Vandex BB75 Waterproofing Slurry
Vandex BB75 is a cementitious waterproofing slurry (tanking slurry) with hydrophobic properties, resistant to water and moisture.
Vandex BB75 is applied by trowel or spray to surfaces such as concrete, masonry, and render, which have to be sealed and protected against the influence of water and moisture. Typical areas of application include:
- Basement / cellar waterproofing and refurbishment
- Underground car parks
- Retaining walls
- Lift pits
- Tanks / reservoirs / water treatment works
- Sewer / sewage treatment plant waterproofing (BB75Z)
- Fish ponds & water features
Once cured, Vandex BB75 tanking slurry forms a waterproof coating (tested up to 7 bar). It can be employed against active and passive water pressures, and is approved for use in contact with potable water. The initial and final bonding capability of Vandex BB75 is excellent, making it suitable for application to horizontal as well as vertical surfaces. It is durable, resistant to frost and heat afer setting, whilst remaining vapour-permeable. The properties of Vandex BB75 can be further enhanced by using the "Vandex PK75" or "Vandex Cemelast Liquid" polymers as a gauging solution – the resulting products being referred to as Vandex BB75 E and Vandex Cemelast.
Vandex BB75 is not intended to provide a decorative finish. In most cases, the Vandex BB75 waterproofing layer is covered with a suitable plaster such as Vandex Refurbishment Plaster.
