First of all, you need to decide which foundation must be laid: slab or pile. Each of them has its own advantages and its disadvantages. The pile foundation is better for high -speed construction, for small facilities, for moderate latitudes and uneven soils. In all these cases, there is nothing better than a pile foundation on swampy soil: the video in this regard is absolutely unanimous. But for more capital buildings – apartment buildings, roads, urban development – better slab. This type of foundation of roads and slowly in the bookmark requires serious construction equipment, but allows you to build entire cities in the eternal permafrost zone of the Far North, where the swampy soil freezes, then shakes. Having carried out geological surveys, you can find out exactly which type of foundation is better to use. It may be that it will be enough and shallow foundation. This type of foundation is unreliable for serious buildings, but for a frame wooden house or a metal -frame shop, it is exactly what you need. The fine -sized foundation is opposed to the flooding soil due to its own mechanical stiffness: for a small and light structure this is enough.
