porous landscape fabric Manufacturers

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

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

The special breathable performance of stitched polyester cloth ensures the breathable performance of ground waterproof, so that the water vapor produced by the temperature change can be discharged immediately under the ground waterproof, and the bond of ground waterproof and datum is not prone to the harm of water vapor, so as to ensure the lasting service life of ground waterproof.

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 same geomembrane product can be used in different places, and different geomembrane products must be used in the same place.

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).
