Concrete floors are common in industrial and commercial facilities because of their hardened surface and durability, but they can be damaged by a variety of factors. Oftentimes, the damage is due to temperature changes or heavy weights being dropped on the floor. Concrete floor repair contractors can fix holes, cracks and spalling, as well as resurfacing the concrete to make it look better.Resource : concrete-repair.co.uk
Sinking Floor
If a garage floor begins to sink in certain areas, this can be a sign of a failing support beam or joist. A professional can perform a free assessment to determine what needs to be done to correct the issue. This may include adding supplementary supports under the floor joists or replacing the existing ones.
Spalling
Over time, small freeze-thaw water damages the surface of the concrete and causes it to chip away in a process called spalling. This can be caused by a number of factors, such as poor concrete mix or finishing, corrosive road salts that eat through the concrete or deicing fluids that lower the freezing temperature of water in the concrete. Fortunately, there are several concrete repair products that can be used to fill these pitting and spalling spots in the concrete or to resurface it.
When using these types of products, it is important to follow the instructions closely. Many of these repair materials require that the concrete be prepared properly to ensure a strong and long-lasting bond. You will also need to consider the dimensional characteristics of the product, as drying shrinkage can easily debond a repair.
