Where to Place a Coir Log

  • coir logsFlowing Water Areas: Coir fiber rolls can be placed directly on the bank, often retaining fill material or securing new channel alignment.
  • Standing Water: Coconut coir logs are placed offshore to break waves and encourage sedimentation and re-vegetation. They can also be used for wetland stabilization. Other standing water applications include placing coir logs along lake shores or even small ponds to protect against erosion.

Coconut products such as blocks, logs, and mats are also recommended products for soil bio-engineering. For more information, check out our Coir Log Installation Page.
