Using industrial-grade epoxy and precision injection techniques, we seal, strengthen, and waterproof your foundation with a full warranty you can rely on.
Protecting Your Home Starts from the Ground Up
A small foundation crack might not look like much — until it lets in water, weakens your walls, and leads to major structural damage. In Toronto, where temperature changes and soil conditions constantly stress concrete, foundation cracks are common. But ignoring them can be costly.
At SDM Contractor, we specialize in foundation crack repair and epoxy crack injection in Toronto, helping homeowners and property managers protect their investments. Whether you’ve noticed water seepage, hairline fractures, or widening cracks in your basement walls, our experts deliver lasting repairs backed by proven materials, advanced methods, and transparent service.
Our work restores both strength and peace of mind, ensuring your foundation stays solid for years to come.
Understanding Foundation Cracks
Not all cracks are created equal. Some are purely cosmetic; others are signs of deeper issues below the surface. Toronto’s clay-heavy soil and freeze-thaw cycles often cause foundations to shift or settle over time, leading to cracks that may:
Allow moisture and water infiltration
Compromise the structural integrity of walls
Create pathways for mold and mildew
Reduce property value and market appeal
Our technicians don’t guess they diagnose. Before recommending epoxy injection or another repair method, we identify the root cause of the problem. That’s what separates SDM Contractor from quick-fix providers. You’ll know exactly what type of crack you’re dealing with, why it happened, and the best way to fix it for good.
Epoxy Crack Injection: The Proven Solution
For most foundation wall cracks, epoxy injection is one of the most reliable and cost-effective repair methods. It works by filling cracks from the inside out using a high-strength epoxy resin that bonds the concrete together — effectively restoring the original structural integrity of the wall.
Our process ensures complete penetration and permanent sealing of the crack, preventing both structural failure and water intrusion.
How Epoxy Injection Works
Inspection and Preparation
We begin by cleaning and preparing the crack surface to ensure the epoxy can fully bond with the concrete. Any loose debris or efflorescence is removed.Port Installation
Injection ports are placed at strategic intervals along the crack to allow the resin to flow completely through its depth.Sealing the Surface
We apply a surface sealer to contain the epoxy during injection, ensuring controlled, even distribution.Epoxy Injection
Under controlled pressure, we inject the epoxy resin into the ports. The material penetrates deep into the crack, bonding both sides of the wall.Curing and Finishing
Once cured, the epoxy creates a waterproof, structural bond stronger than the original concrete itself.
The result? A seamless, watertight repair that prevents leaks and reinforces your foundation for decades.
When Epoxy Isn’t Enough and What We Do Instead
Some cracks are not suitable for epoxy. If the foundation is still actively moving, leaking under pressure, or subject to ongoing stress, polyurethane injection or structural reinforcement may be required instead.
Our team is trained to recognize these cases and recommend the appropriate solution, such as:
Polyurethane Injection for active leaks and flexible movement
Carbon Fiber Reinforcement for horizontal cracks caused by soil pressure
Excavation and Exterior Waterproofing for major structural or drainage problems
We never apply a “one-size-fits-all” solution — because every foundation, soil type, and home condition is unique. SDM Contractor’s approach ensures that you only pay for the right fix, done right.

Frequently Asked Questions
Is epoxy injection permanent?
Yes. When done correctly, epoxy injection restores the concrete’s structural strength and provides a long-lasting waterproof seal.

DIY kits rarely penetrate fully or address the cause of the crack. Professional repairs ensure the damage doesn’t recur and that the work meets code standards.
How much does epoxy crack injection cost in Toronto?
Typical repairs range between $800 and $2,000 per crack, depending on the size, location, and accessibility. We provide upfront quotes so there are no surprises.
Do I need exterior waterproofing, too?
If cracks are caused by external water pressure or drainage issues, we’ll assess whether combining injection with waterproofing gives the best long-term protection.
