nonwoven fabric interlining Manufacturers

The anti-seepage structure of the composite geomembrane consists of a protective layer, an upper buffer layer, an anti-seepage layer, a lower buffer layer and a support layer in sequence.

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.

When overlapping with the adjacent composite geomembrane, first expose the geotextile at the joints, sew the adjacent geotextile of the lower layer, adjust the welding edge of the two membrane layers, and weld the middle of the composite geomembrane with an overlap width of 150mm body.

The waterproof geotextile is a kind of geosynthetic waterproof material made of polyethylene as a moisture-proof base material and geotextile.

In some waterproofing layer engineering projects, carbon black is added to the material of HDPE anti-seepage geomembrane.

1. Excellent environmental adaptability: Most of the traditional geomembrane materials have a single performance, and there are not many methods that can be used.
