Being a professional concrete contractor, we understand that concrete is one of the most durable and reliable materials for construction and has relatively low-maintenance cost. However, concrete is not immune to problems, and over time, it may develop issues that require repair. As a leading concreters in Newcastle, we have seen and fixed a range of concrete problems over the years. Even the best quality concrete can experience problems if it is not installed or maintained correctly. Here are some of the most common concrete problems we encounter and their fixes:
Cracks:
Cracks are the most common problem with concrete. They can occur due to various reasons, such as improper mix proportions, insufficient curing, or improper placement of reinforcement. Cracks can be either structural or non-structural, and it’s essential to determine the type of crack before deciding on a fix. If the crack is shallow and not very wide, you can fix it by filling it with epoxy or polymer-based fillers. However, if the crack is deep or structural, you will need to consult with a professional concrete contractor to repair it. A structural crack may require the removal of the entire section of concrete and replacement with new concrete.
- Scaling: Scaling is another common concrete problem that can occur due to exposure to extreme temperatures or freeze-thaw cycles. Scaling can cause the surface layer of the concrete to peel off, leaving a rough and uneven surface. To fix scaling, you need to remove the loose concrete surface and apply a surface treatment or sealer to protect it from further damage. It is essential to fix scaling as soon as possible to prevent water from penetrating the surface and causing additional damage.
- Spalling: Spalling is similar to scaling, but it occurs deeper in the concrete, usually due to poor installation or poor mix design. Spalling can cause the concrete to break down and become uneven. To fix spalling, you need to remove the damaged concrete and apply a repair mortar or grout. It’s crucial to fix spalling promptly to prevent water from penetrating the surface and causing additional damage.
- Discoloration: Concrete discoloration can occur due to various reasons, such as exposure to sunlight, chemical reactions, or poor curing. Discoloration can be fixed by using a surface treatment or applying a stain to the surface to give it a uniform color. It is essential to determine the cause of the discoloration before applying a fix to prevent it from happening again in the future.
- Curling: Curling is a common problem that occurs due to temperature differences between the top and bottom of the concrete slab. Curling can cause the slab to lift or become uneven. To fix curling, you need to use a curling control joint or a dowel to allow for movement. It’s crucial to install control joints during the concrete installation process to prevent curling from occurring in the future.
- Settlement: Settlement occurs when the soil beneath the concrete slab sinks or settles, causing the slab to sink and become uneven. Settlement can be fixed by using polyurethane foam injections to lift the slab and stabilize it. It’s crucial to address settlement promptly to prevent the slab from becoming a tripping hazard.
- Deterioration: Deterioration is a common problem that occurs due to exposure to harsh weather conditions or chemical exposure. Deterioration can cause the concrete to become weak and crumble. To fix deterioration, you need to remove the damaged concrete and replace it with new concrete. It’s essential to address deterioration promptly to prevent the damage from spreading.
- Moisture: Moisture can be a problem for concrete, especially in areas with high humidity or moisture levels. Moisture can cause the concrete to become slippery and unsafe. To fix moisture problems, you need to use a surface treatment or apply a slip-resistant coating to the surface. It’s crucial to address moisture problems promptly to prevent accidents and injuries.
In summary, concrete problems are common, but they can be fixed with the right approach and expertise. We, as experienced concreters, know that concrete problems can arise due to various reasons. However, with proper installation, maintenance, and repair techniques, they can be fixed effectively. It’s essential to address concrete problems promptly to prevent them from becoming bigger and more expensive issues. If you are experiencing any concrete problems, it is best to consult with a professional concrete contractor to determine the root cause of the problem and develop an appropriate solution before it’s late.
