Structure of Polyester Nonwoven Geotextile Description:

Polyester Short fiber needle nonwoven geotextile  is a new type of construction materials which is defined to use in construction projects. The main roles of geotextile include filter, water treatment materials and georeinforce. Materials. Needled staple fiber geotextiles show excellent filtration effciency, isolation, reinforced protective effect, high tensile strength, good permeability, high temperature resisting, anti-freezing, anti-aging, corrosion resistance.

Main Features of Polyester Nonwoven Geotextile

1.Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different

granule pathway from the groundsill or other buildings. 
2.Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability. 
3.Protection 
It prevents the bank from being washed out, protects the bank and the

bottom, prevents the water and soil from being washed away

Q:The repair method and quality inspection of composite geo-membrane construction defects.
It's really hard, first melt the geotextile with iron plate, pay attention to the melting degree, half exposed of PE film is ok. then use a layer of one fabric and one membrane film to connect it, and it's suitable for the film over 0.4, the thin film can only be pasted with PEglue. you can pull up the repair part and put water into it for inspection. you must leave some cloth while construction, otherwise, high pressure will makes the repair parts crack.
Q:What are the manufacturing techniques of electrothermal film?
Technology: 1. electrothermal film wires should use different color: phase line----- the same color as the household power supply line. control line----black insulated wire; N line ---- blue insulated wire; PE line - green and yellow insulated wire. 2. use wires to connect the wires between electrothermal film groups. The contacts should be pressed with special press plier in special cylindrical tube and pull the wires.
Q:How many models of composite geo-membrane are there?
The followings are composite geo-membrane specifications and models: one cloth and one membrane(cloth: 100-1000g / m2 Thickness of membrane: 0.1-1.5mm) two cloth and one membrane (cloth: 80-600g / m2 Thickness of membrane: 0.2-1.5mm) one cloth and two membrane (cloth: 100-1000g / m2 Thickness of membrane: 0.1-1.5mm) multi cloth and multi membrane(cloth: 100-1000g / m2 Thickness of membrane: 0.1-0.8mm)
Q:Does seepage-proof membrane belong to geomembrane?
Geomembranes are widely used for their excellent seepage-proof performance measured by order of magnitude of 1*10*-13. The basic function of which is cultivation. The seepage-proof performance is good, but you'd better choose environmental ones with GBT17642-1998, GBT17643-2008 as well as other specifications and standards as reference.
Q:Composite geomembrane (350g / 1.0mmHDPE / 350g) What does it mean?
the specification of composite geo-membrane Geomembrane cloth membrane, also known as two cloths film one film, 0.01-mm high-density geomembrane composite geomembrane on (350g / 1.0mmHDPE & # 47, the thickness of the intermediate impermeable film quality is 1: Both sides of the geotextile (geotextile) mass per unit area is 350 g
Q:what's the principle of composite geo-membrane protecting impervious barrier?
composite geo-membrane takes plastic film as seepage-proof base material, it's the soil engineering seepage-proof base material composed by non-woven fabrics, and it's seepage-proof performance mainly depends on the seepage-proof performance of plastic film. it's dominant mechanism is isolating the earth dam leakage passage with the imperviousness of plastic film, it's good strength of extension and elongation can endure hydraulic pressure and adapt deformation of dam; non-woven fabrics is also a kind of macromolecule staple fibre chemical material, it's made by needle punching or hot sticking, and has high strength of extension and extensibility, after combined with plastic film, it not only has increased the strength of extension and anti-puncture ability of plastic film, the rough surface of non-woven fabrics has increased the friction coefficient of contact surface, which is benefit to the stability of composite geo-membrane and packaging layer. meanwhile, they have good corrosion resistance to bacteria and chemical function, and can be resistant to the errosion of acid, alkali, salt.
Q:What are the differences of seepage-proof membranes, geomembranes and waterproof membranes? Can they be used together?
Seepage-proof membranes are mainly used in the waterproof control of civil engineering, are also widely used in municipal public sectors and highway engineerings, especially are commonly used in the slope protection; geomembranes are seepage-proof membranes with geotextiles as main materials.
Q:What is the difference between geomembrane and impermeable membrane?
Impermeable membrane is impermeable geomembrane, including geomembrane, composite geomembrane, two cloth a film, a cloth a film. Geomembrane is HDPE geomembrane, geomembrane is a kind of polymer as the basic raw material waterproof barrier material. Mainly divided into: polyethylene (PE) geomembrane, PVC (PVC) geomembrane, chlorinated polyethylene (CPE) geomembrane and a variety of composite geomembrane and so on. Function: seepage, isolation purposes: geotechnical dam, rockfill dam, masonry dam and pressure concrete dam; dike, dam front level anti-seepage cover, vertical foundation impervious layer; tailings dam, sewage dam dam and reservoir Construction of cofferdam; channel, reservoir (pit, Khouang); waste yard; subway, basement and tunnel, tunnel seepage lining; highway, highway, railway roadbed; roadbed and other salt control; Collapsible loess waterproof layer; roof leakage products: two cloth a film (impermeable membrane on both sides with protective geotextile) a cloth a film (impermeable membrane side with protective geotextile) Width: 4-6 meters
Q:Polyethylene geomembrane perennial soaked in water will not release harmful gases
soil cylinder and hydraulic oil. when operational pressure reaches dozens of MPa, hydraulic oil will be soaked in water. Since the water density is smaller than that of oil, so it is easy to mix them.
Q:slope geomembrane sliding treatment program
strengthen the anchoring ditch,
