Vandex BB75 from Safeguard Europe is a cementitious waterproofing tanking slurry, offering hydrophobic properties, resistance to water and moisture.
The tough, elasticised coating protects structural elements such as foundations, slabs and below-ground walls from moisture and water ingress; but also provides sealing solutions for reservoirs, tanks and domestic water features.
Vandex BB75 can be applied by trowel or spray to surfaces such as concrete, masonry, and render; and areas of application would include: retaining walls; underground car parks; lift pits; basement and cellar waterproofing and refurbishment; tanks and ponds; and water and sewage treatment works.
Vandex BB75 is composed of cement, quartz with graded grain-size distribution and selected additives. Its initial and final bonding capability is excellent, making it suitable to be applied to horizontal as well as vertical surfaces. In addition, it is durable, resistant to frost and heat after setting, whilst remaining vapour-permeable. It is available in 12.5kg tubs.
The tanking slurry cures to be ready for skin plaster coats, tile adhesives, vapour permeable, alkali resistant paints or other decorative coatings in around 28 days.
It forms a waterproof coating that can be employed against both passive and active water pressures up to 7 bar – and so is particularly suited to waterproofing underground. It will bridge up to 0.4mm in concrete an can be used to fill cracks and protect areas of potential cracking.
Once set, the coating resists extremes of frost and heat as well as carbon dioxide, so it can also be employed as an anti-carbonation coating as part of a surface protection system for concrete in accordance with EN1504-2. It is also tested for use in contact with potable water supplies.
You can use Vandex PK75 or Cemelast Liquid polymers as a gauging solution, to further enhance the properties of Vandex BB75.
Variants of BB75 include Vandex BB White which is a white version based on Portland cement, suitable for use on exposed surfaces. Its companion product, Vandex BB75 Z, is suitable for use in sewage treatment planes and in foul inspection chamber refurbishment due to its enhanced sulphate resistance.
The Vandex BB range offer durability to common waterproofing tasks. Armed with the tanking slurry and its variants, an operative can protect anywhere that needs robust waterproofing, whether that is a cellar, lift pit, swimming pool, reservoir or car park.
