Exterior Basement Waterproofing in Toronto
Protect Your Foundation from the Outside In
Water around your home’s foundation is one of the biggest threats to your basement. At UPR, we provide trusted, long-lasting exterior waterproofing services across Toronto and the GTA — stopping leaks before they get inside.
Whether your basement walls are seeping, cracking, or already leaking, we use proven materials and techniques to keep your home dry and protected.
Why Exterior Waterproofing?
Exterior waterproofing is the most effective way to protect your basement. It involves excavating around the foundation, repairing cracks, and applying waterproof barriers that stop water at the source — before it enters your home.
Ideal for:
Homes with repeated basement leaks
Cracked foundation walls
Poor grading or drainage around the house
Preventative protection during renovations or additions

A layer of clear plastic sheet is installed over the Aquabloc for extra protection.- Waterproof Membrane Application
High-grade rubberized or dimpled membrane is applied to block moisture permanently and relieve soil pressure from the wall. Weeping Tile & Filter Cloth Installation
A new perforated drainage pipe (weeping tile) is placed at the footing and wrapped in filter cloth to carry groundwater safely away.Gravel Backfill & Surface Grading
