Providing and fixing APP (Atactic Polypropylene Polymer) modified prefabricated
five layer 2 mm thick water proofing membrance, black finished reinforced with
glass fibre matt consisting of a coat of bitumen primer for bitumen membrane @
0.40 litre/ sqm by the same membrance manufacture of density at 25°C, 0.87 - 0.89
kg/ litre and viscocity 70 - 160 cps. Over the primer coat the layer of membrane
shall be laid using Butane torch and sealing all joints etc., and preparing the surface
complete. The vital physical and chemical parameters of the membrane shall be as
under : Joint strength in longitudinal and transverse direction at 23°C as 350/300
N/ 5cm. Tear strength in longitudinal and transverse direction as 60/80N. Softening
point of membrane not less than 150°C. Cold flexibility shall be upto -2°C when
tested in accordance with ASTM, D - 5147. The laying of membrane shall be got
done through the authorised applicator of the manufacture of membrane 2 mm (for corrugated roof sheets).
