Interior Basement Waterproofing in Welland, ON

What Is Interior Basement Waterproofing?

Interior basement waterproofing installs an unseen drainage network beneath your concrete slab to capture groundwater before it can damage walls or floors. Rather than digging around your foundation, we cut a slim trench along the perimeter, add weeping tile, seal wall leaks, and tie everything into a sump pit. As hydrostatic pressure builds, water flows into the tile, collects in the sump basin, and is pumped safely away—ensuring a dry, usable basement, even in Welland’s soggiest conditions.
