Upgrade your home's most hardworking spaces with high-performance flooring solutions. At Coliseum Concrete & Interlock Services, we specialize in pouring and finishing garage and basement floors that are built to handle heavy vehicles, equipment loads, and constant foot traffic. We understand that these surfaces need to be more than just flat; they need to be resilient, moisture-resistant, and easy to maintain.
Our process focuses on precision leveling and superior surface density to ensure a dust-free, polished finish that enhances the cleanliness of your utility spaces. For Ottawa homeowners dealing with high water tables or heavy winter slush, we prioritize proper vapor barriers and strategic drainage slopes. Whether you are finishing a basement for living space or turning your garage into a professional-grade workshop, we deliver a rock-solid foundation that stands up to the toughest conditions.
Our garage slabs are engineered with reinforced concrete and rebar grids to support heavy vehicles, lifts, and workshop equipment without cracking.
Premium vapor barriers and strategic drainage slopes protect against Ottawa's high water tables, keeping your basement dry year-round.
Our power-troweled surfaces create a dense, sealed top layer that eliminates concrete dust and makes sweeping or mopping effortless.
Every floor is laser-leveled for a perfectly flat surface, ready for epoxy coatings, luxury vinyl tile, or left as a clean finished concrete look.

We use high-strength concrete mixes reinforced with rebar or fiber mesh depending on the application. By calculating the correct load-bearing capacity and installing precision control joints, we ensure your garage floor can support heavy SUVs and trucks without structural failure.
Yes. Depending on the condition of the existing slab, we can perform structural repairs or pour a new concrete topping. Our goal is to create a perfectly level surface that is ready for final flooring (like luxury vinyl or tile) or left as a clean, finished concrete look.
Moisture protection is our priority. We install heavy-duty vapor barriers beneath the concrete to block ground moisture from seeping through the slab. This keeps your basement drier and warmer, preventing the "musty" smell often found in older Ottawa homes.
A smooth trowel finish is popular for its sleek look and ease of sweeping, while a light broom finish provides extra traction when tires are wet or icy. We can also prepare the surface for epoxy coatings if you're looking for a high-gloss, chemical-resistant showroom finish.
Most modern Ottawa basements require a sump pit or a floor drain to manage potential water ingress. During the pour, we expertly pitch the floor toward the drainage point to ensure that in the event of a leak, water moves away from your walls and toward the exit, protecting your finished space.
