Abstract
Several underpinning arrangements are described. In each, a concrete pile is cast in a hole formed adjacent to the structure to be underpinned. The hole is formed from at or near ground level and is vertical or at an angle close to the vertical. At least one supporting limb is also formed. This extends from the pile hole and engages the structure. When the pile is cast in the pile hole, the pile and supporting limb are made to form a unitary element so that forces exerted on the supporting limb by the structures are transmitted to and borne by the pile. Various configurations of supporting limb are described, as are various arrangements for ensuring that the supporting limb is retained in a position in which it supports the structure. A drilling assembly for use in the method is also described.
