When overlapping with the adjacent composite geomembrane, first expose the geotextile at the joints, sew the adjacent geotextile of the lower layer, adjust the welding edge of the two membrane layers, and weld the middle of the composite geomembrane with an overlap width of 150mm body.
High-density polyethylene (HDPE) composite geomembrane is a non-polar thermoplastic synthetic material with high impermeability, corrosion resistance and stable chemical properties.
Geomembrane can be divided into types of polymer materials. Geomembrane has excellent properties in terms of tensile resistance, aging resistance and corrosion resistance.
The selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction technology characteristics and material performance.
After laying and connecting the composite geomembrane, immediately (within 48 hours) backfill the sand gravel or earth material protective layer.
In order to ensure the smooth progress of construction, all employees involved in the purchase of geomembrane must be made aware of the use of geomembrane parameters.
