Interlock Driveway Repair Ottawa | Polymeric Sand

Our Driveway Repair Process

A rigorous 4-step method built for the wear a driveway takes

01

Free Evaluation

We come to your property to assess your pavers and give you a transparent price, no surprises. We always protect the lawn, flower beds and everything around the work area before starting.

02

High-Pressure Cleaning

Complete removal of the old polymeric sand and a deep pressure wash to clear moss, stains and debris. Our professional pressure washer (3600 PSI, 2.5 GPM, industrial Honda engine) lifts deep-set grime without damaging your pavers.

03

New Polymeric Sand

We apply Techniseal HP NextGel polymeric sand into every joint — always this premium product, regardless of the project. Frost, weed and insect resistant, once cured it forms a barrier that keeps weeds and ants from settling between the joints.

04

Activation & Finishing

Water activation to cure the sand. Sealant option available for maximum protection and a glossy finish. We use Techniseal sealant, a trusted brand, for lasting protection and a finish that brings your pavers' colours back to life. We carefully clean the work site and adjacent surfaces before we leave — you have nothing to pick up.

Signs It's Time to Repair Your Interlock Driveway

A driveway takes more punishment than a patio: vehicle weight, de-icing salt and constant traffic. Here are the most common signs we see on driveways around Ottawa and Gatineau.

The joint sand has disappeared or become loose. The pavers shift when a car drives or parks on them.
Weeds or moss keep growing back between the pavers, even after you pull them out.
The colour is faded or stained by de-icing salt, oil or built-up dirt.
The existing sealant is peeling, yellowing or flaking off in patches.
Ants or other insects are settling into the joints between the pavers.

If you recognize one or more of these signs, your driveway likely needs a deep clean, fresh polymeric sand and possibly sealant. That's exactly what we do.

Frequently Asked Questions — Driveway Repair

Everything you need to know before contacting us.

A project generally takes 2 to 3 days: at least 2, and usually 3 with sealer. We'll give you a precise timeline during the free visit.

We redo the full surface. The pressure washing and polymeric sand are done across the whole driveway rather than in sections, which is what gives you an even colour and joints that age at the same rate. You get the exact price at the free on-site visit.

Techniseal HP NextGel, on every project. We've tried Sika, RG+, EZ and HP NextGel: HP NextGel is more consistent, leaves less haze on the pavers and lasts longer. A job done right stays weed-free for 3 to 5 years.

According to Techniseal, you can walk on HP NextGel right away. For your car, wait 48 to 72 hours while the joints dry.

Yes, a 12-month guarantee on our work. All the details are written in your contract, which you can read before you sign.

The price depends on the size and condition of your driveway, generally between $600 and $4,000. We offer free on-site quotes — call 819 328-2129.
