What CONCRETE PRESERVATION TECHNOLOGIES LTD does

Concrete Preservation Technologies Ltd (CPT) is a UK-based specialist manufacturer founded in 2005 and headquartered in Long Eaton, Nottinghamshire. The company designs, manufactures, and supplies electrochemical corrosion control systems for reinforced concrete structures, with a product portfolio centred on the DuoGuard hybrid anode (operating in both impressed current and galvanic modes for 20-50 year protection), the PatchGuard family of galvanic anodes for patch repairs, and the specialised RAAC-Guard system for Reinforced Autoclaved Aerated Concrete panels developed in partnership with the Loughborough University RAAC Research Group since 2019. Supporting products include the MN15 Manganese Oxide reference electrode for monitoring and ProtectorJoint for joint-embedded protection. Manufacturing is carried out at the ISO 9001 and ISO 14001 certified Long Eaton facility.

CPT operates a B2B enterprise sales motion targeting infrastructure owners, government bodies, and private asset managers across bridges and tunnels, multi-storey car parks, buildings (including heritage structures), industrial and marine facilities, and RAAC-affected estates. Its service offering extends beyond product supply to include CPT Surveys (testing, inspection, and electrochemical investigation), BS EN ISO 15257 Level 4 system design, ongoing remote and solar-powered monitoring subscriptions, and CPD seminars delivered at client premises. Pricing is quote-based on project specifications with multi-year contract durations aligned to the 20-50 year design life of installed systems.

Distribution is direct in the UK and Ireland and channelled through exclusive international distributor partnerships covering Saudi Arabia, Turkey, the USA, Australia/New Zealand, and Japan. The customer base is broad for a small specialist, including Network Rail, multiple NHS Foundation Trusts, Scottish Highland Council, Lancashire County Council, the Northern Ireland Assembly, EDF, Shell, National Grid, Inovyn, Maybourne Hotel Group, and Bamburgh Castle Estate. CPT has no disclosed external institutional shareholders and appears to be management/founder owned.

Core offering

Concrete Preservation Technologies designs, manufactures and supplies cathodic and galvanic corrosion protection systems for reinforced concrete structures, including bridges, car parks, buildings, industrial/marine assets and RAAC panels. Its core products are the proprietary DuoGuard hybrid anode, PatchGuard galvanic anodes, RAAC-Guard, RebaGuard, ProtectorJoint and MN15 reference electrodes, all manufactured in the UK to ISO 9001/14001 standards. The company also delivers testing, system design, monitoring and CPD training services, and distributes internationally through exclusive partners in six markets.

Product overview

Concrete Preservation Technologies designs and manufactures a portfolio of electrochemical corrosion control products for reinforced concrete structures. The core product line consists of galvanic anodes (PATCHGUARD™ family) for patch repair protection, hybrid anodes (DUOGUARD™) for dual-mode impressed current/galvanic protection, and specialized RAAC-GUARD™ for autoclaved aerated concrete. Supporting products include the MN15 Reference Electrode for monitoring and PROTECTORJOINT™ for joint cavity protection. REBAGUARD™ provides reinforcement-anchored galvanic protection. The products operate independently without requiring ongoing power supplies or complex electronic systems, providing self-powered cathodic protection that extends structural life while minimizing maintenance costs.

Products and services

• PATCHGUARD Galvanic Anode Galvanic anode installed in host concrete surrounding patch repairs, delivering protective current directly to steel at greatest corrosion risk to prevent the incipient/ring anode effect. MCHW Type 1b compliant with a design life of up to 20 years. Sold to infrastructure owners and concrete repair contractors.
• PATCHGUARD CONNECT Galvanic Anode System Interconnected galvanic anode system where anodes are wired together in series strings for broader coverage of at-risk zones in reinforced concrete structures. Sold to infrastructure owners requiring wider-area patch protection.
• PATCHGUARD STRIP Galvanic Anode Strip-format galvanic anode designed for installation into saw cuts or narrow slots in concrete cover, suitable for structures with limited access. Sold for use where conventional PatchGuard cannot be embedded.
• DUOGUARD Hybrid Anode System Interconnected hybrid anode system operating in both impressed current and galvanic/sacrificial modes. Initially powered by an external source to halt active corrosion, then self-generates galvanic current for ongoing protection, with a 20–50 year design life. Provides cathodic protection for reinforced, pre-stressed and post-tensioned concrete without breaking out sound concrete or risking hydrogen embrittlement. Sold to infrastructure owners, energy operators and heritage asset custodians.
• RAAC-GUARD Hybrid Anode System Specialised hybrid anode system for Reinforced Autoclaved Aerated Concrete (RAAC) panels, including RAAC-Guard Strip and SA variants. Realkalises the environment around reinforcement within 7 days followed by responsive galvanic corrosion protection. First-to-market solution for an asset class that previously had no dedicated remediation. Sold to NHS trusts, universities, councils and other owners of RAAC structures from 1960s–70s construction.
• REBAGUARD Galvanic Anode Individually connected galvanic anode fixed directly to steel reinforcement within patch repairs (MCHW Type 1a), delivering long-term corrosion protection compliant with Highways England specifications. Sold to concrete repair contractors and infrastructure owners.
• MN15 Reference Electrode Manganese Oxide reference electrode used to monitor steel potentials and the ongoing performance of CPT's corrosion control systems in reinforced concrete structures. Sold alongside CPT cathodic protection systems and as a stand-alone monitoring component.
• PROTECTORJOINT Galvanic Anode System Interconnected galvanic anode system designed for placement within existing expansion and construction joints to utilise joint cavities for long-term corrosion protection. Self-powered with up to 20-year design life. Sold for use on bridges, car parks and buildings with movement joints.
• CPT Surveys — Concrete Testing & Assessment Inspection, physical assessment and electrochemical investigation of steel reinforced concrete structures, including half-cell potential mapping, chloride profiling and carbonation depth analysis. Delivered to infrastructure owners, contractors and consultants as a precursor to corrosion mitigation design.
• Corrosion Mitigation System Design BS EN ISO 15257 Level 4 qualified design of cathodic protection systems, from simple sacrificial anode designs through to full ISO Standard EN12696:2022 compliant systems. Sold as a standalone design service and bundled with CPT product supply.
