Storage & Drainage Board – The Ideal Solution for Green Roofs and Landscape Drainage

In modern construction and ecological engineering, effective water management is critical for structural integrity and vegetation health. The storage and drainage board is a high-performance geosynthetic material that combines drainage and water retention functions in a single lightweight panel. Made from high-density polyethylene (HDPE) or polypropylene (PP) through a thermocompression molding process, this innovative product features a concave-convex structural design that creates stable drainage channels while storing excess water for plant use during dry periods.

1. Key Features & Benefits

Storage and drainage boards offer numerous advantages over traditional drainage methods:

Dual Functionality Simultaneously drains excess water and retains moisture for plant growth, with a storage capacity of approximately 4 kg per square meter.
High Compressive Strength Withstands over 400 kPa of load, and can endure mechanical compaction during backfilling operations.
Excellent Durability Resistant to root penetration, chemical corrosion, and extreme temperatures (no cracking at -25°C).
Lightweight & Easy Installation Reduces structural loads, simplifies transport, and enables quick, labor-efficient installation.
Thermal Insulation The hollow structure provides effective thermal insulation, reducing indoor temperature fluctuations.
Cost-Effective Replaces traditional gravel and pebble drainage layers, saving time, labor, and material costs while reducing building loads.

2. Main Application Areas

This versatile material is widely used across multiple sectors:

• Green Roofs & Rooftop Gardens
Provides drainage, water storage, root barrier, and thermal insulation.
• Underground Parking Deck Greening
Protects waterproofing layers while supporting vegetation.
• Landscape & Municipal Projects
Used in city squares, parks, golf courses, and sports fields.
• Building Construction
Applied on foundation slabs and basement walls.
• Transportation Infrastructure
Used in highway and railway subgrades and embankments.
• Hydraulic Engineering
Suitable for dams, reservoirs, and drainage systems.
