Basement waterproofing in Caledonia.
Heavy rain has flooded Caledonia basements more than once. We find where water gets into yours, from cracks to failed weeping tile, and stop it, backed by the No Leak Guarantee.

Clay ground and a river through town.
The Grand River runs right through Caledonia, and low-lying streets near it, like Forfar Street, still see high water in spring. For most homes, though, the bigger risk is rain. On July 29, 2023, heavy rainfall flooded basements and roads across Haldimand County, and Caledonia was hit hard.
The soil doesn't help. Much of the area sits on the Haldimand Clay Plain, where clay-rich soils drain poorly in places, so water can sit against a foundation long after a storm has passed. That's when cracks start to leak, window wells fill and an undersized sump falls behind.
Waterproofing often needs a permit here. Haldimand County lists adding drainage, dampproofing or waterproofing to a foundation, and adding a backwater valve, as work that requires a building permit, so we plan for it from the first visit.
