Introduction to 300g Two Cloth One Membrane Waterproof Geotextile in Beijing

Description :

　　1、 Performance characteristics of 300g waterproof geotextile in Beijing:

　　Good flexibility, in addition to the anti-aging, high strength, good flexibility, and isolation properties of geotextiles, it also has a sealing (anti-seepage) function.

　　2、 The purpose and function of Beijing 300g two cloth one membrane waterproof geotextile:

　　Widely used in many fields such as water conservancy, dams, tunnels, road construction, airports, etc., it mainly plays a role in waterproofing, anti-seepage, protection, reinforcement, leakage prevention, isolation, etc. in engineering.

　　4、 Construction requirements for 300g waterproof geotextile with two fabrics and one membrane in Beijing:

　　1. The use should be buried, and the covering thickness should not be less than 30cm

　　2. The entire anti-seepage system is composed of a cushion layer, anti-seepage layer, transition layer, and protective layer.

　　3. The soil should be solid, avoiding uneven settlement, cracks, and removing grass and tree roots within the anti-seepage range. Lay a protective layer of sand or clay with small particle size on the contact surface with the membrane.

　　4. When laying, do not pull the geomembrane too tightly. It is better to embed the soil at both ends in a corrugated shape, especially when anchoring with rigid materials, leaving a certain amount of expansion and contraction.

　　5. During construction, stones and heavy objects should be avoided from directly hitting the geomembrane. The construction should be carried out while laying the membrane and covering the protective layer.

　　Beijing 300g Two Cloth and One Film Waterproof Geotextile Product Introduction:

　　Laying by burying method; Geotextile serves as a protective layer for geomembrane, preventing damage to the anti-seepage layer. To reduce ultraviolet radiation and increase anti-aging performance.

　　During construction, it is necessary to use sand or clay with smaller diameters to level the base surface before laying. When laying, do not tighten too tightly, and the two ends should be buried in the soil in a corrugated shape. A layer of about 10cm transition layer should be laid with fine sand or clay on the two fabrics and one film with a weight of 300g. Build 20-30cm stone blocks (or precast concrete blocks) as a protective layer against erosion. During construction, efforts should be made to avoid stones directly hitting the surface, and protective layer construction should be carried out while laying the film.

　　The connection between Beijing 300g two cloth one film and surrounding structures should be anchored with expansion bolts and steel plate pressure strips. The connection area should be coated with emulsified asphalt (2mm thick) for bonding to prevent leakage. Construction joint treatment is a process that directly affects the anti-seepage effect. The general joint methods include: ① overlap: the overlap width should be greater than 15cm; ② hot welding: suitable for slightly thicker geomembrane substrates, with a weld overlap width of not less than 5CM
