Tri-dimension Composite Geonet Introduction
Tri-dimension composite geonet is a new type drainage material. It has three layers: three-dimensional geonet and nonwoven geotextile on both sides. The material of geonet is HDPE, and the material of geotextile can be needle punched PET/PP nonwoven geotextile, and thermal bonded continuous filament nonwoven geotextile.
Tri-dimension Composite Geonet Specification
Thickness of geonet: 5mm to 8mm
Weight of geotextile: 200g/m2
Width: 2m-4m
Length: as request

Tri-dimension Composite Geonet Property
Tri-dimension composite geonet has the property of geotextile (filtration function) and geonet (drainage and protection function), it can provide a function system: filtration-drainage-protection. The core of net with its unique tri-dimension structure can bear high compression load in construction and remain certain thickness, provide good water conductivity.
Tri-dimension Composite Geonet Application
Landfill drainage, roadbed and road drainage, railway drainage, tunnel drainage, underground structure drainage, the retaining back wall drainage, gardens and sports grounds drainage.



- Q:Civil engineering materials learned what is the use, how to apply to the community, work on!
- Civil engineering materials, the most important point of knowledge is certainly concrete, after the work of civil engineering is basically inseparable from the open. Material This course is a basic understanding, to understand the knowledge, followed by the use of knowledge, such as the future to do a project, according to the engineering environment to use different characteristics of the concrete. If you say that is life, after all, this course called civil engineering materials, mainly to introduce you are used in civil engineering materials.
- Q:What is the civil engineering material
- Some material shopping guide
- Q:Why civil engineering materials are important
- Civil engineering materials are important
- Q:Why beginners or senior civil engineering and technical personnel are required to continue to learn civil engineering materials
- Urban development is much faster than mass maternity leave
- Q:Is the glass made of wood?
- Glass is calcium carbonate, sodium carbonate, high temperature fired silica!
- Q:Civil Engineering Materials.
- Civil Engineering Materials. e Material saturated with water, and then dry the surface, is the hole filled with water or closed hole filled with water? What is the condition of putting the material in a jar filled with water? Not to say that the closed hole is not water?
- Q:What are the civil works?
- Main works: engineering mechanics, fluid mechanics, rock mechanics, foundation and foundation, engineering geology, engineering drawing, computer application, building materials, concrete structure, steel structure, engineering structure, water supply and drainage engineering, construction technology and management Structure, engineering survey, housing architecture and so on. The main practical teaching links: including engineering drawing, learning practice, measurement practice, engineering practice, professional practice or production practice, structural curriculum design, graduation design or graduation thesis, the general arrangement of about 40 weeks. 0 0 major professional experiments: material mechanics experiments, building materials experiments, structural tests, soil tests.
- Q:Material science and civil engineering which is better?
- According to the different options of the school
- Q:Briefly describe the technical requirements of civil engineering for the use of its building materials and explain its reasons
- For example, as the structure of reinforced concrete requires mechanical properties of the requirements: such as strength, elastic modulus, shrinkage and so on; physical properties, apparent density, impermeability and durability
- Q:The Importance of Civil Engineering Materials in Engineering Construction
- Different types of materials, mechanical coefficient, the construction method will be different, the impact of the construction process, the impact of the demand for materials, the impact on the cost of the project impact, the impact on the quality of the project.
