Vandex Concrete Grey
A cement based, crystal growth sealing waterproofing system for both positive and negative pressure applications.
Description
VANDEX CONCRETE GREY is a cementitious, ready-mixed product providing in-depth waterproofing where a light grey colour similar to aged concrete is desired.
Areas of Application
- substrate: concrete
- active or passive waterproofing and protection against water and moisture
- foundations, slabs, retaining walls, construction joints, swimming pools, backfilled structural elements, etc.
- drinking water structures
Properties
It consists of Portland cement, specially treated quartz sand and a compound of active chemicals. When VANDEX CONCRETE GREY 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”). VANDEX CONCRETE GREY is tested for use in contact with drinking water.
