Ardex is the premium concrete preparation and finishing line we reach for when an interior floor has to land dead flat or an overlay has to read seamless. Portland Concrete installs Ardex overlays, self-leveling underlayments, repair mortars and waterproofing to the published Ardex system, primer through topcoat, so the work performs the way the product was tested to perform. Every project starts with a free written estimate.
Most decorative concrete and high-end resilient flooring lives or dies on what the slab looks like before the finish goes on. Ardex earns its spot because its self-leveling underlayments (K-15, K-60) pour to a flat, sound surface that takes any topcoat without telegraphing the slab below.
Ardex overlays (Feather Finish, SD-M, WJ-50) extend that with thin, seamless surfacing for resurfacing tired concrete, and Ardex repair mortars patch and rebuild spalled or damaged concrete to a sound base before anything decorative goes down.
We confirm which Ardex line suits the slab, the moisture conditions and the topcoat that will go on, then lock the product list and the install sequence.
Surface prep to spec
The slab is mechanically prepared to the profile the Ardex system requires, moisture tested, and primed with the manufacturer's primer, not a substitute.
Prime, body and topcoat
We install the full Ardex system in sequence, primer, body coat or self-leveler, and the finish or waterproofing layer, at the temperature and timing the spec calls for.
Cure and certify the install
Each layer cures to the Ardex schedule before the next goes on, and you get the product data sheets and the install record so any warranty is intact.
Why an Ardex Certified Installer
What an Ardex Certified Installer Means for You
An Ardex Certified Installer means the installer has been trained on the product line, knows the install sequence and the failure modes, and can install to the full manufacturer warranty.
For you, that means the work is done the way Ardex tested the product to perform, with proper prep, primer and topcoat. The same standards-first installer mindset runs through the brands we install, including Sika, Mapei and the wider brand lineup we use.
Which Ardex line for which job, install spec, certification and what it means for warranty in Portland.
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.
Client reviews
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.
