Stand D34
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, PatchGuard and ProtectorJoint 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.
Founded in 2005 CPT has gone from strength to strength, consistently delivering cost effective, innovative and practical solutions. Our Directors have over 40 years of combined experience in concrete repair consultancy and over 30 years of experience in the electro-chemical treatment of reinforced concrete structures. We have produced over 100 technical papers, many of which are available to download from our website (www.cp-tech.co.uk) and have frequently collaborated with Loughborough and Nottingham Universities on corrosion related research projects. Our knowledgeable sales, production, and R&D teams, and distributor partners, are all dedicated to ensuring customer satisfaction and delivering high quality, industry leading products. We have cathodic protection technicians and engineers trained to BS EN 15257 levels 1,2 and 3 for site support, supervision and design. From our UK base we develop and manufacture cutting edge corrosion control solutions for a wide range of structures including bridges , car parks, jetties and concrete framed buildings. Our unique, compact and powerful sacrificial and hybrid anodesTM have been installed on over 700 projects worldwide, including in Australia, the USA, Japan and the UAE. With research and development at the core of the company we are constantly developing our product range, enabling us to remain at the forefront of corrosion control technology. A typical example is our ProtectorJoint anode which has been designed for protecting the difficult to access steel in bridge half joints. If you manage or own a structure suffering from corrosion related cracking and spalling we invite you to contact us. Our corrosion experts are on hand to assist you with concrete testing, specification preparation and supply of corrosion control materials.

DuoGuard Hybrid Anode
DuoGuard™ Hybrid Anode
Stops corrosion and extends structural life.
2nd generation targeted protection
20 – 50 years protection
Benefit of both impressed current and galvanic cathodic protection, no permanent power source required
Manufactured in the UK to ISO9001
Our unique DuoGuard™ range of discrete anodes features innovative dual technology to arrest steel reinforcement corrosion within 7 days. DuoGuard™ is installed into concrete structures to stop reinforcing steel corrosion caused by chloride salts and carbonation. It can be used to protect contaminated but unspalled concrete saving the time and cost of replacing the concrete material. With a long system lifetime the DuoGuard™ anode provides a cost effective, maintenance free method of corrosion protection.

PatchGuard sacrificial anode
PatchGuard™ Galvanic Anode
Extends the life of contaminated reinforced concrete.
2nd generation targeted protection
Up to 20 years protection
Galvanic protection for areas of reinforced concrete at risk of corrosion damage
Manufactured in the UK to ISO9001
Highways England specification clause 5712 Type1b compliant
Our PatchGuard™ galvanic anodes redress the electrochemical imbalance induced through removal of contaminated concrete in patch repairs, commonly known as the Incipient Anode Effect. PatchGuard™ anodes corrode preferentially to the surrounding steel – protecting it from further corrosion damage.

PatchGuard Connect sacrificial anode
PatchGuard™ Connect Galvanic Anodes
Extends the life of contaminated reinforced concrete.
2nd generation targeted protection
Up to 20 years protection
Galvanic protection for areas of reinforced concrete at risk of corrosion damage
Manufactured in the UK to ISO9001
Our PatchGuard™ Connect galvanic anodes corrode preferentially to the surrounding steel – protecting it from further corrosion damage.

ProtectorJoint anode (for half joints)
ProtectorJoint™ Galvanic Anode
Our unique ProtectorJoint™ system is designed to be installed into existing joints or gaps between structural elements, delivering powerful long-term corrosion protection to adjacent steel reinforcement.
Non-invasive rebar corrosion control technology
Targets hidden defects deep within structural elements
Up to 20 years protection
Manufactured in the UK to ISO9001

PatchGuard™ Strip Galvanic Anodes
PatchGuard™ Strip Galvanic Anodes
PatchGuard™ Strip can be installed into slots in the concrete cover zone, or into bedding joints, and is ideal for the protection of embedded steel beams or congested areas of reinforcement.
Targeted corrosion protection
Compact size to fit in 6mm (1/4”) wide slots
Quick and easy to install
No need to break out contaminated concrete
Measurable performance
Up to 20 years protection

RebaGuard sacrificial anode
RebaGuard™ Galvanic Anode
RebaGuard™ is a discrete anode for new build and repair applications.
Fixes directly to steel reinforcement
Located within patch repairs or new in-situ concrete
Combats the incipient anode/ring anode effect
MCHW specification clause 5712 Type 1a compliant
Integral corrosion resistant tie wires
No long-term maintenance
Rapid installation
Suitable for all rebar sizes
