Product Description:


Geonet is high density polyethylene (HDPE) and anti UV agent processing, has anti-aging, corrosion resistance and other characteristics. The use of effective load distribution of highway, railway subgrade, improve the bearing capacity and stability of foundation, prolong life. Laying in the road slope, can prevent landslide, soil conservation, beautify the environment. Reservoir, river dam protection  can effectively prevent collapse; in the coastal engineering for its good flexibility, good penetrability to cushion the impact energy waves break.




1). Excellent drainage function, can bear long time high press road


2). High tensile and shear strength


3). Reduce the rate that geotextile embedding into the core of geonet, can protect long time stable water conductivity


4). Can bear more than 2000KPa compression load


5). Its anti-compression capacity is much larger than common geonet for drainage.





Landfill drainage; roadbed and road drainage; railway drainage, tunnel drainage, underground structure drainge, the retaining back wall drainage, gardens and sports grounds drainage.



1, strengthen pavement stability, prevent crack;

2, can bear load;

3, to avoid cracks caused by frost heave;

4, can reduce the dosage of pavement materials, speed up construction.

Q:Is black HDPE geomembrane eco-friendly?
Raw material of HDPE geomembrane is HDPE particles, adding carbon black to become black. It is buried underground to prevent hazardous liquid leakage. So HDPE geomembrane can be considered as environmentally friendly.
Q:How to buy mulch applicator?
How to choose mulch applicator: classification Ø coated mulch applicator includes three parts: sizing, drying and hot pressing, having a broad scope of application and stable, reliable machinability. Ø pre-coated mulch applicator does not have sizing and drying parts, small and easy to opearte, which is not only suitable for film mulching process for large quantities of printed matter, but also for film mulching process for small quantity and bulk printed matter of automatic desk office system. terminology Ø single roll: There are only two couter pressing rubber rolls when mulching film. Ø double rolls: There are four couter pressing rubber rolls when mulching film. Ø single side: mulch film only on one surface of the product, usually the upper surface. Ø double sides: muIch film on double sides of the product, usually the upper and lower surfaces. Ø material receiving: For the label, protective film or 3M film and other products with release paper, tear off and recycle the release paper before mulching film. Ø single transport: single side conveyor belt for rubber roll. Ø double conveying: double sides conveyor belt for rubber roll. Ø hot mulching film : Mounting special hot film in device heated to certain temperature (about 100-180 ℃) is called heat mount, divided into single sided hot mounting and double-sided hot mounting. With good light permeability, waterproofness, heat resistance and strong hardness, it is suitable for post production advertisings against the backdrop of light or in other occasions. Ø cold mounting film mulching: Mounting the protection membrane on the surface of picture through cold pressing method is called cold mounting. divided into single and double side mounting. It is widely used in post production of advertising lamp box, engineering diagram and wedding photo, and in sheet metal industry (aluminum , iron, plastic, wood, steel, glass plate, etc.)
Q:what's the distinguish between geomembrane and waterproof board?
Basements and tunnels; tailing dam, rockfill dam; waste storage; construction cofferdam; m2-800g & # 47; channels: Membrane thickness from 0: anti-seepage, isolation purposes, waste water reservoir dam and reservoir area, tunnel anti-seepage lining: Geotechnical dam, highway: 4-6-meter: Two cloth one membrane (both sides of the impermeable membrane are added with protective geotextile) one cloth one membrane (one side of impermeable membrane is added with protective geotextile) width, railroad embankment .8mm protective layer of geotextile from 100g & # 47.2mm - 0; roadbed and other foundation saline control, masonry dam and concrete dam development pressure; leakproof roofing product features; roads, Khouang); dike, reservoir tank (pit; underground; expansive soil and collapsible loess waterproof layer, dam levels impervious blanket, ground vertical impermeable layer
Q:How to use electrothermal film?
Clip must be used on one of the ends of the wire and then connect the wire, wrap with daub and black rubber in case of electric leakage, and on another end of the wire should be wrapped with professional daub and black rubber in case of electric leakage. It is about 200 watts per square meter.
Q:What is the role of the geomembrane?
The full name of geomembrane is "high density polyethylene", with excellent property of environmental stress cracking resistance, low temperature resistance, aging resistance, corrosion resistance, larger using temperature range(-60--+60) and longer service life for 50 years. It is widely used in anti-seepage projects such as landfill of life waste,solid landfill, sewage treatment plant, artificial lake, and tailings treatment.
Q:The geotechnical membrane technology of urban construction?
The welding construction must be synchronized with the geomembrane one after another. The slope geomembrane is laied from up to down in a whole and cannot be splited joint. The upper left shoulder slope and anchorage capacity, and the lower end to the bottom of the pit left head slope root distance of not less than 1.8m, membrane end alignment with hot wedge welder connection. The slope shoulder is welded with extrusion welding. The seam should try to avoid the corner groove in the corner, and try to minimize the irregular shape. If it can not avoid the corner ditch, you must use a squeeze welding machine welding seam. In the crossed welded seams, it must be used to weld the welding machine welding. The length of welding shall not less than 20cm. Before welding, the welding seam should be trimmed to the exposed welding seam, and then the welding machine can be used to fill up the welding machine with the hand wheel.
Q:What are the specifications of plastic film
The measurement of thickness and refractive index of dielectric thin film by ellipsometry is widely used in modern science and technology. Therefore, the measurement of thin film technology has been greatly developed, ellipsometry is one of the most accurate methods of measuring thin film developed since 70s with the wide application of electronic computers. Ellipsometry measurement has the following characteristics: Can measure a very thin film (1nm), and the accuracy is very high, 1-2 orders of magnitude higher than the interference method. Is a non destructive measurement, without special preparation of samples, nor damage to the sample, compared to other precision methods: Such as weighing method, quantitative chemical analysis method is simple and convenient. The thickness, refractive index and absorption coefficient of the film can be measured simultaneously. So it can be used as an analytical tool. Is very sensitive to some surface structure, surface process and surface reaction. Is a method of studying surface physics.
Q:Can plastic wrap be steamed?
It is best not to use preservative film in steaming. The preservative film is composed of polyvinyl chloride, which is non-toxic at room temperature. But it mustn't be heated, for after heating, it will produce toxins which are harmful to human body.
Q:what's the items needed to be noticed in the pavement of composite geo-membrane?
Avoid stones, bricks and hard objects, geomembrane construction can be fixed submerged. Avoid uneven subsidence. 3, to avoid sharp objects hurt, can also be used with anchor nail 1, the roots should be cleared, laying the ground for a smooth, while laying flat at best or bottom of the embankment to accommodate the deformation of the matrix: 6, according to different circumstances, pull hard, without stones, pulling should be avoid when paving composite geo-membrane, the joints of composite geo-membrane should avoid side slope, and leave certain stretching and cracks.
Q:How to use 3M light box film?
There are many kinds of light box film, colored semi transparent film, uniform light film, light blocking film, double color film, etc. Color semi transparent film is the most commonly used. There are many colors for you to choose. Customize colors according to customers' demand. Make back lighting display board by cooperating with soft lamp-box fabric. The construction method of film sticking is divided into: Dry paste method and wet paste method. It depends on different products.
