EXCAVATION AND SHORING
Southwest Contracting was the first excavation contractor in the Lower Mainland to combine excavation with shoring to serve our clients.
Southwest Contracting was the first excavation contractor in the Lower Mainland to combine excavation with shoring to serve our clients. We employ many different shoring methods from drilling IBO anchors in caving ground, to drilled vertical piles (so anchors can span utilities), to specialty drilling and grouting techniques that maintain an excavation’s integrity.
Because of the dominance of native glacial till throughout the Lower Mainland, our shoring method of choice for many projects is shotcrete shoring, which is often 50 percent more economical than shoring with soldier piles and lagging. In addition, jet grouting, soil mixing or secant walls in combination with tieback anchors have been employed to hold water-bearing ground.
While larger projects such as the Vancouver Convention Center have been noteworthy, smaller projects to install shear walls within existing buildings are becoming commonplace as new codes for seismic upgrading are implemented. Our 20 or so machines cover the full spectrum of services required of any comprehensive Lower Mainland excavation contractor.

From shotcrete shoring, jet grouting and bulk excavation, to underground utility installation, road building, hydraulic drilling for tiebacks, seismic anchors, and micropiles, SWC is synonymous with quality, reliability and innovation.
