First you need to mark the marking, which repeats the location of the supporting external and internal walls of the house. Then proceed to digging trenches. If the work is carried out on a stable soil with a deep occurrence of groundwater, there is enough depth of 50-70 cm. But sometimes there are few and 150 cm if the conditions are unfavorable.
The so -called drainage pillow is laid on the bottom of the trench. It consists of two layers – crushed stone and sand (in total their thickness should be about 15 cm). Then prepare the “base”: pour the drainage pillow with concrete so that its layer is about 10 cm. Next, you need to wait until it grabs.
Then a reinforcing cage is placed in the trench and it is poured with concrete until its level rises to the very top. Install the formwork from the boards and continue to pour concrete for another 20 cm. You will get a foundation that will evenly redistribute the load from the building.
