The existing coating had to be removed mechanically using various preparation equipment to expose the bare steel deck. Once this had been completed, we had the steel shot blasted to remove any stubborn polyurethane particles as well as rust. We then applied our rapid curing Gripmaster resin with coarse non-slip aggregate. All the expansion joints were reinstated and Robex grp tread covers installed to the stairs.
We were asked to provide a solution for works required to the bridge, which is used by students in crossing the carriageway for safe passage to the school. The bridge had been in place since the school was first built approx 15 years ago. The surface was showing major issues with corrosion that meant the existing polyurethane non-slip surface was delaminating in several areas and no longer gave a good non-slip finish.
Once preparation works were complete, our team applied the metal primer, followed by a 2mm coat of our MMA GP resin, at which time we blinded the entire surface with 0.8-1.4Mm bauxite aggregate. Following this, we applied 2 coats of our MMA sealer coat and gun applied our joint sealing material in grey.
No contract comes without a challenge. However, the greatest threat, in this case, was the great British weather, holding our guys up as the job was carried out during school shutdown and there was no way the bridge could be shut during school term. We were lucky just one day in 11 stopped us working.
A fantastic finish that should last for many years.
