An environmentally friendly alternative to hay bales and expensive Rip Raps or cement stabilisation techniques, Coir Fibre Logs are ideal for constructing check structures, managing changes in stream flow velocity, shaping channels and stabilising shorelines. A natural planting medium for vegetation and made from 100% coir (coconut) fibre, Coir Fibre Logs are a totally biodegradable material that last up to four years. They are easily installed and will blend naturally into the environment over time.
