Joint and overlap of Tri-dimension composite geonet for drainage

Joint and overlap of Tri-dimension composite geonet for drainage

1. The position of the geosynthetic material should be adjusted so that the length of the material roll is perpendicular to the road.

2. The composite geo-drainage network must be terminated, and the geotextiles on the adjacent geonet cores should be lapped along the material roll.

3. Connect the geonet cores of adjacent geomaterial rolls with white or yellow plastic buckles or polymer straps to connect the rolls. Along the length of the material roll, connect with a tape every 3 feet.

4. The direction of the lapped geotextile should be consistent with the direction of the packing. If the geotextile is laid between the foundation / base and the subbase, continuous wedge welding, flat-head welding or stitching shall be carried out to fix the overlapping geotextile upper layer. If stitching, it is recommended to use flat-head stitching or general stitching to meet the lower limit of stitch length.
