Concrete will, under most circumstances provide a highly alkaline environment in which steel reinforcement will be protected from corrosion by the formation of a passive oxide layer. This passive oxide layer can in time be compromised, primarily due to the effects of carbonation or chlorides, leading to corrosion of the steel reinforcement, thus putting the long-term durability of the structure into question.

With the annual cost of corrosion to the UK economy rising to billions each year, Cathodic Protection (CP) Systems have become increasingly essential and are frequently specified as the primary solution for preserving reinforced concrete structures. CP is an electrochemical method of corrosion control that can be applied to submerged metallic materials, often utilised for the prolonged preservation of the steel reinforcement within concrete structures. Once installed and activated, CP can significantly reduce structural life cycle costs that are usually associated with traditional repair programmes.

As full members of the Corrosion Prevention Association (CPA), APA Concrete Repairs Ltd have consistently provided solutions that are unique to the needs of our clients' structures for over 17 years. Our services consist of the study, design, installation and maintenance of corrosion prevention systems for new structures, as well as the repair and protection of previously installed systems. Our engineers are certified by the Institution of Corrosion and work closely with our clients in order to design the best suited and most cost-effective corrosion prevention/cathodic protection solutions for projects of all scopes. 

APA Concrete Repairs Ltd are vastly experienced supply & installation contractors of multiple Cathodic Protection Systems and associated Corrosion Prevention Systems, including:
