Low spots and dips
Pavers have settled below the surrounding surface or collect dirt and water.
Sinking & uneven pavers
Bring Sinking Interlock Back to Level.
We lift and reuse sound pavers, rebuild the failed area beneath them and restore a safer, cleaner grade.
Repair-first recommendationsLocal Ottawa service
Fix the cause beneath the surface
Uneven pavers are usually a symptom.
Interlock can sink when the base loses support, water moves material beneath the surface, or the edge restraint no longer holds the installation in place.
A focused repair starts by lifting the affected pavers and identifying why the area moved. Once the support and grade are corrected, sound pavers can be relaid into the original pattern.
Ask about your repairWhat to look for
Signs this repair may be needed.
A visible change in the surface can point to a problem with support, restraint or drainage beneath it.
Loose outside edges
Pavers spread or rotate because the edge restraint has shifted or failed.
Water near the house
The surface directs runoff toward the foundation instead of away from it.
Trip points
Adjacent pavers sit at different heights and create an uneven walking surface.
The repair process
Fix the problem in the right order.
Every repair begins with the condition beneath the surface—not with a coating or cosmetic shortcut.
- 01Inspect the failed area
Check the pattern of settlement, drainage direction, joints and edge support.
- 02Lift and save the pavers
Remove sound units carefully so they can return to the original installation.
- 03Rebuild the support
Correct the base, compaction, grade or restraint that allowed movement.
- 04Relay and finish
Restore the pattern, joint material and transition to the surrounding surface.
Repair-first approach
Keep the pavers. Rebuild only what failed.
Because interlock is modular, a settled area can often be repaired without replacing an otherwise sound patio, walkway or driveway.

Common questions
Before you request a quote.
Send photos and a short description if you are unsure which repair applies.
Can my existing pavers be reused?
Often, yes. If the units are structurally sound, they can be lifted, stored and relaid after the failed area beneath them is repaired.
Why did the interlock sink?
Common causes include weak base material, poor compaction, water movement, incorrect grading and failed edge restraints. The visible dip does not always identify the cause by itself.
Will adding sand level the surface?
Joint sand fills the spaces between pavers; it does not rebuild support beneath a settled area. Sinking pavers normally need to be lifted so the base can be corrected.
Can only one part of a patio be repaired?
A focused repair is often possible when the surrounding installation remains stable. The appropriate scope depends on how far the underlying failure extends.
