Elegant Curb Appeal & Expanded Space
INTERLOCK DRIVEWAYS & EXTENSIONS
Transform the face of your home with the timeless beauty and unmatched versatility of interlocking stone. At Coliseum Concrete & Interlock Services, we design and install custom interlock driveways that combine high-end aesthetics with the rugged durability needed for Ottawa’s climate. Whether you want to replace an old asphalt surface or require a seamless driveway extension to accommodate an extra vehicle, our team delivers precision-crafted results that instantly elevate your property’s market value.
Our secret to a long-lasting driveway lies beneath the surface. We specialize in industrial-grade base preparation, using multi-layered compaction and high-performance geotextiles to prevent the shifting, dipping, and rutting common in lesser installations. By choosing premium stones and polymeric jointing sand, we create a flexible yet rock-solid surface that resists weeds and handles heavy vehicle loads with ease. From classic herringbone patterns to modern oversized pavers, we build driveways that are as functional as they are visually breathtaking.

Jonathan and crew arrived when they said they would, did the work quickly, and handled all my questions and concerns. The new steps, landing and walkway look great. Their cleanup was thorough. I’m entirely impressed, and will bring them back for garage floor work. Thank you !
We hired Coliseum Concrete to replace our garage floor, driveway, front step, pathway and the backyard patio. Jonathan and his crew were excellent and worked diligently everyday and the projects were finished on time as Jonathan promised that they would.
We used Coliseum to take out the grass in the front yard and put interlock to extend our driveway. The quality of service was exceptional and on time. They took the time to do create a good plan beyond our satisfaction and also made recommendations to add better aesthetics to our plan
We had an excellent experience with Jonathan and his team. They transformed our under deck area into a fully usable space. The team worked hard for the three days they were on-site. The workmanship was exactly what you would hope for a large job as ours (650 sq ft). The last day they multitasked and sealed the concrete while others were cleaning up and putting down all new soil. I am extremely happy with the end product and would recommend them to anyway.

Frequently Asked Questions: Interlock Driveways in Ottawa
Can you perfectly match an extension to my existing driveway?
Yes. While stone colors can shift slightly by “lot,” we use our extensive supplier network in Ottawa to find the closest possible match in texture and tone. We also specialize in creating contrasting borders that make the extension look like a deliberate, high-end design feature.
Is interlock strong enough to hold my heavy SUV or truck?
Absolutely. The strength of an interlock driveway comes from the compacted base layers and the interlocking action of the stones. We use 80mm thick pavers specifically designed for vehicular traffic, ensuring your driveway can handle heavy daily use without cracking or sinking.
Why is interlock a better choice than asphalt for Ottawa homes?
Interlock is a modular system, meaning it is flexible. Unlike asphalt or solid concrete, it can move slightly with the frost heave and return to its original position. Additionally, if a stone is ever stained or a utility line needs repair, we can replace individual stones without having to tear up the entire driveway.
How do you prevent weeds from growing in the cracks?
We use polymeric sand in every joint. Once swept in and misted with water, this sand hardens to create a durable seal that is specifically designed to resist weed growth and prevent ants from tunneling, keeping your driveway looking clean and pristine.
Does an interlock driveway require a lot of maintenance?
Interlock is remarkably low-maintenance. We recommend a professional cleaning and resealing every 3–5 years to keep the colors vibrant and the jointing sand intact. Regular sweeping and an occasional rinse are usually all that’s needed to maintain its luxury appearance.
