Concrete Preservation Technologies Limited

Stand E05
At CPT we are proud to design and manufacture cutting edge corrosion control solutions for reinforced concrete structures and masonry encased steel framed buildings. From our UK base we manufacture and distribute our unique DuoGuard and PatchGuard systems worldwide. If you manage or own a structure suffering from corrosion related cracking and spalling we would be delighted to hear from you. Our corrosion experts are on hand to assist you with concrete testing, specification preparation and supply of corrosion control materials. Our aim is always to extend structural life and minimise maintenance costs.

Living with RAAC: Expert answers Frequently asked Questions
Our unique RAAC-Guard™ range of hybrid anodes has been developed in partnership with the NHS. RAAC-Guard™ is installed into RAAC panels or onto the surface of RAAC planks and will stop reinforcing steel corrosion in as little as 7 days. The use of RAAC-Guard™ can save the time and cost of replacing the autoclaved aerated concrete (AAC) where it is still structurally sound. With a long system lifetime, RAAC-Guard™ provides a cost effective, maintenance free method of corrosion protection.
Duoguard FINAL
DuoGuard™ anodes feature new generation electro-chemical technology to stop reinforcing steel corrosion caused by chloride salts and carbonation for up to 50 years. The full package: CPT also supplies all the ancillary materials needed for DuoGuard™ installation, including wires, connectors and embedding mortar.
Patchguard FINAL
PatchGuard™ counters corrosion adjacent to the patch following patch repair but unlike traditional sacrificial anodes it is installed at the perimeter of the patch repair into the parent concrete. This significantly improves the ionic current flow from the anode through the concrete material as the parent concrete is less resistive compared to repair mortars, making the PatchGuard™ anode more efficient than traditional sacrificial anodes. The full package: CPT also supplies all the ancillary materials needed for PatchGuard™ installation, including embedding mortar and attachment materials.
