation of the house.

The most common strip foundation, and if already known the area of ​​the future home, you can more or less accurately calculate the costs on its manufacture.

Trench under the foundation of an excavatorFoundation trench excavator

In the event that the excavator performs this work, then calculate the cost of work performed with its help, in within 250-500 p. per m³, thus calculating the cost linear meter depends on the depth of the trench and hired equipment. If the work will be performed independently, then you need:

  • in the place where the trench will be dug, remove the turf;
  • dig a ditch;
  • install formwork;
  • make a bed of sand (you can use clay, garching, or crushed stone of small fraction) and tamp;
  • for waterproofing, you need to lay geotextiles;
  • pour concrete, sealing it with a vibrator (or stick).

Cost of materials

The cost of building materialsCost building materials

With independent work, you will only need to pay for building materials, namely:

  1. Sand – 1970 rub / m³ (price depends on the quality of sand and place production).
  2. Gravel – 3500 rub./m³.
  3. Concrete B15 – 3500 rub./m³.
  4. Fittings – from 25 rubles per meter; or reinforced mesh 50 × 50 – 100 rub./ m².
  5. Geotextiles – 20 rubles / m².

Calculation of the required amount of materials

Required amount of sandRequired quantity sand

It should be noted that only large sand is needed, and a pillow under the foundation should be 20–25 centimeters thick. To to calculate the volume, you need to multiply the length, width and height between by myself. But first, all the data must be brought to one standard, in in this case to meters. If the width of the trench is 0.3 m and the height of the fill is 0.25 m, then per linear meter it will take 0.075 m³ of sand (0.25 × 0.3 × 1). If, for example, your house is 7 × 10 m, then calculating the length of the trench (10 + 10 + 7 + 7 = 34 m / n), multiply the resulting the amount of sand that is consumed by 1 p / m (in the example, 0.075) for the total length of the trench (34 m / p), get 2.55 m³, which at the minimum cost in 1970 p. / m³ will be 5023.5 p. Do not forget to To this amount add shipping cost. How much concrete is needed can be calculated by the same principle.

The number of fittings to be purchased can also be to calculate. Let’s start with the simplest design, calculating the flow rate metal at 1 p / m. 4 rods are laid in the base of the frame, and every 15 cm with a knitting wire you need to tie jumpers, on which we take another 1 m of reinforcement for each of the seven rows. It turns out 11 meters, but you need to add another meter to the unexpected expenses and substandard balances. Having this data, you can calculate the cost of pouring formwork under the entire structure.

Specialist Services

Services of specialists

In the event that you decide to resort to the services of professionals, then they need to find out how much it costs to fill the formwork, given that in this case it will be necessary to pay not only for materials, but also for work. It’s easy to get such information, by visiting the site of such firms. Work is estimated for 1 m² blind area (not per cube!) and according to the management of such enterprises, one third cost goes to salary and payment for services.

Having such data, you can calculate the cost of filling foundation for your project.
