Geocomposites Mac Drain Manufacturers

The composite geomembrane is strong in adapting to the new environment and has excellent chemical and physical properties.

The geomembrane is damaged during transportation and on-site construction, which changes the destruction mechanism of the geomembrane and affects its anti-permeability and stress performance. The composite geomembrane uses hot melt technology to bond the membrane to the cloth. The bilateral geotextile can effectively protect the geomembrane from damage. However, in the process of manufacturing and building connection, hot melt technology will inevitably cause thermal burns and defects of the soil membrane, which has the hidden danger of preventing penetration.

Do you know? As the name suggests, geotextiles are industrial "cloths" formed by weaving and synthetic fibers. They are generally divided into woven and non-woven fabrics. Textile means that the raw materials are woven by traditional machines. Non-woven fabric refers to the bonding of raw materials into a cloth shape by thermal melting or other physical methods. The most common wet wipes use non-woven materials. Geomembrane is similar to plastic bags that are common in life. The main material is polyethylene and EVA (ethylene acetic acid copolymer), the same as the usual plastic bags. Different thicknesses are used to distinguish specifications. When the thickness exceeds 0.8mm, it is called "geoboard".

High-density HDPE composite geomembrane is a waterproof raw material made of geotextile and geomembrane composite materials.

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.

The geomembrane at the bottom of the reservoir can be laid after excavation and filling of the dam in the reservoir area.
