PetroDPC Self-Adhesive Bitumen DPC TDS

Technical data sheet for PetroDPC self-adhesive bitumen damp-proof course rolls — 1.5 mm SBS-modified bitumen on HDPE film, 4.5", 9" and 13" widths, 15 m rolls.

PetroDPC is a self-adhesive bitumen damp-proof course membrane manufactured by Petroseal Enterprises in Lahore. Laid at plinth level and grade transitions, it forms a continuous barrier against rising capillary moisture in brick and block masonry.

Cold peel-and-stick application means no propane torch on site. Laps and junctions are overlapped by at least 100 mm and rolled firmly; the DPC runs through the full wall thickness and links to the floor damp-proof membrane where the detail requires.
