Biodegradable Plant Fiber Ecological Blind Drain

Product features:

The core is made from compressed hemp fiber and coconut coir, which are renewable, biodegradable agricultural waste products, reducing reliance on virgin plastic or concrete materials. The microbial degradable starch binding agent breaks down without releasing harmful chemicals, ensuring the product leaves no toxic residue in the soil. The 8mm aperture size filters out fine soil particles while allowing water to flow freely, preventing clogging and improving water clarity in drainage outflow. Unlike traditional drainage products, this blind drain does not require geotextile wrapping or gravel backfill, reducing installation costs and minimizing disturbance to the local soil ecosystem. After degradation, the remaining fiber material adds organic matter to the soil, supporting the growth of native plants and improving soil health.

Product specifications:

Each roll comes in 50 linear meter lengths, with a core diameter of 90mm. The compressed fiber core has an 8mm aperture size, with a drainage flow rate of 90 liters per hour per linear meter. The compressive strength is 120 kPa, allowing it to support light foot traffic and shallow root growth from native plants. The operating temperature range spans from 0°C to 60°C, making it suitable for temperate and subtropical ecological restoration projects. The product biodegrades by 90% within 5 years when buried in soil, and it meets EU Ecolabel and OK Compost certification standards for fully compostable products. Installation requires only a shallow 15cm-deep trench, with no additional backfill materials needed.

Product application:

Primary applications include wetland restoration and water quality improvement, riparian zone and stream bank drainage, native plant garden and ecological park drainage, and contaminated soil runoff filtration. It is also suitable for use in organic wetland farms and ecological education reserve projects. The product is ideal for environmental restoration organizations, eco-friendly developers, and government conservation agencies looking to implement sustainable drainage solutions that support local ecosystem health while solving water management issues.
