Coir Rolls with biodegradable netting

Salix have developed a Coir Roll which is fully biodegradable, providing effective erosion control without the use of plastic nets.

Most coir rolls are supplied with a polypropylene netting for the required tensile strength, but Salix has developed a suitable biodegradable netting instead. Where polypropalyne netting can last over 50 years in the environment, coir only lasts 3-5 years. By this time, the vegetation will be the main form of erosion control and the plastic netting is not always needed.

A Coir Roll provides bank protection at the toe of the slope, whilst providing an effective growing medium simultaneously with erosion control. As the coir biodegrades, the wetland plants within the Coir Roll will consolidate with the riverbank to become the effective erosion control.

Coir Rolls can come pre-established with native wetland plants, or unplanted.
