  • a self-sealing seal or source seal is achieved by the use of dried bulk material, whereby a subsequent processing step can be omitted.
  • the surface seal has a self-healing effect in case of damage or subsidence.
  • spherical bodies are particularly easy to dry through and lead to a particularly low adhesion of the body and to a particularly low transport weight. In addition, very few cavities are present, whereby a particularly rapid sealing is possible. In addition, the bodies are particularly easy to manufacture.

  • the source material 14 may consist, for example, of bentonite beads and preferably of bentonite powder.
  • the body 10 may be dried and solid. Upon contact with water (not shown), the source material 14 begins to swell. In FIG. 1 is shown from top to bottom, as the source material 14 begins to swell and is getting bigger.
  • the size of the body 10 is dependent on the conditions of the individual case, in principle grain-graded bulk material is desired in order to achieve the highest possible density of storage of the body in a surface seal.

  • the outer bentonite grains incorporated in the bodies 10 as the source material 14 begin to absorb water.
  • the bodies 10 increase in volume (see FIG. 3 ) and begin to self-seal the surface to be sealed. Due to the further progress of water absorption of the body 10, these are constantly plastic, so that the swelling process continues to progress.
  • the further layers 26, 28 and 30 are applied, as required.
  • the ballast layers cause a mechanical vertical pre-compaction of the sealing layer 22.
  • the now further penetrating into the sealing layer 22 water is continuously absorbed by the source material 14 in the bodies 10, so that there is a continuous increase in volume of the body 10 (see FIG. 3 ).
