Coir Logs are made from 100% natural coconut fibre compacted into an outer mesh of bristle coir twine. They incorporate biological, ecological and engineering aspects of erosion control into their design, producing a structure, that when vegetated, controls shoreline and streambank erosion. Coir Logs are fully biodegradable within 5-10 years, decomposing into a natural medium that promotes plant growth. As this happens, a well established root system develops that will blend into aquatic environments and successfully hold banks and shorelines in place, preventing further erosion by diminishing the force of waves and stream flow. This is why vegetating is recommended. Once wetland plants are established, Coir Logs also provide a natural habitat for wildlife.
Whenever reasonable and practical, priority needs to be given to the preventing, or at least minimising soil erosion rather than allowing the erosion to occur and trying to trap the resulting sediment.
