Gatineau Concrete specifies Ardex when a slab must land perfectly flat or when an overlay needs to bond seamlessly to existing concrete. We install the full Ardex system, primer, body, topcoat, to the published spec, which means the warranty is real and the floor performs as tested. Call for a free written estimate.
How Ardex Concrete Systems Solve Real Slab Problems
A slab that's out of plane, cracked, or spalled will telegraph through any decorative finish. Ardex solves this by starting with the substrate. Self-leveling underlayments (K-15, K-60) flow across an uneven slab and cure to a flat, stable base that accepts any topcoat without showing the flaws below.
For slabs that are tired but structurally sound, thin overlays (Feather Finish, SD-M, WJ-50) bond to the prepared surface and create a new, seamless finish layer. Repair mortars patch spalls and voids before the system goes down, so the slab is whole before the finish is applied.
We evaluate the slab condition, moisture profile, and the finish that will go on top, then select the right Ardex product line and lock the install sequence.
Prepare the substrate
The concrete is mechanically profiled to the Ardex spec, moisture tested, and primed with the manufacturer's primer system, not a substitute or shortcut.
Apply the system
Primer, body coat or self-leveler, and topcoat or waterproofing layer are installed in sequence at the temperature and timing the Ardex spec requires.
Cure and document
Each layer cures to the Ardex schedule before the next is applied. You receive product data sheets and the install record so the warranty is enforceable.
Trained and certified
What Ardex Certified Installer Status Means
An Ardex Certified Installer has been trained on the product system, knows the failure modes, and installs to the full manufacturer warranty. For you, that means the work is done the way Ardex tested it, with no shortcuts on prep, primer, or topcoat.
Which Ardex line for which job, install spec, certification and what it means for warranty in Gatineau.
Because the slab below the finish decides how the finish ages. Ardex K-15 and K-60 pour a flat, sound surface that takes a finish without telegraphing the slab below, which is exactly what a high-end floor needs.
Yes. Ardex Feather Finish, SD-M and WJ-50 overlays are designed to bond to prepared existing concrete and lay a thin, seamless surface over it, so a tired slab gets a new finished surface without a full tear-out.
Yes. Ardex Certified Installer status means we install to the full manufacturer system, primer through topcoat, so the product warranty is intact and the install does what Ardex says it will.
Ardex waterproofing is designed for below-grade and wet-room applications. We pair it with proper drainage and substrate prep so the system actually keeps water out, not just claims to.
It depends on the slab, the product line and the area. Ardex products carry a premium over generic alternatives because of their performance and warranty; we put the full system cost in a written, itemised quote after seeing the slab.

What Gatineau Clients Say About Their Ardex Installs
Ardex self-leveler before our luxury vinyl plank. The floor came out perfectly flat, no lippage anywhere, and the finished install looks as good as the showroom.

Used Ardex overlay over a beat-up basement slab. New seamless surface, bonded properly, took the topcoat with no surprises. Worth the premium.

They are a certified Ardex installer so the warranty is real. Install was by the book, with the product sheets handed over at the end.

Ardex repair mortar saved us from a full slab replacement. They explained why it was the right call and the patched area has held up fine.
