It is made of 100% renewable bio-based raw materials, and the filter layer uses degradable nonwoven fabric without subsequent recycling treatment. It will not release toxic substances during the degradation process. The flexible structure is suitable for installation on irregular terrains, and its water permeability meets the drainage requirements of small and medium-sized scenarios. Its weight is only 60% of HDPE blind drains, reducing transportation and construction costs, making it ideal for temporary engineering use.
It has an outer diameter of 80mm, inner diameter of 55mm, perforated diameter of 8mm with spacing of 60mm, standard length of 30m per roll, material thickness of 2mm, water permeability of ≥70L/(m·h), compression strength of 150kPa, operating temperature range of -10℃ to 50℃, complies with OK Compost certification, has a soil degradation cycle of 2-3 years, and weighs approximately 1.3kg per meter.
It is suitable for drainage of temporary construction sites, drainage of wetland ecological restoration projects, drainage of urban temporary event venues, and underground seepage treatment in ecologically sensitive areas. It can be directly buried in soil without recycling, and will degrade into part of soil organic matter after use.
