Interior Waterproofing

A cost-effective system that controls and redirects water entering through your foundation walls or floor — without exterior excavation.

§ Interior Waterproofing

Interior waterproofing manages water from the inside. Where exterior digging isn't practical or necessary, we install an interior drainage system that collects water at the floor–wall joint and channels it to a sump pump that pumps it safely away.

It's the right call for finished basements, tighter lots, and budgets that need a dependable dry space without a full exterior excavation. Paired with a vapour barrier and proper moisture control, it keeps the space usable and protected year-round.

We assess every basement first — sometimes interior is the smart solution, sometimes it's exterior, and sometimes it's both. You'll get an honest recommendation either way.
