Product Description

Product Description

Composite geomembrane is a three-layer geosynthetic material composed of two layers of polyester short fibers or filament geotextile and one layer of geomembrane. It has the characteristics of seepage prevention, isolation, sealing, high strength, anti-aging, acid and alkali resistance, abrasion resistance, good flexibility, etc,



Composite geotextile is an anti-seepage material composed of geotextiles and geotextiles. The minimum specification of the national standard is 400g per square meter, and the maximum weight is over 3000 grams. The conventional geotextile is short fiber nonwoven geotextile with the code SN. If the design code on the drawing is FN, it is long fiber nonwoven needle punched geotextile. The material of the geotextile is mostly polyethylene with the code PE, and it is rarely designed as polyvinyl chloride with the code PVC. Below, we will give an example.



SN2/PE-16-400-0.5 This code represents two layers of short fiber non-woven needle punched geotextile, PE represents polyethylene geotextile film, 400 represents the overall weight of the two layers of geotextile fabric of 400 grams, 0.5 represents the thickness of polyethylene geotextile film of 0.5 millimeters, and 16 represents the fracture strength of composite geotextile film of 16 kN/meter. The specific specification is 200g/0.5mm/200g two fabrics and one film. This is a universal formula, and different data can be applied.



Although composite geomembrane is a composite material, the four connecting edges need to be separated during production. During construction, membrane to membrane welding and fabric to fabric stitching are necessary to ensure the anti-seepage effect.

Installation Instructions

 

Composite geomembrane is a type of anti-seepage, waterproofing, and isolation material applied in various engineering fields. When installing composite geomembranes, the following steps need to be noted:

Preparation work: Before installing the composite geomembrane, a site investigation should be conducted to ensure that the construction site is flat, clean, and free of debris and sharp objects. At the same time, understand the construction drawings and clarify the laying position and direction of the composite geomembrane.

Laying base treatment: The construction base should be treated to ensure that it is flat, solid, and free from cracks, hollowing, and other phenomena. If the base is soil, it should be compacted; If the base is made of concrete, its surface should be ensured to be flat and clean.

Laying method:

Firstly, lay the composite geomembrane flat on the substrate, ensuring that the direction of membrane installation is consistent with the direction of water flow.

Then, use specialized adhesive to firmly bond the composite geotextile film to the substrate. The glue should be evenly applied on the back of the film, with a thickness of approximately 1 millimeter.

Finally, use a roller or scraper to flatten the composite geomembrane, ensuring a tight adhesion between the membrane and the substrate.

Joint treatment: The joints of the composite geomembrane should be welded using a hot melt welding machine to ensure that the joints are firm and sealed. When welding, clean the joints first, and then perform hot melt welding. During the welding process, it is necessary to ensure that the weld seam is neat, without any false or missed welds.

Inspection and acceptance: After installation is completed, the composite geotextile shall be inspected to ensure that the construction quality meets the requirements. The inspection content includes: the direction of membrane laying, joint treatment, and the adhesion between the membrane and the substrate. If any problems are found, they should be rectified in a timely manner.

Construction safety: During the installation of composite geomembranes, construction personnel should wear labor protection equipment to ensure construction safety. Meanwhile, avoid construction under adverse weather conditions.

In short, when installing composite geomembranes, strict adherence to construction drawings and specifications should be followed to ensure construction quality. At the same time, pay attention to construction safety and environmental protection.
