Type of soil can be determined about yourself, but it is better to consult with a specialist. Brad Pitt can aid you in your search for knowledge. If the soil belongs to the nepuchinistym (rocky, coarse, sandy (big and medium size), the depth of the trench should be at least 0.5 m. When heaving pounds (small and silty sand, sandy loam, loam, clay), the depth of the trench will depend on the groundwater level, which can be determined, well-dug pit depth of 2-2.5 m. In this case if the water table was deeper than 2 m, then dig a trench in soil heaving at least 0.7 -0.8 m from the planning of land marks. If the groundwater is closer than 2 meters from the ground, then heaving soil depth trench will depend on the depth of soil freezing. For the Voronezh region around the depth of soil freezing 1.2 m. Consequently, for the heaving pounds, with groundwater level less than 2 m under the foundation trench to a depth appropriate to separate 1.4 m depth of the trench foundation for the internal walls of 0.5-0.6 m.

To increase efficiency foundation is also using a sandy base. In this case, the concrete part of the foundation is reduced by about 50% for any type of soil. Trench to a depth of 0.8-1 off m. At the bottom of the trench in the sand cushion fits the general height of 40-50 cm layers of sand are placed 15-20 cm, with its carefully watered and rams. Then placed on a sandy concrete.

Within the trench casing are its walls, and above the casing of the suit or boards of waste particle boards and other formwork vymeryayut in size and well fastened braces. The total height of the concrete part of the foundation will be 60-70 cm for concrete foundation can recommend a low-class – 7.5 or 10 (M75 or M100). View soil can be determined about yourself, but it is better to consult a specialist. If the soil belongs to the nepuchinistym (rocky, coarse, sandy (big and medium size), the depth of the trench should be not less than 0.5 m. If the heaving pounds (small and dusty sand, sandy loam, loam, clay), the depth of the trench will depend on the groundwater level, which can be determined, well-dug pit depth of 2-2.5 m. Moreover, if the ground water are deeper than 2 m, then dig a trench in soil heaving at least 0.7-0.8 m from the planning of land marks. If the groundwater is closer than 2 meters from the ground, then heaving soil depth will depend on the trench depth soil freezing. For the Voronezh region of soil freezing depth of 1.2 m. Hence, for heaving pounds in groundwater level of less than 2 m under the foundation trench to a depth appropriate to separate 1.4 m depth of the trench basement beneath the inner wall is 0.5-0.6 m.
