Weber Exterior Wall Waterproofing Solutions

When water spoil Exterior Walls .... we guard it......

Hairline cracks developed on the plastered surface acts as an entry gate for safe passage of water and other gases into a concrete structure. This weakens the structural strength and the damp environment promotes the growth of fungus. To prevent this, cracks must be suitably treated with polymer-rich material. To avoid reoccurrence of such cracks in future application of an elastomeric waterproofing coat over entire exterior walls is highly recommended

Exterior Wall Waterproofing Solution

Development of hairline cracks is a natural process as water mixed in the concrete evaporates and this results into slight shrinkage of the plastered surface. Concrete plaster being rigid cannot accommodate this stress due to shrinkage and temperature fluctuations which in turn leads to the development of cracks.

All contaminants, old coat of paint, flaking paint must be removed with a wire brush or a mechanical grinder. Algae or fungus must be removed by giving a biocidal wash.

No. Waterproofing membrane does not stop the development of cracks in concrete. But waterproofing membrane designed with certain crack bridging ability. This property ensures that cracks developed on concrete are not replicated on the top surface and thereby prevents water and gas ingress.

Cut open the cracks with a mechanical hand grinder or with chisel and hammer. Fill the cracks with a paste of 5 parts cement with 1 part of webertec SBR.

Mix weber primer 401 with equal quantity of water and apply with roller. For more details please click here.

Mix the waterproofing membrane uniformly before application. Do not dilute material unless recommended. Apply the membrane at the uniform thickness and do not try to increase coverage than recommended as this would adversely affect final film properties.

Waterproofing membrane must cure completely before being subjected to harsh environmental factors. If chances of rains persist, better delay the application of the waterproofing membrane.
