The product, known internationally as Kyowa Filter Units and manufactured by Kyowa, is a flexible mesh bag filled with rock or riprap that forms a foundation-free protection system for bridges, roads, railways, embankments, culverts, shorelines and rivers.

The New Zealand operation has supplied the product since 2016 to government and private sector projects, including local government agencies, road development authorities, ports, construction companies and industrial companies. The bags are positioned as a sustainable civil engineering alternative to gabions, large rock, blockstone, free riprap and rock mattresses, requiring no foundations or bed preparation and supporting rapid fill and deployment either on site or pre-filled off site. According to the company, more than 1.1 million Bluemont Rock Bags™ have been installed in over 24,000 civil projects worldwide since 1987, and the bags are made from 100% recycled materials. Notable applications cited include protecting offshore navigational aids in the Great Barrier Reef region, disaster management following the Wamberal Beach erosion, and scour protection for the Wave Swell Energy unit at King Island.
