Abstract

A method for installing thin-walled sealing elements in the fabrication of slotted walls in the soil. The thin-walled sealing elements are plastic foils with vertical connecting elements at the vertical edges. A connecting slot is flushed out between a newly made slotted-wall section and the interior of the adjacent slotted connecting tube of the previously installed sealing element. The slot and the interior of the connecting tube are filled with a support suspension. Then a new sealing element is threaded through the filled connecting slot into the previously installed connecting tube.
