Product Overview:
Our 3D Drainage Composite Net combines a rigid polymer core (polypropylene/PE) with thermally bonded nonwoven geotextiles to form an integrated drainage system. Engineered for rapid water collection, conveyance, and retention capacity in demanding geotechnical applications.
Key Features:
High-Flow Drainage Core: Tri-planar geonet structure maintains consistent void space (>95% porosity) under heavy loads
Integrated Filtration: Dual geotextile layers retain soil while allowing unimpeded water inflow
Exceptional Compression Resistance: Withstands up to 1000 kPa stress without significant flow reduction
Chemical & Biological Resilience: Inert polymer construction resists soil chemicals and root penetration
Structural Void Maintenance: Prevents soil intrusion that clogs traditional drainage systems
Primary Applications:
Landfill Systems: Leachate collection layers, landfill caps, and gas venting layers
Retaining Walls & Bridge Abutments: Relieves hydrostatic pressure behind structures
Green Roofs & Plaza Decks: Lightweight drainage layer for vegetative roofing systems
Sport Fields & Landscaping: Subsurface drainage for turf, athletic tracks, and garden terraces
Highway & Railway Embankments: Prevents water saturation in roadbeds and slopes
Tunnel & Underground Structures: Perimeter drainage for waterproofing membranes
Compliance:
Tested to ASTM D4716 (flow capacity), D6364 (compression), and ISO 12958 standards for hydraulic performance.
Engineered Drainage Efficiency:
This composite net delivers superior long-term drainage performance by combining filtration, flow capacity, and structural integrity—reducing installation time and lifecycle costs in critical water management projects.
