Interlock — Ottawa
Driveways built to last
a lifetime.
Interlock is the most durable and visually striking surface for Ottawa driveways, walkways, and patios. Unlike poured concrete, individual pavers can be lifted and reset if needed — and they handle Ottawa's freeze-thaw cycles beautifully.
The FENHAB difference
The Ottawa surface that gets better with age.
Engineered base system
Proper interlock starts below grade. We excavate, compact, and build a granular base engineered for Ottawa's frost depth.
Premium paver selection
Concrete pavers, natural stone, and specialty tumbled units — in dozens of colours, textures, and patterns.
Freeze-thaw resilient
Individual pavers move and flex with Ottawa's seasonal ground movement without cracking — unlike poured concrete.
Repairable for life
If a paver ever cracks or settles, individual stones can be lifted and replaced — no saw-cutting or patching.
Edge restraints and compaction
Polymer sand jointing and commercial-grade edge restraints prevent shifting, weeds, and washout.
Drainage solutions
We design for proper drainage to prevent puddling and protect adjacent landscaping and foundation areas.
Our process
How a FENHAB install actually goes.
- 01
Site assessment & quote
We review your driveway or patio area, discuss patterns and stone options, and provide a detailed quote.
- 02
Excavation & base
Excavated to proper frost-depth, sub-base compacted in lifts, drainage established.
- 03
Stone laying & pattern
Pavers laid to your chosen pattern, cut to edges, compacted, and sand-set.
- 04
Edge, grout & seal
Polymer jointing sand applied and compacted. Optional sealant applied to protect finish.
FAQ
Answers, before you ask.
- How does interlock handle Ottawa winters?
- Interlock is specifically well-suited to freeze-thaw climates. Individual pavers can shift slightly without cracking — unlike poured concrete which cracks under ground movement.
- How long does an interlock driveway last?
- A properly installed interlock driveway with an engineered base regularly lasts 25–40 years with minimal maintenance.
- Can I pressure-wash interlock?
- Yes — moderate pressure washing is safe for interlock. After washing, refresh the jointing sand and apply sealant for best results.
- What is the cost difference between interlock and poured concrete?
- Interlock is typically 20–40% more expensive initially but offers significantly lower lifetime costs due to repairability and longevity.
