DEEP FOUNDATION PILLING
The many available types of piles and associated construction methods are mainly used for foundation load transfer and earth retention systems. They are used in marine – based structures and in land-based structures where the surface soil layers can not provide the required load -bearing capacity. In all situations, piles are utilized to transfer lateral, vertical or a combination of both loads through weak soil layers to a suitable bearing layer. The most common techniques used for deep foundation pile construction are described here.
