A failed commercial floor is rarely failed everywhere; most of the system is still working and only specific sections have failed. Gatineau Concrete triages commercial floors zone by zone, diagnoses the root cause of each failure, patches what is patchable, and replaces only what is past saving. The result is a working floor for a fraction of full-replacement cost, with operations continuing around the work. Every assessment is free.
Commercial floor failures come in a few patterns: coating delamination from poor original prep, slab cracking from settlement or thermal cycling, spalling from chemical exposure, joint failure at control joints or expansion joints, or wear-through from heavier traffic than the system was specified for. Each cause has a different repair.
We start with diagnosis, walking the floor zone by zone, identifying what is failing where, what caused each failure, and which failures are isolated versus systemic. Localised failures get repaired in place; systemic failures often mean the original system was wrong and the honest answer is full replacement of the affected zone.
We walk the entire floor with the facility team, mark each failure (delamination, crack, spall, joint, wear-through), photograph and measure each, and classify by cause rather than just by symptom.
Cut and remove failures
Failed sections are cut cleanly with concrete saws, removed without damaging adjacent sound floor, and the substrate is exposed for inspection and the right prep before any repair material goes in.
Prep substrate and patch
Patched sections get the right substrate prep (grind, prime, repair-compatible primer), then the matching repair material is placed, finished to elevation and texture, and bonded to the surrounding sound floor.
Restore finish to match
Where the floor has a polished, epoxy or coating finish, the repaired sections are brought back to match: polished to the same gloss, coated with the same system, or texture-matched as closely as the materials allow.
When repair stops making sense
Repair Has a Sensible Limit
Repair is the right tool when failures are localised, the rest of the floor is sound, and the root cause can be addressed in the repair itself. It is the wrong tool when most of the floor has failed (the original system was the problem) or when the cause cannot be addressed without removing the whole floor.
On every commercial floor assessment we say which case the floor is in. If repair is throwing money at a doomed floor, the quote will recommend full commercial epoxy, polished concrete or another full system as the replacement instead.
Coating failures, slab damage, joint repair and when a floor needs full replacement.
Sometimes patched, sometimes not. If the existing coating is bonded everywhere except the failed zones, those zones can be removed and patched in. If the rest of the coating is also failing (just not visibly yet), patching is a waste of money; we will say so.
We match as closely as the materials allow. Coatings can usually be matched well; polished sections show some line where new pour meets old. The match is part of the project plan up front so the expectation is realistic.
We work around your operations to the extent the materials allow, repairing sections at a time, working off-shifts where needed, and using rapid-cure systems where the floor has to come back in service quickly. The plan is built around your schedule, not against it.
A repair built on a sound substrate with the right bonded primer system lasts as long as the surrounding floor. A repair patched over a failing substrate or with the wrong primer pops loose within a year. Substrate prep is the difference, and we never skip it.
From a single visit for a small patch to several weeks for a multi-zone repair across a large facility. The scope drives the schedule, and the full timeline is in the written quote so you can plan operations around it.
Client reviews
What Gatineau Operations Say About Their Floor Repairs
Coating had failed in three high-traffic zones. They diagnosed the cause as wrong system spec, patched the failed zones with the right system, and we have not seen new failures in two years.

Cracked slab near a loading dock. Diagnosed as thermal cycling, routed, filled with a flexible compound, and the crack has not opened again since. Right diagnosis, right fix.

★★★★★
They were honest that our floor was past repair, the original system was wrong everywhere. Quoted full replacement with the right system. Could have charged for repairs that would fail. Trust earned.

Repaired sections during night shifts so production never stopped. Schedule was tight, they hit every milestone, and the floor came back to full service on time.
