LL - Litter and Leaf Bag: Polyester mesh bag designed to capture litter, leaves and large debris. These bags will keep storm sewers clear of accumulating leaves, mulch, and pine needles.
IL - IDOT Nonwoven IDOT specified non-woven with polyester reinforcement mesh, primarily for temporary use. This bag is our highest volume design and has been implemented for nearly a decade by the Illinois DOT on road resurfacing and construction projects. The IL NonWoven will remove some hydrocarbons however it will blind prematurely if exposed to considerable silt and clay. The FX bag is a better solution for longer term construction projects (> 12 months).
