Repairing a concrete slab can be a daunting task, but with the right tools and materials, it can be done with ease. Depending on the cause of the damage, there are several methods that can be used to repair a concrete slab. Filling and bonding the tile with a high-strength epoxy is a great way to seal the crack. For large areas of damage, such as a patio, garage floor, or driveway, contractors should consider using a thin bond concrete layer.
If the surface has too many bumps for individual repairs, or if during the repair the surface suffered delamination, this method will repair the damage. In some cases, such as shrinkage cracks in thin concrete, no repair may be necessary. It is important to understand the cause of the cracks before attempting to repair them. Built on permafrost thawing or foundation problems that have displaced the slab can cause large breaks or cracks.
If you have damage to a concrete slab due to foundation problems, you'll want to address the foundation problem first. Understanding the differences between these types of concrete cracks is an important first step in diagnosing their cause and their importance to the structure. Common ways to repair a tile are to fill the surface or to inject epoxy or polyurethane. But on interior floors, or on slabs that could be subject to de-icing salts, it's important to repair the stain to prevent further damage to the tile. With the right tools and materials, you can perform durable and aesthetically pleasing repairs of common concrete surface imperfections. The only thing about shrinkage cracks in concrete is that they generally appear discontinuous.
