Interlock repair and re-levelling.
FOUR40 lifts, re-bases and resets sunken or heaved interlock across the GTA, replaces failed edge restraint and re-sands joints with polymeric sand. Often the honest answer instead of a rebuild. Free on-site estimates.

Before we start
Written scope
On site
Same crew throughout
What's included
Fix the cause, not the symptom.
A settled area of interlock is a base problem showing through the surface. Resetting the pavers without correcting what is underneath means doing it again in two years.
The repair
- Affected area lifted and stacked
- Base corrected and compacted in lifts
- Bedding re-screeded
- Same units reset to line
- Joints re-sanded
Maintenance work
- Polymeric sand re-sanding
- Edge restraint replacement
- Weed and moss clearing
- Sealing where wanted
- Drainage corrections
Cheap, and it postpones the expensive version.
What it costs
What moves the number.
Typical range
Ask for a figure
We publish real numbers rather than "it depends" — but only once they're ours to publish. Our written ranges are being finalised; call and we'll give you one over the phone in a minute. What moves the number:
- Area affected, and whether it is one patch or several
- Why it failed — surface reset versus base rebuild
- Access for materials and spoil
- Whether any drainage work is needed to stop it recurring
- Whether matching units are still available
- Re-sanding and edge restraint across the rest of the surface
Working with us
Five steps, no surprises.
01
Site visit
We measure, check drainage and grade, and talk through what you actually want. Free, and no pressure to sign anything.
02
Written quote
Scope, materials, base depth and price in writing. You'll know exactly what's included before a shovel moves.
03
Schedule & locates
Ontario One Call locates booked, materials ordered, start date confirmed. A realistic window, not an optimistic one.
04
Build
Excavation, base, compaction, install. Site cleaned at the end of each day — you still have to live there.
05
Walkthrough
We walk it together before final payment. Anything on your list gets fixed, then we're back if settling shows up.
Questions
Questions, answered.
Can a sunken driveway be fixed without replacing it?
Very often, yes. If the pavers themselves are sound, the affected area is lifted, the base beneath it is corrected and re-compacted, and the same units go back down. It costs a fraction of a rebuild and, done properly, does not come back.
Why did it sink in the first place?
Nearly always the base: too shallow, poorly compacted, or with no separation from the soil beneath. Sometimes it is drainage — water running to the wrong place and washing fines out from under the surface. We work out which before quoting, because fixing the surface without fixing the cause just buys time.
When is a repair not worth it?
When the whole driveway is moving rather than one area, when the pavers are 60 mm units under vehicle load, or when the base is so thin that lifting one section reveals the same problem everywhere. We will tell you that rather than sell you a repair we expect to be back for.
What about the joints and edges?
Re-sanding with polymeric sand and replacing failed edge restraint is the other half of maintenance work, and it is cheap. Open joints and creeping edges are what turn a tidy driveway into a scattered one.
