Dri-Gard Protective Coating Systems were used to protect the concrete bridge structure in Gambang, Pahang. For all piers & abutments, Dri-Gard TZ 300, a solvent-free epoxy coating, was used with a dry film thickness of 200 um. For the deck soffit, RC diaphragms, capping beams & other areas, Dri-Gard CP 700, a silane-siloxane hydrophobic primer, and Dri-Gard CF 900, solvent-based MMA protective coating was used. Dri-Gard CP 700/CF 900 system has passed stringent test standards & is proven to be effective in reducing carbon dioxide diffusion, chloride ion penetration and reduction in water absorption without affecting its water vapour transmission.
