Waterproofing Services
Waterproofing plays a critical role in preserving the structural integrity, energy efficiency, and long-term value of any building. Whether it’s a high-rise condo, mid-rise apartment, or commercial property, proper waterproofing safeguards the interior from water intrusion, mold growth, and costly damage while also enhancing comfort and reducing maintenance costs.
Water-related issues are among the most common and costly problems in buildings. Leaks through roofs, foundations, balconies, or underground garages can lead to serious consequences, including structural deterioration, health hazards due to mold and mildew, and energy loss caused by compromised insulation. That’s why it’s vital to address waterproofing proactively before problems arise.

Water Leakage Troubleshooting
Water leaks and moisture issues can stem from a wide range of causes, everything from poor waterproofing workmanship and material degradation to thermal bridging or unexpected structural damage. Our team of waterproofing experts and forensic engineers specialize in diagnosing and resolving complex waterproofing failures in commercial, industrial, and residential buildings. Whether you’re dealing with hidden leaks, recurring dampness, or compromised membranes, we provide thorough assessments to pinpoint the exact source of the problem. We’re here to help.
Interior Waterproofing
Interior basement waterproofing is a vital line of defense when exterior access is limited or when moisture has already made its way inside. GC West Construction can design and install effective interior foundation waterproofing systems that redirect water away from your basement using interior weeping tile, sump pumps, and moisture barriers. This method is ideal for addressing water intrusion through concrete block walls inside, especially in older buildings or finished basements. Our team ensures your interior spaces stay dry, healthy, and protected, no matter the season.
Exterior Waterproofing
Exterior basement waterproofing is the most comprehensive way to prevent water from ever reaching your foundation walls. Our team uses proven methods such as excavation, membrane application, and drainage installation to protect your structure at the source. We specialize in exterior foundation waterproofing for residential, commercial, and multi-unit properties across the Lower Mainland. Whether you’re dealing with cracks in the foundation or moisture penetrating through concrete block walls outside, our exterior solutions are built to last and keep your building safe from long-term water damage.
