Title: GEOTEXTILE
Abstract:
The present invention concerns a geosynthetic element (1) for a geotechnical engineering application. The geosynthetic element (1) comprises: bacteria carriers (3) for carrying bacteria arranged to be propagated from the geosynthetic element (1) to a surrounding geomaterial; and a flow network comprising openings on its surface to allow a reactant to escape the flow network to the surrounding geomaterial along the flow network to produce solid calcium carbonate when in contact with the bacteria. The reactant flow network further comprises a set of inlets for feeding the reactant into the flow network, and a set of outlets for recovering at least a part of the reactant from the reactant flow network.
