Sika South Africa – manufacturers of bonding, sealing, damping, reinforcing and protection chemicals -use Fibertex WP 90 fabrics to provide a supporting substrate to improve the waterproofing characteristics of waterproofing resins. In this case, the waterproofing material is a cementitious slurry – branded by Sika as Cemflex. This waterproofing material ensures that all gaps are filled and also increases the longevity of the waterproofing installation
Fibertex WP 90 waterproofing fabrics – manufactured from UV stabilised virgin Polypropylene staple fibres – are highly efficient carrier substrates for various waterproofing saturates, including bituminous, cementitious and acrylic materials.
“Fibertex WP 90 waterproofing membranes offer a high level of chemical stability under a wide pH range and for this reason these membrane fabrics are particularly well suited for installation in areas where the textile may be in contact with acids or alkalis,” says Lance Woolley, business development manager, Fibertex South Africa. “This flexible and durable material, with good substrate-to-saturate adhesion properties, ensures easy application in all areas, including tight corners and right-angle edges.”
Applications for WP 90 geotextiles include waterproofing installations to create a dry environment – for example in the basements of buildings, in tunnels and in underground transport systems. Waterproofing applications for protection against deterioration include flat-roof structures, decks, external balconies and multi-storey structures, as well as terrace gardens and highway structures. This fabric is also suitable for waterproofing for functionality in reservoirs and water towers, as well as water and sewage treatment works.
Fibertex specialists recommend that users follow the specific manufacturer’s instructions for the particular waterproofing emulsion being used.
Fibertex WP 90 waterproofing fabric is manufactured locally at the Fibertex plant in KwaZulu-Natal. The basic strength of Fibertex geotextiles is obtained by needle-punching the fibres, which provides a strong, yet elastic bonding. The fabric also undergoes infrared treatment during the manufacturing process to create a friction surface, with added thermal bonding, on the one side.
