General Construction Foundation

Neelu Bachra Centre

Vancouver, BC, Canada

To waterproof and protect the foundation, Xypex Admix C-500 was added to the concrete walls and slab on grade. The walls were shotcrete placed and had a drainage board matting behind them to act as a drainage layer. The walls were placed against the shotcrete soil nailed excavation stabilization layer or against a single sided plywood backing form. The walls were placed in 8 foot lifts with the shotcrete nozzelman commenting that the Xypex mix had no set-delay or other discernible differences in its “shootability” from standard shotcrete mixes.

This building was built into a hillside, with significant water flow into the excavated hole from the surrounding soils. Most leaking cracks in the exterior foundation walls self-healed with only minor repairs in the elevator shaft required. This deep foundation building, built into a known high water flow hillside, was completely and permanently waterproofed using Xypex C-Series admixture.
