Cathodic protection is concrete repair technique that uses electrochemical currents to prevent the corrosion of concrete. The purpose of cathodic protection is to prevent the process of corrosion by converting all of the anodic (active) sites on a metal surface of a building to cathodic (passive) sites by supplying an electrical current from an alternate source. Cathodic protection is an effective measure to adopt in instances where owners are looking for a long term solution to their corrosion related issues.
Crack Injection – Concrete Repair
Cracking within concrete is caused by a number of different factors including shrinkage during curing, thermal shock and the installation of inappropriate construction joints. Crack injection is a preventative building repair technique that can be used to moderate the structural discrepancies that cracking can have.
Crack injection is widely regarded as a superior method of building repairs due to the affordable and timely nature of the work. Crack injection is the process whereby a structural binging agent, such as low viscosity epoxy resin, is injected into a crack present within a concrete unit. The injection of the resin prevents the penetration of moisture into the cracks of the concrete element, therefore improving the durability and structural integrity of the element. Such a technique is primarily used when cracks compromise the strength and reliability of an asset.
