Eco-friendly solutions for erosion control and natural stabilisation

Bio-Engineering provides natural shoreline stabilisation techniques that can effectively reduce erosion of exposed soil, sand and other sediments from wind and waves. It also helps to redress overland runoff, while providing storm damage protection to landward areas. The technology aids stabilisation of roads, slopes, riverbanks and highways prone to damages of erosion through natural or other causes.

The Bio-Engineering sector of Hayleys Fibre specialises in providing a range of long-term solutions, through the use of natural coconut fibre products. Coconut fibre has high lignin and low cellulose content, adding to its durability and resilience.


Our innovative product range comprising both woven and non-woven erosion control geotextiles, is seeing a rising demand all over the world, given its natural, flexible fibre attributes. 

Our geotextiles are absorbent fabrics produced from coir fibre, used in association with soil erosion, having the ability to separate, filter, reinforce, protect or drain. These products include coir blankets, coir logs, coir pillows and coir sandbags.

They provide solutions for soil loss, which affects soil and plant dynamics by preventing evaporation of soil moisture. The fabrics help to mitigate the loss of soil moisture that can adversely impact soil health, land surface ecosystems and managed systems, such as those in agriculture.

Geotextiles are used on non-vegetated portions of banks, to prevent erosion and support the growth of vegetation. Vegetation is established through a seed mix spread across the affected area, prior to the geotextile being secured. Then vegetation is planted through the blanket, which helps to hold sand, soil and other sediments in place. This provides a protective cover for the surface from erosion. In addition, it helps to retain moisture to protect seed growth and the roots of the plant. As the natural fibre in the blanket disintegrates, the dense root system of the plants helps to stabilise the area.

Coir Geotextiles (Woven)

Our range of woven erosion control geotextiles helps to enhance and restore the capacity of coastal banks, and protects elevated areas from bank erosion, which occurs as a result of the detachment of bank soil. 

These products, in conjunction with other techniques for erosion management, can help preserve the natural character and habitat value of the coastal environment. They also support the restoration capacity of coastal banks to protect upland areas from erosion, and maintain habitat and ecosystem function for coastal species.

Coir Yarn Geotextiles

Coir yarn geotextiles are natural handwoven products used for short-term erosion control problems. They can be woven into varying mesh sizes and used in surface erosion control, such as on construction sites when made into silt fencing.

Coir Twine Geotextiles

Coir twine geotextiles are machine-spun and applied for long-term erosion control problems. Lasting between five to six years, by which time the required vegetation is well established, its high tensile strength enables it to handle more physically demanding conditions such as steep slopes and fast-flowing streams.

Product application and usages:

Coir Logs, Pillows and Interlocking Blocks

Our bio-degradable, easy-to-install and use product range, which includes coir logs, pillows and interlocking blocks, provide the ultimate solution for erosion control and shoreline protection. Each product is designed to provide soil stabilisation and support, and offers a high level of strength and reinforcement. They make for ideal erosion control in restoration projects, environmentally sensitive zones, stabilisation areas and construction sites.

Coir Logs

Coir logs can be installed to stabilise the banks of ponds, streams, lakes and rivers, or waterways affected by contaminated shore waters, to protect them from further erosion. They are manufactured with machine-spun coir yarn netting or synthetic netting, with the inner layer filled with coir mattress fibre. Customised logs can be made with “vegetation holes” to hold plants, and shapes can be either cylindrical or square.

Coir Pillows

Coir pillows are made with a thick layer of coir fibre filled into a coir bag, which is typically made of geotextiles. Packing is in loosely pressed bundles or in rolls, and has been designed to facilitate vegetation and erosion control applications. Especially for floating gardens, roof greening applications, wetland creation, establishing vegetation on banks. 100% natural and biodegradable, similar to coir logs, coir pillows can be customised to any size.

Coir Blocks

Coir blocks are made from ground coir and compressed into a block form, for usage in diverse erosion control applications. This method helps to eliminate complex and expensive construction techniques. The three-dimensional structure enables an ‘H’ shape of cells on the slope, which provides an interlocking arrangement.

The coir block can be filled with growing media suitable for the establishment of vegetation. These blocks greatly improve erosion run-off on steep or unstable slopes, while strengthening it against erosion from water, hydraulic or mechanical stresses. Blocks can be joined to support soil stretches of any length, used to add heights to shorelines or in landscaping. They are also ideal for restoring environmentally sensitive areas, by providing soil enrichment and stabilisation solutions, and controlling runoffs at construction sites.

Product application and usages:

Erosion Control Blankets (Non-Woven Coir Geotextiles)

Erosion control blankets provide temporary cover and support for establishing vegetation on bare soil areas and support for emergent vegetation. From seeding to top growth, its capable of long term erosion protection, shielding bare soil and newly seeded areas against raindrops and wind erosion. It facilities vegetation on different slope types (low, moderate and steep). Designed and fabricated to different periods of time, based on functional longevity, it later decomposes to further aid in plant growth. Customised solutions can be provided, in consideration of the affected area.

Manufactured from coconut fibre, straw fibre or a blend of both, non-woven erosion control blankets are sewn with 100% organic mesh made of jute net and cotton thread. Alternatively, the blankets can be stitched with polypropylene thread and polypropylene mesh.

Product application and usages:

Currently, the blanket is popular as a method for turf growing/sedum, providing a base for the backing layer in turf grass lawns and sedum growing fields. It can also be used in roof greening projects.

Additional benefits of coir stitched blankets for sedum growers include:
