REFURBISHMENT OF THE WATERPROOFING ON LOOSE TIMBER BOARDS WITH JOINTS BETWEEN THE LOWER BOARDS AT 5 mm with self-adhesive membranes on ROLLBASE.
Refurbishment of old loose timber boards with joints between the lower boards at 5 mm, with self-adhesive membranes on ROLLBASE.
After having restored the surface flatness of the timber boards and before laying the self-adhesive membranes, ROLLBASE HOLLAND POLIESTERE will be mechanically fixed, with nails provided with 50 mm diameter washers, in order to regularise the surface. It is a membrane reinforced with Spunbond non-woven polyester fabrics with the bottom surface combined with a bare polyester non-woven fabric and the top surface coated with a melted polymeric skin compatible with cold laying of self-adhesive membranes. Subsequently, on the entire surface, a self-adhesive membrane, self-protected with slate granules MINERAL SELFTENE HE OVERLAPS or MINERAL DESIGN AUTOADESIVO EP OVERLAPS, will be installed in complete adherence by simple pressure at room temperature.
