Pile Foundations | Types of Piles | Cassions

Pile foundations are used in the following situations: When there is a layer of weak soil at the surface. This layer cannot support the weight of the building, so the loads of the building have to bypass this layer and be transferred to the layer of stronger soil or rock that is below the weak layer.
