Concrete stairs are a durable and functional feature for many homes and businesses in Kamloops. However, like all things, they don’t last forever. Over time, exposure to the elements—particularly our region’s freeze-thaw cycles and hot summers—can take a toll on even the sturdiest concrete structures. Knowing when to repair or replace your concrete stairs is important for maintaining safety and aesthetics. At Hardaker Concrete, we’re here to help you make the right decision.
When to Consider Repairing Your Concrete Stairs
In many cases, repairing your concrete stairs is a viable and more cost-effective option. Here are some common scenarios where repairs can be the best solution:
1. Minor Cracks
Concrete naturally expands and contracts with changes in temperature, which can lead to small, hairline cracks over time. These cracks are typically less than 0.5 cm (¼ inch) wide and aren’t deep enough to affect the structure’s integrity. If your stairs show signs of minor cracking, there’s no need to panic. A concrete filler or sealer can easily restore their appearance and prevent further damage.
2. Surface Wear
Kamloops’ climate can be tough on concrete surfaces, leading to wear over time. If the surface of your stairs is starting to erode or become rough but the underlying structure is still sound, resurfacing is a great option. Resurfacing involves grinding / chipping off the old surface that’s starting to fail. Then applying a new layer of concrete to restore the textured finish and improve traction, extending the life of your stairs.
3. Chips and Spalling
Spalling, or flaking, occurs when small pieces of concrete start to chip away. This is often caused by water penetrating the concrete and freezing, which expands and breaks apart the surface. If spalling is limited to small areas, repairing these spots with a patching compound can prevent the problem from spreading and save you from a more extensive repair later on. A coat of sealer will help repel water from the smaller cracks and reduce salt damage.
4. Discolouration
Concrete stairs can become discoloured due to exposure to the elements, foot traffic, or spills. While discolouration doesn’t necessarily impact the function of your stairs, it can detract from their appearance. Often, a thorough pressure washing can bring things back to their original shine.
When to Consider Replacing Your Concrete Stairs
While repairs are often sufficient, there are situations where replacement is the best—or even the only—option. Here are some signs that it might be time to replace your concrete stairs:
1. Large Cracks
If the cracks in your stairs are wider than 0.5 cm (¼ inch) or extend deep into the structure, they could indicate a serious problem. Large cracks can compromise the stability of your stairs, making them unsafe. If these cracks are growing or affecting the entire structure, it’s likely time to consider replacing the stairs altogether.
2. Uneven or Sunken Stairs
If you notice that one or more steps have shifted, sunk, or become uneven, this could be due to soil movement or improper installation. Uneven stairs are a major safety hazard and can be difficult to repair effectively. In many cases, replacement is the best option to ensure that your stairs are safe and properly aligned.
3. Extensive Spalling or Erosion
If spalling has affected large sections of your stairs or the concrete is severely eroded, the damage may be too extensive for a simple repair. In this case, replacing the stairs may be more cost-effective in the long run. New concrete will provide a fresh, durable surface that will stand up to Kamloops’ challenging weather conditions.
4. Structural Instability
If your stairs are wobbling, tilting, or showing signs of significant structural weakness, it’s time for a replacement. Structural instability is not something that can be easily fixed with a patch or resurfacing. Replacing the stairs will ensure that they are safe and stable for years to come.
5. Damage to the Foundation
Sometimes, the damage to your stairs extends beyond the surface and affects the foundation. In these cases, simply repairing the surface won’t address the underlying issues. If the foundation is compromised, replacing the stairs is necessary to prevent further damage and ensure safety.
Pouring New Concrete Over Old Stairs: Is It an Effective Solution?
One question we often get at Hardaker Concrete is whether pouring new concrete over old stairs is a viable solution. The answer depends on the condition of the existing stairs.
When It Works
If your stairs are structurally sound but have minor surface issues, such as shallow cracks or slight erosion, pouring a new layer of concrete over the old surface can be an effective solution. This process, known as resurfacing, can restore the appearance of your stairs and provide a fresh, textured surface. This can be a great option for commercial properties where closing down the entire entrance to a building for an extended period of time is impractical.
When It Doesn’t
However, if your stairs have significant structural issues, such as large cracks, uneven settling, or instability, resurfacing isn’t enough. The new concrete won’t address the underlying problems, and the damage will likely reappear. In these cases, replacing the stairs is a better option.
It’s also important to consider that proper preparation is essential for resurfacing to be successful. The old concrete must be clean, stable, and free of loose material. If the new concrete doesn’t adhere properly, the overlay can fail, leading to further issues.
