Most of the Kyowa rock bags we installed are now out of sight.
On land they are usually covered by soil and vegetation.
In rivers, ports and on beaches they are typically below the surface in water or covered by sand.
Fish hide between the small rocks, safe behind the rock bag net.
Whatever covers them: rock bags stabilise and protect infrastructure.
We know because we test.
We know because more then 1,100,000 Kyowa rock bags have been installed.
Kyowa rock bags are made from 100% recycled materials.
