Before laying the composite geomembrane, it should go through the inspection of the excavation of the exhaust trench, and complete the finishing and leveling of the bottom and slope of the storage.

The construction process of waterproof geotextile, the substrate must be firm, flat, clean, free of dust, greasy, wax, release agent, etc. and other debris; if there are pores, cracks, unequal defects on the base surface, it must be repaired with cement mortar in advance For smoothing,

Nowadays, the demand for anti-seepage geomembrane in the sales market is particularly large.

Slope protection bag is made of polypropylene (PP) or polyester fiber (PET) made of double-sided ironing needle punched non-woven fabrics. Under the premise of fully considering the requirements of many disciplines such as material mechanics, hydraulics, biology, botany, etc.

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".

The selection of composite geomembrane should be considered from the fields of engineering application, economy, construction process characteristics and raw material characteristics.
