CPT designs and manufactures leading edge corrosion solutions for reinforced concrete structures. Our unique, compact and powerful PatchGuard and DuoGuard anodes have been installed on over 500 projects worldwide. CPT innovations, protected by multiple patents, have been subject to comprehensive independent evaluation with over a decade of proven performance.
Concrete Preservation Technologies Limited researches and develops new technologies for the assessment, treatment and monitoring of reinforced concrete structures.
The CPT directors have over 60 years combined experience in concrete repair consultancy and electrochemical corrosion treatments. With innovation at the core of the company, we are constantly developing new products to ensure we remain at the forefront of corrosion mitigation technology.
Our powerful DuoGuard hybrid system is cutting edge technology and stops reinforcing steel corrosion caused by chloride contamination and carbonation for periods in excess of 25 years. By requiring no permanent power source, or expensive control equipment, the system delivers long term reliability and major life-cost benefits.
PatchGuard is a next generation discrete sacrificial anode applied as an integral part of the patch repair process in chloride contaminated concrete. The unique design of PatchGuard, whereby the anodes are positioned in the contaminated concrete around patch repairs, results in a greatly improved performance compared to traditional sacrificial anodes.
CPT works closely with clients to assess corrosion affected structures and to design bespoke solutions that will significantly extend asset life.
