Lightly packed coir wattles for effective sediment control
The most versatile natural tool for effective sediment control
BioD-Watl coir wattles are completely biodegradable and do not contain any synthetic materials to harm wildlife.
RoLanka BioD-Watl™ is made from cleaned mattress coir fiber, which is uniformly and lightly packed into a high strength bristle coir twine netting (2 in x 2 in opening). The lightly packed coir fiber allows cleaner water to pass through leaving sediment behind. Flexible, easy-to-use, reusable, natural and biodegradable BioD-Watl™ is an excellent sediment control structure for construction and landscaping projects. BioD-Watl™ is available in 6-in, 9-in, and 12-in diameters and 10-ft, and 15-ft lengths. The excellent filtering ability and the superior durability of coir fibers, compared to other natural fibers, makes BioD-Watl™ a better alternative than straw wattles and wood fiber logs. The biodegradable, yet durable netting in BioD-Watl™ is not only environmentally friendly, but also lasts longer than plastic netting in other types of wattles. Coir wattles can also be used in streambank restoration in low flow velocity streams.
Coir fiber in BioD-Watl coir wattles is packed lightly for sediment filtering. These wattles filter sediment more effectively than all other filtering mediums used in sediment control structures.

Advantages
- Coir wattles provide the most effective BMP’s for sediment control in construction sites.
- Efficient sediment retention. Coir fiber is an excellent filtering medium. Lightly packed coir fiber allows water to go through it freely while filtering sediment from storm water.
- Completely wildlife safe. Contain no plastic nets and not palatable for wildlife.
- Coir wattles come with strong durable bristle coir twine netting. Coir twine used in the coir wattles has 90 lbs. strength.
- Extremely flexible coir wattles are easy to install and to maintain.
- They work well with heavy equipment.
- 100% natural and biodegradable. Coir wattles can be clean and reused upon used on paved catch basins.
- Easy to cut and join to any desired length.
- Able to use in streambank restorations in low velocity streams.
- Only material cost, no removal or disposal costs.
- They are strong, durable, natural, biodegradable, environmentally friendly and economical.
- Personal satisfaction with preventing soil loss and protecting aquatic resources.
