Submitted by: Muhammad

The components of a typical waterproofing system on the roof of a pumping station are as follows:
☛ Right above the structural finish level of the roof ( concrete ) a uniform thickness screed is applied so as to facilitate the application of the waterproofing membrane. The surface provide for the membrane should always possess good cohesion properties and must be thin so as to prevent any un-uniformity. This thin layer also acts as a layer of thermal insulation.
☛ Right above this layer the waterproofing membrane is deployed to secure the water tightness of the roof.
☛ In order to enhance the thermal insulation of the roof an insulation board is sometime placed right above the waterproof membrane. The insulation board helps in the maintenance of a stable temperature in both weathers.
