FAQ of geosynthetics :

 

What is geosynthetics ?

 

Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary.

 

What kinds of geosynthetics we have ?

Q:How does the waterproofing membrane work?
3, the ignition: first open the liquefied gas cylinder switch, and then hand gun slowly open the gun switch, to be heard when the gas hissing sound, ignite the flame, and then adjust the switch, the flame was blue. Ignite people should stand behind the nozzle side, so as not to be burned by fire;
Q:Roof leakage, what materials do the best waterproof
Treatment is: large cracks available plugging the king, a small crack can be used to fill the glass glue, repair with a wall waterproofing agent, after spraying a few words on it. As the external walls of cracks and cracks need high-altitude operations, the public must ask the professional construction team to deal with, to prevent accidents. Roof leakage what materials: available SBS modified asphalt - polyester film coil, polyester film SBS-3mm, laying the coil. Roof waterproofing membrane, in addition to SBS modified asphalt, there are three EPDM coil, neoprene. Can also use architectural ointment, cement, polyurethane coating. You can also use asbestos net also do waterproof. If the cement roof cracks, I suggest you use cf-2000 efficient composite waterproofing agent. In the concrete like scraping putty scraping 5mm thick again, you can play a waterproof repair function. Can also slot repair.
Q:Roof sunscreen waterproof layer leakage, brush milk white plastic can solve it?
Fourth, for some of the construction of the roof of the cover of Hong Kong leakage, as long as the removal of tiles on the grass, moss or dust after the replacement of tiles, leak-proof effect is the same. For flat roofs, the roof of the obvious cracks, with the tool will be cracked into a "V" or "U" shape, filling the caulking ointment, filled with cracks and above the use of waterproof wrap around the package. To strengthen the leak-proof effect, you can also shop a layer of waterproofing membrane.      Roof leakage how to deal with five, most of the use of clean up the roof, crack filling, crack sealing, mortar to find equal maintenance methods. Waterproof methods are: membrane waterproof, rigid waterproof, flexible waterproof, waterproof coating and other methods. You can also use the plugging the king is better, for the seepage, slightly dug the slot can be directly plugging the dry powder into the tank, compaction, wiping, sprinkler can be maintained. If the investigation is your home to leak water, the main problem should focus on the surface of the leakage interface and the upper part of the section, it is recommended to find professional leak-proof, it is estimated that it is to spend tens of dollars, if you want to repair it To buy a waterproof paint, (the specific name of a lot to go to that kind of store that they know) and then painted in the floor drain and toilet under the mouth of the water pipe and the upper section can be.
Q:Home improvement waterproofing problem
4, through the door stone paving need to do waterproof, you can directly use cf-2000 efficient composite waterproofing agent treatment, can play paste, waterproof two effects. Just on both sides of the door to do the character to strengthen the treatment on the line can be foolproof.
Q:Why should the use of high pressure perfusion waterproof plugging method
High pressure grouting construction features: 1, a high degree of finished product 2, simple operation; reduce the construction time 3, the construction from the weather; 4, non-toxic pollution;
Q:Waterproof material water leakage construction should pay attention to what
3, do the closed water test After the waterproof construction is completed, the water storage test. Will be blocked all the toilet outlet, the door at a pound of about 200mm high barrier, and then poured in the bathroom about 20mm ~ 30mm deep water, and 24 hours after the inspection of the walls and the ground around the leakage phenomenon , Waterproof test is to ensure the quality of the bathroom waterproofing the key, we must do. Such as after 24 hours without leakage as qualified. If you find a leak, you should immediately stop the water storage test, re-waterproof layer to improve the treatment, after passing the water test.
Q:Finished house bathroom waterproof household acceptance should be how to accept?
5: the use of construction stubs should be along the direction of the flow of water, lap width of not less than 100mm, the use of two or more fiberglass cloth up and down when the overlap should be staggered width of one-half.
Q:I would like to ask how to do in the warm water above,
Do nothing to use, because the biggest leak to the hidden danger is to warm the water, but your waterproof design does not include the warm water, you say your waterproof layer construction, in the end how much significance. It is recommended to make the waterproof floor to warm the following, as to what kind of good is not good to say that good things, that kind of good is good.
Q:What is the difference between finished mortar and cement mortar?
Finished mortar white lime compounds, and cement mortar dark gray black.
Q:A complete set of basement waterproof construction program
Second, the basement of the external walls of water leakage construction preparation 2.1 Technical preparation 2.1.1 Selection of construction methods Waterproof engineering is related to the use of the project an important indicator, it is the construction process of a key project, difficult engineering. The choice of construction methods and programs has a direct impact on the quality of construction. The underground wall of the project SBS waterproofing membrane with hot melt method full construction. 2.1.2 before the start of the project, the first organization of engineering and technical personnel to enter the construction site, to understand the situation, to further understand the characteristics of the project to solve the contradiction between the construction technology and the implementation process. 2.1.3 technology before the end of the construction of waterproofing works by the professional foreman in accordance with the construction drawings and the existing national norms require the actual situation of the project to the construction team in writing to the end. The contents include construction site, construction sequence, construction technology, construction level, node fortification method, enhancement site and practice, project quality standard, guarantee the quality of technical measures. And after the field technical person in charge of the strict implementation of the audit.
