BioD-Mat® 60 erosion control blanket is woven from machine-spun bristle coir twines. This semi-permanent 100% biodegradable, strong and durable bristle coir woven erosion control 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. These blankets allow designers and specifiers to go beyond the design limits of other types of organic erosion control blankets. These strong, durable and biodegradable blankets play an important role in soil bioengineering. The open weave in the BioD-Mat® 60 blanket allow 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. When selecting and specifying woven coir mats, 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. BioD-Mat® 60 erosion control blanket does not contain any synthetic materials to harm wildlife.
