The method includes the steps of: providing and using bottom protective tube mats (10), consisting of a water-permeable, multi-ply geotextile fabric, in which at least a lower ply (17) and an upper ply (18) are connected directly to one another along a number of parallel connecting lines (11; 15), wherein flexible tubes (12) are formed between neighboring connecting lines (11; 15) that are separate from one another and each have at least one filling opening (13); laying out the bottom protective tube mats (10) on the bottom area of the landfill basin; laying out embankment protective tube mats (10) on the embankment ring, wherein the flexible tubes (12) are aligned in the direction of the slope of the embankment or at an acute angle thereto; and filling each flexible tube (12) individually with an aqueous suspension and sealing the filling openings (13). ## Claims ### Claim 1 Method for setting up a protective sealing layer in a landfill basin for industrial and mining slurries, wherein the landfill basin comprises at least one bottom area and one embankment ring, which are covered at least to a maximum fill level with a single or multilayer bottom sealing layer, said method comprising the steps of: a) providing and using bottom protective tube mats consisting of a water-permeable, multi-layered geotextile fabric in which at least one lower layer and one upper layer are directly connected to one another along a plurality of parallel connecting lines wherein, between adjacent connecting lines, whereby separate flexible tubes are formed, each having at least one filling opening; b) laying out the bottom protective tube mats on the bottom area of the landfill basin; c) laying out embankment protective tube mats on the embankment ring, wherein the flexible tubes are aligned in the direction of the slope of the embankment or at an acute angle thereto; and d) filling each flexible tube individually with an aqueous suspension and closing the filling openings. ### Claim 2 (depends on 1) The method as in claim 1, wherein the flexible tubes are filled with the slurry to be deposited in the landfill basin. ### Claim 3 (depends on 1) The method as in claim 1, wherein the protective tube mat is woven in at least two separate layers and in that the lower and upper layer are interwoven along connecting lines. ### Claim 4 (depends on 1) The method as in claim 1, wherein the protective tube mat is formed of at least two layers of a geotextile fabric and in that the two layers are sown together along connecting lines. ### Claim 5 (depends on 1) The method as in claim 1, wherein, below the bottom sealing layer, an additional sealing layer is arranged, which contains a swellable bentonite solid material mixture. ### Claim 6 (depends on 1) The method as in claim 1, wherein the protective tube mats are installed overlapping and wherein during the filling first the flexible tubes of a protective tube mat lying on top are filled and then the flexible tubes of an underlying protective tube mat are filled. ### Claim 7 (depends on 1) The method as in claim 1, wherein the embankment protective tube mats are provided with a filling opening that is arranged in an end region. ### Claim 8 (depends on 1) The method as in claim 1, wherein the bottom protective tube mats are provided with at least one filling opening that is arranged in a central longitudinal region of the flexible tubes. ### Claim 9 (depends on 1) A geotextile protective tube mat for carrying out the method according to claim 1, comprising at least two layers of a water-permeable, multi-layered geotextile fabric, in which at least one lower layer and one upper layer are arranged along a plurality of parallel connecting lines are interconnected, wherein a flexible tube is formed between each of the connecting lines, said flexible tube having at least one filling opening, wherein the flexible tubes are separated from each other and have at least one filling opening each. ### Claim 10 (depends on 9) The geotextile protective tube mat as in claim 9, wherein the geotextile fabric is a polypropylene fabric. ### Claim 11 (depends on 9) The geotextile protective tube mat as in claim 9, wherein a UV protective layer connected at least on one side to the protective tube mat, which is formed from a plastic fiber fleece.
