Kyowa Rock Filter Bags are erosion and scour protection units suitable for installation on river banks, in the sea, in lakes and creeks, at roads and rail embankments where stabilisation or protection is required.
They can be successfully installed on uneven, sloping surfaces and integrate perfectly in challenging topographic and watercourse environments.
Kyowa Rock Filter Bags can be used for temporary measures where a collapse has occurred or is imminent, or for longer term civil engineering projects. There have been over 17,000 civil projects with rock bags with no failures.
Successful projects throughout Australia, New Zealand and the Pacific Islands include Brisbane, Central Queensland, Far North Queensland, Central West NSW, New Zealand ports, Western Australia and NSW South Coast.
