Woven bristle coir soil erosion control blanket.
BioD-Mat® 60 blanket is a completely biodegradable soil erosion control blanket and does not contain any synthetic materials to harm wildlife.
BioD-Mat® 60 blanket is woven from machine-spun bristle coir twines. This semi-permastrong,00% biodegradable, strong and durable bristle coir woven blankets provide higher resistance upon installation while supporting growth and development of vegetation. BioD-Mat® 60 blanket has field functional longevity of 4-6 years. This blanket allows designers and specifiers to go beyond the design limits of other types of organic erosion control blankets. This strong, durable, and biodegradable blanket plays an important role in soil bioengineering. The open weave in the BioD-Mat® 60 blanket allows reseeding before and after installation. The 0.75 in x 0.5 in opening in the blanket allows planting plugs through the blanket without cutting the blanket.
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.
