1. Vandex products provide long-lasting waterproofing protection for basement structures when properly applied, forming an integral part of the concrete structure. 2. Their application requires thorough surface preparation to remove laitance and contaminants from the concrete surface. 3. Vandex products must be precisely mixed and applied according to the technical data sheet, with careful control of material consumption, temperature conditions during application, and proper curing afterwards.

10. Three elements of a
successful
Vandex application
1. Surface preparation

11. How it shouldn’t be !!
• The laitance is still existing

12. Surface preparation
All concrete to be treated must be
clean and have an ”open” capillary
system.
Remove laitance, dirt, grease, etc. by
suitable means.

13. Concrete without any surface
preparation

14. Concrete which received a
surface preparation by high
pressure water jetting
• Aggregates are visible

15. Concrete which received a
surface preparation by water-
sandblasting

16. Water-sandblasting

17. Crack repair
Routing out visible cracks not subject to
movements that exceed 0.3 mm

Vandex application
1. Surface preparation
2. Product application

21. Application of Vandex products
Prewatering
Surfaces must be carefully prewatered
prior to the Vandex application.
The concrete surface must be damp
but not wet.

22. Simple test by hand

23. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates

24. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
Control of material consumption in
relation to the surface => correct layer
thickness

25. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
Control of material consumption in
relation to the surface => correct layer
thickness
When problems arise, stop the application
and investigate => damage limitation

26. Do not apply the products at temperatures
below the values indicated on the product
data sheet or on frozen substrates
Control of material consumption in
relation to the surface => correct layer
thickness
When problems arise, stop the application
and investigate => damage limitation
Record batch number of applied material

27. Mixing
Place in a clean container and stir for at least 3
minutes with a mechanical mixer.

28. Mixing

The mixing times have to be respected
precisely !

29. Mixing

The amount of water may – depending on
environmental conditions and batch variations –
differ slightly from the specified quantity.

30. Mixing
