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 .
