Geomembrane is a kind of waterproof material with basic raw material of high molecular polymer. It is mainly divided into LD PE geomembrane, , HDPE geomembrane, EVA geomembrance and all kinds of composite geomembrane.
Complete variety of specifications of width and thickness. Thickness: 0.08-2mm/Width: 2-16m .
Excellent environmental stress resistant cracking performance.
Excellent performance of chemical erosion resistance.
Big scope of application temperature and long service life .
Applied in landfill waste site, sewage and filth treatment site, tailings depot and underground construction project
- Q:The roof cushion is waterproof on the slope roof
- When the moisture generated by the ice dam into the external walls of the gap, the walls and insulation layer will become damp, which is the ideal environment for the breeding of mold.
- Q:Is the raft cushion waterproofing full of the cushion?
- As for the bottom of the bar thickness of the protective layer is generally 4cm, but if the basic floor of the concrete label is relatively high, the protective layer can be appropriately reduced.
- Q:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
- Cushion generally no steel mesh, even if there can be removed, it is used to inhibit the cushion cement mortar layer cracking.
- Q:Why calculate the amount of time to count a lot of cushion ah
- In the building construction refers to the base is located below the cushion sometimes also served as grassroots. With the cushion, in the above work is convenient, clean, especially the mold, bar reinforced, pouring concrete and other processes, will not be affected by the basic earth pollution. Set the place where the cushion is generally based, floor, roof (slope) and so on.
- Q:Basement floor mattress dry to what degree can do coil waterproof?
- Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. And then paste the membrane, and then in the coil to wear 20 thick 1: 3 cement mortar, and finally pouring reinforced concrete floor. The outer surface of the wall first wip 20mm thick 1: 3 cement mortar, cold base oil, and then paste the membrane, the membrane should be stitched paste, adjacent coil lap width of not less than 100mm. The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.
- Q:How to build a fine stone concrete cushion?
- Reduce ground cracking, plus steel mesh.
Reinforced mesh, should be placed in the middle of the concrete, because the protective layer of concrete thick Fang generally only 5CM thickness, so the middle is the best.
- Q:Foam concrete for the roof cushion generally do much bulk ah
- First help you correct it, foam concrete used in the roof should be the role of thermal insulation, not as a cushion.
- Q:Do you need a cushion for roof waterproofing?
- If the base layer of the waterproof layer is flat or in line with the requirements of the waterproof material process, you can not do leveling layer. For example, in the cast-in-place concrete roof with the pound with wiping light, may serve as the waterproof layer of the grassroots.
- Q:Why do the basics of the cushion waterproofing
- The general basis of the foundation, the bar base is not necessary to do, like a raft in the basement, it is necessary to prevent the water from dipping into the basement (so the basement design may have to do anti-floating calculations). Assuming (just suppose) the raft can easily turn over, then we do waterproof (like roof) directly on it, not waterproof on the cushion.
- Q:The cushion is usually in the housing which parts
- There was no other place in the house below
