Ardex is the choice when a slab must be dead flat, an overlay must bond seamlessly, or moisture control is non-negotiable. We're an Ardex Certified Installer, which means every job gets the full system: primer, body, topcoat, all to spec. No shortcuts, no substitutes. Call for a free written estimate.
A concrete floor's final look depends entirely on what sits underneath. When a slab is out of plane or has soft spots, Ardex self-leveling underlayments (K-15, K-60) flow to a flat, stable base that any topcoat can land on without showing the slab's flaws.
For tired or damaged concrete, Ardex thin overlays (Feather Finish, SD-M, WJ-50) bond to existing slabs and create a new seamless surface, avoiding the cost and mess of tear-out. Ardex repair compounds patch spalls and rebuild edges before any finish goes down.
We evaluate the slab condition, moisture profile, and intended finish, then lock in the specific Ardex products and the application sequence.
Prepare the substrate
The concrete is mechanically profiled to the spec, moisture-tested, and primed with Ardex primer (never a substitute) to ensure adhesion.
Apply the system layers
Primer, body coat or self-leveler, and topcoat or waterproofing go down in sequence, at the temperatures and cure times Ardex specifies.
Document and hand off
Each layer cures fully before the next. You receive product data sheets and install records so the warranty is valid and traceable.
Certification matters
What Ardex Certified Installer Status Delivers
Being an Ardex Certified Installer means we've trained on the product system, understand the failure modes, and install to the full manufacturer warranty. For you, that's a guarantee the work meets Ardex's own standards.
That same commitment to system integrity runs through every brand we use, from Mapei to Sika to our full product roster. Certification isn't a badge; it's a promise that the install is done right.

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 Portland 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.
