(Rate may vary as per site requirement)
Flat areas : 1.15 M2 /M2 per layer with 10 cms. side laps and 15 cms. end laps. Base flashing : 100x35 cms. with 15 cm. end laps, 0.40 M2 / linear Mtr. Average wastage : 3 - 5 %The underside of the membrane should be torched just enough to superficially melt the bitumen. Excessive heating may damage the reinforcement.
Overlaps should be re-heated from the top and resealed with a trowel to ensure seam integrity.
