Concrete repairs are important to prevent further damage and extend the lifespan of concrete structures. Whether it’s a cracked driveway, pool deck or industrial floor, concrete repair needs to be performed properly for the repair to last.

Otherwise, the repaired crack is likely to recur and require further repairs.
To ensure that your repairs will stand the test of time, follow these tips from experts in concrete repair:
Investigation of the cause of the cracking and deterioration is crucial to ensure lasting quality. The investigation can involve destructive testing or just a few simple tools such as a hammer and spray paint. Ping the surface of the concrete for a sound; delaminated areas will have a hollow sound as opposed to the hard ring of sound concrete.
A key factor click here that impacts long term durability is the bond strength of the repair material with existing concrete. This can be impacted by many factors including the physical properties of the repair material, application methods, surface preparation, curing practices and inspection.
Concrete repair materials are designed to match the situation and structural requirements of a structure. QUIKRETE offers concrete repair products ranging from waterproofing products to heavy-duty, fast-setting, commercial-grade and even sculptable products that a contractor can shape in place.
The location of a concrete repair is another important consideration. Some sites restrict the type of equipment that can be used and may not allow odorous or toxic repair materials. Others are highly trafficked and need fast-setting materials that will minimize downtime.
If you are repairing a concrete crack, widening the crack by routing and sealing is an option that can provide long-lasting results. This can be effective for both active and dormant cracks and is a quick, cost-effective method. Prior to sealing, clean the area thoroughly and sand the crack edges to remove any loose or spalling concrete. This will help the sealant adhere to the concrete and extend its life.
For narrow cracks, you can use a backer rod to create a base for the repair material. Choose a rod diameter that is larger than the width of the crack and stuff it into the crack, following the product manufacturer’s instructions. Then fill the crack with your choice of repair material.
