RockSoxx Weighted, durable, and reusable
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.

Frequently asked questions
RockSoxx is a weighted, durable, and reusable tubular filtration unit designed to trap sediment from stormwater runoff that flows onto roadways from construction activities. Filled with a 50-50 blend of 1½” dust-free limestone gravel and composted hardwood chip, RockSoxx intercepts sediment-laden runoff at inlets, ditches, and perimeters without requiring trenching, stakes, or anchors.
RockSoxx stays in place through its own weight – the dense limestone gravel and composted hardwood chip fill provides enough mass to resist displacement from concentrated stormwater flows. This eliminates the need for trenching, staking, or anchoring, saving installation time on active construction sites.
RockSoxx is engineered to fit a variety of inlet configurations, including flat inlets, curb checks, sidewall inlets, inlet surrounds, and stone inlet protection setups. Its modular design allows units to be arranged in flexible configurations to match the specific geometry of each site.
Construction site managers choose RockSoxx because it combines durability, reusability, and anchor-free installation in a single filtration unit – reducing both labor costs and material waste compared to single-use silt fencing or straw wattles. Its high-strength, UV-resistant multi-filament polyester knit netting allows it to be driven over repeatedly while maintaining full sediment capture effectiveness throughout the job.
Yes – RockSoxx is specifically engineered for high hydraulic flow, meaning water passes through the unit efficiently without backing up or causing ponding. The UV-resistant, high-flow polyester knit netting allows stormwater to move through while capturing sediment particles in the limestone gravel and hardwood chip fill.
RockSoxx is built to withstand concentrated stormwater flows that would displace or damage lighter sediment control products. The double hog ring closure, high-strength netting, and weighted fill keep the unit intact and effective even under repeated hydraulic stress or vehicle traffic.
RockSoxx is best suited for check dams and ditch checks, inlet protection, gutter-line checks, and perimeter sediment control repairs. Its modular, anchor-free design makes it especially practical for sites where sediment control configurations need to change as construction progresses.
Yes, RockSoxx is fully reusable – it is designed to be moved, repositioned, and run over repeatedly without losing structural integrity or filtration performance. The 6-inch pig tails built into each unit allow workers to handle and reposition them quickly without specialized equipment.
Yes – MKB Company recommends pairing RockSoxx with BlackHawk Inlet Filter Mats for enhanced sediment removal efficiency at storm drain inlets. This combination addresses both coarse and fine sediment particles, providing a more complete inlet protection system on active construction sites.
