Vandex Concrete Grey can be applied to either the pressure or non-pressure faces of concrete and is excellent for solving the problem of water seepage through porous or cracked concrete in both new and old structures.
Vandex Concrete Grey is an in-depth cementitious waterproofing compound which supplies active ingredients to the host concrete under the forces of osmosis which react with the free lime in the host concrete to produce dendritic crystals. The crystals formed effectively block the pores, capillaries and minor cracks in the host concrete preventing the passage of liquid water, however will still allow the passage of water vapour through the structure, thereby allowing the structure to breathe.
