Drainage material "Public Drain"

Core structure with excellent pressure resistance! Drainage material that maintains high drainage capacity over a long period.

"Public Drain" is a new drainage material that maintains high drainage capacity, replacing sand and gravel. It can be used in various applications, including internal drainage of embankments and backfill drainage for general structures. Both the filter and core material are highly strong and flexible, allowing them to adapt to ground changes, eliminating concerns about breakage or cutting. No special techniques or joints are required, and its lightweight nature increases construction speed. Additionally, costs are reduced to 1/2 to 1/5 compared to conventional methods using natural aggregates. 【Features】 - High drainage capacity - High-performance dual-sided drainage type - Adapts to ground deformation - Easy installation and excellent cost-effectiveness For more details, please contact us.
