We build high-strength concrete stairs and porches designed as a permanent upgrade for your home. By combining reinforced engineering with slip-resistant finishes, we ensure your entrance remains safe and stunning through every Ottawa season.
Your front entrance is the first impression visitors have of your home. At Coliseum Concrete & Interlock Services, we specialize in building custom concrete stairs and porches that combine structural integrity with architectural elegance. Whether you need a simple set of replacement steps or a grand multi-tiered porch landing, our team delivers a finished product that is safe, durable, and visually striking.
Every set of stairs we pour is anchored with deep footings that extend below Ottawa's frost line, preventing the heaving and separation that plagues shallow installations. We use precision formwork to achieve crisp, clean edges and combine rebar reinforcement with high-strength concrete to ensure your steps can handle decades of heavy foot traffic, salt exposure, and extreme temperature swings without cracking or shifting.
Every staircase is anchored with sonotube footings below the frost line, preventing heaving, separation, and shifting through Ottawa's harsh winters.
Our textured broom finishes and non-slip sealers provide secure footing in rain, ice, and snow — keeping your family safe year-round.
Crisp, clean edges and perfectly uniform risers achieved through expert formwork and meticulous leveling on every pour.
A professionally poured entrance dramatically elevates your home's street presence and adds lasting value to your property.

This is usually caused by poor footing depth or soil erosion. In Ottawa, the frost can heave shallow stairs. We prevent this by anchoring our stairs to the foundation or using sonotube footings that reach below the frost line, ensuring your steps stay perfectly aligned for the long haul.
Absolutely. While a clean broom finish is excellent for traction, we can also design porches that incorporate interlock stone borders or prepare the surface for natural stone overlays. We can create rounded corners or multi-tiered landings to give your entrance a truly custom, high-end look.
Yes. Concrete provides a solid, non-flexible surface that doesn't become "bouncy" or rot over time. When finished with the correct texture, concrete offers superior grip in wet and icy conditions. Plus, unlike wood, it can handle the frequent use of ice melt and heavy shoveling without surface damage.
A standard set of stairs typically takes 2 to 4 days. This includes the form-work, placing the reinforcement steel, and the final pour. Because stairs require precision curing, we carefully monitor the drying process before the forms are removed to ensure a flawless, sharp edge.
We do this frequently! We specialize in seamless transitions. We can pour concrete stairs that lead directly into an interlocking stone path, ensuring the heights and colors complement each other perfectly for a cohesive landscape design.
