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:Is foam concrete suitable for use as a cushion?
- The foamed concrete is a foaming system through a foaming machine that allows the foaming agent to be fully mechanically foamed and the foam is mixed evenly with the slurry.
- Q:How to build a fine stone concrete cushion?
- The cushion is primarily responsible for the load coming from the surface and passes the load evenly to the structural or base.
- Q:Can the cushion on the prefabricated board floor be dug?
- Surface layer without steel, do not bear the load, you can dig out
But sometimes the prefabricated floor above the surface layer with steel, to bear the load, this can not be removed!
To know how thick the cushion, in the local dig about
In general, to do leveling layer, can not be directly laid tiles
- Q:Roof waterproof mattress should play the number of centimeters appropriate
- 3. The first layer to do flexible waterproof, that is, roof-specific anti-aging waterproof coating.
- Q:What is the relationship between the cushion and the ring beam?
- There is no direct relationship between the cushion and the ring beam.
- Q:The top floor made waterproof playing cushion layer of how to do
- 4. The second layer to do mortar waterproof (mortar waterproof), waterproof at the same time can protect the bottom of the flexible waterproof.
- Q:Is it possible to make a waterproof layer
- 2, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
- Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete
- hird, the relevant parts
Different types of rigid waterproof layer separation spacing in addition to meet the calculation needs, but also in the following parts set sub-grid joints.
1. The deformation of the roof structure sensitive parts;
2. Roof and roof drainage direction changes;
3. The junction of the waterproofing layer and the protruding roof structure;
4. Under normal circumstances, each bay load-bearing walls should be set sub-grid seam.
5. Between the waterproof layer and the load-bearing or non-load-bearing parapet or gable should be set sub-grid joints, and in the node structure for proper treatment.
- Q:What is the difference between leveling and cushion?
- Commonly used materials are, cement mortar leveling layer, fine stone concrete leveling layer, asphalt mortar leveling layer and so on. Leveling layer and the difference between the cushion, which is a very easy to confuse the two engineering concepts.
- Q:Cushion, waterproof layer construction to do what information
- 3, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
