Piles transfer the load to a lower stratum of greater bearing capacity by way of end bearing or to the intermediate soil through skin friction. Suitable only where the ground conditions are stable and with good load-bearing capacity, strip foundations are fast and cost-effective to build. Since the very first development in masonry and house building in the Neolithic period, foundations have been an essential part of architecture and construction.
