Guideline DWA-M 512-1E Sealing Systems in Hydraulic Engineering Part 1: Earthwork Structures

It covers surface- and internal-sealing systems for soil structures in hydraulic engineering as they are applied in practice. Described are surface and internal sealing systems used in earthwork structures, including asphalt and concrete sealing systems, geosynthetic clay liners, mineral sealings, geomembranes, fully grouted riprap, sheet pile walls and internal sealing systems made of hydraulically bound sealing-wall materials (concrete, plastic concrete, injections, jet grouting, diaphragm walls, thin slurry diaphragm walls, soil-grouting processes). For each of these sealing systems, a summary is given of possible applications, construction materials, methods of placement, design principles, quality assurance and maintenance requirements, and reference is made to the latest developments and their applications.
