Waterproofing in Coquitlam, BC
Waterproofing experts in Coquitlam, BC. From Burke Mountain to Maillardville, we protect homes and commercial properties from Tri-Cities' heavy rainfall — free estimates.
Why Coquitlam Properties Need Waterproofing
Coquitlam receives over 1,400mm of annual rainfall — significantly more than Vancouver — due to its position at the base of the Coast Mountains. Burke Mountain and the surrounding slopes create significant surface runoff that puts pressure on foundations throughout the city. The older Maillardville neighbourhood has aging housing stock particularly vulnerable to water intrusion, while newer developments on Burke Mountain require proper waterproofing from the start.
Common Waterproofing Issues in Coquitlam
- Basement flooding in Maillardville heritage homes
- Foundation cracks from slope movement on Burke Mountain
- Crawl space moisture throughout older areas
- Retaining wall waterproofing on steep lots
- Strata waterproofing in Westwood Plateau
Building Types We Serve in Coquitlam
Coquitlam's housing ranges from heritage homes in Maillardville to newer single-family homes on Burke Mountain, townhouse complexes in Westwood Plateau, and commercial developments along Lougheed Highway and the Evergreen Line corridor.
Wet Basement Repair in Coquitlam
With 1,400mm of annual rainfall and clay and glacial till on steep slopes, wet basements are one of the most common problems we see in Coquitlam. Moderate flood risk means water is constantly looking for a way in — through wall cracks, floor joints, window wells, and failed weeping tile systems.
Our wet basement repair services in Coquitlam include interior drainage systems, exterior waterproofing membranes, sump pump installation, and crack injection. We don't just patch the symptom — we eliminate the source of water entry so your basement stays dry permanently.
Foundation Crack Repair in Coquitlam
Foundation cracks are widespread in Coquitlam due to clay and glacial till on steep slopes and the constant pressure from 1,400mm of annual rainfall. What starts as a hairline crack can quickly widen as water freezes and expands, turning a small repair into a major structural issue.
Our foundation crack repair services in Coquitlam use polyurethane foam injection for active leaks and epoxy injection for structural bonding. Most repairs are completed from inside your basement in a single day — no excavation, no landscaping disruption, and backed by a written warranty.
