Notre processus
Free On-Site Estimate
We visit your property to assess the area, soil conditions, drainage and your design preferences. We take precise measurements and discuss interlock styles, colours and budget. No charge, no obligation.
Detailed Quote & Material Selection
You receive a written quote covering excavation, granular base, interlock materials, labour and timeline. We bring samples so you can choose the right colour and pattern before work begins.
Excavation & Base Preparation
This is the most critical step. We excavate to the right depth, install 6 inches of compacted granular base and ensure proper drainage slope. A solid base is what makes interlock last 25+ years in Ottawa-Gatineau winters.
Installation & Finishing
Interlock is laid in your chosen pattern with precision cuts at edges and around obstacles. Polymeric sand is swept into joints and compacted. Complete site cleanup is included.
Conseils d'entretien & astuces
Winter maintenance: skip the rock salt
Sodium chloride (rock salt) accelerates joint erosion and surface deterioration. Use sand for traction or a calcium magnesium acetate deicer specifically labeled safe for interlocking stone.
Re-sanding joints every 3-5 years
Polymeric sand naturally compacts and washes out over time. If you notice gaps between pavers or weed growth in joints, a quick re-sanding prevents shifting and keeps the surface stable.
Sealing extends life and colour
A breathable polymeric sealer applied every 2-3 years locks in colour, repels stains and strengthens joint sand. Highly recommended for driveways subject to oil and tire marks.
Snowblower vs. shovel
Use a snowblower or plastic shovel to avoid scraping and chipping the interlock surface. Metal shovels can scratch and damage the finish, especially on textured or tumbled pavers.

Why interlock is the #1 choice for Ottawa-Gatineau driveways and patios
Ottawa-Gatineau gets some of the harshest freeze-thaw cycling in Canada. Here's why interlock consistently outperforms other surfaces in this climate. vs. Poured concrete: ✓ Local repairs possible — replace individual pavers without redoing the whole surface ✓ Handles freeze-thaw movement without cracking ✓ Better traction in winter (textured surface) ✓ More design variety ✗ Slightly higher upfront cost vs. Asphalt: ✓ Lasts 25+ years vs. 15–20 for asphalt ✓ No annual sealing required (asphalt needs it every 2-3 years) ✓ Dramatically better curb appeal and resale value ✓ No tar smell in summer heat ✗ Higher upfront investment vs. Natural stone slabs: ✓ More affordable ✓ Faster installation ✓ Better winter traction (less slippery when wet) ✗ Less "character" than natural stone The key to durability in Ottawa winters: a 6-inch compacted granular base + polymeric sand joints + proper drainage slope. That's exactly our standard on every project.
Ottawa vs. Gatineau side: Does it matter which side of the river?
We get this question often. Here's what's actually different between working on the Ottawa side vs. the Gatineau side. Permits: • Gatineau (Quebec): permit required for most interlock projects over a certain size. We handle all permit applications. • Ottawa (Ontario): permit requirements vary by ward and project type. We verify requirements for your specific address. Building codes: • Quebec (RBQ): We are licensed under the Régie du bâtiment du Québec (RBQ licence 5849-4857-01). • Ontario (Ottawa): We work in compliance with Ontario Building Code for hardscape projects on the Ottawa side. Pricing: no difference — our rates are the same on both sides of the river. Service area: We cover all of Gatineau (Aylmer, Hull, Buckingham, Masson-Angers), Ottawa proper, and surrounding communities including Kanata, Barrhaven, Nepean, Orleans and Cumberland. One contractor, both sides of the river, consistent quality.
