How much does it cost to re-sand and re-level an interlock driveway in Kanata?

Re-sanding and re-leveling an interlock driveway in Kanata typically costs $8 to $15 per square foot, meaning a standard 400-500 square foot driveway runs $3,200 to $7,500 depending on the extent of settling and access conditions.

The cost varies significantly based on how much releveling is required. Minor releveling where only sections have settled 10-20mm costs on the lower end, while major releveling involving extensive base repair, adding granular material, and re-compacting can reach the higher range. Kanata's mix of clay soils (especially in older sections like Kanata Lakes) and sandy soils (in newer developments) affects how much base work is needed.

What's included in professional releveling: The contractor lifts the affected pavers with specialized tools, adds and compacts bedding sand or granular base material as needed, ensures proper drainage slope (minimum 2% away from the house), relays the pavers in the original pattern, and applies fresh polymeric sand to lock the joints. In Ottawa's freeze-thaw climate, this work must address the root cause of settling — usually inadequate base compaction or water infiltration — not just the surface symptoms.

Kanata-specific considerations make this work particularly important. Many Kanata driveways were installed during the rapid development of the 1990s and 2000s when some builders used minimal base preparation. The clay subgrade common in areas like Kanata Lakes expands and contracts dramatically with moisture changes, while the freeze-thaw cycles (50+ per winter) gradually work pavers loose. Kanata's newer subdivisions often have better base preparation, but even well-built interlock requires releveling every 10-15 years as the base naturally settles.

Re-sanding alone (just replacing polymeric sand without lifting pavers) costs $2 to $4 per square foot and should be done every 3-5 years in Ottawa. However, if pavers have settled more than 10mm or you see significant gaps between units, full releveling is necessary. Attempting to just re-sand settled pavers creates trip hazards and allows water infiltration that accelerates further settling.

DIY considerations: Homeowners can handle re-sanding if the pavers are level, but releveling requires proper equipment — plate compactors, levels, and often additional granular material. The physical work of lifting and relaying hundreds of pavers is substantial, and improper compaction leads to recurring settlement within 1-2 winters.

Timing matters in Ottawa — this work should be done between May and October when the ground is stable and materials can cure properly. Many Kanata homeowners schedule releveling in late summer after identifying settlement issues from spring thaw.
