Effective drainage systems form the foundation of any successful waterproofing strategy. We install interior perimeter drain systems that capture water before it enters your living space, directing it safely away from your foundation. Our drainage solutions include French drains, channel drains, and footer drains designed to manage groundwater pressure and prevent hydrostatic buildup. Each system is engineered with attention to detail, ensuring proper slope and discharge points that keep your basement dry year-round.

Exterior waterproofing creates a barrier that stops water at its source, preventing moisture from ever reaching your foundation walls. This comprehensive approach involves excavating around your home's perimeter, applying waterproof membranes, and installing protective drainage boards. We also address grading issues and install proper gutter systems to divert water away from your foundation. Exterior waterproofing requires more extensive work, but it provides the most thorough protection available and can extend your foundation's lifespan significantly.

Interior waterproofing offers effective solutions when exterior access isn't feasible or when you need a less invasive approach. Our interior methods include installing vapor barriers, applying waterproof sealants to foundation walls, and creating internal drainage channels. We'll also address wall cracks and floor joints where water commonly enters. This approach works particularly well for homes with finished basements or properties where excavation isn't practical, providing reliable protection without disrupting your landscaping.

A properly installed sump pump serves as your basement's last line of defense against water accumulation. We install primary and battery backup systems that automatically activate when water levels rise, pumping moisture away from your foundation. Our installations include correctly sized basins, reliable pumps with adequate horsepower, and discharge lines positioned to prevent water from returning to your foundation. We'll also recommend maintenance schedules to ensure your system operates flawlessly when you need it most, especially during heavy storms or rapid snowmelt.
