Using a powered access boom, DPR recently completed the full clearing out of the main building box gutter system of Ryalux in Ossett, Wakefield. DPR were also asked to clean down and line the leaking metal gutter system, before coating the areas with a glass fibre resin compound. On another building, DPR were required to strip out a defective felt trough system and clean back the limestone chipping to then allow our professional roofers to apply a primer and polyester torch on the felt, before coating it with glass fibre resin.
