Tips for success |
Performs better than synthetic permanent mats as well as
provide environmentally friendly erosion control. Strong, durable, yet 100%
biodegradable. |
|
|
|
|
 |
BioD-Mat 70 blanket is woven from machine-spun bristle
coir twines. The 100% biodegradable, strong and durable bristle coir woven
blankets provide higher resistance upon installation while supporting growth
and development of vegetation. BioD-Mat 70 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 70 blanket allow reseeding before and after installation. The 0.4" x 0.5" opening in the
blanket allow planting plugs through the blanket without cutting the
blanket. The 9.84 ft (3m) and 13.1 ft (4m) wide blankets have a seam. |
