Product Description
High-Efficiency Composite Drainage Geonet
Fast drainage solution for landfill and tunnel projects with integrated filtration and reinforcement capabilities.
Product Overview
Composite Drainage Geonet is an integrated composite drainage material composed of a three-dimensional HDPE geonet core with upper and lower layers of non-woven geotextiles. This design combines drainage, filtration, and reinforcement functions in a single solution.
Key Features
- Excellent drainage efficiency for rapid water discharge
- Prevents water accumulation and erosion
- Integrated filtration system intercepts soil particles
- Reinforcement capabilities for structural stability
- Ideal for projects requiring fast drainage solutions
Manufacturing Process
Advanced composite production technology ensures optimal performance. High-density polyethylene (HDPE) is extruded into a three-dimensional network core with vertical ribs and inclined supports, creating continuous drainage channels. Upper and lower layers of polypropylene non-woven geotextiles are hot-melt bonded to the geonet core, providing secure composite bonding and maintaining unobstructed drainage channels while effectively intercepting soil particles.
