Erosion Control Blanket (Coconut Blanket) | Coir Mat & Natural Fiber Erosion Control Mat

NK's erosion control blankets are made from high-quality natural coconut shell fiber from Southeast Asia. They are produced using a fully automated needle-punched composite production line through carding and needle-punching processes. These blankets can be combined with grass seeds and grids on demand to create ecological soil and water conservation materials.

Each batch undergoes testing for unit area quality, tensile strength, and grass seed germination rate (with grass seeds), strictly complying with the industry standard "Technical Regulations for Ecological Bank Protection Projects."

NK's erosion control blankets are not only used in domestic highway slope protection, river bank protection, and mine restoration projects, but are also exported to 18 countries and regions, including Japan, South Korea, Thailand, and South Africa. Their natural and environmentally friendly properties have earned them high recognition from ecological engineering projects.

Advantages & Strengths

Natural Soil Fixation & Erosion Resistance:

Coconut fiber interweaves to form a dense network that effectively intercepts surface runoff, dispersing the force of rainwater and preventing surface soil loss. The naturally rough surface of coconut fiber increases surface friction and slows water flow.

Customizable Functionality:

The non-grass seed type is suitable for temporary protection. The grass seed type allows for both protection and greening. Once the grass seeds germinate, they form a "blanket-grass-soil" composite protection system with the coconut fiber mat. The gridded type uses PP grids to enhance overall tensile strength, making it suitable for protection on steep slopes (slopes ≤ 60°).

Ecological Compatibility & Biodegradability:

Coconut shreds are a natural organic material that slowly degrades over 2-3 years, converting into organic matter to improve soil. The addition of grass seeds can quickly restore surface vegetation cover, preventing the long-term impact of artificial materials on the ecological environment.

Water Retention & Growth Promotion:

Coconut fiber has excellent water absorption and retention properties, locking in soil moisture and providing a moist environment for grass seed germination and plant growth. It is particularly suitable for ecological restoration in arid and semi-arid areas.

Lightweight & Convenient Construction:

The finished product weighs only 1.5-3kg/m² and is extremely flexible, allowing it to be directly laid on uneven surfaces (such as gravel slopes and gently sloping farmland). No large equipment is required, and a single person can cover an average daily construction area of over 80 square meters.

Popular Applications

Mine Reclamation Initial Protection:

Use a 15mm thick grass seed and grid type (PP grid 30×30mm, ryegrass + alfalfa mixed with grass seeds): Cover the exposed rock surface or the surface of the slag pile in the mine, first fix the loose surface soil with coconut fiber mats and grids, and then use the grass seeds to germinate to achieve initial vegetation recovery.

River/Canal Ecological Bank Protection:

Use "270g/㎡ without grass seeds and grid" or "12mm thick with grass seeds and no grid (reed seeds)": laid on the river bank in the water level fluctuation area to resist water erosion and protect the bank stability. The grass seed type can promote the growth of aquatic vegetation and improve the water ecology.

Municipal Green Slope:

Use the "10mm thick grass seed without grid type (cosmos + zinnia mixed grass seed)": It is used in the gentle slope areas of urban parks and municipal green belts to prevent soil erosion on the slopes, quickly form landscape greening, and enhance the urban ecological appearance.

Highway/Railway Slope Protection:

For gentle slopes (≤30°), use the 10mm thick grass seed and no grid type (bermudagrass seeds). For steep slopes (30°-60°), use the 360g thick grass seed and grid type (PP grid 20×20mm, alfalfa seeds). This type of grid is laid on the slope surface to prevent erosion by rainwater. The grass seed type can form a green protective slope.
