3. HDPE Geomembrane Applications  

1) Environmental protection, sanitation (such as solid waste landfills, sewage treatment plants, power plants Chi-conditioning, industrial, hospital solid waste, etc.) .

2) Water (such as rivers, lakes and reservoirs of the anti-dam, plugging, reinforcement of the canal seepage, the vertical wall of the heart, slope protection, etc.).

3) Municipal Engineering (subway, on the ground floor of the building, planted roof, the roof garden of anti-seepage, sewage pipes lining, etc.).

4) Landscape (man-made lake, river, reservoir, golf courses reservoirs of the substrate, slope protection, green lawn of the waterproof moisture, etc.).

5) Petrochemical (chemical plants, oil refineries, gas storage tanks of the anti-chemical reaction tanks, sedimentation tanks of the lining, etc.).

6) Mining (washing and pool heap leaching, the ash-field, dissolved, precipitation, the yard, the tailings seepage substrates, etc.) .

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:Roof waterproof mattress should play the number of centimeters appropriate
4. The second layer to do mortar waterproof (mortar waterproof), waterproof at the same time can protect the bottom of the flexible waterproof.
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:Is foam concrete suitable for use as a cushion?
Inappropriate. Bubble concrete is a new type of energy-saving and environmentally friendly building materials, which are widely used in wall materials, but there are still some defects, such as low strength, cracking, water absorption, as the cushion of its strength is not enough standard.
Q:Maintenance time of the cushion on the roof of the building
According to the "concrete structure construction quality acceptance criteria" provides: Concrete should be poured within 12h after the completion of the concrete to be covered, and moisturizing conservation;
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?
Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be removed, but be careful not to damage the prefabricated plate.
Q:Large area ground concrete cushion seam Why is the separation of joints generally concrete
Large area of ​​concrete after concrete construction, the concrete volume will be slightly inflated, the ground for a long time deposition, will be sinking, all large area of ​​concrete construction, the general set of separation joints.
Q:Do you need a cushion on the ground floor?
Chalet recommended to do sloping roof, the lowest point suggested 2.4. Talk about the ground, the roof, the wall area divided by the length of your board length and width of the area can be calculated on the amount of it!
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.
