Sika GCC has launched a new innovation in waterproofing membrane to the region - SikaProof® A.


Sika is the global leader in waterproofing and products such as Sikaplan®, Sika’s liquid applied membranes, various coatings and mortars are popular the world over.

Sika has now launched its latest innovation in structural waterproofing to the GCC region. SikaProof® A is a fully bonded, highly flexible membrane system, designed to be used for basement waterproofing on new constructions and for renovation work. The membrane system is applied before installation of steel reinforcement and before the fresh concrete is poured.

This new product combines Sika’s knowledge and expertise from the construction and automotive businesses, namely Sikaplan® FPO membrane and Sikamelt® sealants.

System Build-up of SikaProof® A
SikaProof® A is a waterproofing membrane system that clearly differentiates from traditional solutions. The membrane surface is embossed with a grid pattern, which contains a sealant and is topped by a thin layer of fleece.

In contrast to existing membrane systems, SikaProof® A is fully bonded to the cured concrete, with its layer of specially designed fleece forming a mechanical bond after hardening of the structural concrete. This mechanical key is not influenced by high temperatures during the construction process like normally adhered systems which can peel off when exposed to sunlight.

The sealant in a grid pattern forms “mini” watertight compartments which limits the water underflow if the membrane is damaged or punctured. Because of this sealant grid, moisture or pressured water cannot pass between the membrane and the concrete structure. Compare to non-fully bonded systems, the risk of leaks in basement is strongly reduced due to limited area of potential water migration.


Application of SikaProof® A
Another major advantage is in the way that the individual sheets of SikaProof® A membranes are connected to each other. Instead of time-consuming and complicated welding (the procedure normally used to connect loose laid membrane sheets) SikaProof® A sheets are joined using either the adhesive strip which runs along the longitudinal edge of every sheet or by fastening them together with specially designed self-adhesive tapes. This quick and easy system for adhering sheets is also very cost-effective as it increases dramatically the speed of application and eliminates the need for expensive welding machinery.
