Sika helps complete bridge strengthening scheme

Sika helps complete bridge strengthening scheme

Sika CarboDur rods and Sika CarboDur plates have been used for repair works to the M3 Hawley bridge. The bridge started to show signs of excessive deflection under heavy traffic and engineers at Enterprise Mouchel devised a repair solution that included the installation of a new central bridge pier to support two existing outer piers.

To counteract changes to the deck’s dynamics and reinforce the bridge between the three structural piers, Sika CarboDur rods and Sika CarboDur plates were used – marking one of Europe’s largest applications of composite reinforcement systems.

To achieve the required performance, carbon fibre plates and rods were specified as part of a complex repair and concrete protection solution. The use of carbon fibre offered an accelerated application process and enhanced performance properties when compared to traditional steel reinforcement.

The project saw a total of 1,000mtr of Sika CarboDur Rods and 5,000mtr of Sika CarboDur Plates installed.
