Technical Specification of KoirMat^™ 1000

KoirMat^™ is made from well cleaned, high strength, fresh water cured coconut fiber. Coconut fiber is extracted from coconut husks which are submerged in fresh water streams or storage tanks for a period of several months. During this process known as retting, water constantly flows through the coir fiber matrix removing impurities present in the fiber. The clean fiber is extracted and spun into yarn which is then woven into KoirMat^™.

KoirMat^™ erosion control matting is highly versatile with a wide array of applications in bioengineering and erosion control. KoirMat^™ by far exceeds the demand for an environmentally friendly and economic erosion control product.

Benefits:

Coir fiber has one of the highest durability and tensile strengths among all natural fibers. The high lignin content (46% by weight) of KoirMat^™ makes it naturally resistant to mold and rot and hence requires no chemical treatment.

KoirMat^™ naturally absorbs and retains water while retaining its integrity providing an ideal microclimate for the growth of vegetation. KoirMat^™ resembles the soil in its ability to absorb solar radiation to prevent overheating – a problem with many synthetic materials. The natural color of KoirMat^™ makes it aesthetically pleasing. After years of effective erosion control and vegetation anchoring, KoirMat^™ decomposes and joins the natural ecological cycle, providing soil nutrients in the process. Environmentally safe and biodegradable, KoirMat^™ is the preferred choice of erosion control specialists around the world.

Longevity:

Depending on its application and exposure, KoirMat^™ lasts three to six years. This extended longevity period allows enough time to establish adequate vegetation allowing erosion control the way nature intended.

Overview

KoirLog^™s are natural coconut fiber logs with applications in wetland mitigation, shoreline stabilization and stream banks/channel protection. Nedia’s KoirLog^™s are made from double cleaned, unsorted coconut fiber encased in high tensile strength coir twine netting. KoirLog^™s help to dissipate the impact from wave action and flowing water, trap sediments and encourage vegetation growth.

During installation, seedlings or plant cuttings can be planted into the KoirLog^™. Sediment trapped by the KoirLog^™ as well as the inherent property of the coir fiber to absorb and retain moisture provides an ideal medium for vegetation establishment and growth.

Sizes:

KoirLog™s are available in 12”, 16” and 20” diameters. The logs are typically 10 or 20 feet long.

Densities:

KoirLog^™s are available in Normal Density (ND Series) of 7 lbs/cu .ft. and High Density (HD Series) of 9 lbs/cu .ft. KoirLog^™s with a normal density of 7 lbs/cu .ft. (ND Series) are easier to handle, install and plant. The normal density logs also encourage rapid root development. Designers must evaluate the site conditions in order to choose the appropriate size, density and number of tiers of KoirLog^™s to be used. Some parameters to consider are flow velocity, wave height, stream energy, soil type and accessibility to the project site.

Longevity:

Fabric wrapped soil construction is one of the most resilient bioengineering techniques to stabilize streambanks. This technique relies on the strongest type of coir fabric construction to reinforce soil lifts, high density plantings of rows of willow cuttings, native seeds, and in many cases a reinforced stone toe to protect against toe scour. Like all bioengineered designs using degradable fabric, the concept is to rely on fabrics during the initial (three to six years) soil stabilization period. As the fabric degrades, the installed vegetation provides the necessary erosion protection and aesthetic benefits. KoirWrap^™1000 & KoirWrap^™ 1200 are excellent fabrics for this type of bank treatment.

KoirWrap^™ 1000 & KoirWrap^™ 1200 is a double-layered biodegradable erosion control fabric made up of an outer layer of high strength continuously woven coir matting and an inner layer of lightweight jute fabric connected together at regular intervals. KoirWrap^™ 1000 & KoirWrap^™ 1200 is ideal for fabric wrapped soil construction on steep slopes and along streambanks.

Overview

Nedia offers a variety of straw & coconut stitched blankets for erosion control on slopes and channels. These blankets help to stabilize and reinforce the soil until vegetation is established. All blankets are available in photodegradable as well as biodegradable netting (denoted by suffix “B”).

Straw Blankets

The single-netted straw blankets (S300 and S300B), are typically used on slopes 3:1 and flatter as well as in low flow channels. The double netted straw blankets (S400 and S400B) are ideal for 3:1 to 2:1 slopes and for moderate flow channels.
