FAQ - Coir Fiber Bio Logs

What Sizes of Coir Bio Log Are Available?

coir logs for stabilizing streambanks and protecting against erosionQuestion: I am interested in finding out more information about coir bio log sizes. We are working on a restoration project, and will probably need several bio logs to be placed side by side along the water's edge. Does GEI Works offer bio coir logs in specific sizes? Are they custom made to meet sizing requirements?

Answer: Great question! Interestingly enough, the answer is yes to both. The Erosion Control Log offered by GEI Works, also known as the bio log or biodegradable coir log, is available in standard sizes but are highly customizable to suit the needs of any restoration project. They're a highly effective tool used to control erosion on slopes, along streams, on banks, and in various other erosion control locations. Coir bio logs sound like the perfect choice for your project.

Coir Log Diameters

Varying diameters work to provide the height necessary to accommodate certain stream or water flow heights. With information about the scope and goals of any erosion control or restoration project, our product experts can suggest the most appropriate size bio log. There are three standard diameters for coir bio log:

  • 12 inches
  • 16 inches
  • 20 inches

Bio Log Lengths

Coir logs are typically l10 feet long. This length provides a significant area of control, without sacrificing any easy of installation. With more expansive, extensive projects where longer lengths are required, several of these coir bio logs can be joined together with the use of coir twine. This sturdy twine ties through the netting located on teh outer ends of the logs to join them together.

How are Coir Bio Logs Constructed?

Coir Logs are bio degradable and 100% naturalGEI Works' coir logs are held together with a biodegradable bristle coir twine netting that's built to last. With 2 in. x 2 in. weave openings, planting seeds for deep roots and stable growth after coir log installation is simple. Regardless of application, project of site, bio logs are designed with the same goal in mind: to secure slopes, stabilize banks, and protect from future erosion.

Coir twine is used to hold densely-packed inner mattress coir. The density of each bio coir log depends on the length:

  • 12 in. Coir Logs: 7 lbs/ft3 or 9 lbs/ft3
  • 16 in. and 20 in. Coir Logs: Density of 9 lbs/ft3

Regardless of size, all coir logs are designed to biodegrade over a period of two to five years, allowing plenty of time for new vegetation to take root.
