Providing and laying APP (Atactic Polypropylene Polymer) modified prefabricated
five layer 3 mm thick water proofing membrane, black finished reinforced with
non-woven polyester matt consisting of a coat of bitumen primer for bitumen
membrane @ 0.40 litre/ sqm by the same membrane 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 650/450N/5 cm. Tear strength in longitudinal and transverse direction as 300/
250N. 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 manufacturer of
membrane. 3 mm thick
