HGM50T is a typical product used in landfill and mining applications. Single or double textured geomembrane liner has a rough surface which improve the friction coefficient. It fits more suitable for steep slope and vertical engineering design work which maximize the effective volume of geomembrane. Compared with smooth geomembrane liner, it has better UV and puncture resistance.

- The seaming will be done vertically on the slope.
- The number of seams will be minimized on corners or odd-shapes. A maximum of 3 rolls can be welded together (using a T-joint configuration).
- No horizontal seams near the bottom of a slope or any high stress concentration.
- To assist with vertical welding, panels are visibly marked with a line 140 mm from the outside edge of the material. With a double wedge weld, the overlap should be wider than the weld by at least 10 mm, and 50 mm with an extrusion weld.
- The overlaps must be dry and clear when welding begins.
- Trial seams are done at the beginning, middle and the end of each seaming period. The trial seams must always be done under the same conditions as the geomembrane seam is done. The trial seams must be 1 m in length and 0.3 in width.
- Using a field tensiometer, 5 welding samples will be done. The samples will be 2.5 cm wide and 30 cm long. If any of the samples fail – the entire operation will have to be repeated.
- If excessive wrinkling occurs (fish mouths) then the edges of the wrinkling is cut in order to create a flat overlap. The places that were cut will then be seamed. If the cutting caused an issue with the length of the overlap than a round or oval patch will be placed that must extend 15 cm from all sides.
