Bituminous components treated with polyester materials to be in the form of
rolls 1*10m. The Polyester is considering the actual reinforcement layers of
bitumen. Therefore, 200mg of polyester from the highest quality with a
thickness of 4mm
To execute the membrane , there are several stages to be followed:
1- The cleanliness of the roof to be isolated from any flaws or any dust… etc.
2- Execute an area with a thickness of 2cm.
3- Execute a primer layer (cold asphalt) to close layers’ pores which the
isolation to be applied on them, and so as the docking layer shall be between the
cement material and the bituminous material and to close the pores by %100.
4- Execute the membrane with heated welding by Al-Cor under optimal
temperature with a 10cm welding horizontally and 15cm vertically.
5– Test by filling it with water for 72 hours.
6- Execute a smooth layer space with a thickness of 2cm.
