Correct and permanent external basement waterproofing
Key Facts
Dry and absolutely watertight basements are not a matter of course. Optimum basement waterproofing belongs to the most important requirements for a building which is to remain untroubled by moisture damage over the longer term. As moisture can penetrate basements from different sides, it requires different waterproof systems in order to guarantee comprehensive protection and dry and mould free living.

1 Evening out the substrate (if required)
Level the surface and close open joints (up to 5 mm) with AQUAFIN-1K in one coat by trowel or with suitable spray equipment.
2 Waterproofing wall-floor junctions
Form a mineral-based waterproof fillet with ASOCRET-M30 at the wall/floor transition. Apply a bonding slurry beforehand. This can be with either ASOCRET-M30 or AQUAFIN-1K.
3 Waterproofing pipe penetrations
Apply AQUAFIN-RB400 with a 4 mm notched trowel, bond ADF-pipe gasket without folds and then completely overcoat.
4 Waterproofing the foundation base transition
Apply a minimum of 2 coats of AQUAFIN-RB400 with a brush, steel float or suitable spray equipment. Install up to at least 30 cm above and at least 20 cm below the ground level.
5 Polymer modified bitumen coating - waterproofing
Apply COMBIDIC-2K-PREMIUM, COMBIDIC-2K-CLASSIC or COMBIFLEX-EL by trowel at a thickness appropriate for the type of moisture exposure. Apply the high build bitumen coating with a minimum 10 cm overlap over the foundation base waterproofing (picture 4).
6 Protective and slip fleece (with cationic bitumen)
Recommended application for masonry work, mandatory with concrete structures: Cut the ASO-Systemvlies-02 to the correct length and bed into the fresh bitumen coating without folds or overlapping, then smooth flat.
7 Protective and drainage board
Once the waterproof coating has dried, apply blobs of the high build coating COMBIDIC-1K to the unlaminated side of a suitable protection and drainage element and press onto the substrate, which has been waterproofed.
