How much does it cost to pull up and re-level settled interlock pavers on my Ottawa driveway?

Re-levelling settled interlock pavers is one of the most common driveway repairs in Ottawa, and the cost depends heavily on how much of the driveway is affected and what caused the settling in the first place.

Typical Re-Levelling Costs in Ottawa

For a small area (20 to 50 square feet) — a dip near the garage apron or a sunken patch at the end of the driveway — expect to pay $400 to $900. This involves lifting the affected pavers, adding and compacting additional base material, re-screeding the bedding layer, and reinstalling the pavers with fresh polymeric sand.

For a moderate section (50 to 150 square feet), costs typically run $900 to $2,500. If half or more of the driveway needs re-levelling, you're looking at $2,500 to $5,000+ for a standard double-wide driveway — at which point some contractors may recommend a full tear-out and rebuild if the base was inadequate from the start.

Why Interlock Settles in Ottawa

The most common causes in our climate:

• Insufficient base depth: Driveways installed with only 8 to 10 inches of base instead of the 14 to 18 inches Ottawa's frost line demands will settle within 2 to 4 winters. This is unfortunately common in subdivisions across Orleans and Barrhaven where builders cut corners on exterior work.

• Leda clay subsoil movement: Ottawa's notorious marine clay shrinks and swells with moisture changes. Without geotextile fabric separating clay from the granular base, clay particles migrate upward and compromise the base structure over years.

• Poor compaction during original install: If the base wasn't compacted in proper lifts (4-inch layers), it consolidates unevenly under traffic load and frost cycles, creating dips and humps.

• Drainage issues: Water pooling under one section of the driveway erodes the bedding sand and destabilizes the base. This is especially common where downspouts discharge near the driveway edge.

A skilled contractor can determine which option makes sense by examining the base after pulling pavers. If the Granular A and B layers are still at proper depth and well-compacted, a simple re-level of the bedding sand is sufficient. If the base itself has failed — voids, clay contamination, or insufficient depth — patching the surface is a temporary fix that will fail again within a year or two.

Timing Matters

Spring in Ottawa (April to May) is prime time for re-levelling because frost heave damage from winter is fully visible and contractors can address everything before summer use. Book early — experienced interlock repair crews in Ottawa fill up fast by March.
