Drainage Board is a geosynthetic material engineered to provide efficient water drainage, soil stabilization, and structural protection in construction, landscaping, and environmental projects. Made from high-density polyethylene (HDPE) or polypropylene (PP), it features a three-dimensional core structure paired with a geotextile filtration layer, ensuring rapid water removal while preventing soil erosion and hydrostatic pressure buildup.
1. Durable Material Composition
Core Layer: Rigid HDPE/PP matrix with raised studs or dimples (height: 8–50 mm) for high compressive strength (≥300 kPa).
Geotextile Filter: Non-woven polyester or polypropylene fabric (100–500 g/m²) to block soil particles while allowing water flow.
2. Superior Drainage Performance
Rapidly channels water away from structures, achieving a drainage capacity
Reduces hydrostatic pressure on foundations, walls, and retaining structures.
3. Lightweight & Flexible
Easy to cut and install on slopes, curved surfaces, or irregular terrains.
UV-resistant and chemical-proof for long-term outdoor use (lifespan: 10–20 years).
4. Multi-Functional Design
Acts as a protective barrier against root penetration and mechanical damage.
Compatible with vegetation for eco-friendly slope greening.
