Flexible Rock Bags are highly durable net-bag that could accommodate a variety of fill choices from gravel, stones and crushed concrete. The net is made from highly UV stablised polyester yarn and tested against abrasion, eliminating possible corrosion problems that arise from structures made from steel and abrasion from sand particles.
Contributed from its flexibility, FabriFlex FRB can conform to various challenging terrain yet able to maintain a steeper slope angle as compared to riprap owing to the restrain of the net structure. When deployed as a hydraulic structure (i.e., revetment, scour protection, etc.), the system can achieve similar performance as riprap constructed using a flexible rock bag with smaller stone size.
