BITUMELIT PR 5 is designed for waterproofing of reinforced concrete slab of carriage way on bridge constructions and other trafficked areas. Can be also used as single-layer waterproofing of the foundation.

BITUMELIT PR 5 polyester reinforced membranes are applied by traditional Torch – On methods onto previously prepared surface, clear of any debris or sharp projections, primers shall be used to prepare substrate for achieving most effective waterproofing longevity. The membranes should be heated carefully ensuring the complete melt of dispersible film as work proceeds. Side laps must be minimum 75mm with end laps at minimum of 100 mm. The subsequent cap sheet layer should be offset 300 mm from the underlay to avoid build up of overlaps.
