Product Details
A drainage board is a lightweight, durable geosynthetic material designed to facilitate water drainage, protect waterproofing layers, and enhance soil stability. It is commonly used in underground structures, green roofs, roadways, and landscaping applications. Drainage boards are typically made from HDPE (high-density polyethylene), PP (polypropylene), or other polymeric materials and feature a dimpled or grid-like structure that creates voids for efficient water flow.
Characteristics of Drainage Boards
1. High Drainage Efficiency
• Designed with dimpled or channeled structures to quickly channel water away from surfaces.
• Reduces hydrostatic pressure and prevents waterlogging in structures and soil.
2. Durable and Long-Lasting
• Made from high-strength, weather-resistant polymer materials (HDPE, PP) that withstand pressure, chemical exposure, and environmental conditions.
• Resistant to rot, corrosion, and biological degradation.
3. Lightweight and Easy to Install
• Compared to traditional drainage materials like gravel, drainage boards are lightweight and easy to handle, reducing labor costs.
• Simple installation process using rolls or sheets that can be cut to fit various applications.
4. Versatile Applications
• Suitable for a wide range of construction and landscaping projects, from green roofs to heavy-duty infrastructure.
• Compatible with waterproof membranes, geotextiles, and other drainage systems.
5. Environmental Benefits
• Reduces reliance on gravel-based drainage systems, lowering excavation and transportation-related carbon footprints.
• Some drainage boards are made from recycled materials, promoting sustainability in construction.
Features
Underground Structures (Basements, Tunnels, Underground Parking Lots)
• Waterproofing Protection: Placed over waterproof membranes, drainage boards prevent hydrostatic pressure buildup, extending the lifespan of waterproofing systems.
• Efficient Drainage: Channels water away from structures, preventing water seepage into basements and tunnels.
Green Roofs and Landscaping
• Water Retention & Drainage Balance: Allows excess water to drain while retaining enough moisture to support plant growth.
• Prevention of Root Rot: Ensures proper aeration of plant roots by preventing waterlogging.
Road and Railway Construction
• Subsurface Drainage Improvement: Reduces water accumulation under roads and railways, minimizing soil erosion and pavement damage.
• Prevention of Frost Heave: Helps drain excess water, reducing the risk of frost-induced road damage in cold climates.
Retaining Walls and Slope Protection
• Lateral Pressure Reduction: Prevents water buildup behind retaining walls, reducing hydrostatic pressure and improving structural stability.
• Enhanced Soil Stability: Facilitates water drainage in sloped areas, preventing landslides and soil erosion.
Sports Fields and Golf Courses
• Rapid Water Drainage: Maintains optimal field conditions by efficiently draining rainwater, preventing muddy or waterlogged surfaces.
• Improved Playing Surface Durability: Reduces soil compaction, extending the lifespan of sports turf and golf courses.
