geomembrane liner pond Manufacturers

After the dam body is filled and the reservoir bottom is compacted to meet the design requirements, and the composite geomembrane impermeable body protective layer is prepared according to the design requirements, the construction technology of the composite geomembrane impermeable body is: the composite geomembrane is in place and the paving is straight → Butt joint, bottom fiber butt joint (stitching) → membrane material butt joint, hot melt pressure welding → inflation pressure (or negative pressure method) → surface fiber butt joint (sewing) → reserved capacity.

When selecting the anti-seepage geomembrane, we must first establish our ordering purpose, for which place and what function is required for ordering the geomembrane. Knowing this, we can reasonably and effectively reduce the selection category.

The placement process of HDPE geomembrane includes material cutting, test welding, welding equipment debugging, anchoring, inspection and acceptance, etc.

The selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction technology characteristics and material performance. First consider whether the permeability and quality meet the requirements. Secondly, in order to prevent damages encountered during transportation and construction, geomembrane must have good mechanical properties such as anti-permeation, anti-puncture, and tensile strength. Of course, during construction, we must also take care to protect it from damage. In addition to the above points, durability and thickness should also be considered.

The composite geomembrane is formed by heating one side or both sides of the film in the far-infrared drying box, and pressing the geotextile and the geomembrane together by means of guide rollers.
