Product Description:


Geocomposite Drainage



Brief Description:


Geocomposite drainage is a drainage system consisting of three-dimensioanal high-density polyethylene


geonet, with high permeability, compressive strength and tensile strength, combined on one or both sides with


a nonwoven polypropylene geotextile. 




1. Three functions in one unit: filtration, drainage and protection.


2. The installation is simple and rapid comparing to traditional sand grains and gravel layer.


3. Cost-effective substitute for traditional drainage system provide savings on materials, transportation and in-




4. Chemically resistant construcion provide long life in harsh environments.

Specifications and technical parameters:

  Drainage network core 



Unit weight 












Hydraulic conductivity 











Tensile strength 

(core netwaork) 







Heavier grades of geotextiles can be bonded to geonet on request 


 In the railway, highway and other transportation infrastructure, drainage system safety and the service life

 of the project and its have inseparable relationship, in which the geotextile material is an important part 

of drainage system, the drainage effect of 3D composite drainage net is particularly notable. mainly 

used for tunnels, municipal engineering, reservoir, revetment in drainage engineering.

Q:Civil engineering expertise which to master the technology (specific point of speaking)
Civil engineering is the construction of various types of engineering facilities of science and technology collectively. It refers to the technical activities of the materials, equipment and facilities carried out by survey, design, construction, maintenance and repair; also refers to the object of construction, that is built on the ground or underground, land or water, directly or indirectly for human life Construction, military, scientific research services such as housing, roads, railways, transport pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage and protection works The material basis of the facility is land, building materials, construction equipment and construction machinery. With these material conditions, economic and convenient to build both to meet people's requirements and aesthetic requirements, but also safe to withstand the load of various engineering facilities, civil engineering disciplines is the starting point and destination
Q:architecture material
Slag Portland cement (referred to as slag cement), volcanic ash Portland cement (referred to as volcanic ash cement) and fly ash Portland cement (referred to as fly ash cement) are made of cement clinker. Mixed with the amount of gypsum made of fine. Wherein the variety and the content of the mixed material are different. The mixed material of the slag cement is granulated blast furnace slag, and the blending amount is 20% ~ 70% by weight; the mixed material of the volcanic ash cement is a mixed material of volcanic ash, the dosage is 20% ~ 50% by weight; Fly ash cement in the mixed material is fly ash, blending by weight percentage of 20% to 40%.
Q:Civil engineering graduation, after work which test is good?
Civil engineering professional research types and conditions First, after graduation a year after the automatic conversion to assistant engineers, as assistant engineers after four years of assessment engineers. If you are engaged in the construction of the building on the construction division to do a certain time after the test of a supervision engineer. If you engage in the settlement of the test on the cost division or economist. If you engage in the design of the architect or architect or rock division. A supervisor of the supervision of the engineers. Of course, can more work to more test on the test. The supervisor of the maximum number of years so the final test budget, construction workers, quality inspectors, security officers, materials
Q:Now undergraduate civil engineering, what courses, which textbooks?
Main courses: engineering mechanics, fluid mechanics, rock mechanics, foundation and foundation, engineering geology, engineering hydrology, engineering drawing, computer application, building materials, concrete structure, steel structure, engineering structure, water supply and drainage engineering, construction technology and management
Q:Why civil engineering to solve the problem is to give full play to the role of materials
Cost-effective, with its own things have their price Well High-end material performance is good, the same high price, if the project does need this high-end materials to meet the construction requirements, it can only use this, because the general material will cause engineering quality problems. However, if the general performance requirements, that is, ordinary materials can be resolved, then use ordinary materials like, without the need for high-end materials, which can save costs.
Q:What is civil engineering and architecture?
Two professional comparison in the design industry is most obvious, is two professional called architecture and structural professional. The former concept of the program, consider the function and layout, which consider the internal reinforcement and other structural problems, to achieve the former concept, both with water, warm, electricity professional to complete a project design.
Q:What are the raw materials for civil engineering?
Engineering need to do the re-test of raw materials: steel, brick, cement, sand, stone (if it is not a commodity concrete) waterproof coating, waterproof membrane
Q:Civil Engineering Science and Technology Examination
To pay more attention to their school, you can go to see the school graduate network, or the school Post it, where it should be more convenient to get what you want!
Q:Civil Engineering Materials
Autoclaved aerated concrete block is characterized by a large drying shrinkage, the kettle after a week that is masonry, is not completely dry caused by shrinkage cracking.
Q:Material science and civil engineering which is better?
According to the different options of the school
