Verification and Control of Geotextiles According to DVO and ÖN S 2082
The Austrian landfill regulation DVO 2008 and its attachments generally admit to use geosynthetics as an alternative to mineral components used as sealing or drainage elements. The requirements needed to proof equivalency are described for each landfi ll class separately. Paragraph 5 and 6 and attachment 3 of the DVO defi ne the appropriate minimum requirements or limit values respectively.
Geosynthetic clay liners (GBR-C) have to proof the same long term percolation as amineral sealing (MS) layer. Furthermore the percolate must not exceed 5 % of the annual rainfall when used as a single capping system. Drainage mats, geocomposites often as thick as about one cm, have to proof long term lateral drainage capacity, comparable to a 30-50 cm drainage layer of coarse gravel 16/32 mm. Two landfill projects in Austria are used to present the experience in design and construction with regards to specific criteria from landfill regulation DVO.
