Erosion Control

We help you prevent erosion in agriculture and land development projects.

About this market

Our erosion control products and components provide flexible containment and protection functionalities that keep erosion in check.

 

SWM netting, yarn, and fibers play an essential function in rolled erosion control products (RECPs). Our customers use our plastic netting as the containment element in their Erosion Control Blankets (ECBs), Turf Reinforcement Mats (TRMs) and Sediment Retention Fiber Rolls (SRFRs), usually known as wattles. We also manufacture an entire portfolio of Prostran® synthetic fibers which are used as a filler in TRMs and polypropylene yarn to stitch and secure ECBs.  

 

SWM is an active member of the International Erosion Control Association (IECA) www.ieca.org and the Erosion Control Technology Council (ECTC) www.ectc.org

 

What is Erosion Control?

Erosion Control is the practice of preventing or controlling wind or water erosion in agriculture, land development and construction. Vegetation, such as grasses and windflowers, and other materials such as straw, fiber, stabilizing emulsion, protective blankets, etc., are placed to stabilize areas disturbed by grading operations, reduce loss of soil due to the action of water or wind, and prevent water pollution.

 

Types of Erosion Control Products

Based on information gathered through the Erosion Control Technology Council (ECTC), erosion control products can be classified in three main categories:

 

1) Rolled Erosion Control Products (RECPs)

     a) Erosion Control Blankets (ECBs)
     b)Turf Reinforcement Mats (TRMs)

 

2) Hydraulic Erosion Control Products (HECPs)

 

3) Sediment Retention Fiber Rolls (SRFRs)

SWM manufactures netting components and synthetic fibers that manufacturers utilize in the assembly of their final erosion control products. Our netting, yarn, and fibers portfolio is an essential component in Erosion Control Blankets (ECBs), Turf Reinforcement Mats (TRMs), and Sediment Retention Fiber Rolls (SRFRs) — also known as wattles.

Erosion Control Blanket Netting 2.jpg

Erosion Control Blanket Netting

SWM netting is used as the containment material in Rolled Erosion Control Products (RECPs) for temporary and permanent applications. Erosion Control Blanket (ECB) netting is designed to perform during the useful life of the blanket. Dependent on exposure to UV, temperature and other environmental conditions, the netting becomes brittle and tensile strength diminishes.

Wattle Netting

SWM manufactures extruded and knitted netting used as the containment material in Sediment Retention Fiber Rolls (SRFRs), also commonly known as wattles or socks. Our netting provides enough flexibility and movement without sacrificing tensile strength for the most challenging sediment and flow control applications.

PROSTRAN® Synthetic Fibers

PROSTRAN® synthetic fibers are designed and manufactured to provide excellent loft and matrix fill in Turf Reinforcement Mats (TRMs) for permanent erosion control applications. Our Prostran portfolio includes a variety of colors and recycled material that adapt to the requirements of the final erosion control application.
Yarn.JPG

Yarn

SWM yarn is an exceptional high-tenacity polypropylene (PP) yarn used to stitch the layers of rolled erosion controlled products together, providing support and reinforcement. Our yarn is available in a variety of colors and deniers to meet product specifications and performance targets.
ECB-Illustration-SWM-version.jpg

Erosion Control Blanket (ECB)

ECBs are used for temporary applications. They are degradable RECPs composed of processed natural or polymer fibers mechanically, structurally or chemically bound together to form a continuous matrix to provide erosion control and facilitate vegetation establishment.* SWM manufactures two ECB components, the plastic netting used to contain the matrix and the yarn used to mechanically stitch the layers together. Our engineering teams are able to customize netting and yarn configurations to meet specific performance requirements.
TRM-illustration-SWM-Version.jpg

Turf Reinforcement Mat (TRM)

TRMs are permanent RECPs composed of non-degradable synthetic fibers, filaments, nets, wire mesh and/or other elements, processed into a permanent, three-dimensional matrix of sufficient thickness. TRMs are typically used in hydraulic applications, such as high flow ditches and channels, steep slopes, stream banks, and shorelines, where erosive forces may exceed the limits of natural, unreinforced vegetation or in areas where limited vegetation establishment is anticipated.* SWM manufactures three TRM components: the Prostran synthetic fibers used as a matrix, the plastic netting containing them, and the yarn used to mechanically stitch the layers together.

Sediment Retention Fiber Rolls (SRFRs)

SRFRs are manufactured 3-dimensional devices of a specified filler matrix encapsulated within a flexible containment material utilized in sediment and flow control applications. SRFRs are also known as wattles, logs, socks, tubes or fiber rolls. SRFRs, available as prefabricated units, are constructed into tubular configurations comprised of rice straw, wheat straw, excelsior fiber, wood fiber, coconut fiber, compost, flax or a similar matrix material. The matrix material is encapsulated within plastic netting, yielding an approximate functional life of 1 - 3 years³. SWM manufactures the plastic netting containing the matrix materials and can modify netting configurations for diverse erosion control applications.
