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.

Weber Roof Waterproofing System

weber primer 401

High performance acrylic based waterproofing primer

weber primer 401 is a high-performance acrylic based waterproofing primer with excellent bonding agent properties with the substrate, like gypsum board, cementitious board, new and old concrete. It yields into overall strength properties of a waterproofing coating system.

weberdry ACR seal

Ready-to-use liquid applied waterproofing

weberdry ACR seal is a ready-to-use, fibre - reinforced elastomeric, super flexible acrylic waterproof coating. It is easy to apply and forms a seamless waterproof barrier which is UV resistant and capable of handling light foot traffic. These properties along with its crack bridging ability make it ideal for waterproofing roofs and terraces, as an exposed waterproofing coat.

weber tap-seal

3-ply waterproofing membrane to be used at intersection of pipes and boards

weber tap-seal is 3-ply flexible waterproofing membrane to be used at the intersection of pipes and boards.

wp acc

Flexible waterproofing tape for joints and corners

webertape stickon is special coated 3-ply tape: high extension in the cross direction and rigid lengthwise, thin, high tenacity.

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.

Pipe joints must be treated with weber tapseal. refer product page for details.

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.
