Product Description
BioD-Mat® 60 blanket is woven from machine-spun bristle coir twines. This semi-permanent 100% 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. 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 0.50 in opening in the blanket allows planting plugs through the blanket without cutting the blanket.
Applications
- Slope Stabilization
- Streambank Stabilization
- Channel Restoration

| CT 7 coir mat shown in the photo does not meet BioD-Mat® 70 specs. Use of #7 in the trade name does not mean that it is equal in quality to BioD-Mat® 70. CT 7 product not only has a larger open area than BioD-Mat® 70 but it is also weaker in tensile strengths. As you can see: CT 7 is more comparable to RoLanka’s BioD-Mat® 60 |
