Trusted Basement Waterproofing in Hamilton
GAMCON delivers professional basement waterproofing solutions to control moisture intrusion, stop water seepage, and prevent basement flooding. Our services are designed for lasting protection and include both interior waterproofing and exterior waterproofing systems, backed by experienced technicians and a home waterproofing warranty.

Exterior Basement Waterproofing
Exterior waterproofing prevents water from penetrating the outside of the foundation. This includes excavation to the footings, drainage system installation, and applying a waterproof membrane, bitumen coating, Delta membrane, and drainage mat. We install a French drain system and perform weeping tile installation to redirect water and relieve hydrostatic pressure.
Interior Basement Waterproofing
Interior waterproofing manages water that enters the basement through foundation cracks or joints. We install vapor barriers, interior drainage channels, and sump pump systems. Sealing materials such as hydraulic cement, polyurethane sealant, and epoxy crack injection are applied to stop leaks and reduce basement dampness and basement humidity control issues.
Crawl Space Waterproofing
Crawl space waterproofing eliminates excess moisture that leads to mould and structural decay. Our service includes sealing with vapor barriers, installing perimeter drainage systems, and applying insulation solutions that support mold prevention and improve indoor air quality.
Foundation Crack Repair Services
We provide permanent basement crack repair using foundation crack injection. Our team applies epoxy crack injection or polyurethane sealant to fill cracks in concrete walls. These methods prevent leaks and maintain the strength of your concrete foundation repair.
Sump Pump Installation and Maintenance
Our sump pump installation includes primary and backup pumps to handle water collected from drainage systems. Routine maintenance ensures reliable performance during storms and protects against basement flooding.
Basement Underpinning and Lowering
Basement underpinning addresses foundation settlement and allows for basement lowering. This increases living space while reinforcing the foundation, preparing it for structural waterproofing and long-term stability.
