Exterior Foundation Waterproofing
Exterior waterproofing starts by excavating the soil around the building’s perimeter to expose the foundation. We apply waterproof membranes, seal cracks, and install drainage systems to direct groundwater away from the structure. Sump Pumps may be added to manage higher water tables and redirect flow safely.
Interior Foundation Waterproofing
Interior waterproofing is used when exterior excavation isn’t feasible. This method includes installing interior drainage channels, vapour barriers, and sump basins. These components work together to relieve hydrostatic pressure and collect water before it can damage the foundation or lead to a wet basement.
Crawl Space Foundation Waterproofing
For homes with crawl spaces, we install sealed vapour barriers and dehumidification systems to control moisture. Drainage systems may also be added to prevent standing water. Crawl space waterproofing helps preserve structural materials and maintain indoor air quality.

Why Choose Foundation Waterproofing
Without proper protection, water can penetrate through cracks in foundation walls, causing leaks, rot, and long-term foundation instability. As water builds around the perimeter, hydrostatic pressure increases and forces moisture into the structure. Waterproofing helps maintain a stable, dry environment and protects against structural damage and future repair costs.
