Rigid Plastic Modular Municipal Blind Drain

Product features:

The recycled PVC rigid core is fully recyclable at the end of its service life, aligning with urban sustainable development goals. The honeycomb grid design creates multiple drainage channels, ensuring consistent flow even when partially clogged, and the self-cleaning surface prevents fine soil particles from adhering to the aperture, reducing maintenance frequency by 60% compared to traditional blind drains. The tool-free snap-lock joints eliminate the need for specialized welding equipment, allowing unskilled construction workers to install the product quickly, which is critical for road repair projects with tight time constraints. It also features high temperature resistance, making it suitable for arctic and tropical urban environments, and meets European and international standard drainage product certifications.

Product specifications:

Each coil comes in 20 linear meter lengths, with an outer width of 150mm and a height of 80mm. The honeycomb core has 15mm square apertures, with a total drainage flow rate of 180 liters per hour per linear meter. The compressive strength is 400 kPa, allowing it to support 40 metric tons of vertical load per square meter, making it suitable for highway shoulders, parking lots, and heavy traffic urban roads. The operating temperature range spans from -30°C to 90°C, and the product is resistant to road salt, oil, and other urban chemical contaminants. Installation requires a 40cm-deep trench with a geotextile layer beneath the core to prevent soil migration into the drainage channels.

Product application:

Primary applications include highway and urban road subsurface drainage, basement and underground garage waterproof drainage, public park and green space soil moisture management, and railway track side drainage. It is also suitable for airport runway edge drainage and industrial warehouse floor drainage. The product is ideal for municipal engineering contractors, road construction companies, and urban infrastructure development projects, providing a reliable, low-maintenance drainage solution for high-traffic urban areas.
