By making a foot on a cast-in-situ pile, for example an auger pile, the load carrying capacity is increased. An inflatable body (18) made of sheet steel folded in a zigzag pattern is placed in the concrete at the bottom of the pile and it is inflated when the concrete has hardened but not hardened so much that it prevents the inflation. The inflation will consolidate the soil around the foot. |
