Waterproofing Roofs & Terracese's
Efficient waterproofing of roofs and terraces can be achieved by adopting proper construction practices. For a tropical region with heavy rainfall, (like Bombay or places on the west coast), a 'Weathering Course' typically consists of an insulating layer with an integral or separate finishing layer of IPS and a waterproofing course suitably located or laid directly over the R C slab. It is essential that no rainwater stagnates on the roof. A proper slope and adequate number of drainage outlets can achieve this. The requisite slope is obtained by varying the thickness of the insulating layer. Or when the roof slab is large in area, the slope or fall is often provided by making it's (the slab) top surface sloping to the desired extent.
