RSS Flüssigboden®  liquid soil


RSS Flüssigboden liquid soil is a mixture

of source material and additives (plasticizer, accelerator, stabilizer) as well as mixing water and possibly special lime. In special cases, other materials can be added for the targeted modification of single properties.


RSS Flüssigboden liquid soil is the result

of the application of the liquid soil method. The method was developed from 1998 on by the research institute for liquid soil Forschungsinstitut für Flüssigboden GmbH and the engineering office Logic, and various variants of it were patented. It was used for the first time as a term and coined in the sense of restoring the original soil situation after excavation.


The liquid soil method makes it possible

to produce a temporarily flowable and self - compacting backfilling material from any type of excavated soil, industrially produced and natural aggregates and other mineral substances, and thereby to restore properties similar or equal to the natural soil in the sense of soil mechanical and soil physical properties.


Liquid soil does not contain any environmentally hazardous additives

and therefore has no unacceptable influence on the soil (BBodSchG) and the soil - groundwater path of action (BBodSchV).


Liquid soil is a frictional, cohesive, and solidifying

material from the group of temporarily flowable, self-compacting backfilling materials. It can have consistencies ranging from plastic to flowable, whereby the soil mechanical properties of liquid soil can be controlled.Liquid soil has no closed, rigid, squeezing foreign structures eg caused by hydraulic binders. In re-solidification, liquid soil exhibits high volume stability under placement conditions becauseof the permanently stable water binding of most of the added water.
