Commercial Waterproofing

Water finds every weak point. We find it first.

A commercial envelope fails at its weak points — cracks in concrete, failed membranes, deck drains, below-grade walls under hydrostatic pressure. Left alone, water becomes structural damage, mould and a warranty headache nobody signed up for.

We waterproof foundations, podium decks, parking structures and below-grade walls to manufacturer spec, and we stop active leaks at the source with crack injection — one of our signature repairs.

What this covers.

The waterproofing and crack repair work that keeps a commercial building dry.
CRACK INJECTION

Crack injection — our signature repair

Epoxy or polyurethane resin injected directly into a concrete crack to stop water at the source, no breaking out the slab.

FOUNDATIONS

Foundation waterproofing

Below-grade walls and footings waterproofed and drained so water never gets a foothold.

PODIUM DECKS

Podium deck & parking waterproofing

Traffic-bearing membrane and coating systems for podium decks, parking structures and plaza decks.

MEMBRANES

Membrane & coating systems

Fluid-applied and sheet membrane systems matched to the substrate and the exposure.

BELOW-GRADE

Below-grade wall systems

Damp-proofing and waterproofing for foundation walls under hydrostatic pressure.

EMERGENCY

24/7 emergency leak response

An active leak doesn't wait for business hours. Neither do we.

Why it matters.

01 / SOURCE
Stop it at the source

Crack injection seals the path water is actually taking, not just the symptom.

02 / STRUCTURE
Protect the structure

Unchecked water corrodes rebar, cracks concrete further and shortens the life of the building.

03 / WARRANTY
Keep the warranty

Installed to manufacturer spec, so your building envelope warranty stays intact.

04 / RESPONSE
24/7 response

An active leak gets triaged immediately, not queued behind a schedule.

Who we build for

Hydro One. School boards. Builders. Property management.

Capital Exterior is run by a tradesman, not a sales team. Our founder started Cover-Tite's metal division, then spent years at Flynn Canada before going out on his own — 15+ years in the building envelope trade.

Common questions

Straight answers, no runaround.

What is crack injection?

A concrete repair method where we inject epoxy or polyurethane resin directly into a crack to stop water at the source, without breaking out the concrete. It's our signature waterproofing repair for foundations, parking structures and podium decks.

Do you offer 24/7 emergency waterproofing?

Yes. Call our 24/7 line for an active leak or urgent waterproofing issue and we'll triage it, day or night.

Can you waterproof parking garages and podium decks?

Yes. Membrane and coating systems for podium decks, parking structures and plaza decks are part of our regular scope, installed to manufacturer spec.

Do you waterproof foundations without full excavation?

Often, yes. Crack injection and interior repair methods can stop many leaks without a full dig, though some conditions call for excavation. We'll tell you straight what your building needs.

What areas do you serve?

Ottawa and the region: Gatineau, Kanata, Orleans, Nepean, Stittsville and out toward Kemptville. If your site is in the NCR, ask us.
