How much does it cost to fill in formwork - prices for pouring formwork

Any person who had to build, when building a foundation, faced with a question concerning its strength, sufficient for the future home. In some cases, a strongly powerful foundation is not needed, but for reinsurance it is still made, which leads to additional costs. Under each building is the foundation with a sufficient margin of safety. It can be calculated, and then with respect to costs it becomes clear how much it costs to fill in the formwork, which will serve the entire period of operation of the house.

The most common strip foundation, and if the area of ​​the future house is already known, then you can more or less accurately calculate the cost of its manufacture.

Trench for the foundation with the excavator

In the event that the excavator does this work, then calculate the cost work performed with it, in the range of 250-500 p. per m³, thus, the calculation of the cost per linear meter depends on the depth of the trench and the hired equipment. If the work will be done independently, then you need to:

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

Cost of materials

Cost of construction materials

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

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

Calculation of the required amount of materials

Required amount of sand

Required take into account that only large sand is needed, and the foundation cushion should be 20-25 centimeters thick. To calculate the volume, you need to multiply the length, width and height together. But, at the beginning, all data must be converted to one standard, in this case to meters. If the trench width is 0.3 m and the filling height is 0.25 m, then one running meter will take 0.075 m³ of sand (0.25 * 0.3 * 1). If, for example, your house is 7 * 10 m, then having calculated the length of the trench (10 + 10 + 7 + 7 = 34 m / p), multiply the obtained amount of sand, which will be spent by 1 p / m (in the example it is 0.075) the total length of the trench (34 m / n), get 2.55 m³, which at the minimum cost of 1970 p. / m³ will be 5023,5 r. Do not forget to add to this amount shipping cost. How much concrete is needed can be calculated on the same principle.

The amount of reinforcement to be purchased can also be calculated. Let's start with the simplest design, calculating the metal consumption by 1 p / m. Four rods are laid in the base of the frame, and every 15 cm with knitting wire, we need to bind jumpers, to 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 for unforeseen expenses and substandard balances. With this data, you can calculate the cost of pouring formwork for the entire structure.

Professional Services

In the event that you decide to hire the services of professionals, you need to find out from them , how much it costs to fill the formwork , considering that in this case it will be necessary to pay not only for the materials, but also for the work. Such information is easy to get by going to the site of such firms. Work is estimated for 1 m² of blind area (not for a cube!) And according to the management of such enterprises, a third of the cost goes to salary and payment for services.

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