SiltSoxx SiltSoxx controls costs while you control runoff.

SiltSoxx is a compost filter sock – and the original silt sock best management practice (BMP) – manufactured by MKB Company for sediment control on construction sites and erosion-prone areas. Filled with organic compost media and enclosed in a durable mesh sleeve, it intercepts and filters sediment-laden stormwater runoff across a wide range of field applications.

SiltSoxx controls sediment by acting as a permeable compost-filled barrier that slows, spreads, and filters stormwater as it passes through the sock’s organic media. The compost fill captures suspended sediment particles while allowing clean water to pass through, delivering superior filtration performance validated by third-party testing under ASTM D6459 standards.

SiltSoxx installs without trenching and goes in approximately three times faster than traditional silt fence, according to installation time comparisons. Pre-filled units arrive on pallets through MKB’s nationwide distributor network, ready to deploy directly to the field with minimal labor and equipment.

SiltSoxx is available in three product lines – Original, Natural Original, and Natural Plus – each engineered for different project requirements and environmental conditions. The Natural Original uses cotton fiber mesh with up to 12 months of functional field longevity, while the Natural Plus uses wood fiber mesh rated for up to 18 months, and both are 100% biodegradable, eliminating the need for field removal.

SiltSoxx outperforms silt fence and straw wattles in sediment removal efficiency, as demonstrated by independent large-scale testing conducted by TRI-Environmental under ASTM D6459 protocols. Beyond filtration performance, SiltSoxx lowers total project cost by reducing installation labor, minimizing maintenance requirements, and simplifying removal – factors that silt fence and straw wattles cannot match.

Yes – SiltSoxx is in compliance with most state and federal agency requirements, including the USEPA, AASHTO, USDA NRCS, and US Army Corps of Engineers (US ACE). It is also a USDA Certified Biobased product and is Made in the USA, making it a reliable choice for projects with strict environmental and procurement standards.

For the Original SiltSoxx mesh, removal involves simply cutting the mesh and spreading the compost fill – a fast, straightforward process. The Natural Original and Natural Plus product lines are 100% biodegradable and can be left in place permanently, breaking down naturally over 12 to 18 months respectively, with no field removal required.

SiltSoxx is suitable for a broad range of stormwater and erosion control applications across construction, land development, and infrastructure projects. Specific applications include check dams, perimeter control, inlet protection, runoff diversion, slope interruption, sediment traps, and concrete washout containment.

SiltSoxx is available pre-filled on pallets through MKB Company’s nationwide distributor network, making it accessible for projects across the United States. To locate a distributor near you or to inquire about distribution partnerships, contact MKB Company directly through mkbcompany.com.
