Weighted, durable, and reusable

Filtrexx Advanced Tubular Filters

Trap sediment from stormwater runoff that flows onto roadways from construction activities with Filtrexx RockSoxx.

These weighted, durable, and reusable filtration units are designed to withstand concentrated flows without the need for trenching, stakes, or anchors. The high-strength netting and double hog rings ensure that RockSoxx can be moved around and run over repeatedly while still maintaining effectiveness throughout the entire job.

RockSoxx filters are designed to be used for a variety of inlet configurations including: flat inlet, curb check, sidewall inlet, curb check, inlet surround, or stone inlet protection. Combine RockSoxx with BlackHawk Inlet Filter Mats for additional sediment removal efficiency and peace of mind on your construction site.

Advantages of RockSoxx include modular pieces for flexible configurations, high hydraulic flow to prevent ponding, no need for anchors due to its weight, UV-resistant high-flow netting, Hi-Vis Safety Orange color for visibility, a blend of limestone gravel and composted hardwood chip fill, easy handling with 6-inch pig tails, and a double hog ring closure for security.

RockSoxx is ideal for various applications such as check dams/ditch checks, inlet protection, gutter-line checks, and perimeter sediment control repairs. Protect your construction site today with Filtrexx’s RockSoxx.
