Ottawa Interlock Driveways

Exceptional Build Quality

When we build Ottawa interlock driveways we deliver quality work built on a deep foundation that is guaranteed to perform for years to come.  Digging deep enough foundations, specified aggregate compaction and using interlock edging means our interlock projects perform better over time. From Orleans to Kanata A&Z has installed driveways across the city of Ottawa.

The A&Z Interlock Driveway Difference

  • 100% warrantied or we don’t take the job
  • 12-inch granular gravel (GA) foundation
  • Excellent compaction of the base to ensure no settling
  • Stone dust to layer to deliver a level surface
  • Interlock edging is installed preventing sunken edges
  • Customizable (paver size, colour, pattern, border, etc).
  • Backfill around perimeter
  • G2 Polymeric sand for strong joints and no weeds

Installing foundations to industry specification, using edging constraints and ensuring maximum compaction our Ottawa interlock driveways stand the test of time and look amazing for years to come. 

With easy access driveways are the perfect job to squeeze in the spring or fall. Schedule your Ottawa interlock driveway today.

How Does An Interlock Driveway Compare To Asphalt?

Interlock is superior to asphalt in almost every way. 

When comparing interlock to other driveway construction materials they just do not compare.

Asphalt is very soft and pliable on a warm summer day

If you park a trailer on your driveway on a hot day and the driveway will be permanently scarred.  Even light-duty trucks can leave a dent in your asphalt.  Easily preventable by distributing the load with a block of wood but mistakes happen.

Lost aggregate & cracking over time

As interlock ages, it remains smooth and level but asphalt driveways continually lose aggregate creating a rough surface.  When water penetrates your driveway and freezes it cracks.  Once damages asphalt cannot be restored to its original beauty.


Maintenance & Sealing

Asphalt require sealing at least every 24 months to keep it looking nice.  A 2 car driveway slurps up 4 buckets of DIY sealer and the consumer-grade products just don’t perform.

Performance vs. Cost

Because of the labour and material, interlock does have a higher initial cost.  But when you compare the cost over 25-50 years interlock offers far better value despite the higher initial investment.

If cost is an issue often-times customers opt for a driveway extension.  Widening your driveway on either side with an interlocking design of your choosing.  This allows for extra parking and seriously improves the curb appeal of your home. 

Interlock Driveway Testimonial

Working with Sarah was a great pleasure for A&Z Interlock.  She interviewed many interlock contractors in Ottawa.  With each meeting, she knew the design solution for her unique grading issue wasn’t right for her. Our experience allowed us to identify the grading issue, recommend a design that would work on her property and she was very happy with the results.

City of Ottawa Driveway Zoning, Easements & By-Laws

Some properties in Ottawa are prohibited from widening their driveways because of zoning and regulation.  Interlock driveways allow home-owners to circumvent these regulations because interlock is considered temporary and can be removed and replaced.  We understand that family parking in a single lane driveway can be a pain and our team provides creative solutions to your parking trouble. 

Interlock Driveway Design

Our skilled and experienced designer schedules a time to meet in your home and discuss the possibilities for your new driveway. Together we compare other landscaping elements and features of your house.  This meeting ensures A&Z Interlock delivers a final product you will love!

Factors we consider are slope, grade, drainage and of course the utility of the area. Let us guide you through the process of choosing your preferred interlock paver size, colour and patterns. 

Our team is highly professional and we never sacrifice quality on materials or cut corners during installation.  Our commitment to quality workmanship is demonstrated through our warrantied work.  We know you will love working with us so let’s start today!
