Bridges and tunnels must be regularly inspected and kept in a safe and serviceable condition to protect users and preserve structural life. Bridges and tunnels with exposed reinforced concrete elements are vulnerable to corrosion, often initiated by de-icing salt ingress through defective joints or low concrete cover. If corrosion induced spalling results in debris falling onto highways or railway tracks then disruption can be significant. When it comes to accessing the structure to repair the damage, costs can escalate and track or lane closures can cause severe delays to travellers.
CPT corrosion control systems offer long term maintenance free protection, eliminating the need for repeat repair works with associated high access costs. Our unique technology, which is fully compliant with international standards, accurately targets hot spots of corrosion, from bearing shelf to beam and from column to deck soffit, extending structural life and minimising life costs.
CPT has extensive experience of providing both the private and public sectors with bespoke corrosion management solutions for bridges and tunnels. From testing and assessment works to solution design, CPT can help you every step of the way.
