Abstract

A land drain (1) to be used for the electrokinetic drainage of soil is made by integrally extruding a biplanar mesh structure tube (2) of electrically-conducting plastics material so that the tube (2) is of trellis construction. Every alternate longitudinal outer strand (3) contains a tinned copper wire (4) which is passed through the stationary outer die of the die head as the respective strand (3) is extruded. The tube or core (3) so formed is wrapped with a suitable drainage filter fabric (6).
