Waterproofing of tanks and pools - Part 1: Requirements and principles for design and execution

2Scope / Description

This draft standard applies to the design, selection, and construction of waterproofing layers for tanks and containers made of solid building materials (such as reinforced concrete and masonry) where water is applied to the inner walls of the tanks and containers. Waterproofing materials include roll-type and liquid-applied waterproofing agents. This includes waterproofing of drinking water storage tanks, reservoirs, swimming pools, rainwater regulating tanks, and their inlet and outlet structures. Tanks and containers can be built-in, free-standing, or underground embedded. Throughout the standard text, the term "tank" is used to refer to tanks and containers. This draft standard does not apply to:
　——Waterproofing of the back of tanks exposed to moisture and water (see DIN 18533);
　——Waterproofing against hazardous liquids as defined in the Water Resources Management Act (WHG);
　——Post-construction waterproofing in building maintenance or architectural heritage preservation, unless the methods described in this standard are applicable;
　——Impermeable components, such as those designed and fabricated according to the DAfStb Guidelines for Impermeable Concrete Structures. DIN 18535-1 should be used in conjunction with the rest of the specification, which contains specific provisions for the planning and construction of various waterproofing construction methods.
