Interlock Repair & Releveling in Toronto & the GTA
Lift, relevel, and restore settled or heaved interlocking pavers — usually in a single day per section.
Interlocking pavers can last 30+ years in the GTA when installed correctly, but most installs from the 2000s and 2010s are now showing the wear of two decades of freeze-thaw cycles: settled sections, wash-out joints, weed-filled gaps, sunken patio corners, and tilted driveway edges. The good news is that interlock is uniquely repairable — pavers can be lifted, the base relevelled, and the same pavers reinstalled with fresh polymeric sand, often at 25-40% of the cost of full replacement. The most common GTA failure modes are root heaving from mature maple and silver birch trees (Toronto's tree canopy bylaws mean most homes have at least one mature tree near hardscape), polymeric sand wash-out from improper compaction or aggressive pressure washing, and base settlement from inadequate compaction during original installation. Buildoreno repairs interlock across Toronto, Etobicoke, Scarborough, Mississauga, and Vaughan — from small spot repairs to full driveway or patio restorations. We diagnose the cause (because relevelling a section that has a root problem just means re-heaving in 2 years), lift the affected pavers, address the underlying issue, recompact the base, replace any broken pavers from inventory, and finish with fresh polymeric sand that locks the joints against weeds and ants. Where the pavers have faded badly from UV exposure, we offer a flip-and-clean service where pavers are turned over to expose the fresh underside surface for a like-new appearance without buying new stone.

Our process, step by step
- 1Diagnosis & Estimate
We inspect the failed area to identify the root cause: root heave, base settlement, water erosion, or sand wash-out. The repair scope and pricing depend on the cause — fixing the symptom without addressing the cause leads to repeat failure.
- 2Paver Removal
Affected pavers are carefully lifted using extraction tools, numbered if necessary to preserve a pattern. Damaged pavers are set aside for replacement from our colour-matched inventory of common GTA paver styles.
- 3Base Repair & Releveling
Settled base material is removed and replaced with fresh limestone screenings. Tree roots are pruned (with arborist approval if the tree is bylaw-protected) or root barriers are installed. Base is recompacted to original specification.
- 4Paver Reinstallation
Original pavers are reinstalled in the same pattern, with replacements added where needed. Each paver is leveled and seated. Edge restraints are checked and replaced if they've failed.
- 5Polymeric Sand & Compaction
Polymeric sand is swept into joints, the surface is compacted with a plate compactor with a urethane pad to seat pavers without scratching, and the sand is activated with a fine water mist that hardens it into a flexible bond.

Interlock Repair & Releveling questions, answered
Spot relevelling typically costs $25-$50 per square foot, with a $400-$600 minimum for small repairs. Full driveway or patio restoration (lift, relevel, polymeric sand) runs $8-$15 per square foot — far less than the $25-$45 per square foot of new installation.
Three main causes: tree roots growing under the base and lifting pavers (common with mature maples in older Toronto neighbourhoods), inadequate base compaction during original install (common in 2000s-era builds), and water erosion from poor drainage washing out the bedding sand. We diagnose the cause before quoting repair.
Yes, in two ways. Pavers can be flipped over to expose the fresh underside — labour-intensive but produces a like-new appearance at a fraction of replacement cost. Alternatively, sealers in tinted or wet-look formulas can restore colour for 3-5 years per application.
Properly installed polymeric sand lasts 5-7 years before refresh is needed. It fails faster (2-3 years) when applied incorrectly — too much water during activation, sand left on paver surfaces, or aggressive pressure washing. Our refresh process removes the old sand and installs new.
When the root cause is addressed, the repair lasts as long as the original install — typically 15-25 years more. Repairs that only level the surface without fixing the base or root issue will heave again within 1-3 years.
