Concrete repairs describe all the different methods used to restore and maintain concrete buildings whenever they suffer damages. If unattended to, even the simplest damages like cracks and worn concrete could substantially degrade their structural integrity. Thanks to all different concrete repair methods carried out by skilled and experienced tradesmen, you can restore a building to its original beauty, while at the same time strengthening it and making it more durable. Here are some of the common types of concrete repairs you can come across.

Concrete restoration

Concrete surfaces have to consistently withstand different elements like harsh weather, chemicals or impact, which eventually leads to degradation of the surfaces. These repairs often have to be carried out on slabs and concrete floors that have suffered general wear or impact damage. Major repair work involves removal of damaged parts of concrete using either small handheld pneumatic tools, electric tools or through hydro-demolition equipment when dealing with the heavy jobs. Once the damaged concrete has been removed, a primer is applied and a fresh mortar reapplied to the exposed surfaces. Ensuring the new mortar ends up with the same finish as the original concrete. It takes lots of skill and experience. Restoring damaged concrete can help reinstate the load bearing capacity of a building as well as restoring its original aesthetics.

Resin Injection

Resin injections are used to seal small cracks in concrete, especially when the cracks are too small to apply mortar. Resins used to seal cracks and voids in concrete structures help to stop the cracking in its early stage, offering you an effective way of preventing further degradation of your concrete structure. The type of resin used in concrete repair is very strong, actually stronger, quicker drying and much easier to implement than mortar. Injections of resins provide a more convenient and quicker way to deal with cracks and minor defects in concrete. Resins are available in different viscosity levels selected depending on the size of the crack. Low viscosity resins are suitable for the small cracks.

Corrosion control

Different protective coatings help prevent corrosion and enhance the durability of concrete surfaces. Corrosion control reduces damage, which leads to reduced maintenance costs in the long run. Several corrosion techniques are available today ranging from application of corrosion inhibitors, application of barrier coatings, to galvanic cathodic protection systems. You can apply a protective coating on concrete after repair; the coating helps prevent against corrosion and rusting of supporting metal framework.
