Sodium Bentonite Geosynthetic Clay Liner Gcl Manufacturers

When overlapping adjacent composite geomembranes, first expose the geotextile at the joints, sew adjacent geotextiles to the bottom layer, and then fit the welding edges of the two membrane layers together. The width of the flap is 150mm.

Sew knit polyester cloth before application and waterproof layer, should check the current status of the roof at the grass-roots level to ensure that the roof with no moisture, no freezing, smooth and clean, no loose grain protrusion, even other blocking some impurities, waterproof system of the cohesive force for don't need the waterproof work must carry on the protection of areas, use brush, broom to clean up the surface dust, Or other loose attachment, for the corner, gap joints, water outlet, out of the pipeline need to apply waterproof system, the need for separate treatment work in advance, the use of a layer of basic coating to add appropriate size of stitched polyester cloth to add a layer of basic coating, Next, I will talk to you about the construction process of sewing polyester cloth to help you have a deeper understanding of sewing polyester cloth.

The structure of geomembrane connection includes connection, welding and vulcanization methods. The connection method used in specific engineering practices should be reasonably selected according to different anti-seepage requirements and the characteristics of the selected geomembrane.

1. Polyester non-woven fabric is the golden partner of drainage board, which can filter water and hold the soil layer. The colors are generally black, yellow, white, gray, etc. Minimum specifications: width; 2 meters, 100 meters long. 2. Polyester non-woven fabric products are non-woven geotextiles reinforced by polyester continuous filaments. The tensile strength is ≥8KNm, and the elongation is 40-60%, which fully meets the requirements of Jr/ To1g98 (Road Shigong Synthetic Material). The technical requirements for geotextiles in the application technical specifications).

The anti-seepage geomembrane plays an important role in the waterproof work of embankments and upright dams. Since the end of the last century, it has been widely used, especially in the waterproof work of granular formations.

Geomembrane can be divided into types of polymer materials. Geomembrane has excellent properties in terms of tensile resistance, aging resistance and corrosion resistance.
