What is interlock repair?

Over time, interlock surfaces can develop sunken spots, shifted pavers, cracked edges, or loose border stones, often caused by base erosion, tree roots, poor drainage, or normal wear. Our repair service addresses the root cause, not just the surface. We lift and remove affected pavers, assess and rebuild the base where needed, re-compact, and re-lay the stones so the surface is level, stable, and safe again. We also replace damaged pavers, tighten edge restraints, and resand joints. Whether it's a small trip hazard on a walkway or a larger section of driveway that's settled, we'll restore it to look and perform like it should. Repairs are usually completed in a day or two depending on scope.

Our process

A clean finish starts with the steps you do not see. We build from the base up.

Step 1

Assessment

We identify why the area failed (water, base, or edging).

Step 2

Lift + rebuild base

We pull pavers, correct grade, and compact layers properly.

Step 3

Reinstall + jointing

We reinstall, cut cleanly, and re-sand joints for lock-in.

Pricing factors

Exact pricing depends on the project. These are the main drivers:

Area size and severity of sinking/shift

Whether base rebuild is needed

Drainage corrections required

Replacement pavers (if existing are broken/unavailable)

Edge restraint and border repairs

FAQ

Common questions about interlock repair.

+Why does interlock sink?
The most common reason is that the base underneath wasn't compacted properly when it was originally installed, so over time it settles unevenly. Water is another big factor, especially in Ottawa where freeze-thaw cycles can wash out base material and create voids under the pavers. Failing edge restraints can also let the whole system shift outward, which creates gaps and low spots.
+Can you match existing pavers?
In most cases, yes. If the original paver is still being manufactured, we can source the same product for a seamless repair. If it's been discontinued, we'll find the closest match available or we can use a contrasting paver as a feature border to make the transition look intentional rather than patched.
+Is re-leveling better than replacing?
If your pavers are still in good condition and just the base has failed, re-leveling is almost always the smarter move. It costs less than a full replacement and gives you a solid result. We'll assess the pavers during the repair and let you know honestly if any need to be swapped out.
+How long do repairs take?
Small repairs like a sunken section of walkway can often be done in a few hours. Larger areas that need base rebuilding or drainage corrections might take 1 to 2 days. We'll give you a clear timeline after the initial assessment so you know what to expect.
+Will the repaired area look different?
We do our best to blend the repair into the surrounding surface so it's not obvious. There can be some slight colour variation if the existing pavers have weathered over the years, but a good cleaning or sealing of the full area usually brings everything together. Most homeowners are surprised at how well it matches.
+Do you fix pooling water?
Yes, pooling water is one of the most common issues we deal with. We can regrade the affected area to create proper slope, add drainage features if needed, and make sure water is moving away from your home's foundation. Fixing the drainage is important because standing water is usually what caused the damage in the first place.
