In both gardens and commercial projects, one problem which greatly impedes progress is land erosion. The erosion of lands, such as soil and sand, can result in both hefty financial costs and labour costs.
However, there is one very effective means of dealing with land erosion: coir matting. Coir matting is a sheet of woven coconut fibre that is designed to bring strength and structure to loose sand and soil.
As well as providing strength, coir matting has many other environmental benefits that make it a standout choice for erosion control. Understanding these benefits can help you make the right decision for your next project.
Coir matting works by creating a protective barrier over vulnerable soil and sand surfaces. The woven coconut fibres interlock to form a stable matrix that holds soil particles in place, even during heavy rainfall or wind exposure.
This natural binding effect prevents topsoil from washing away on slopes and embankments. The matting also slows water runoff, allowing moisture to penetrate the soil rather than carrying it away. On steeper terrain, coir matting is one of several approaches covered in our guide to stabilising a steep bank.
Key erosion control features include:
For standard residential applications, this 400gsm matting roll provides excellent coverage for garden beds and moderate slopes where lighter erosion control is needed. For steeper commercial embankments or high-traffic areas, the heavier 900gsm version offers superior durability and longer-lasting protection against aggressive erosion.
As well as providing strength and shape to loose earth and sand, coir matting is also used to promote the growth of new plants that are added alongside it. As coir matting is made up entirely of coconut fibre, it integrates easily into any environment, which results in no environmental damage.
Coir matting also provides support for the root systems of plants, meaning that they can grow upon slopes that they wouldn't normally be able to grow on. As a result, coir matting is often used to restore the presence of plant life in sloped areas.
The matting creates ideal germination conditions by maintaining consistent soil temperature and protecting seeds from being displaced. Young seedlings benefit from the sheltered microclimate beneath the fibres, which shields them from harsh sun and wind.
Plant growth benefits include:
Coir matting can also be used to keep weeds away from your plants, further promoting their growth. The dense weave blocks light from reaching weed seeds while allowing your planted vegetation to grow through the matrix.
If you find that your soil is having difficulties holding moisture, coir matting is an effective way to help your soil retain moisture and keep your plants hydrated. This is because coconut fibre used in landscaping is naturally absorbent and maintains its condition even after prolonged exposure to moisture.
Coir fibres can absorb up to eight times their weight in water, creating a reservoir that gradually releases moisture back to the soil. This buffering effect is particularly valuable during dry spells when unprotected soil would quickly lose moisture to evaporation.
The matting also reduces surface evaporation by shading the soil and breaking up wind patterns that accelerate moisture loss. This means your plants require less frequent watering, saving both time and water resources.
Moisture management advantages:
This means that coir matting can often last up to five years without needing to be removed or replaced. The longevity of the product depends on local climate conditions, with matting in tropical areas breaking down faster than in temperate zones.
Another great benefit of coir matting is how beneficial it is to the environment. Coir matting is entirely biodegradable, meaning that it doesn't remain to damage the environment after it's done its job.
This is one of the things that sets coir matting above some other erosion control products, which are made of plastic that can remain as pollutants within the environment. Synthetic alternatives may be cheaper initially but create long-term waste management problems.
As the coir fibres gradually decompose, they add organic matter to the soil, improving its structure and fertility. This creates a positive feedback loop where the erosion control product actually enhances the growing environment rather than simply protecting it.
Environmental advantages compared to synthetic alternatives:
For larger erosion control needs along waterways or drainage lines, a 300mm diameter coir log provides substantial protection while maintaining the same environmental benefits as matting rolls. Where synthetic options like woven poly weed mat might be appropriate for permanent landscaping features, coir erosion control products excel in restoration projects where complete biodegradability is essential.
Proper installation is key to getting the full benefits from coir matting. While the process is straightforward, following the right steps ensures the matting performs effectively over its full lifespan.
The basic installation process involves:
For a complete walkthrough with detailed steps, see our guide on how to install coir matting. The NSW Government's erosion control guidelines recommend combining matting with additional anchoring on slopes steeper than 2:1 (H:V) or using heavier-weight products.
Selecting the appropriate coir product depends on your specific erosion control requirements. Different applications call for different densities, formats, and installation methods.
Matting rolls work best for broad surface coverage on slopes, embankments, and restoration areas. Coir rolls and logs are more suited to channel protection, shoreline stabilisation, and creating sediment barriers.
Consider these factors when choosing:
These are just some of the reasons as to why coir matting is one of the best erosion control products available today. Whether you need erosion control for a residential project or a large-scale commercial project, you can always find high-quality coir matting at All Stake Supply, one of Sydney's leaders in erosion control products.
Coir matting typically lasts between two and five years, depending on the weight of the matting and local climate conditions. Heavier grades such as 700gsm and above last longer, while matting in tropical or high-rainfall areas breaks down faster than in temperate zones. By the time the matting decomposes, the vegetation it supported should be well established.
Coir matting is made from coconut husk fibres and is more durable than jute, typically lasting two to five years compared to jute's one to two years. Coir is also more resistant to saltwater and moisture, making it better suited to coastal and waterway applications. For a detailed comparison, read about the differences between jute matting and coir matting.
Yes. Coir matting has an open weave that allows seeds to be broadcast directly over the top and germinate through the fibres. The matting protects seeds from being washed away by rain and creates a sheltered microclimate for germination.
For residential garden beds and gentle slopes, 400gsm coir matting provides adequate coverage. For steeper commercial embankments, construction sites, or high-flow drainage channels, 700gsm or 900gsm matting offers greater durability and erosion resistance.
Yes. Coir matting is 100% biodegradable and contains no synthetic materials, making it safe for use near creeks, rivers, and wetlands. According to the WA Department of Biodiversity, Conservation and Attractions, coir products are widely used in foreshore stabilisation and waterway rehabilitation projects across Australia.
Coir matting is secured using steel or biodegradable fastening pins driven through the matting into the soil at regular intervals. Pins should be placed roughly 300-500mm apart along edges and seams, with additional pins on steeper slopes.
