House Underpinning on Hillside

House backing onto hillside on unstable fill. Foundation was sinking and screw piles were installed up to 20ft deep to find bearing ground. Pile tops will be attached to the foundation to prevent further sinking. Due to the depth of the fill it would have been impossible to excavate to bearing ground and the installation of screw piles was  a fast effective solution without further destabilizing the hillside.Wilsopn 3Wilson 2Wilson 1
