Below-Grade Waterproofing Supplier – Vancouver

Metro Vancouver’s high water tables, deep excavations and tight lot lines make below-grade waterproofing one of the most important parts of the job. At BC Building Products we supply foundation waterproofing and damproofing systems to below-grade and waterproofing contractors, foundation trades, builders and developers, from single-family homes up to commercial high-rise parkades.

From our Surrey warehouse we supply blindside (pre-applied) membranes for shoring walls, peel-and-stick and fluid-applied membranes for accessible walls, spray-applied damproofing for residential foundations, and crystalline waterproofing for concrete. We stock brands including Tremco, W.R. Meadows, Sika, Siplast, EPRO, Kryton, Soprema, IKO and Naturaseal.

Blindside and pre-applied systems

On zero-lot-line sites, the membrane goes against the shoring before the concrete is poured. We supply W.R. Meadows PRECON, SikaProof A, EPRO PreTak, Siplast TeraPROOF Pre-Applied V-SBS (vertical walls) and H-SBS (under slabs) SBS-modified bitumen membranes, the EPRO e.protect, e.protect plus and e.proformance shoring systems, and Tremco TREMproof 260, a fluid-applied waterproofing for blindside and two-sided walls on commercial high-rises.

Post-applied membranes for foundation walls

Where you can reach the outside face of the wall, choose from peel-and-stick membranes such as W.R. Meadows HydraStop SA and Soprema Colphene 3000, the fluid-applied EPRO e.spray, or Tremco Watchdog H3, a spray-applied foundation waterproofing membrane suited to new homes in BC.

Residential damproofing

For residential foundations we carry Tremco MULSEAL, a water-based spray-applied damproofing membrane, along with Naturaseal DampSeal-SGDP-500.

Crystalline and concrete waterproofing

Kryton Krystol T1 is a surface-applied crystalline slurry for new or existing concrete. We also stock Krystol Waterstop Treatment, Waterstop Grout and Repair Grout, Krystol Plug, and KOSTER and SikaSwell products for joints and leaks.

Complete the system

Waterproofing works best with drainage and protection. Pair your membrane with a drainage board from our Drainage Board range, and ask us about the compatible primers, mastics and terminations.
