Black Hawk
Black hawk MKB
Silt sacks have limited sediment storage capacity and can easily blind whereby causing street flooding. Blackhawk™ has a much higher sediment storage capacity because sediment is kept above the grate. It’s unique design – vertically oriented coir fibers, scalloped edging, hi-flow holes, and emergency dewatering plugs, make this device the most robust in it’s class.
Blackhawk™ is held to the grate with high-strength rubberized magnets so installation, servicing, and removal is a snap – no skid steer or backhoe needed. This device can be cleaned and re-used multiple times.
