• drinking water structures

Properties:

It consists of grey Portland cement, specially treated quartz sand and a compound of active chemicals.

When VANDEX SUPER is applied to a concrete surface 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 (even under pressure).

However, the Vandex 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, aggressive ground water and certain chemical solutions.

VANDEX SUPER is tested for use in contact with drinking water.
