The next factor affecting the quality of the foundation is the type of soil. If you are lucky, and the soil in your area is rocky or sandy, then the “two hundred” concrete is quite suitable for filling the base. However, this type of soil is rather a rarity and most people have to build houses on clay and loamy soils. In this case, the use of low -minor concrete is strictly contraindicated. For such construction, you need to choose stamps not lower than m250. However, it is best to use the composition of the M350 brand — its cost is not much higher, but the indicators of frost resistance and water resistance are higher. In general, frost resistance and water resistance increases directly in proportion to the improvement of the brand.
