1. Product Overview

Short-filament composite drainage board is a multifunctional geosynthetic material composed of an HDPE drainage board laminated with short-filament nonwoven geotextile. The dimpled HDPE sheet ensures efficient drainage, while the geotextile layer provides filtration, preventing soil and sediment from clogging the drainage system. This combination is widely used in underground waterproofing, retaining walls, and green roofing systems.

2. Product Features

• Integrated Drainage and Filtration: Combines excellent water drainage with effective soil filtration.
• Durable and Reliable: Made from high-strength HDPE and short-filament geotextile for long-term performance.
• Lightweight and Flexible: Easy to install and transport, reducing labor costs.
• Chemical and UV Resistance: Resists degradation from harsh environmental conditions and chemicals.
• Eco-Friendly: Non-toxic and recyclable material, safe for sustainable projects.
