What is the difference between a geogrid and a geocell?

Geocells and geogrids are new geomaterials used in roadbed, slope protection and other projects, geocells and geogrids have the characteristics of high compressive strength, strong bearing capacity, small deformation, corrosion resistance, high friction resistance, long service life, time-saving engineering and construction, short cycle, low cost and so on.

The essential difference between geocell and geogrid
Geocell is a three-dimensional mesh structure unit structure made of reinforced HDPE sheet material, welded by high-strength welding. Geogrid is the use of polypropylene, polyethylene and other polymer materials by thermoplastic or moulding, made with a certain aspect ratio of two-dimensional grid pattern or three-dimensional grid screen. Geocells and geogrids are all made of lightweight polymer materials with high strength, strong bearing capacity, small deformation, small creep, corrosion resistance, large friction coefficient, long life, convenient construction, rapid construction, etc. They are used in a series of soft foundation treatment, foundation reinforcement, retaining wall, ground crack-resistant fibre engineering projects such as pavement infrastructure construction.

Comprehensive difference between geocell and geogrid
1, geocell for three-dimensional reinforcement, geogrid for plane reinforcement; geocell for three-dimensional grid cell structure, geogrid for a certain height of the two-dimensional grid or three-dimensional grid screen structure.

2, geocell is three-dimensional mesh structure, geogrid is two-dimensional grid or three-dimensional grid with a certain aspect ratio.

3, geocell lateral restraint, bending stiffness is better than geogrid; geocell bearing capacity, distribution of load effect is better than geogrid;

4, omit economic development costs, geocells and geogrids are high quality and low price, and geocells are higher than geogrids.

The difference between geogrid and geocell is reflected in the use of
1, the use of geogrid is road plane reinforcement, geocell use is slope three-dimensional reinforcement, the two work on different principles.

2, geogrid by two-way force to produce tensile strength, known as tensile strength, and geogrid for three-dimensional shape, in the vertical direction can produce a great combination of force, this combination of force is to limit the soil body lateral and lateral expansion displacement, used to fix the slope of the vegetation root system, so that it is rooted in the stable soil layer, growth, so as to green the slope environment, maintain soil and water.

3, geogrid for square mesh structure, and geogrid honeycomb three-dimensional structure, mesh size varies greatly, geogrid mesh 2cm, 4cm, 6cm, 12cm, geocell mesh size is very large, can be customised according to the construction requirements, common on dozens of kinds.

Geocell features
1, geocells can be large or small, can be put away during transport, construction can be applied prestressing, tensioned into a mesh structure, filling soil, gravel, concrete and other loose raw materials, to form a strong lateral restriction and greater flexural rigidity.

2、Geocell material is light, wear-resistant, stable organic chemical properties, light-resistant, oxygen brittle, corrosion-resistant, and can adapt to different soil layers, deserts and other soil conditions.

3、Geocell high side limit and ground anti-skid, prevent deformation, improve the bearing capacity of the roadbed project and disperse the effect of load.

4, change the geocell length and width ratio, welding distance and other geometric specifications, can meet the needs of different projects.

5、Geocells can be large or small, with small transport size; easy to connect and faster construction.

Geogrid characteristics
1、Geogrid has high strength, small creep, adapts to all kinds of environmental soil, and can meet the use of high grade highway high retaining wall.

2, geogrid can improve the reinforced bearing surface of the bite, enhance the bearing capacity of the foundation, inhibit the lateral displacement of the soil body, enhance the stability of the foundation.

3、Geogrid has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large coefficient of friction, pore uniformity, convenient construction and long service life.

4, geogrid is more suitable for deep sea operation, reinforcement of embankment, solved the other material gabion low strength, poor corrosion resistance, service life shortened by the long-term scouring of seawater and technical problems.

5、Geogrid can avoid construction damage caused by mechanical crushing and damage in the construction process.
