Siltsack - Type B (includes curb deflector)

  • $45.00

Product Information

The Type B Siltsack is a sediment control device designed for combination drains where a drop inlet is coupled with a curb inlet. The Siltsack is made of a permeable geotextile that allows stormwater to filter through while preventing silt and sediment from clogging the drain system.

The Type B Siltsack features a built-in curb deflector, allowing it to protect both the drop and curb inlet at the same time. Siltsack can be used as a primary or secondary sediment control device and must be maintained on a regular basis to function properly. Optional overflow holes are offered to make the Siltsack effective even in the most extreme weather events. 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.
