Abstract: The present invention concerns a soil-treatment method and system, comprising at least one electricity generator (10) and at least two electrodes (11, 12), as well as at least one pumping device (20), characterised in that the system comprises at least one geocomposite (2) that contains at least one portion of at least one of said electrodes (11, 12) and which includes at least one filtering layer (21) and/or at least one draining layer (22), and in that at least one portion of at least one of said electrodes (11, 12) comprises carbon.

Abstract: The present invention relates to a system, a method, a geocomposite and a fluid recovery connector in aggregates 5 (S), the system being characterized in that it comprises, on the one hand, at least one layer, so-called barrier layer (5), having permeability adapted to the blockage of fluid (G, L) and beneath which is arranged at least one geocomposite (2) comprising perforated mini-drains (23) and at least one layer, so-called 10 through layer (22) having permeability adapted to the passage of fluid (G, L), and on the other hand, connectors (4) arranged to connect the perforated mini-drains (23) to discharge pipes (3) connected to at least one pumping device (6), such that at least one fluid (G, L) present in the aggregates (S) can reach the interior of the perforated mini-drains (23) and be discharged to 15 the pumping device (6).

Abstract: A geocomposite for positioning under a geomembrane comprising at least one first geotextile covered by at least one second geotextile at least one electrically conductive textile being positioned between the second geotextile and the first geotextile. The conductive textile having a module for connecting to a phase of an electric generator. The geocomposite being in the form of one or several strips at the edges of which the second geotextile, the first geotextile and the electrically conductive textile are separate from each other, the geocomposite comprising perforated ringed mini-drains positioned parallel with each other on the first geotextile and covered with the second geotextile.
