Waterproofing of Subgrade Constructions by Curtain Grouting.

Curtain grouting is a method for waterproofing subgrade constructions where the sealing of the leakages in the construction is technically not possible or economically not sensible. By this kind of grouting the capillaries and cavities in the soil surrounding the construction are filled and sealed with polymeric gels. The grouted soil forms a new waterproofing body outside the structure. The properties of the used gels are described as well as the necessary steps to control the quality, including preliminary enquiries of the masonry, planning and execution of the grouting process, quality control and documentation. Also ecological aspects of grouting in soil are discussed.
