Delivery of a multi-layered needle-punched stable fibre nonwoven with a filling of quartz sand, Secutex® HB 501, of the company NAUE GmbH & Co. KG or equivalent, provide as a filter geotextile for applications in hydraulic engineering according to TLG (Edition 2018) of the Federal Institute for Waterway Engineering (BAW), Karlsruhe and professionally installed according to the manufacturers installation instructions. The unrolled sandmat has to be overlapped at the joints and to safeguard against wind suction or flow attacks by taking appropriate measures. Overlap losses are to be included.

The following parameters are, for the demonstration of equivalence, observed:
