Description
VANDEX BB 75 E Elastic Waterproofing Slurry
VANDEX BB 75 E is a two-component, polymer-modified cementitious waterproofing slurry designed to protect concrete, masonry and rendered surfaces against water ingress while accommodating minor structural movement and cracking. By combining VANDEX BB 75 powder with VANDEX Elasticizer PK 75 liquid polymer, it forms a flexible, waterproof coating with excellent crack-bridging performance and outstanding adhesion to a wide range of mineral substrates.
Tested to withstand water pressure up to 7 bar (70 metres head of water), VANDEX BB 75 E provides long-lasting protection for structures exposed to moisture, groundwater and hydrostatic pressure. Suitable for both internal and external waterproofing, it can be applied by brush, trowel or spray equipment and is also used as the bonding adhesive for VANDEX Construction Joint Tape within waterproofing systems.
