Engineered Walkdown Basement Entries
Poured concrete stairwells, foundation diamond-cutting, exterior drainage membrane, and heavy-duty sump pump back-ups designed for complete water ingress defense.
Zero Water Ingress. Built for Extreme Rain & Snow Melt.
The biggest risk with below-grade basement entrances is water accumulation. Dhillon Excavation & Concrete designs every walkdown stairwell with a multi-stage drainage defense system that routes subterranean water and surface rainfall away from your foundation.
