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.
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.
In addition, cracks 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 use of specialized materials that provide monolithic adhesion allows us to do thin concrete patch repair.
The newly installed patches will not delaminate thanks to
an instant and durable adhesive bond.
Concrete patching is done efficiently on ceiling surfaces thanks to 1.8 MPa adhesive strength provided by our specialized materials. Extensive surfaces can be repaired.
Leaking through cold joints (the weakest area between adjoining slabs of concrete) is eliminated. A lasting adhesive bond will keep the patch in place. New concrete patches
will not delaminate, ensuring that the slab’s load-carrying capacity remains intact.
Impressive 1.8 MPa monolithic adhesion allows us to make thin concrete patches, saving on costly demolition.
Patches as thin as 5 mm are applied to repair any delaminated concrete on ceiling, wall, and floor surfaces.
Concrete Slab Restoration
Ability to do extensive patching allows us to fully restore concrete slabs. Recasting is only done when specified by engineers.
Our specialized industrial-strength materials have been rated to the MTO standards to last 25 years. Precise waterproofing solutions and repairs are provided for any concrete surface.
Joint Seal's Repair Methods
Patching of concrete slabs is done efficiently thanks to
the monolithic adhesion provided by our industrial-strength materials and specialized repair procedures. Time, labour, and materials are saved.
To ensure durable results, we follow a multi-step procedure which includes 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.
Joint Seal's Repair Methods
Cold Joint Removal
To waterproof the area where wall and floor concrete slabs meet (cold joint), we clean the wall surface and chip out
the cold joint, up to one inch deep, to ensure proper patch installation. In case the surface is wet, we stop leaks if needed, and dry the area. An industrial-strength adhesive is applied before the cold joint is covered with specialized cement, forming a 45° angle. The patch is then sealed to ensure
Q - Concrete Patch
Q: Is it possible to patch a hole in concrete?
A: Our specialized materials do permit such repairs because they make monolithic adhesion possible, making patched concrete even stronger than the original slab.
Q - Durable Results
Q: How long will the repair last?
A: Since our materials have been tested to the Ministry of Transportation Ontario standards to last for 25 years, the repair will be durable.
Q - Concrete's Strength
Q: How strong is the repaired surface?
A: It is even stronger than the original thanks to the unique qualities of our materials that provide a long-lasting, 1.8 MPa monolithic repair that ensures a full bond between new and existing concrete.
