Vandex Super / Super White Waterproofing Slurries for Concrete
Vandex Super is a cement-based waterproofing slurry specifically designed for concrete waterproofing applications. It is mixed with water prior to application by brush or spray. Other waterproofing slurries from the Vandex range such as Vandex BB75 and Vandex Unimortar 1 provide waterproofing solutions for substrates other than concrete.
Because of its high coverage rate, Vandex Super is very economical in use.
When Vandex Super is applied to a concrete surface, the active chemicals combine with the free lime and moisture present in the capilliary tract to form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage cracks in the concrete to prevent any further water ingress (even under pressure). However the Vandex Super layer will still allow the passage of water vapour through the structure (i.e. the concrete will still be able to "breathe").
In addition to waterproofing the structure, Vandex Super protects concrete against sea water, waste water, aggresive ground water and certain chemical solutions. Vandex Super is approved for use in contact with potable water, and is therefore suitable for the treatment of water storage tanks, reservoirs, water towers, etc...
Vandex Super can be applied to all structurally sound concrete – new or old. It may be applied to either the pressure or non-pressure concrete face (i.e. with or against water pressure).
Vandex Super may be used in conjunction with Vandex Premix. Typical areas of application are:
- Basement waterproofing
- Car park waterproofing
- Waterproofing contiguous piling and diaphragm walls
- Waterproofing pile heads and pile caps
- Concrete slabs (floor, roof, balcony etc...)
- Construction joints
- Water-retaining structures
- Swimming pools
- Sewage treatment plants
Note: Vandex Super and Super White are not intended as decorative materials.
Dry Sprinkle Application (Concrete Slabs)
As a waterproofing solution for new concrete slabs, Vandex Super can be applied as a dry powder to wet concrete slabs after the initial set. It is then power-trowelled into the surface – providing in-depth waterproofing of the slab.
Vandex Super White
Vandex Super White is a version of Vandex Super with white cement used as the binding agent (rather than grey Portland cement). It is used as a concrete waterproofer in exactly the same way as Vandex Super, and is often specified where a lighter finish is an advantage – e.g. car parks, drinking water reservoirs.
Vandex Super is covered by BBA certificate number 04/4188.
Vandex Super is CE marked in compliance with EN1504-3. It is approved under WRAS in the UK for use in drinking water structures.
