We create luxury interlock driveways and functional extensions designed to boost curb appeal and provide extra parking. With our focus on superior base engineering, we ensure a level, weed-resistant surface that stands up to Ottawa's toughest winters.
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.
Interlocking stones flex with Ottawa's freeze-thaw cycles, returning to position without cracking — unlike rigid asphalt or concrete.
High-performance polymeric sand seals every joint, creating a barrier that blocks weed growth and prevents ant colonization.
Individual stones can be lifted and replaced without disturbing the rest of the surface — perfect for utility access or damage repair.
Choose from hundreds of stone styles, colors, and patterns to create a driveway that perfectly complements your home's architecture.

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.
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.
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.
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.
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.
