Interlock Repair

Interlocking stone driveways in Ottawa inevitably require maintenance as years of freeze-thaw cycling, heavy snowfall, and plow contact take their toll.

The most common issues Ottawa homeowners face are sunken or heaved pavers caused by base settlement or frost movement, displaced pavers from plow blade impact, deteriorated polymeric sand allowing weed growth and ant infiltration, and efflorescence — the white mineral deposits that appear on paver surfaces after moisture migrates through the stone.

Professional interlock repair in Ottawa begins with lifting the affected pavers, assessing and correcting the base material and bedding sand underneath, re-levelling the surface, and reinstalling the pavers with fresh polymeric sand.

In areas with particularly poor drainage or clay-heavy soil — common throughout much of Ottawa including Kanata, Stittsville, and the south end — contractors may need to improve the granular base depth or add drainage solutions to prevent the same settling from recurring. Plow-damaged pavers can usually be individually replaced without disturbing the surrounding surface, one of the key advantages of interlocking systems.

Re-sanding the entire driveway with polymeric sand every three to five years is a preventive maintenance step that keeps joints tight, inhibits weed and insect penetration, and maintains the structural interlock between pavers.

Our matched Ottawa interlock repair contractors also handle colour-matching replacement pavers for discontinued product lines and can restore faded surfaces with paver-specific sealers that enhance colour and provide additional protection against salt staining and freeze-thaw weathering.
