Wall constructions are always affected by humidity. And moisture or disruptive microorganisms which occurrence they provide, are only the iceberg to of possible difficulties. When water penetrates the wall surface, difficult chemical compounds cause the organism structural rupture. Wall waterproofing will help you to solve this problem.

Waterproofing walls exterior methods

Waterproofing wall exterior depends not only on the material with which it will be conducted, but also on the chosen way of humidity prevention. We propose you several waterproofing methods at option.

Surface

This method is conducted with materials that resist well the decay, putrefactive processes. Sealing membrane, glass tissue, asbestos felt can be easily referred to such materials. Bitum mastic serves as adhesive material.

Attention. Asphalt felt, roofing felt are are not good for such method because its performance specifications are out of durability norm line.

The waterproofing walls exterior with surface fining begins with the first layer application – the bitum one. Them two asphalt felt layers are applied. And afterwards one more bitum layer above the fastened asphalt felt is applied.

It is important to pay attention to fining quality. There should be no damages, bubbles, detachment. Having noticed the deviation start the work from the beginning immediately having peeled all defects and fined it once again.

Membrane method

Waterproofing house exterior walls can be easily conducted with different mastics, bitum. The last one has a lot of blame. Membrane materials have quite thick, voidless mass that gives the surface special strength and water resistance during the hardening. The coating with fibrous glass fabric is considered to be the most reliable one. In this respect it is used for higher complexity objects.

Penetrating method

This method is highly valued as a concrete structure waterproofing, it has a good resistance power to crack occurrence.

For brick wall waterproofing the PVC membrane is possible that is applied fast and is quite cheap in comparison to other waterproofing materials.

The waterproofing walls material grey slurry K11 refers to penetrating materials. The waterproofing mineral slurry can carry a load right after its application to the surface. It has sea water, low temperatures high resistance.

Powder method

This method is used for waterproofing exterior walls and represents a mixture looking like plaster both according to consistence and bottom application method. It is made cement-based with synthetic gum addition. The asphalt concrete and polymer-cement refer to this method modification.
