To perform formwork from boards having a thickness of 20 to 25 millimeters, special shields are made, the width of which is fifty — one hundred millimeters more than the highest foundation. The shields are fixed in the trench to the stands located in an upright position. To prevent fracture of the shields outward when pouring concrete, the outer walls of the formwork are fixed with soil or special spacers into the walls of the pit. Metal elements are installed on wood stands or fixed to the formwork with ordinary wire. To reduce the consumption of concrete solution, the walls of the formwork are tightly sealed with paper, a crowd or cardboard.
