Preparation of the bottom of the pit
When erecting any type of foundation, the bottom of the pit must be aligned on the horizon. In the case when there is no level at hand, it can replace it with an ordinary water level. A pillow of sand from 100 to 150 centimeters is poured on the bottom of the pit of the pit, which is watered abundantly with water and then tightly trimmed. To prevent the flooding of the trench, its equipment is carried out with water casting channels. When erecting foundations made of reinforced concrete or concrete (for example, a strip type), the frontier border is determined by the method of installing formwork. Cardboard formwork is used for columns.
