Interlock restoration before and after — pressure washing and re-sanding driveway in Ottawa
Why Restore

Most Ottawa interlock can be saved — no demo required.

If your driveway, walkway or patio looks tired but the pavers themselves are still solid, you almost certainly don't need to rip it out. Faded color, weed-filled joints, sunken pavers, washed-out sand — these are surface issues. We address them in a 2-3 day restoration that costs 25-40% of a full rebuild.

The exception: if the base has failed (soft spots, deep waves across more than 30% of the surface), restoration is a band-aid. We'll tell you honestly during the on-site assessment — even if it costs us the job.

FAQ

Restoration Questions.

How do I know if my interlock can be restored vs. needs a rebuild?
If the pavers are intact and waves are localized (<30% of surface), restoration is the right call. If you've got soft spots, deep dips across most of the driveway, or visible base failure, you need a rebuild. We give you the honest answer on-site for free.
How much does interlock restoration cost in Ottawa?
Typical range is $3-$7 per square foot. A standard 2-car driveway runs $1,800-$4,200 depending on how many pavers need lifting and replacing. Roughly 25-40% of a new install.
How long does a restoration take?
2-3 days for most driveways. Day 1: lift & pressure wash. Day 2: re-level, replace damaged pavers. Day 3: polymeric sand. Patios and walkways are usually 1-2 days.
What's polymeric sand and why does it matter?
Polymeric sand is silica sand mixed with a binder that hardens when wet. It locks pavers in place, blocks weeds and ants, and resists Ottawa road salt. Regular play sand washes out within a season — polymeric lasts 5-7 years.
Will the color come back to faded pavers?
Pressure washing alone restores 60-70% of original color. The optional penetrating sealer ($1.50-$2.50/sq ft) brings it back to nearly new and enriches the tone. Sealer also blocks future salt damage for 3-4 years.
Can you match older paver styles for replacements?
Most Techo-Bloc, Permacon, Unilock and Oaks lines from the last 15 years are still available or have close matches. We bring samples to the on-site visit to confirm before quoting.
Do you handle the weed and moss problem?
Yes — hot pressure wash kills weed roots, then polymeric sand prevents re-growth. Most clients see no joint weeds for 5+ years after a proper restoration.
