Every day, some 85,000 vehicles cross the 13.5 km long, six-lane cable-stayed bridge linking Penang Island to the Malaysian mainland. Following an accidental
fire in 2010, the structure was in urgent need of restoration and repair, as well as additional strengthening. Sika® CarboDur® system with its highstrength
carbon-fiber reinforced polymer plates allowed this vital artery to be properly strengthened within two short months without any traffic closures.

Fit for Use - Bridge Rehabilitiation with Sika® CarboDur®

Rehabilitation of the first Penang Bridge required a strengthening system that was able to compensate for the lost flexural strength and restore structural safety. As the bridge could not be closed to traffic, the strengthening materials had to be transported by boat to scaffolding temporarily suspended below the carriageway. The ultra-lightweight, high-strength carbon- fiber plates from the Sika® CarboDur® range offered the ideal structural strengthening solution. The damaged concrete was first repaired with the SikaTop® and SikaGrout® products. The affected 40 m-long prestressed-concrete girders were then reinforced by permanently bonded Sika® CarboDur® plates using Sikadur® epoxy adhesive. Within two short months, 4,200 m of Sika® Carbodur® plates were in place to provide the required strengthening and the Penang Bridge was once again fit to accept traffic loads.

Sika Technologies for Southeast Asia's Longest Bridge

Sika technologies have been used in the construction of many of the world’s tallest buildings, longest tunnels and most spectacular bridges. The roll call also includes the longest bridge in Southeast Asia, inaugurated on March 1, 2014 after a seven year construction period. The second Penang Bridge has a total
length of 24 km, with 17 km spanning across the sea at a height of up to 30 m. It was built as a second crossing to the island to relieve the existing bridge link’s heavy traffic demands. Sika technologies contribute to the state of art earthquake resistance and an expected service life of 120 years.
