Filter Units can be used for temporary measures where a collapse has occurred or is imminent, or for longer term civil engineering projects. Ideal for situations where ease of installation and versatility is important, they have been successfully installed on uneven slopes and surfaces.

As a recognized fast production product (about 6 minutes to produce a 2t net) with a single point lifting ring, the Rockbags offer a more efficient and cost-effective option compared to traditional solutions, resulting in significant project cost savings.

Filter Units can be filled at site or outside the worksite, be stacked, stored and transported.

A Filter Unit Rockbag is produced by placing the net into the production frame and filling it with stone or rocks.  The recommended granulometry of the filling material is 50-200 mm. The diameter of a 2t net is 1.9m and a height of 40 cm. By reducing the amount of filling material the height is adjustable. Filter Units are highly maneuverable due to the single point lifting system which allows for a quick, easy and safe installation or removal. Even after removal, Filter Units can be reutilized in a different application.
