How injection stops water
01
Water sets it off
Polyurethane resin reacts with the water already in the crack. That's why it works on active leaks where patches and sealants wash out.
02
It expands to fill
Foam resin grows many times its liquid size, packing the crack from the inside and blocking even fast-running leaks.
03
Ports hit the crack inside the wall
Ports are drilled at an angle so they meet the crack partway through the concrete. The resin seals the whole path, not just the surface.
04
It stays flexible
Cured polyurethane bends as concrete moves with frost and temperature, so the seal doesn't crack the way rigid fillers can.
05
Leaky manholes cost money
Groundwater leaking into sewers gets pumped and treated like sewage. Sealing manholes and chambers cuts that extra flow.
06
All from the inside
No excavation, no torn-up landscaping or pavement. When we're done, the ports come out and the holes are patched.
What to expect
We look
We come out, find where the water is getting in and give you a clear price.
We inject
We drill small ports and pump in resin that fills the leak path and seals it.
It's dry
We clean up, patch the ports and give you a record of the repair.
Leak repair questions
How much experience do you have?
Over 15 years in the field. Injection is all we do, so the person assessing your leak has seen it before, from hairline cracks to running water in manholes.
Can you fix it while it's still leaking?
Yes, in most cases. The resins we use are made to work on wet, actively leaking concrete.
Do you have to dig outside?
Usually not. We repair from the inside, so there's no excavation.
Will we have to shut down?
Usually not. We can schedule work around your building's normal operations.
Do you do houses?
Yes. We mostly do commercial and municipal work, but we take on residential basements too.
How long does a repair take?
Many single cracks or joints are done in one visit. Bigger jobs, like a whole parkade level, are scheduled in stages around your site.
How long will the repair last?
Done right, it's a long-term fix. The resin stays flexible, so it moves with the concrete instead of breaking loose.
Can you fix structural cracks?
Our injection stops water. It doesn't add strength. If a crack looks structural, we'll tell you and recommend having an engineer look at it first.
What does it cost?
It depends on the number of leaks, access and the type of structure. We'll look at it and give you a clear price before any work starts.
