Concrete Preservation Our Products for preventing steel corrosion in concrete structures
The function of our products is to preserve the operational life of steel reinforced concrete structures by stopping corrosion and protecting vulnerable parts of a structure from possible attack of chloride salts and carbonation. Our products do not require long term maintenance costs, the performance of our products can be monitored and all sales come automatically with free consultation and corrosion evaluation from our experts.
Duoguard 500
Duoguard 500 is installed into concrete structures to stop reinforcing steel corrosion caused by chloride salts and carbon dioxide. With a lifetime capacity of up to 50 years, Duoguard 500 provides a cost effective, measurable method of corrosion protection. Over 20000 units have been applied to bridges, car parks, coastal and industrial structures.
Rebaguard
Rebaguard is a discrete sacrificial anode applied as a remedial measure to patch repairs to reinforced concrete structures suffering attack from chloride salts. Rebaguard counters corrosion adjacent to the patch following patch repair. The Rebaguard anode installation can be monitored using half-cell potential surveys, current outputs and reinforced steel corrosion rate measurements.
Monitoring Systems
CPT supply bespoke monitoring systems for continual physical assessment of reinforced concrete and steel frame structures. Monitoring systems can be simple single input to multiple input remote controlled logging systems. Physical parameters commonly monitored include steel potential, steel corrosion rate, galvanic current output, crack movement and temperature. Monitoring system can form a part of life care plan strategy.
MN15 Reference Electrode
The MN15 reference electrode is a manganese oxide based probe used to monitor steel potentials to give an indication of the steel environment. MN15 offers benefits versus traditional reference cells installed into concrete in terms of increased contact surface area and excellent polarisation characteristics.
Reinforced Concrete Corrosion Protection
Although the vast majority of reinforced concrete structures generally perform well, exposure to certain aggressive environments can result in rapid deterioration and ultimately in failure.
Primarily steel corrosion results from attack by chloride salts or atmospheric CO2 which, having penetrated the surface cover concrete, break down the protective oxide coating on the surface of steel reinforcing bar. The resulting corrosion products are very expansive and often result in spalling of the concrete surface. It is important that any potential failure mode is identified early and dealt with so as to preserve the operational life of the structure.
