Sinking Pavers? We Lift, Re-Base, Re-Lay.

A sunken driveway or heaved walkway usually does not need a tear-out. We lift your existing pavers, rebuild the failed base properly, and re-lay the same stones — most jobs are done in 1-3 days at a fraction of replacement cost.

Before You Tear It Out

If a contractor quoted you a full replacement, get a second look.

Nine times out of ten, sunken interlock is a base problem, not a paver problem. The original installer went too shallow, skipped the geotextile, or compacted in one lift — and Ottawa frost did the rest. The pavers on top are usually fine and worth keeping.

A relevel costs a fraction of a full replacement because you keep your pavers. We lift the affected area, excavate to proper depth, compact new HPB in lifts, and re-lay your stones with fresh polymeric sand. Where pavers are cracked or discontinued, we blend in matching or complementary replacements.

  • Keep your existing pavers — pay for base, not stone
  • Lift, re-base and re-lay sunken sections
  • Edge restraints rebuilt so it stops creeping
  • Fresh polymeric sand locks out weeds and ants
  • Broken pavers replaced with matched stock
  • Most driveways done in 1-3 days
Repair Services

Fix the Base. Keep the Stone.

Releveling Sunken Sections

Car ruts, dips and birdbaths lifted and re-based to the correct 8-12 inch depth — the area comes back level and stays level.

Heaving & Frost Damage

Sections pushed up by frost are lifted, the contaminated base is replaced, and the surface is reset to grade.

Edge Restraint Repair

Creeping borders and spreading edges re-pinned with concrete haunch or aluminum spike restraint.

Re-Sanding & Weed Control

Old joint sand blown out, weeds and ant hills removed, joints refilled with hardened polymeric sand.

Drainage Correction

Low spots that pool water against the garage or foundation re-pitched to drain the right way.

Step & Landing Repair

Rocking or settled front steps re-based and reset so the gap at your door disappears for good.

Repair or Replace?

The 30% Rule of Thumb.

This is the honest framework we use during free assessments. If your project falls in the replace column, we will tell you — and quote both options so you can decide with real numbers.

  • Repair makes senseUnder ~30% of the surface is sunken or damaged
  • Repair makes sensePavers are intact and the pattern is worth keeping
  • Repair makes senseFailure is localized: ruts, edges, one corner
  • Replace makes senseBase failed across the whole surface
  • Replace makes sensePavers are badly spalled, scaled or discontinued
  • Replace makes senseYou want a new layout, size or paver line
  • Either wayFree on-site assessment, written quote both ways

FAQ

Repair Questions.

Straight answers before you book. Don't see yours? Call (343) 998-8316.

Why is my interlock sinking in the first place?
Almost always a shallow or poorly compacted base. If the original installer excavated less than 8 inches for a driveway — or skipped compaction lifts — Ottawa frost heaves the surface within a few winters. Car ruts form where the base is thinnest. We fix the base depth so it does not happen again.
How much does interlock repair cost compared to replacement?
Releveling typically costs a fraction of a full replacement because you keep your existing pavers — you are paying for labour and base material, not new stone. After a free on-site assessment we give you a fixed written price, and if replacement is genuinely the better value, we say so.
Will the repaired section match the rest of my driveway?
Your original pavers go back in the same pattern, so colour and layout match. Fresh polymeric sand can look slightly brighter for a few weeks until it weathers in. Where individual pavers are broken, we source the closest match from the same manufacturer line.
How long does a repair take?
Most driveway relevels take 1-3 working days depending on the size of the failed area. You can usually park on the repaired section 24 hours after the polymeric sand is set.
Will the weeds come back?
Not from below. Weeds root in the organic-filled joints, not under the pavers. We remove the contaminated sand and refill with polymeric sand, which hardens to block weeds and ants for years. Occasional wind-blown seeds on the surface are a quick rinse, not a re-infestation.
Can you fix a driveway another company installed?
Yes — most of our repair work is fixing other installers shallow bases. We do not need the original plans or warranty; the free assessment tells us everything we need from what the ground is doing now.
