Cementitious waterproofing

Effective cement-based waterproofing systems

Cementitious waterproofing is a very easy, yet effective, method of waterproofing for areas that are often exposed to water and damp. Modern polymer modified cement-based waterproofing systems are ideal for many concrete and masonry applications, offering puncture resistance due to the nature of the application, which is hard and strong. It is suitable for new and existing structures.

Due to its excellent weathering resistance, cementitious waterproofing is ideal for water tanks, swimming pools, walls, bathrooms floors and terraces.  As cementitious waterproofing products are not as flexible as liquid waterproofing products, they are more suitable for flat surfaces.

CemSeal X

GAST manufactures its own cementitious base polymer waterproofing product, namely CemSeal X. It is a seamless and flexible polypropylene fibre reinforced acrylic based cementitious waterproofing membrane that can be used as a final finish surface and can also be tiled if so desired. CemSeal X is mixed with portions of OPC cement to create a thixotropic slurry. Our product is biocide stabilised and, therefore, inhibits bacterial and fungal growth. This product can be used for multiple applications, including balconies, walkways, stairways and showers.
