Erosion Control Coir Logs


Coir Products for Soil Stabilization

natural erosion control on the shorelineGEI Works' erosion control coir logs are natural fiber products designed to provide soil stabilization and support along river banks, slopes, steams, hillsides, and other erosion prone areas. Offering a high level of strength and reinforcement, these coir fiber rolls feature densely packed mattress coir fibers that are placed inside a tubular coir twine netting. Both components are all natural and biodegradable, making coir logs safe for the surrounding environment.

The most appropriate size for coconut fiber logs depends on the flow and slope of your project. Standard coir logs are available in diameters between 9 and 20 inches and either 10, 16, or 20 feet in length. Twine can be used to join multiple sections of coir fiber rolls together.
