|
BioD-Mat 40 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 40 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 40 blanket allow
reseeding before and after installation. The 0.75" x 0.75" 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. |
|
|
BioD-MatTM 40 blanket is available in 4
different roll sizes. |
|
3.28 ft x 83 ft = 30 SY/roll
(1m x 25m =25 m2/roll), |
|
6.56 ft x 166ft= 120 SY/roll (2m x 50m =100 m2/roll),
|
|
9.84 ft x 166 ft =
180 SY/roll (3m x 50m =150 m2/roll) |
|
13.1 ft x 83 ft= 120 SY/roll (4m x 25m =120 m2/roll). |

General Specifications |
|
The
blankets shall be woven from coir twines. Coir twines shall be made of
bristle coir obtained from freshwater cured coconut husks which shall be
machine spun to a uniform diameter. The blanket shall also conform to the
following properties. |

Advantages
- 100% biodegradable.
- Economical compared to synthetic mats.
- Open weave allows re-seeding, when necessary.
- Easy to install and to walk on the mat.
- Wildlife will not feed on the mats.
- Higher resistance to UV light compared to
synthetic mats.
- Open weave allows planting through the mat
without cutting the mat.
- Coir twine move independently, create no threat
to wildlife movement.
- Support establishing vegetation better than
synthetic fiber.
- Woven from machine twisted bristle coir fiber
twine; strong and durable.
- Hold moisture for seed germination and seedling
growth.
- Higher tensile strength and provide initial
support in bioengineering applications.
- Last 4 - 6 years and provide aesthetically
pleasing applications.
- Made from freshwater cured bristle coir and dark
brown in color.
