nonwoven fabric insole Manufacturers

After laying and connecting the composite geomembrane, immediately (within 48 hours) backfill the sand gravel or earth material protective layer.

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.

With the growth of the service life of expressways, problems such as network cracks, grooves, and cracks have appeared. It not only affects the stability and comfort of the car, but also causes surface water to penetrate into the road base and weaken the bearing capacity of the road base.

Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying the impermeable membrane, please make sure that there is no gap in the corner. If there are gaps, they should be filled in time during construction, and the laying order should be determined according to the specific conditions of the moisture content of the laying site. If there are pores, the air should be vented at the air bubble, and the anti-permeable membrane at the vent should be cleaned for subsidies.

According to the experience and lessons of the relevant engineering projects, in the real anti-seepage process, the peripheral access of the composite geomembrane usually becomes the most vulnerable or the weakest point where problems occur.

The placement process of HDPE geomembrane includes material cutting, test welding, welding equipment debugging, anchoring, inspection and acceptance, etc.
