The resulting surface gives a strong architectural finish that looks very impressive. If the ProGRP system is properly maintained it can last as long as the building stands. ProGRP has been developed this technology further to produce the perfect all weather protection for any flat roof. It can be applied in small domestic situations right through to large industrial environments.
