High drainage efficiency: Convex nubs enable rapid water flow to prevent waterlogging.
Lightweight design: Easy to handle and install, reducing labor and construction time.
Strong compressive resistance: Withstands heavy soil loads without deformation.
Integrated filtration: Optional geotextile layers block soil particles to avoid clogging.
Introduction:
Crafted from premium polypropylene (PP), this drainage board features a lightweight yet robust structure with evenly spaced convex nubs or channels. The material’s high crystallinity ensures rigidity and chemical resistance, while the innovative design optimizes water flow and soil stability.
Key Physical Features
Convex Nub Design: Creates a 3D space for efficient water collection and drainage.
