Abstract (en)
[origin: EP1614812A1] The method involves superimposing components such as a drainage layer (4), perforated annular small drainage pipes (5) with a series of perforations, and a filtering layer (31). The superimposed components are driven by drive units towards a needling machine whose needle plate comprises of space for passage of the drainage pipes. The components are coupled together by needle punching. An independent claim is also included for a geo-composite material comprising drainage layers, drainage pipes and filtering layers.
