Our Ottawa interlock repair crews handle the full range of paver issues: sunken sections, lippage, weeds and ants in the joints, failed polymeric sand, broken or stained pavers, missing edge restraints, and settling near downspouts. We lift the affected pavers, correct the base, reset, and finish with fresh polymeric sand.
Sunken pavers and loose steps are almost always a base or drainage problem. We rebuild the bedding so the fix lasts.

Lifted and re-laid two sunken sections plus re-sanded the whole driveway. Looks like new and didn't cost anywhere near a full replacement.
Three years in and still no settling, no weeds. Used Techo-Bloc with a darker border. Multiple neighbours asked who did it.

View projectIf your driveway was installed 10+ years ago, the original paver line may be discontinued. We carry reserve stock and source close matches so your repair blends in.
Kanata. Lift-and-relay and full repair across Kanata Lakes, Bridlewood, Morgan’s Grant, Beaverbrook, and Katimavik. Frost-heave on undersized builder bases is the most common Kanata failure we fix — $1,500-$4,000 typical relevel.
Barrhaven. Repair work across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Most Barrhaven repairs are sunken sections near downspouts — we fix the drainage as part of the repair.
Orleans. Sunken paver relevel across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Older Orleans driveways often have failed polymeric sand — we vacuum out and replace.
Nepean. Repair work across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean trees mean root-lifted pavers — we cut the root, regrade, and relay.
Stittsville. Section relevels across Jackson Trails, Crossing Bridge Estates, and Amberwood. Larger Stittsville driveways often need multi-section relevels — $3,000-$6,000 typical.
Gloucester. Repair work across Beacon Hill, Blackburn Hamlet, and Hunt Club. Gloucester driveways exposed to heavy road salt need re-sanded joints every 3-5 years to keep weeds and ants out.
Manotick. Estate driveway repair across Mahogany, Manotick Estates, Long Island, and Manotick Village. Long Manotick drives often have isolated settled sections — we spot-repair instead of full rebuilds.
Riverside South. Repair work across Honey Gables and the Riverside South village. Newer Riverside South pavers usually only need a relevel and re-sand, not full rebuild.
Centretown. Tight-access repair across the Golden Triangle and Centretown West. Heritage walks, rear-laneway pavers, condo courtyards — we bring small equipment.
Westboro. Heritage repair across Westboro Beach, Highland Park, and McKellar Park. Period-correct paver matching is part of the work — we source the closest discontinued line or recommend a contrasting border solution.
Alta Vista. Repair and relevel across Heron Park, Faircrest Heights, and Playfair Park. Root pressure and mature tree canopies cause a lot of Alta Vista uplift — we address the root cause.
The Glebe. Heritage repair across the Glebe and the Old Ottawa South border. Narrow lots, neighbour-shared walks, original heritage pavers — colour matching and access coordination are part of the work.
Most interlock repairs in Ottawa fall between $1,500 and $5,000 depending on the size of the affected area, base condition, and whether replacement pavers are needed. Small spot repairs may start around $800.
Most settled driveways can be repaired by lifting the affected pavers, correcting the base, and resetting. Full replacement is only needed when base failure is widespread or when pavers are too damaged to reuse.
Common causes are inadequate base depth, poor compaction during installation, washouts from downspouts, broken weeping tile, or improperly compacted utility trenches under the pavers.
We pressure-wash or vacuum out old joint sand, replace any failed pavers, and refill the joints with polymeric sand that hardens to resist weed growth and ant tunnels.
Most spot repairs are completed in 1 working day. Section relevels take 1 to 3 days, and full driveway or patio relevels take 3 to 5 days depending on size.
We try to match the closest available paver if replacements are needed. If your paver line has been discontinued, we recommend creative solutions like contrasting borders or inlays.
For Ottawa we recommend premium polymeric sands from Techniseal, Alliance Gator, or similar. These hold up to freeze-thaw cycles and Ottawa snow-clearing.
Yes. Sunken pavers under downspouts are common in Ottawa. We address the underlying drainage issue — usually by extending the downspout discharge — before resetting the pavers.
