Test marks at 100mm intervals to facilitate the timing of pile drive speeds. Based on calculated loads of the structure, the piles were tested to 40kN; based on a target drive speed of 100 seconds per 100mm intervals.

A member of staff carfeully records drive speeds. To confirm the reliability of the testing process, a minimum of three successful and consecutive tests were used as a base line.

Subsidence had occurred at the corner of this farmhouse building as a result of a defective drain which had caused leakage to the underside of the foundation. Also, attributable to the buildings movement at this point was the use of inadequate and unconsolidated fill material.
The scheme of repair included the installation of 6no 42mm Shirestabiliser Piles to the corner of the building, the installation of 2no masonry beaming systems, one at low level to distribute the loads equally down to the piles and one at high level to provide additional lateral restraint. Associated works include the provision of intermediate crack stitches and repointing of the chimney stacks, verge detailing and a discrete area on the gable elevation. The works were carried out over a two week period by two men.
