StormCatcher is a multipurpose tubular BMP, used where a temporary robust filter berm is needed. The textile is tough and long-lasting. The fill is patent-pending heat-treated rice hull mixed with gravel that forms a high-flow, high sediment retention 3-dimensional filtering matrix. This bio-reactive material targets waterborne pollutants such as oil sheen and heavy metals. Similar products that use old ground up tires just can’t do this. Because rice hulls originate in water, they are slow to degrade in wet conditions, but will eventually biodegrade –rubber won’t. StormCatcher is lighter and easier to maneuver than rubber wattles and no more getting poked with wires because there are no wires –it’s just environmentally friendly heat-treated rice hulls and gravel.
