Coir Logs: What They Are, What They're Used For, and Where to Buy Them in Sydney

What Are Coir Logs?

Coir logs (also known as coir wattles or coconut fibre logs) are cylindrical rolls of dense, biodegradable coconut husk fibre, wrapped and held together in a coir or synthetic mesh netting. They’re a natural, eco-friendly alternative to sandbags and silt fencing, widely used across civil, landscaping and environmental projects for erosion and sediment control.

Coir logs are available in a range of diameters and lengths, allowing them to be selected based on the flow rate, slope, and scale of the site they’re protecting.

What Are Coir Logs Used For?

Coir logs are a go-to solution wherever erosion control needs to be effective, low-impact, and biodegradable:

Stabilising creek banks, embankments and slopes against erosion caused by water flow and rainfall
Slowing stormwater runoff and trapping sediment on civil and residential construction sites
Streambank restoration and bioengineering projects, where a natural material is preferred over synthetic alternatives
Erosion control on newly landscaped or bare soil areas while vegetation is establishing
Temporary check dams in drainage channels and swales to slow water flow and reduce sediment transport

One of the biggest advantages of coir logs is that they’re fully biodegradable — over time, the coconut fibre breaks down naturally, often while new vegetation grows directly through the log, helping to permanently stabilise the area they were installed to protect. This makes coir logs a preferred option where councils or environmental authorities require sediment control methods with minimal long-term environmental impact.
