Weber Roof Waterproofing Solutions
When water spoils the terrace .... we guard it......
The slope of the terrace must be maintained towards the drain pipe so as to ensure that there is no puddles of water or stagnant water. Further, certain areas on a roof like corners (floor-to-wall joints), pipe outlets, parapet walls require special attention as these are most susceptible to leakage. These must be reinforced suitably before laying the waterproofing membrane.

Roof Waterproofing Solution
Generally, 2-3 coats of 0.5 mm thick waterproofing membrane must be applied for durable waterproofing. The second coat must always be applied perpendicular to 1st coat
Primer penetrates into pores of the concrete and enhances adhesion of subsequent coat with base substrates. It also improves the coverage.
All corners of the floor must be filled with cement sand mixture modified with polymer-like webertec SBR so as to have a curved surface. This ensures water does not accumulate on the edges which are susceptible to leakage
Alternatively, edges can be reinforced with corner treatment tape - weber Stickon. Apply weberdry ACR Seal on edges with a brush and place weber Stickon firmly so that half of it covers the wall and rest covers the floor. Apply another coat of weberdry ACR Seal over this completely covering weber Stickon and its edges.
Cut open the cracks with a mechanical hand grinder or with chisel and hammer. Fill the cracks with a mixture of 5 parts cement with 1 part of webertec SBR.
Waterproofing primer and membrane must cover at least 1 ft height of parapet walls. This ensures water does not seep in through the edges of the waterproofing membrane. Plus after completion of waterproofing, the edges of a waterproofing membrane on paraphet walls must be sealed with 2-3 mm thick layer of a mixture of 5 part cement and 1 part of webertec SBR.
The damaged floor must be repaired with mixture of 5 parts cement, 15 parts sand, 4 parts water and 1.5 parts of webertec crete.
White coloured surfaces have a tendency to reflect sunlight and thereby cause a temperature differential. Thus if the waterproofing membrane is white it will reduce the heat load.
