Basement Waterproofing in Niagara
Interior waterproofing solutions that keep Niagara basements dry through spring thaw and heavy rain.
How It Works
Free Crack Inspection
We inspect the crack from inside the basement, check for signs of movement or structural concern, and confirm whether injection is the right repair before anything is booked.
Crack Preparation
The crack is cleaned along its full length, surface ports are set at regular intervals, and the face of the crack is sealed with epoxy paste so the injection material stays inside the wall.
Injection
Epoxy or polyurethane is injected port by port from the bottom up until the crack is filled through the full thickness of the wall, not just at the surface.
Verification & Warranty
We confirm the crack is filled end to end, remove the ports, and walk you through the finished repair. Your injection is backed by a written warranty against leaking.
Frequently Asked Questions
What is interior basement waterproofing?
Interior waterproofing manages water at the inside face of the foundation, using methods like crack injection, membrane systems and drainage to keep the finished space dry. It is done without excavating around the home.
Is interior or exterior waterproofing better?
They solve different problems. Interior repairs like injection are ideal for localized leaks in poured walls and cost far less. Exterior excavation is reserved for widespread wall deterioration or failed exterior drainage. We recommend the least invasive fix that actually solves the problem.
Will waterproofing stop mould in my basement?
Stopping the water entry removes the moisture source that mould needs, which is the essential first step. Existing mould on finishes should still be cleaned or remediated separately once the leak is fixed.
When should I waterproof my basement?
Any time you see recurring dampness, efflorescence, staining or active leaks, and especially before finishing a basement. Repairs done before framing and drywall go in are far cheaper than repairs after.
