Concrete kerbs are durable and can withstand adverse conditions. However, these structures will not last forever or resist all damage. For instance, kerbs are vulnerable to cracking over time. The causes of cracking differ. In some cases, poor maintenance practices lead to moisture ingress and the formation of fissures due to the freeze-thaw cycle. Also, constant impact from vehicles or lawnmowers might cause some damage to the kerbing. In other cases, the cracks occur due to poor installation. Regardless of the underlying problem, here are essential tips to keep in mind for kerb repairs.
Consider Kerb Replacement
If your kerb is extensively damaged, think about the benefits of replacing the structure instead of conducting simple repairs. This approach is ideal if the kerbing has numerous cracks at frequent intervals. Patching up this type of damage will result in an unattractive structure. Moreover, extensive cracking indicates structural problems, so the localised repair will not solve the weakness. The issues could lead to recurrent damage. If you decide to replace the kerbing, plan for demolishing and consult a qualified concrete contractor for the new construction.
Clean the Kerb Crack
If the damage to your kerbing is minor and localised, the repair process will be relatively simple. Begin the work by cleaning the area for the restorative project. Remove debris around the kerb and pluck out weeds emerging from cracks. Wweep the area thoroughly to eliminate foreign materials. Once the area is clean, prepare the cracks for patching. This process involves removing the damaged concrete residue from the cracks.
The old material along the cracks will not promote the adherence of a patching compound. Therefore, the exposed concrete must be removed for long-lasting repair. Use a chisel to break away the material along the cracks. Ideally, you should expose a clean and uncompromised surface. Also, eliminate stubborn bumps by using a wire brush or heavy-duty steel wool. Additionally, wash the kerbing with clean water and allow time to dry.
Apply Patching Material
Finally, the cleaned crack needs an appropriate patching compound to fill and seal the damage. Commercial patching products are available at hardware and building material stores. Purchase a good product and prepare it as recommended by the manufacturer. Fill the crack with the resulting mix using a trowel. Carefully layer the concrete material and pack the crack completely to create a stable repair. When the crack is filled, scrape off the residue on the restored section. Make sure to match the surface to the rest of the kerbing.Share
