Concrete Stair Repair & Restoration
Joint Seal is a Toronto-based company specialising in thin patch applications and concrete restoration. Industrial-strength concrete adhesives let us perform step restoration instead of recasting the stairs — lasting, MTO-rated results.

Concrete Steps Repaired
Concrete steps in disrepair? Not a problem — they can be fully restored thanks to our specialised methods and concrete step repair products that make stair replacement unnecessary.
We waterproof concrete steps by doing extensive crack repair and applying thin patches, which also help restore concrete step geometry. Our specialised industrial-strength materials have been tested to MTO standards to last 25 years.
Why Concrete Steps Break
Concrete step edges are especially prone to wear-and-tear, but any part of concrete stairs can crack, and concrete can start delaminating due to weather conditions.
If the steps are not repaired, they will continue breaking, creating a tripping hazard. Our crack repair, patching and finish coat stop the damage and make lasting concrete step restoration possible.
Application Benefits
Industrial-strength materials and specialised repair methods allow for concrete step resurfacing, making full demolition and recasting unnecessary — stair replacement is only done if specified by engineers.
Thanks to minimal demolition, repairs are done faster and steps are available for use sooner. A thin patch is applied to each step that requires repair, providing a complete, MTO-rated restoration built to last 25 years.
A Waterproofing Finish
Polyurea-based waterproofing membranes are used in a two-layer application: a base coat, broadcast with non-slip aggregates, followed by a top coat that completely seals the stairs.
The result is a concrete surface that is fully waterproofed, safe to walk on and looks renewed — with stairs back in service in less than 24 hours.
Our Repair Methods
Concrete Stair Restoration
We avoid full stair demolition and recasting thanks to our thin patch applications — cracks are repaired, patches installed as thin as 5 mm, and the surface sealed with a non-slip finish.
Surface Preparation
Repairing concrete steps involves a multi-step procedure. Concrete stair repair starts with the removal of any delaminated and unsound concrete so patches bond to a solid substrate.
Crack Repair
To repair a crack on any concrete surface, cracks are cleaned out and then treated with a specialised, industrial-strength adhesive. Patching with polymer cement and a waterproofing primer follow.
Thanks to the monolithic adhesion provided by our products, the repaired surface is fully restored.
Concrete Patching
Under traditional repair methods, concrete steps would have to be fully demolished and recast, which involves more time and materials.
The use of industrial-grade concrete adhesives and polymer cement permits thin patch applications, making the job much more cost-effective and faster while avoiding full stair demolition.
Common questions
Frequently asked questions
My concrete steps are breaking up — do they need full replacement?
No. We restore concrete steps with specialised products — repairing cracks and patching damaged areas.
What protects a concrete stair surface?
A polyurea-based membrane that coats and seals the steps against weather.
Do you replace handrails?
Yes. We coordinate removal of old handrails and installation of new ones.
Cracked or crumbling concrete steps?
We restore concrete stairs with crack repair, thin patching and a non-slip waterproofing finish — no recasting, and back in service in under 24 hours.
