Photos of water proof membrane sheet
36 photographs of applying membrane sheet on the roof
Performance of the membrane sheets shall be done in dry season,otherwise the moisture might be entraped between roof & membrane sheet wich will cause bubbles.
As it is obvious in the photographs a primer shall be applied before membrane sheet installation. This is to make a good bonding and also to eliminate dust. The primer will also reduce the moisture absorbation of the light weight concrete or any other finishing.
The corners shall not be 90 degrees. As a result of that have to make chamfer by mortar before applying the primer.
Testing shall be done by water ponding after closing the downpipes .
