External waterproofing of basements - with Bitumen
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 with ASOCRET-M30 in one or with AQUAFIN-1K in a minimum of two coats by trowel or with suitable spray equipment.
2 Waterproofing wall-floor junctions
At the wall/floor transition, construct a waterproof fillet with ASOCRET-M30. Apply a bonding slurry beforehand. This can be with either ASOCRET-M30 or AQUAFIN-1K. Alternatively, the waterproof fillet can be produced from ASO-Dichtband-2000-S.
3 Waterproofing pipe penetrations
Apply COMBIDIC-2K-PREMIUM with a 4 mm notched trowel and smoothen, bond the 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 Priming
Before using COMBIDIC-2K-PREMIUM or COMBIDIDC-2K-CLASSIC, the substrate must be primed with ASOL-FE, diluted 1:5 with water.
6 Polymer modified bitumen coating - waterproofing
Apply COMBIDIC-2K-PREMIUM, COMBIDIC-2K-CLASSIC 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).
7 Protective and drainage board
Once the waterproof coating has dried, apply blobs of the high build coating to the unlaminated side of a suitable protection and drainage element and press onto the substrate, which has been waterproofed.
8 Perimeter insulation
Coller l‘isolant conformément aux instructions du fabricant, serré, en décalant d‘une rangée à l‘autre, sur toute sa surface, avec COMBIDIC-2K-CLASSIC ou COMBIDIC-2K-PREMIUM.
