External waterproofing to basements - mineral-based
Key Facts
A dry and totally watertight basement is not a matter of course. Optimum basement waterproofing belongs to the most important requirements for a building if it is to remain untroubled by long term moisture damage. As moisture can penetrate a basement from many sides, it needs different waterproofing systems in order to guarantee comprehensive protection and dry and mould-free living.
1 Evening out the substrate (if required)
Surface levelling 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 mineral-based waterproof fillet with ASOCRET-M30. Apply a bonding slurry beforehand. This can consist of ASOCRET-M30 or AQUAFIN-1K. Alternatively, a waterproof fillet can be constructed from ASO-Dichtband-2000-S.
3 Waterproofing pipe penetrations
AQUAFIN-RB400 applied with a 4 mm notched trowel and smoothened, ADF-Rohrmanschette bonded free from folds and subsequently fully overcoated.
4 FPD (liquid applied polymer modified High Build waterproofing membrane)-MDS (Mineral-based waterproofing slurry) - Waterproofing
AQUAFIN-RB400 applied by trowel, brush or spray techniques to exposure related thickness.
5 Protective and drainage board
Once the waterproofing coat has dried, the protective layer can be bonded in a full bed of a mixture comprising AQUAFIN-RB400 / 0.1—0.35 mm Quartz sand and using a suitable notched trowel using the Buttering-Floating technique.
6 Perimeter insulation
Lay the insulation butt jointed and offset in accordance with the manufacturer's guidelines and fully bond with AQUAFIN-RB400.
