The Filtrexx® Compost Stormwater Blanket (CSWB™) is used as a practice for stormwater runoff reduction and permanent vegetation establishment; used on post-construction soil surfaces and in Low Impact Development (LID) projects. Stormwater blankets are intended for application and use where:

• Reduction of pollutant loading in storm runoff is required
• Land disturbing activities have ceased
• Permanent vegetation is required
• Runoff volume reduction from landscape or drainage area is necessary
• Reduction in the size of stormwater collection, bioretention ponds, and rain gardens is necessary
• Where Low Impact Development ordinances and guidelines must be met

Stormwater blankets are a natural sponge for rainwater and non-concentrated storm runoff. By holding large volumes of rainwater at the soil surface, Stormwater blankets increase infiltration, evapotranspiration, and plant available water that would normally wind up as runoff. These processes restore the natural site hydrology through groundwater recharge and atmospheric water vapor.

The Filtrexx® Slope Protection and Compost Erosion Control Blanket (CECB™) is a practice used in slope stabilization, erosion control, and vegetation establishment. It is used on slopes to stabilize bare, disturbed, or erodible soils on and around construction activities.

• Prior to structural sediment control barriers
• LID, Green Infrastructure, or Green Building practices are recommended or required

Filtrexx® Engineered Soil is a permanent stormwater infiltration practice used to reduce site stormwater runoff volume and loading of sediment and soluble pollutants; such as nutrients, heavy metals, bacteria, and petroleum hydrocarbons, from a contributing watershed or drainage area. Filtrexx® Engineered Soil is manufactured on site by incorporating 2-4 in (50-100mm) of Filtrexx®

Growing Media™ with native soil and tilling to a depth of 6-12 in (150-300mm) to create a functional soil designed for high infiltration, biofiltration, and plant sustainability.

Filtrexx® Engineered Soils improve infiltration by increasing water absorption (water holding capacity), soil porosity, and soil structure through the incorporation of Filtrexx® Growing Media™. Stormwater runoff volume reduction is closely correlated to reduction of sediment and soluble pollutant loading to receiving waters. Filtrexx® Growing Media™ chemically binds soluble water pollutants such as phosphorus, ammonium-nitrogen, heavy metals, bacteria, and petroleum hydrocarbons.

Beneficial microorganisms in Growing Media™ can decompose captured pollutants to less toxic and even beneficial forms, while plant uptake can further reduce captured pollutant concentrations in the engineered soil solution. Soil amendments used to construct Filtrexx® Engineered Soils can be applied with a pneumatic blower, spreader, or similar equipment.

Applications where Filtrexx® Engineered Soils may be used include:

• Around bioretention systems and rain gardens
• Around stormwater and sediment retention ponds
• Parking lot infiltration islands

Filtrexx® Nutrient Removal is a natural flocculent that is used with Filtrexx® stormwater pollution prevention practices, such as sediment control, check dams, inlet protection, biofiltration and bioretention systems. It is specifically used to reduce nitrogen and phosphorus loads in stormwater runoff, particularly on or around sensitive watersheds and receiving waters, TMDL (303d) listed water bodies, land application of fertilizer, land application of animal manure and litter, pet parks, animal feeding operations, golf courses, lawns, industrial areas, parking lots and parking decks, highways, car washes, marinas, and boat docks.

Filtrexx® Nutrient Removal is a natural material that chemically absorbs soluble phosphorus and nitrogen in water and stormwater, thereby reducing transport to water bodies, reducing bioavailability to aquatic plants, and minimizing algae blooms, eutrophication, and low dissolved oxygen levels that can lead to fish kill and collapse of aquatic ecosystems.

Coconut Fiber for Erosion Control

Because natural coconut fiber is 100% biodegradable with a non-invasive design, it provides an easy, natural solution for projects requiring restoration, stabilization, or vegetative growth. These products have been successfully used to help manage Beach Erosion, Coastal Erosion, Soil Erosion, Water Erosion, Wind Erosion, River Bank Erosion, Weathering and Erosion.

Coconut fiber coir logs are a reliable erosion control product designed to aid in the stabilization and re-vegetation of hillsides, banks, shorelines and other areas prone to erosion. Logs are constructed with compact interior cores that have been densely packed with coconut fibers, then covered with an exterior coir mesh netting that helps to keep fibers in place. They are often used on steep slopes or areas with exposure to waves or currents which cause instability on a site.

How Coir Logs Can Help:

Coconut fiber logs are designed to help withstand wave impact and stormwater sheetflow forces without deformation or loss of materials. This helps to ensure maximum erosion prevention, enhance plant growth, and increase microbial activity. They are also a great way to collect and hold mineral and organic particles, providing a stable substrate, and promoting root growth. More importantly, the logs slowly biodegrade and leave a self-maintaining erosion prevention system.

Coir Logs are Placed:

• In flowing water areas: They can be placed directly on the bank, often retaining fill material or securing new channel alignment.
• In standing water: Coir logs are placed offshore to break waves and encourage sedimentation and re-vegetation.

Erosion control products consist of both natural fibers and synthetic fabrics. Depending on the materials used and environmental factors, some fibers will last longer than others during the soil erosion control process.

Natural Fibers
Typically made from materials such as coconut coir, straw and wood fibers that naturally biodegrade over a period of time.

Geotextiles
Constructed from synthetic fibers used to support the soil or other materials underneath roads, rip rap and more. Geotextiles typically feature either a woven or nonwoven construction. Woven fibers are used in separation and stabilization applications, while non-woven fabrics are ideal for areas needing increased filtration.

Why do we use compost and composted materials? Because Nature Can Do What Man Cannot®.
