Trusted Basement Waterproofing in Oakville
GAMCON provides licensed and insured basement waterproofing services for homeowners in Oakville. We use proven methods to prevent water seepage, control basement humidity, and ensure long-term waterproofing solutions. Our services comply with Ontario building codes and address everything from minor leaks to full-scale foundation settlement.

Exterior Basement Waterproofing
Exterior waterproofing stops water before it enters your home. Our team excavates the perimeter of the foundation, applies a waterproof membrane, and installs a Delta membrane and drainage mat. We also include French drain system installation and bitumen coating to handle hydrostatic pressure and keep your basement dry.
Interior Basement Waterproofing
Interior waterproofing systems redirect moisture from inside your basement. This process includes the installation of weeping tile systems, vapor barriers, drainage matting, and sump pumps. It’s effective for managing basement dampness, moisture intrusion, and musty basement smells.
Crawl Space Waterproofing
Our crawl space waterproofing services address excessive humidity, mold, and water seepage. We install a durable vapor barrier, hydraulic cement to seal joints, and optional sump pump systems to ensure healthy air quality and protect against water damage.
Foundation Crack Repair Services
We repair cracks using epoxy crack injection and polyurethane sealant. Our foundation crack injection techniques restore structural integrity and prevent water intrusion. These services are essential for both concrete foundation repair and long-term basement leak repair.
Sump Pump Installation and Maintenance
We provide professional sump pump installation, including battery backup systems. Routine maintenance ensures the system operates during storms or power outages. This is vital for effective water damage repair and basement flooding solutions.
Basement Underpinning and Lowering
Basement underpinning and lowering services increase ceiling height while stabilizing your home’s structure. We reinforce the existing foundation and improve moisture control. This process is especially useful in older Oakville homes experiencing foundation settlement or needing expanded living space.

Why Waterproof Your Basement in Oakville
Oakville experiences heavy rain and fluctuating groundwater levels, making it essential to protect your foundation. Waterproofing reduces the risk of mold growth, water damage, and structural decay.
