Interlock Driveways, Engineered for Ottawa.

Your driveway carries two tonnes of steel over frost-heaved clay 200 times a year. Ours are built 12 inches deep so they stay flat through Ottawa winters — and look better than asphalt every single year after.

Why Driveways Fail

Asphalt cracks. Gravel ruts. A proper paver driveway just stays flat.

Most Ottawa driveways fail for one reason: the base was too shallow for our frost. Asphalt cracks at the edges within five winters. Poured concrete spalls under road salt. A paver driveway built on 12 inches of compacted HPB handles the same freeze-thaw cycles for 25 years or more — and if a single paver is ever damaged, you replace one stone, not the whole slab.

Every EcoWave driveway is excavated to a full 12 inches, compacted in lifts, and finished with polymeric sand that locks the joints against weeds, ants and salt. We pitch every surface away from your garage at a minimum 2% so meltwater never pools at the door.

  • Full 12" excavation — the driveway spec, not the walkway spec
  • Geotextile separation fabric over clay subgrade
  • HPB limestone compacted in 4" lifts
  • 2%+ drainage pitch away from the garage
  • Concrete haunch or aluminum edge restraint
  • Polymeric joint sand + optional sealer
Driveway Projects

Every Layout. One Build Standard.

Double Driveways

Full 2-car and 3-car replacements with reinforced auto-grade base and border courses that frame the house.

Driveway Widening

Add a parking lane or walkway strip to an existing driveway — tied in so old and new settle together.

Borders & Inlays

Soldier-course borders, contrasting inlays and apron details that make a standard lot look custom.

Asphalt Replacement

We demo and haul the old asphalt, correct the base, and finish in pavers. Most swaps take 5-7 days.

Front Steps & Landings

Matching stone steps and landing pads tied into the driveway build — no settling gap at the garage.

Heated-Driveway Ready

Base prep and conduit runs for future snow-melt systems, so you never rip up finished pavers.

FAQ

Driveway Questions.

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

How much does an interlock driveway cost in Ottawa?
Most Ottawa interlock driveways land between $28-$42 per square foot installed. A typical 600 sq ft two-car driveway runs $17,000-$25,000 depending on paver line, borders and site access. Every EcoWave quote is fixed-price and itemized — the number we write is the number you pay.
How long does a paver driveway last in Ottawa?
Properly based interlock lasts 25 years or more in Ottawa freeze-thaw conditions. The pavers themselves carry a manufacturer lifetime warranty; our 12-year workmanship warranty covers the base — the part that actually fails on cheap installs.
Can you widen my existing driveway?
Yes. We excavate the new strip to the same 12-inch depth, tie the base layers together, and match or complement your existing pavers. Widening projects usually take 2-4 days.
Will pavers handle Ottawa road salt?
Modern Techo-Bloc, Permacon and Unilock pavers are rated for de-icing salt. The weak point is joint sand, which is why we finish with polymeric sand that hardens. Re-sealing every 3-4 years keeps the surface protected.
Can interlock be installed before winter?
Our season runs late April through mid-November. We stop installing once overnight temperatures stay below freezing, because polymeric sand and base compaction need frost-free conditions to cure correctly.
Do you remove my old asphalt driveway?
Yes — demolition, haul-away and dump fees are included in the fixed quote. Old asphalt is recycled, not landfilled.
