Tool risk reduction measures
100 RISK REDUCTION MEASURES
Sealing of ground-reaching buildings; black tanks
The measure is for waterproofing buildings against ground moisture and seepage water at below-ground structural elements like walls. There are horizontal or vertical sealing methods existing. Horizontal seals prevent that moisture rises up. Vertical seals prevent moisture to enter the building from the sides. There are several solutions available with bitumen (black tank) and with synthetic materials. It is important that vertical seals reach up to 30cm above ground with at least one horizontal seal.
