The Erosion Control Techmat CB400J is a biodegradable erosion control roll designed to provide immediate soil coverage on vulnerable slopes, drainage channels and exposed ground. Manufactured from untreated coir stitched between durable jute netting with cotton thread, it helps stabilise soil, reduce surface erosion and support vegetation establishment while naturally degrading over time.
The Erosion Control Techmat CB400J is a natural erosion control solution manufactured from approximately 350gsm untreated coir stitched between upper and lower jute netting using cotton thread. Designed for challenging environments, it provides reliable soil retention while creating favourable conditions for vegetation growth.
As an erosion control roll, it delivers full soil coverage when installed in accordance with recommended installation methods. The natural fibre construction gradually decomposes over a period of approximately 6–12 months, returning organic matter to the ground while allowing vegetation to establish and strengthen the surface.
- The erosion control techmat contains untreated coir enclosed within durable jute netting for dependable temporary soil protection.
- Provides effective erosion control across exposed ground where soil movement may impact project performance and vegetation establishment.
- Designed for use on slopes of 1:1.5, 1:1 or steeper where additional surface stabilisation is required.
- Natural fibre construction supports vegetation growth while gradually degrading into the surrounding environment.
- Suitable for projects requiring biodegradable erosion protection without introducing permanent synthetic materials.
The Erosion Control Techmat CB400J is commonly specified where temporary erosion control measures are required during the critical period before vegetation becomes fully established. By maintaining surface stability, the system helps reduce soil loss caused by rainfall, surface runoff and changing ground conditions.
This erosion control roll is particularly effective on steep embankments, drainage channels and areas exposed to fluctuating water levels. The blanket structure helps retain soil particles while creating a stable environment for seed germination and root development. As vegetation establishes, the need for artificial support reduces naturally.
Contractors, civil engineering teams and environmental projects frequently select erosion control systems that balance performance with sustainability. The natural coir and jute construction of this product provides dependable short-term protection while avoiding long-term synthetic residues in the ground.
Where erosion control is required around watercourses, drainage infrastructure or landscaped embankments, the CB400J offers a practical and environmentally conscious solution. Its biodegradable composition allows the product to fulfil its protective function before naturally breaking down as vegetation becomes self-sustaining.

The CB400J erosion control techmat has been developed for projects where natural, biodegradable surface protection is required. The product combines untreated coir fibres with jute netting and cotton stitching to create a temporary erosion control system capable of supporting vegetation establishment while protecting exposed soil.
- Approximately 350gsm untreated coir core.
- Top and bottom jute net construction.
- Cotton thread stitching throughout.
- Suitable for slopes of 1:1.5, 1:1 or steeper.
- Biodegradation period of approximately 6–12 months.
- Supplied in standard roll size of 2.4m x 50m.
During the early stages of a project, exposed soil can be vulnerable to erosion caused by rainfall, wind and surface water movement. The CB400J helps provide immediate surface coverage, reducing the risk of soil displacement until vegetation becomes established enough to provide long-term stability.
The product is particularly valuable where environmental considerations are important. As the blanket naturally decomposes, organic material is returned to the soil profile, helping create conditions that support healthy vegetation growth.
Typical users include civil engineering contractors, environmental consultants, infrastructure projects, landscaping contractors and land restoration specialists. The erosion control roll can be incorporated into new developments, remediation schemes and water management projects where temporary protection is required.
Because the product is manufactured entirely from natural materials, it integrates effectively into environmentally sensitive locations. This makes it suitable for projects where long-term synthetic products are not desirable and where natural vegetation establishment is the ultimate objective.

What is the Erosion Control Techmat CB400J used for?
The Erosion Control Techmat CB400J is used for erosion control on slopes, drainage ditches, shorelines and other exposed ground where temporary soil stabilisation is required.
How long does this erosion control roll last?
The natural fibre construction is designed to break down over approximately 6–12 months, allowing vegetation to establish while providing temporary erosion protection.
Can the erosion control techmat be used near water?
Yes. The product is commonly used for shore and bank protection as well as areas experiencing rising and falling water levels.
What materials are used in the erosion control roll?
The blanket consists of untreated coir fibres stitched between upper and lower jute netting using cotton thread, creating a fully natural erosion control solution.
