Woven bristle coir soil erosion control blanket.
BioD-Mat® 40 blanket is a completely biodegradable soil erosion control blanket and does not contain any synthetic materials to harm wildlife.
BioD-Mat® 40 is a natural and biodegradable woven coir soil erosion control blanket. RoLanka ’s BioD-Mat® 40 soil erosion control blanket is woven from machine-spun bristle coir twines. This semi-permanent 100% biodegradable, strong and durable bristle coir woven erosion control blanket provides higher resistance upon installation while supporting growth and development of vegetation. BioD-Mat® 40 woven soil erosion control blanket has field functional longevity of 4-6 years. The strength and durability of this blanket allows designers and specifiers to go beyond the design limits of other types of organic soil erosion control blankets. This strong, durable, and biodegradable soil erosion control blanket plays an important role in soil bioengineering and wetland restoration applications. The open weave in the BioD-Mat® 40 soil erosion control blanket allows reseeding before and after installation. The 0.75 in. x 0.75 in. opening in this soil erosion control blanket allows planting plugs through the blanket without cutting the erosion control blanket. The 9.84 ft (3 m) and 13.1 ft. (4 m) wide blankets have one seam in the mat.
Recommendation for choosing a woven coir blanket.
When selecting and specifying woven coir erosion control blankets, designers should not only consider the unit weight, but also the wet tensile strengths, coir type, open area as well as machine direction and cross direction twine counts.
