Geotextile used to prevent seepage water, geogrid used to reinforce.
Geotextile mainly used in water conservancy, for anti-anxiety, drainage, protection, isolation, can also be used to strengthen the road embankment. Geogrid is mainly used in roadbed to strengthen the roadbed, and retaining wall reinforcement.
The strength of geogrid geotextile much larger than geotextile on the road to prevent the role of reflective cracks, significantly stronger than the geogrid.

Geogrid and geotextile role is not the same, in simple terms, the role of geogrid is to stabilize the roadbed, extend the service life of the road. The main role of geotextile isolation, filtration, drainage, reinforcement, protection, the role of closure.

Geotextile is mainly used for anti-seepage, isolation, geogrid are generally used in reinforced reinforced, there are two essential differences in the use of the process sometimes used in the same project, such as high-speed, railway and other projects grid is made of polypropylene, polyvinyl chloride and other polymers by thermoplastic or molded two-dimensional grid or a certain height of the three-dimensional grid grid, when used as a civil engineering, it is called a geogrid. Engineering Applications: Roads, railways, abutments, approach Road, docks, dams, slag and other soft ground reinforcement, retaining wall and pavement cracking and other fields. Glass fiber mesh used in the external walls, paint the interior wall, the main material to prevent the junction of mortar plastering and other materials cracking, hollowing. Local node enhancement will be used. Geotextile has excellent filtration, drainage, isolation, reinforcement, seepage, protection, light weight, high tensile strength, good permeability, high temperature, antifreeze, anti-aging, corrosion-resistant. Common non-woven fabric, water layer used inside, polyethylene polypropylene waterproofing is also used.

Geotextiles, also known as geotextiles, it is made of synthetic fibers through the acupuncture or woven into the water-permeable geosynthetics. Finished fabric, the general width of 4-6 meters, a length of 50-100 meters. Geotextiles are divided into a woven geotextile and non-woven geotextiles. Geotextile has excellent filtration, drainage, isolation, reinforcement, seepage, protection, light weight, high tensile strength, good permeability, high temperature, antifreeze, anti-aging, corrosion-resistant. Geotextile with excellent filtration, isolation, reinforcement protection, high tensile strength, good permeability, high temperature, anti-freezing,
anti-aging, corrosion-resistant. Applied to the reinforcement of railway embankment, road pavement maintenance, sports hall, dam protection, hydraulic construction isolation, tunnel, coastal beach, reclamation, environmental protection and other projects.

Geotextiles are generally used in the treatment of weak foundations and pavement maintenance, the two sets of materials fixed 1-3-9, geotextiles and soft soil subgrade silt,geogrid is made of polypropylene, polyvinyl chloride and other polymers by thermoplastic or molded two-dimensional grid or a certain height of the three-dimensional grid grid, when used as a civil engineering, known as e s. Features: 1. High strength, small deformation; 2. Small creep; 3. Corrosion resistance, long life; 4. Construction is convenient, short cycle, low cost.

Thus, geogrid only for soft soil subgrade (or pavement grassroots). Calculation of the amount of construction by laying area, has taken into account lap area. Geogrid engineering applications: roads, railways, abutments, approach Road, docks, dams, slag and other soft ground reinforcement, retaining walls and pavement cracking and other fields. The grille is generally used in the combination of old and new roadbed and rigid-flexible road surface with good results.
