Interlock Repair
Why replace everything when you can repair it?
Is your interlock driveway sinking? Are your stone steps crooked and wobbly? Good news: in most cases, there’s no need to tear everything out. Dura-Tech gives your interlock a second life — at a fraction of the cost of a brand-new installation.
Has Your Interlock Seen Better Days? We’ll Set It Straight.
Time, water and our Canadian winters are merciless on interlock. Year after year, the ground shifts, the base settles… and your once-beautiful landscaping turns into an obstacle course.
Does this look like your property?
- A driveway full of dips and bumps where water pools
- Pavers that heave, sink or shift out of place
- Stone steps that lean and have become a safety hazard
- Edge restraints pulling apart, letting the pavers spread open
- Polymeric sand long gone, replaced by weeds and ants
- A patio that’s become uneven and unstable
These problems aren’t just cosmetic: uneven pavers and crooked steps are a tripping hazard for your family and guests — and the situation only gets worse with every winter.
Repair Instead of Replace: It Just Makes Sense
Here’s what most people don’t realize: in the vast majority of cases, your pavers are still in perfect condition. It’s the base underneath that has shifted.
So why pay for brand-new materials when yours can still last for decades?
Save big
Repairing costs a fraction of a full replacement. We reuse your existing pavers — you pay for the expertise, not for materials you don’t need.
Keep your look
Is your paver model discontinued? No problem. By reusing your original pavers, the result is seamless — no mismatched “patch” in a different colour.
A faster job
A repair takes days, not weeks. Less noise, less dust, less disruption.
An eco-friendly choice
Reuse instead of throwing away: tons of material kept out of the landfill.
Our Repair Services
Interlock releveling
We carefully lift the sunken pavers, rebuild the base (crushed stone and stone dust, properly compacted to industry standards), then relay your pavers perfectly level. The problem is fixed at the source — not just covered up.
Stone step and landing repair
Leaning steps, shifting stones, wobbly landings: we straighten and secure your outdoor stairs so they’re safe and welcoming again.
Edge restraint repair
Edge restraints are the backbone of your interlock. When they fail, everything else follows. We re-anchor them solidly so your installation stays put.
Damaged paver replacement
Cracked, chipped or stained pavers? We replace only the damaged units, matched to blend in with the rest.
Polymeric sand rejointing
Once the pavers are releveled, we refill the joints with quality polymeric sand: no more weeds, ants or joint erosion.
Drainage correction
Water pooling in the wrong place is often the root cause. We correct the grading to direct water away from your home and prevent future settling.
Why Does Interlock Shift in the First Place?
Understanding the problem is the key to fixing it for good:
- Freeze-thaw cycles — water seeps under the pavers, freezes, expands and heaves everything in its path
- A poorly compacted base — a deficient original installation always shows eventually
- Erosion — rainwater gradually washes away the sand and base material
- Traffic — the repeated weight of vehicles compresses the ground over the years
That’s why a real repair isn’t just about resetting pavers: at Dura-Tech, we fix the base and the drainage so the results last.

Frequently Asked Questions
How much does interlock repair cost?
It depends on the area and the extent of the damage, but a repair generally costs far less than a full replacement. The assessment and quote are free.
Will the repaired area stand out?
No. Since we reuse your existing pavers, the repaired section blends perfectly with the rest. After cleaning and rejointing, the whole surface regains its original look.
How long does the work take?
Most residential repairs are completed in one to three days, depending on the area.
Will the repair last?
Yes — because we fix the root cause of the problem, the base and the drainage, not just the appearance. That’s what separates a professional repair from a quick patch job.
What time of year can interlock be repaired?
From spring to fall. Spring is ideal: after the thaw is when the full extent of ground movement becomes visible.
Is it better to repair or replace?
If your pavers are in good condition, repairing is almost always the better choice. If the materials are at the end of their life or you want a whole new style, replacement becomes worthwhile. During the assessment, we’ll give you honest advice on the best option.
