- Q:What is a polyester filament geotextile? Polyester filament geotextile
- In addition to a good mechanical energy, but also has a good vertical and horizontal drainage and good extension of energy and high resistance to biological, acid and alkali, anti-aging and other chemical stability. At the same time, also has a wide range of pore size, tortuous pore distribution, excellent permeability and filtration can be polyester filament geotextile purposes: water conservancy project dam and slope protection filter, channel isolation, seepage; Airport runway foundation isolation, filter, drainage, soil slope, retaining wall and road reinforcement, drainage; port engineering soft foundation treatment, beach embankment, harbor wharf and breakwater reinforcement, drainage; polyester filament geotextile Has been widely used in the field of infrastructure construction, and gradually applied to a wider range of areas.

- Q:Do you need to use geotextile for construction site? Mainly used where?
- What do you want to specify? In what position. Are generally used in waterproof engineering.
- Q:edge of the road map layer asphalt laying anti-seepage geotextile how to set the amount?
- You can go to the civil online forum to ask questions, there are a little more professional.
- Q:Geotextile (250g / square meter) offer
- 250 grams of short fiber geotextile Price: 2.30 yuan / square meter 250 grams of filament geotextile Price: 3.70 yuan / square meter 250 grams of impervious geotextile Price: 2.80 yuan / square meter.
- Q:What is the consequence of the geotextile of the ground floor
- What are the consequences of what can not be finalized, the first roof of the waterproof layer and waterproof protective layer is very important, this is the first barrier, imagine, now many of the green plants are large trees, grow 10 years or even 20 years After the roots will be very developed, think about how the pine trees on the tenacious know their strength, coupled with long-term erosion by the water, the concrete layer will gradually lose its ideal performance, barrier layer and drainage board will certainly be better To protect the role and drainage. Well, long-term perspective, then we must do a solid job every layer, only focus on economic interests and short-term effects, then, within a few years will not be any problem, this is the status of China's construction industry. But the debt owed sooner or later.
- Q:How to apply geotextile soil
- General geotextile cloth in the drainage layer above the geotextile covered with soil
- Q:Alteration of highway seepage control geotextile is generally placed in what position
- Apply to the grassroots level of water defense, the use of embedded, covered with thickness should not be less than 30CM, soil to be solid, to avoid uneven subsidence, cracks. Lap width should be greater than 15CM.
- Q:Garage roof to do the garden, waterproof layer above the protective layer of gravel 10 cm above the ground and then geotextile
- So that you can get a 2-3 cm wide trail, from high to low, once again after the rain, so that the water may be smaller, if there is any doubt you can find a professional company asked, Tsinghua waterproof building materials, professional Waterproof construction technology.
- Q:300g / m2 geotextile package is what it means
- 300g / m2 Geotextile: refers to the weight of 300g per square meter (model) 300g / m2 geotextile package: refers to the outsourcing; with 300g of geotextile to wrap something; for example: With 300g / m2 geotextile wrapped gravel. The
- Q:What are the geotextiles for concrete health
- Concrete health with the geotextile, I probably understand what you mean is planted in the above plant flowers and the like, it can be used Daxiang non-woven geotextile can, and hope to help you!
