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:Self-built concrete house finished three years after the use of large-scale housing wall leakage how to do?
Third, from the indoor water leakage area for waterproof maintenance.
Q:Waterproof mortar expensive or dry mortar expensive
Waterproof mortar more expensive. Because waterproof mortar compared to dry mortar, to add another waterproofing agent, emulsifier and other substances. Waterproof mortar regardless of the cost or transport are more cost-effective.
Q:Roof for the insulation, Master roof, using two waterproof construction program
Fourth, the finished product protection 1, has been laid the membrane waterproof layer, should be taken to protect the facilities, is strictly prohibited in the waterproof layer on the construction operations and transportation, and should be timely to do the protective layer of the waterproof layer. 2, through the roof, wall waterproof layer at the pipeline, construction and after the completion of damage shall not damage. 3, deformation joints, water, etc., before the construction of waterproof layer, should be temporary closure, waterproof layer is completed, should be cleared to ensure that the tube, sewn smooth, to meet the use of function. 4, roof construction shall not pollute the walls, cornices and other finished products.
Q:Waterproof material water leakage construction should pay attention to what
2, wall treatment · Wall treatment to do about 300mm high waterproof coating, to prevent water infiltration wall back tide. · Bathroom between the wall and the ground (plane and elevation) brushing height should be greater than 100mm. · The height of the shower room in the bathroom is not less than 1800mm. · If there is a bathtub, the height of the wall adjacent to the bathtub should be 300mm higher than that of the bathtub. · Waterproof height of tub is not less than 800mm. · The height of the squat should be more than 900mm. For the transformation of the toilet wall and self-built light wall, the proposed height of the waterproof to do the top.
Q:Finished house bathroom waterproof household acceptance should be how to accept?
Bathroom waterproof acceptance: material acceptance: 1: materials need to meet the national standards, the need for a product certificate of competency. Construction acceptance: 1: grass-roots surface should be flat, no hollowing, from the sand, cracking and other defects. Base water content should meet the construction requirements of waterproof materials.
Q:What are the key points and contents of the quality control of waterproof material?
3, infiltration of crystalline cement-based waterproof coating: on-site fraud is to use ordinary cement mixed with seafood powder (or 801 glue) so that the cement after the solidification of the color, it will not crack. Genuine infiltration of crystalline cement-based waterproof coating will have a hydrophobic effect that is the effect of lotus leaf water droplets (of course, this hydrophobic effect can not be too much, otherwise it will affect the next process of bonding).
Q:How can the toilet waterproof works fail?
Can only do a new waterproof, and now have engaged in the base of the waterproof coating, the effect is very good. It is best to ask professionals to do their own difficult.
Q:Oriental rain rain waterproof how to
Strict selection and the pursuit of excellence in product performance of the East Rainbow waterproof coating long-term waterproof material in the market leading the main reason. In order to test product performance, the East Rainbow company to the product to the plateau, desert, alpine, high temperature and other areas for testing.
Q:There is no formaldehyde in the finished putty
Often people are talking aldehyde color change, because the formaldehyde is very polluted environment contains a lot of carcinogenic substances, so into the wall inside unknowingly become an environmental killer.
Q:Find the construction steps for waterproof coatings
2, waterproof layer construction sequence and methods (1) base surface treatment and acceptance of qualified, and now Yin, Yang angle and construction joints and other special parts brushing waterproof coating layer, strengthen the layer 1 mm, strengthen the layer after brushing, immediately paste fiberglass cloth or 30 ~ 40g / ㎡ polyester cloth reinforcement layer, is strictly prohibited to strengthen the surface layer and then paste the reinforcement layer material. (2) to strengthen the layer of hard work, began to brush a large waterproof layer, waterproof layer using multi-channel (3 to 5) brushing, brushing the upper and lower coating should be perpendicular to each other. When the surface of the coating is completely cured (not sticky hands) before the next curtain coating construction. (3) polyurethane coating waterproofing layer after the completion of the experience of acceptance, the timely application of the waterproof layer of the protective layer, the plane protective layer with 7 cm thick fine stone ㎝, in the pouring of fine stone before the need to cover the waterproof layer A layer of 350 # paper tire linoleum insulation layer. Facade waterproof layer (such as anti-beam facade) with a thick 6 mm polyethylene foam protection (expansion ratio of not more than 25 times).
