Abstract: A flexible seal for constructions and method of using such seals where the seals include a mixture of soil and a polymeric additive including polymeric methacrylamide, which additive opens a water casing around soil grains, wherein 1 m3 of soil contains up to 0.5% by volume of the additive wherein the additive also contains saponified paraffins or further contains between 15 kg and 25 kg of cement and/or lime per 1 m3 of soil which cement and/or lime in turn contains 1% by weight to 10% by weight of the additive or wherein a proportion of between 20% by weight and 50% by weight of water is added to the mixture to make it capable of flow.

Abstract: The present invention relates to a means for and a method of sealing constructions. In order to provide a means for and a method of sealing constructions which permits flexible, inexpensive and permanent sealing of new and already existing constructions, with a high degree of sealing integrity, by introducing a core sealing means, it is proposed in accordance with the invention that the means for sealing constructions comprises a mixture of soil, preferably argillaceous materials and/or coarse clay, and an additive for breaking open the enclosing water around the grain. In regard to the method it is proposed that the mixture of soil and an additive is injected into the construction or is sprayed on at the surface.
