Concrete can be damaged in a variety of ways. Perhaps you have a concrete structure that has suffered damage from a heavy impact, or maybe your structure is leaching water or has experienced some other chemical exposure.
If you are dealing with reinforced concrete then perhaps it is not the concrete itself that caused the problem but the corroding steel resulting within is causing cracking and spalling.
Whatever the cause of your concrete problem you will need to arrange for concrete repair to take place before the situation deteriorates to a position where the concrete structure can no longer be saved. Here are four of the most popular methods of concrete repair that can be undertaken. Your individual circumstances and the nature of the damage will determine which is the most appropriate concrete repair solution in your case.
Steel Reinforcement Primers
Concrete repairs using steel reinforcement primers are intended to offer additional protection and to function as a barrier that stops further penetration by water and consequent corrosion of the steel. The steel reinforcement primer is applied once the exposed steel reinforcement has been subject to mechanical blast-cleaning and the damaged concrete and contaminants have been removed.
If you want to increase the bond or adhesion of a concrete repair mortar that will be applied later then a bonding bridge is a great choice. These bridges can be used to fill troughs in your concrete substrate and improve the wetting of a profiled surface. While these bridges cannot usually be used on their own, they are a useful part of a larger concrete repair system.
Concrete Repair Mortars
Concrete repair mortars come in a variety of types including hand applied mortar, machine sprayed mortars, and poured concrete repair mortars. These may be pre-batched cement based mortars or they could be applied by trowels or gloved hands so that they align with the existing profile of the concrete. They are typically used for patch repairs or repairing concrete spalling where local corroding reinforcement is needed, and will need to be carefully chosen to match with the nature of your structure and the damage it has experienced.
Levelling mortars are often used once localised concrete patch repairs have been completed on the concrete structure. They serve to fill and level any remaining defects which would otherwise allow the entrance of water and other gases or liquids into the concrete. They can also be used to provide additional surface cover to ensure that the surface of the concrete is entirely uniform.
Whatever damage you want to repair you will need to discuss the situation with someone with the appropriate concrete repair experience who will be able to direct you to the most appropriate solution.
