Product Description
Plastic Drainage Board is a highly engineered vertical drainage solution widely used in soft soil consolidation projects. Manufactured from high-quality HDPE or PVC materials, the board features a structured core with longitudinal channels that efficiently transport water under pressure conditions.
Compared with traditional sand drains or gravel layers, this product offers faster drainage paths, reduced settlement time, and significantly lower construction cost. Its lightweight structure allows rapid installation with minimal disturbance to soil layers, making it especially suitable for large-scale infrastructure such as highways, ports, and reclamation projects.
The optimized rib structure ensures high compressive resistance while maintaining consistent water flow even under heavy loads. This makes it a reliable choice for long-term drainage performance in demanding geotechnical environments.
