River District Project

Henry Foundation Drilling Inc was awarded this challenging project located in South Vancouver’s River District community. The project consisted of 460 pcs of 900mm diameter secant piles installed to a depth of up to 18m in difficult soil conditions with a water table of only 2m below ground. The pile toes were installed into a clean sand layer that made it difficult to clean the casing without creating a suction and disturbing the bearing stratum. HFDI used an airlift system to finish 330pcs of the 460 piles on the project to get a clean pile bottom and allow those piles to be tremie poured. HFDI used a BG39, BG30 and BG28 for drills and a 100-ton crawler crane for the concrete installation.
