COMPOSITE DRAINAGE GEONET
Composite Drainage Geonet
A three-dimensional plastic mesh core with geotextile bonded on both sides, developed for drainage requirements in railways, highways, tunnels, municipal works, reservoirs and slope-protection applications.
PRODUCT OVERVIEW
A Layered Geosynthetic for Project Drainage
Composite Drainage Geonet combines a three-dimensional plastic mesh core with geotextile bonded to both faces. The layered construction provides a geosynthetic drainage component for project-specific drainage systems.
Core thickness, roll width and project-designed length should be selected in relation to the application, drainage design and project documentation requirements.
THREE-LAYER STRUCTURE
Geotextile Bonded to Both Sides of a Three-Dimensional Core
The product structure is formed by double-sided bonding of geotextile to a three-dimensional plastic mesh core.
Upper Geotextile Layer
One geotextile face is bonded to the upper side of the mesh core.
Three-Dimensional Plastic Mesh Core
The central plastic mesh core is available in a stated thickness range of 3–8 mm.
Lower Geotextile Layer
A second geotextile face is bonded to the opposite side of the mesh core.
