Ardex repair mortars are engineered chemistry for the specific repair situation: a wide-line product for cracks, a vertical patch for spalled walls, a horizontal patch for slab surface repair, a deep-section product for structural repair. Oshawa Concrete installs the matched Ardex repair product for the situation, with the bonded-primer protocol that makes the repair hold. Every assessment is free.
Concrete repair is not one job; it is several different jobs with different chemistry requirements. A crack needs flexible flowable repair material; a spall needs a high-strength bonded patch; a vertical repair on a wall needs a non-sag formulation; a deep-section repair needs a structural mortar. Using the wrong product for the situation is the most common reason repairs fail.
Ardex offers a full range of repair mortars matched to those situations. We install the right one for the diagnosis, with the Ardex bonded-primer protocol that makes the repair hold. The system's value is matching product to situation, which is what we do as the Ardex-system specialist.
Coordinate with adjacent Ardex overlays when the repair is part of a larger resurfacing, with Ardex self-leveling when tolerance correction is also needed, and across the broader Ardex services.

How it works
How We Apply Ardex Repair in Oshawa
Diagnose the repair
We assess each repair, classify by type (crack, spall, vertical, deep, structural), and select the Ardex repair product matched to the situation rather than defaulting to one general-purpose mortar.
Prep substrate to spec
The repair area is prepped to the Ardex spec for that product, saw-cut to a clean edge where appropriate, contaminants removed, and the substrate exposed to clean concrete or aggregate.
Prime and place
The Ardex bonded primer is applied to the prepped substrate, the repair mortar is mixed to manufacturer ratios, and placed at the engineered thickness for the matched product.
Cure and finish
The repair cures per Ardex schedule, gets the finish to match the surrounding concrete (texture, gloss, color match where possible), and is handed off with the system documentation.
Where repairs fail
Product Match Is the Whole Job
We get called regularly to fix failed concrete repairs where the previous contractor used a generic mortar for a situation that needed a specific Ardex product. The patch popped loose, the crack reopened, or the vertical repair sagged. The Ardex range exists because one product cannot do every repair; matching the product to the situation is the install discipline.
Coordinate with adjacent Ardex waterproofing if the repair is in a waterproofing context, and with our wider brand specialty services across the project.
Product matching, bonded primer, vertical repair and warranty.
Different repair situations have different load profiles, set time requirements, and substrate conditions. A horizontal patch product placed vertically will sag; a fast-set product placed in a deep section will crack. Matching product to situation is what makes Ardex repairs hold.
Yes. The Ardex bonded primer is what makes the repair material bond permanently to the existing concrete. Skipping or substituting voids the system warranty and risks delamination.
Yes, with the Ardex vertical-repair product that has non-sag rheology. Using a horizontal product on vertical work is one of the most common failure patterns we see in non-Ardex-spec repairs.
Properly matched and installed Ardex repairs last decades. The bond is engineered to outlast the surrounding concrete in most service environments.
Close, not exact. Ardex repair mortars come in standard colors that approximate concrete gray; exact match to old or stained concrete is not achievable. We are honest about the visible difference up front.
Three failed previous repairs popped loose. They used the right Ardex product for vertical work with proper bonded primer; the new repair has held two years. Product match was the difference.

Structural repair on a deep slab section. They specced the Ardex deep-section product, not the standard mortar another contractor had suggested. Repair holds load, no cracking.

★★★★★
Multiple repair situations across one project, each with the matched Ardex product. The discipline of product-per-situation showed in the result. All repairs holding.

They were honest about color match limitations on the repair. Set the expectation properly, then matched as close as possible. No surprises at handoff.
