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: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:Why do the basics of the cushion waterproofing
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:What is the waterproof layer and the waterproof cushion in the tile roof?
Waterproof: In order to prevent rainwater from entering the roof, groundwater infiltrates the wall, the basement and the underground structures, and the indoor water penetrates the floor and the wall.
Q:Foam concrete for the roof cushion generally do much bulk ah
in recent years, the density of 160kg / m3 ultra-light foam concrete is also used in construction projects.
Q:What is the relationship between the cushion and the ring beam?
Ring beam is reinforced concrete. Is to increase the overall wall and overall stiffness, improve the side resistance performance, according to the earthquake or masonry specifications set. There may be in the ground wall, there may be in the underground wall.
Q:The top floor made waterproof playing cushion layer of how to do
Roof waterproofing can not use a single waterproof material, must be rigid and flexible combination of construction, flexible waterproof stretch is good, a little bit of settlement or deformation will not damage the waterproof layer. Rigid waterproof (ie mortar waterproofing agent) waterproof at the same time, can play a protective role, waterproof layer is not easy to be destroyed.
Q:Is it possible to make a waterproof layer
1, to do after the dry do, or prone to the phenomenon of wall skin off.
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:What is the difference between leveling and cushion?
and only in the construction of the building at the bottom of the building, it is possible to use the relevant level of the cube, After the use of the underlying layer of the building, it is not exempt from the possibility of using leveling layer
Q:Is the raft cushion waterproofing full of the cushion?
The request is full. Raft foundation do not do waterproof mainly depends on the design of the groundwater level considerations, calculated if the floor itself to meet the requirements, you can not do, and not rigid to do.
