Geocomposite (Geogrid/Nonwoven Geotextile), Combigrid® 30/30 Q6 R 156 C or equivalent, made by NAUE GmbH & Co. KG, used as reinforcement under base and/or subbase courses over soft ground with additional separation and filtration function, supply and installation according to manufacturer’s installation guideline.

Combigrid® 30/30 Q6 R 156 C is a geocomposite made of stretched, monolithic, textured polypropylene flat bars (PET) with welded junctions and a mechanically bonded filter geotextile which is welded within the geogrid structure, used for reinforcement in many fields of civil engineering, including landfill engineering, road construction and hydraulic engineering. The geogrid must not be coated with a separate polymer. Quantities are based on area to be covered. Wastage due to overlaps and cuts has to be included.

The following parameters have to be considered for proof of equivalency:
