Water storage and drainage board in landscaping works
Water storage/drainage boards are innovative geosynthetic materials designed for modern landscaping projects. These lightweight yet durable panels, typically made from HDPE or PP, combine water management and structural support functions in a single solution.
Advantages and Functions of Water Storage/Drainage Boards in Landscaping Engineering
Advantages
Efficient Water Management
Balances water retention and drainage, preventing both waterlogging and drought.
Lightweight & Easy Installation
Made of durable yet lightweight materials (HDPE/PP), reducing construction costs.
Root Protection
Prevents root rot by maintaining optimal soil moisture.
Space Optimization
Replaces traditional gravel layers, increasing usable green space.
Durability
Resists corrosion, UV radiation, and compression (load capacity: 100-500 kN/m²).
Functions
Drainage
Rapidly removes excess water through designed channels (drainage capacity: 5-10 L/m²·s).
Water Storage
Stores water in cavities for gradual release during dry periods.
Aeration
Improves soil oxygen circulation to promote root health.
Load Distribution
Evenly distributes pressure from pedestrian/vehicle traffic (e.g., rooftop gardens).
Erosion Control
Stabilizes soil structure to prevent nutrient loss.
Typical Applications
Rooftop Gardens
Urban Rain Gardens
Sports Fields
Slope Greening
Technical Note: Combined with geotextiles, drainage boards can achieve filtration and anti-clogging effects.
With their multifunctional design and long service life, water storage/drainage boards offer a cost-effective, sustainable solution for modern green infrastructure projects. Their versatility makes them particularly valuable in urban environments where space optimization and efficient water management are crucial.
