Siltsack - High-Flow - Type B (includes curb deflector)
Siltsack is a sediment control device made with a permeable geotextile fabric that can handle strong surges of stormwater. The unique design allows water pass through the catch basin filter while filtering stormwater runoff and preventing silt and sedimentation from clogging the drain system.
The Type B Siltsack is made particularly for combination drains where a drop inlet is coupled with a curb inlet. The built-in curb deflector prevents sedimentation and silt from entering the drain system through the curb inlet as well as the drop inlet.
Routine inspection of a Siltsack’s collected sediment level is important to prevent “ponding” around storm drains.
A Siltsack can be emptied and re-used for the life of the construction project if well maintained.
