Coir Logs for Erosion Control


Erosion Control Coir Log Detail

coir logs for erosion controlQuestion: Hi. I am wondering about your coir logs for erosion control. What is the thickness and length? Also, what is coir fiber? Is it a chemical compound?

Answer: Thank you for contacting us! Coconut Coir Logs are all-natural erosion control products that are designed to help reinforce banks, stabilize slopes, and support other areas prone to erosion. Due to their natural coir fibers, coir logs are often used as an environmentally safe solution for erosion.

Erosion control coir logs are created using fibers from coconut husks. These fibers are typically soaked in water for an extended period of time in order to soften them up. This helps to increase their strength, flexibility, and lifespan.

Note: Coir, like many products, is sourced from overseas. During these challenging times, due to trouble with supply and getting the products through the port systems, many products are less available. When they are available, they are more expensive. Coir is one of the products affected this way, across the entire industry. However, there are alternatives. As a practical and affordable alternative to coir logs or wattle, you might consider sediment filter logs. They are biodegradable, environmentally friendly, and perform in all the same ways that coir log and wattle do. Please see Sediment Filter Logs (pdf). Call us for pricing or with questions.

How Coir Logs Are Constructed

coconut coir fiberCoir products are essentially by-products from coconut harvesting. Coir is derived from the husks of coconuts and then soaked in water for increased flexibility. After this process has been completed, coir fibers are then separated out to form various types of coir.

Standard coir fiber is typically used to fill the inside of the coir logs. This coir fiber is shorter in length, allowing it to be densely packed within the log.

Coir twine, by contrast, is a longer fiber that offers increased strength. This long coir twine is taken and woven into a net that features openings of 2 inches by 2 inches. This is used for the outer net of the coir log to provide a reliable outer structure for holding in the coir fibers.

Standard Density Coir Logs

These are the industry standard for use in average conditions and at a price point that's budget friendly. 100% Biodegradable, the Standard Density Coir Logs are made of 100% coir encased in a 2"x2" coir netting. Coir Logs for erosion control promote a natural solution to erosion control and slope stabilization, while creating an environment that supports vegetative growth for long term erosion control as the coir eventually biodegrades.


High Density Coir Logs

High density coir logs for erosion control are recommended for use on rigorous terrain, areas exposed to high flow or harsh environmental conditions. They are also a reliable erosion control solution for streambanks and lakeshores, as well as for slope stabilization. Manufactured with 100% coir fibers encased in a rhombic coir netting, these high-density coir logs are known for solid performance in the most demanding situations and for the longest duration in the field.


Pre-Drilled Coir Logs

Amazingly convenient, the installation of these coir logs is a snap. They use fewer stakes; simply secure them with stakes through the pre-drilled slots in the logs. The slots can also be used for planting seedlings. The slots are approximately 2 feet apart. Pre-Drilled Coir Logs for erosion control are available in standard or high-density options and a variety of sizes.

Coir Log Features

coir log streamsCoir logs are typically constructed into a couple of different models and sizes for erosion control applications. Standard sizing includes:

  • Diameters: 12", 16", or 20"
  • Lengths: 10'

The diameter of your coir log is chosen based on your area location and the type of erosion you are trying to control. While the coir log is typically offered in lengths of 10 feet, several logs are often joined together to form a longer erosion control barrier.

Coir logs for erosion control can be custom built to a longer length, however, dealing with smaller logs is often the best option as the logs are easier to handle and easier to ship.
