Interior basement waterproofing captures and redirects groundwater beneath your concrete slab before it can damage walls or flooring. Instead of costly exterior excavation, we cut a narrow trench around your basement perimeter, install a perforated weeping tile (also known as a perimeter drain), seal wall cracks, and tie everything into a sump pit. When groundwater accumulates, it flows into the weeping tile, travels to the sump basin, and is safely pumped away—keeping your basement dry, even during Niagara Falls’s heaviest rains.
