Patching · Toronto & GTA
Concrete Patching
We are a Toronto-based company specialized in repairing concrete slabs, fully restoring their load-carrying capacity. Impressive 1.8 MPa monolithic adhesion allows us to make concrete patches as thin as 5 mm, which saves on costly demolition.

Complete Concrete Restoration
Our specialized materials and application methods allow us to fully repair concrete surfaces, restoring their load-carrying capacity. Concrete slab demolition can usually be avoided, which saves materials, time and labour.
Our industrial-strength materials have been tested to MTO standards to last 25 years, ensuring durable waterproofing.
Why Concrete Surfaces Break
Concrete starts delaminating due to aging and weather conditions. Severe delamination can pose a hazard to resident safety, as is the case with broken-up balcony floors. Cracks also start appearing in wall, ceiling and floor surfaces, allowing water from the environment to enter building structures.
Patching of concrete surfaces must be done in a timely manner to prevent more complex and costly repairs in the future.
Our Patching Solutions
Wall patches: monolithic adhesion allows thin concrete patch repair, and the newly installed patches will not delaminate thanks to an instant, durable adhesive bond. Ceiling patches are done efficiently thanks to 1.8 MPa adhesive strength — even extensive surfaces can be repaired.
Floor / wall corners: leaking through cold joints — the weakest area between adjoining slabs — is eliminated. A lasting adhesive bond keeps the patch in place so new patches will not delaminate, keeping the slab load-carrying capacity intact.
Our Repair Methods
Concrete Patching
Unlike traditional patching that needs two inches of demolition, our monolithic adhesion lets us patch thin and stop cold-joint leaks — shown here as cross-section diagrams.
Traditional Repair Methods
Conventional repairs require a minimum of a two-inch demolition before a concrete patch can be installed. Due to the lack of proper adhesion between new and old concrete, water will continue permeating through cold joints — the weak areas where two concrete slabs meet.
Joint Seal Patching
Patching of concrete slabs is done efficiently thanks to the monolithic adhesion of our industrial-strength materials — saving time, labour and materials. We follow a multi-step procedure: surface cleaning, application of adhesive, patch installation and surface finish.
If the patch must be done on a wet and/or leaking surface, we first dry it with a torch and stop the leak, before following our standard concrete repair procedure.
Cold Joint Removal
To waterproof the area where wall and floor slabs meet, we clean the wall surface and chip out the cold joint up to one inch deep to ensure proper patch installation. If the surface is wet, we stop leaks and dry the area.
An industrial-strength adhesive is applied before the cold joint is covered with specialized cement, forming a 45 degree angle. The patch is then sealed to ensure lasting results.
Common questions
Frequently asked questions
Can you patch a hole in concrete?
Yes. Our materials achieve monolithic adhesion, making the patch stronger than the original slab.
How long will a patch last?
Tested to MTO standards to last 25 years.
How strong is the repaired surface?
Stronger than the original — a lasting 1.8 MPa monolithic bond between new and existing concrete.
Delaminated or broken concrete?
We install patches as thin as 5 mm with 1.8 MPa monolithic adhesion — restoring the slab with minimal demolition and lasting, MTO-rated results.
