FAQ
Vandex applications form a firm mechanical bond with the substrate concrete and react chemically with the concrete.
The physical and chemical interaction does not affect the concrete negatively. On the contrary: a Vandex treatment prevents water ingress, reduces vapour transmission and enhances the mechanical and chemical resistance of the substrate concrete.
What is Vandex used for? Vandex offers a wide range of
cementitious products for waterproofing, concrete repair and
concrete protection. Typical applications are:
- Below ground waterproofing of
concrete and brickwork
- Waterproofing on the negative water
pressure side
- lining of drinking water
reservoirs
- protection of sewage treatment
facilities
- protection of agricultural
structures
Please have at look at our specifications
Most Vandex products are based on high quality portland cement and fine graded sand. Chemical additives give special properties like waterproofing, excellent workability etc. All products are subjected to a continuous control of quality.
Cementitious products require curing to fully develop their properties. The water has to react with the cement and may not evapourate too fast. This will leave pores and may cause cracking of the coating. In general Vandex coatings should be kept damp for 5 days. For product specific details please refer to the application guidelines.
