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.

In the design of roof waterproof structure, due to the consideration of structural deformation, temperature deformation, shrinkage deformation, vibration and other influencing factors, it is necessary to take the key to deformable parts such as deformation joints, partition joints, roof ridges, cornices, gutters, water downs, entrances and exits. An additional reinforcement layer is provided on the site.

Geomembrane is a flexible geosynthetic impermeable material, and the stability of its underlying support layer is one of the keys to the safety of geomembrane. If the underlying support layer has obvious uneven deformation and local erosion, the geomembrane will be partially torn, forming a leakage channel, threatening the safety of the project.

In which fields can the anti-seepage geomembrane be used, I will give you a detailed analysis today.

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.

The composite geomembrane uses the following new technologies to improve the anti-seepage effect.
