VANDEX SUPER is applied to concrete where the active chemicals combine with the free lime and moisture present in
the capillary tract, to form insoluble crystalline complexes. These crystals block the capillaries and minor shrinkage
cracks in the concrete to prevent any further water ingress. However, the Vandex layer will still allow the transmission
of water vapour through the structure. In addition to waterproofing the structure, VANDEX SUPER protects concrete
against sea water, waste water, aggressive ground water and certain chemical solutions. VANDEX SUPER is
approved for use in contact with potable water, and is therefore suitable for the tanking of water storage tanks,
reservoirs, water towers, etc.
