Abstract
Pilings are installed for leveling a foundation. A first segment is driven into the ground. Then two support rods of varying length are positioned and grouted into a passage running through the segment. The first support rod is one-half of the height of the piling segment, while the second is one and one-half times the height of the piling segment. An additional piling segment is driven on top of the first segment. Support rods which are twice the height of a single segment are positioned and grouted into the passage. This process is repeated until the assembly is the required depth.
