Coir logs are tubes filled with coconut fibre that are tightly packed, and then bound with coir netting. Coir logs are 100% biodegradable, perfectly blending in with the natural environment and habitat for both plants and animals. Ideal for establishing vegetation, managing water velocity changes in streams and rivers, stabilising shorelines and shaping channels.
Often used in and around open drains to slow water runoff, produce a natural wall or protection barrier for surrounding plants and soil, and capture sediment in drainage lines and swales.
Coir logs can also be used for sediment entrapment, wave and wind protection of:
- Environmentally sensitive areas where there is a requirement for the product to naturally break down and blend into the natural surroundings
- River banks and streams
- Coastal shorelines, where it can also be used as an alternative to rip rap along shoreline structures
- Swale drains
- Steep slopes and gullies where the installation of silt fence would be difficult
- Open drains along roads where water and sediment can be captured
- Gutters and footpaths

WHY CHOOSE COIR LOGS?
- Helps to stabilise riverbanks and minimise long term environmental impact from heavy flow and sediment movement
- Offers a solution to scour repair and river stabilisation in sensitive environments, compared to heavier hard faced solutions
- Acts as a micro-climate to promote plant growth
- Made from 100% coir netting which slowly biodegrades between 4 to 10 years, depending on site conditions
- Provides immediate protection to shorelines once installed
- Flexible structure that allows it to curve and adapt to any ground surface, existing vegetation and river banks
- Quick and simple installation
- Variable lengths available, ranging between 2 to 6 metres
Installation
Coir logs are normally installed with wooden stakes at the mean water level and then suitable plants are installed into the top part of the log. Depending on the application, coir logs can be:
- Stacked in several layers
- Strung together to form a shoreline chain
- Fitted traverse to the flow of the river on a layer of brushwood which juts out into the stream

FUNCTION
Erosion & Sediment Control
The use of a geosynthetic to prevent soil or other particle movements on the surface slope. Acts to reduce soil erosion caused by wind forces, rainfall impact and surface water runoff. The use of geosynthetics in erosion control is to maintain soil cover either as a temporary measure offering protection from soil loss whilst vegetation is established or as a permanent control measure, typically on steeper slopes or high-water velocity situations.
