3D Composite Drainage Net Rapid Water Removal, Unmatched Stability

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.

Founded in 2008, Jianyi group  is a large production base of solid waste safe landfill and engineering protective materials in China. The company has participated in the major infrastructure construction of the country and the "the Belt and Road", the construction of emergency epidemic prevention projects in Wuhan Huoshen mountain, Leishen mountain and Guangzhou Eighth People's Hospital, the national strategy for special treatment of heavy metals, the landfill and incineration of urban domestic waste, industrial waste, hazardous waste disposal and other environmental protection projects, provided a large number of high-quality new geotechnical environmental protection materials for the partners, and provided overall solutions for the project.
