Answer: GEI Works offers coir wattles and logs in standard lengths with multiple diameter options available. Coir wattles and logs are easy to manage and maneuver during install, as well easy to connect for longer erosion control projects. All coir products are biodegradable and 100% natural, as they enrich the soil and encourage deep root establishment as they break down.

Coir Wattles

coir wattlesCoir wattles are similar to coir logs in size and shape; however, wattles are not as densely packed. As a result, wattles are often used for filtration purposes, while coir logs work well for stabilization.

coir material close upCoir Material is a durable fiber taken from the husk of coconuts during the coconut harvesting process. Coir logs and wattles contain the following material: bristle coir twine (for the outer netting) and mattress coir (inner material). Coir products are relatively waterproof and resistant to saltwater damage. Water submersion does not cause quick degradation in coir material as it does in other less abrasive materials.
