Concrete Preservation Technologies offers corrosion repair and protection for reinforced concrete structures
We are constantly researching and developing new technologies for the treatment and assessment of reinforced concrete structures. Our latest inovation, PatchGuard™, is a galvanic anode for protecting steel located within the parent concrete following patch repairs, whereas the unique DuoGuard™ Hybrid Anode™ offers a low-maintenance cost-effective solution for targetted areas or whole structures.
CPT supplies everything you need to install our products* and helps clients to develop a comprehensive understanding of the condition of their structure by surveying, testing and monitoring. We understand that the overall quality of our service is paramount to our customers and thus we are here to advise and guide at every stage of the project, giving our clients a cost-effective concrete remediation solution which can form part of a structure life care plan.
The new sacrificial anode system for the galvanic protection of unrepaired areas of concrete which are at risk from corrosion damage. PatchGuard Connect anode system can be powered at any time in the future if this is considered at the design stage.
PatchGuard™ galvanic anode is located within the parent concrete. Protective current is delivered directly to the steel outside the patch which is at greater corrosion risk as opposed to clean steel within the patch repair. The unique anode design permits use of high resistivity repair material and bonding primers.
DuoGuard™ hybrid anode™ system halts steel corrosion within seven days. The application of the 7 day high current density treatment has the effect of halting corrosion activity on the reinforcing steel surface. This is achieved by moving corrosion to the installed anodes whilst changing the environment at the steel to passive conditions.
Our Monitoring Systems can be installed on a stand-alone basis to monitor a structure for corrosion damage or installed to monitor system performance and steel corrosion rates (potentials) following the installation of an anode system. This allows the client to be continually updated regarding the state of their structure.
