Product Features of 3D Composite Drainage Geonet:
1. High drainage capacity; capable of withstanding long-term high-pressure loads;
2. Extremely high tensile and shear strength;
3. Minimizes the risk of geotextile embedding into the geonet core, ensuring stable long-term hydraulic conductivity;
4. Capable of withstanding compressive loads exceeding 2000 kPa;
5. Compressive strength far superior to that of standard drainage geonets.
Product Specifications of 3D Composite Drainage Geonet:
1. At a load of 720 kPa and a gradient of 2%: permeability is 2500 m/d; flow rate is 13 L/(m·min).
2. Creep test: retains over 60% of its thickness after 10,000 hours under a 1200 kPa load.
3. Tri-rib geonet core: carbon black content ≥ 2%; density 0.94 g/cm³; tensile strength ≥ 36.5 kN/m; melt flow index 1.0 g/10 min; thickness 7.6 mm.
4. Non-woven geotextile: apparent opening size 0.18 mm; water permeability 0.26 sec⁻¹; permeability coefficient 0.2 cm/sec; puncture strength 580 N; trapezoidal tear strength 356 N; grab tensile strength 900 N; grab elongation 50%; burst strength 2750 kPa.
Product Applications of 3D Composite Drainage Geonet:
Primarily used in landfills, roadbeds, and tunnel linings.
Installation Method for 3D Composite Drainage Geonet:
1. Orient the geosynthetic material so that the length of the roll runs perpendicular to the roadway.
2. The composite drainage geonets must be butt-jointed; the geotextile layers on adjacent geonet cores should overlap along the length of the rolls.
3. Connect the geonet cores of adjacent rolls using white or yellow plastic fasteners or polymer straps to secure the rolls together. Secure the material rolls with straps at 3-foot intervals along their length.
4. The direction of the overlapping geotextiles must align with the direction of fill placement. If the geotextile is laid between the subgrade/base and the sub-base, the upper layer of the overlap must be secured via continuous wedge welding, butt welding, or sewing. If sewing is used, a butt-seam or standard seam method is recommended to meet the required stitch length specifications.
