Bio Log Erosion Control

Slope Stabilization, Filtration and Erosion Control

coir log supporting streambankBio Log erosion control is an effective method to stabilize shorelines, reinforce slopes, control erosion, or act as a check dam to control silt.

Designed as an environmentally-friendly product, these Biodegradable Coir Logs have an exterior manufactured with a bristle coir twine net and an interior packed with enriching coconut fiber. Designed to enhance the environment they're placed in, coir logs are photodegradable, or easily decomposed by sunlight. As they biodegrade, the nutrient-rich fibers strengthen the existing bank and encourage the area to establish deep root growth.

Depending on your application, erosion control logs can be made with or without knots. This helps to provide you with the product that most efficiently and effectively fits any project or site. See the specs listed below.
