The Difference Between Fiber Glass Geogrid and Steel-Plastic Geogrid

The difference between glass fiber geogrid and steel plastic geogrid

Glass fiber geogrid and steel plastic geogrid are different in material, use and performance, the following are their main differences:

Material：

Glass fiber geogrid: mainly made of glass fiber, made of mesh structure material through a special weaving process, and made of coating treatment process.

Steel-plastic geogrid: It is made of steel bar as the skeleton, combined with plastic material.

Use：

Glass fiber geogrid: Because of its high temperature resistance, it is usually used for asphalt pavement to prevent road breakage. It can be closely combined with asphalt mixture to improve the bearing capacity and crack resistance of pavement.

Steel-plastic geogrid: mainly used for subgrade reinforcement, with high strength and low creep characteristics, suitable for a variety of environmental soils, especially for large retaining walls and other occasions requiring high bearing capacity.

Property：

Glass fiber geogrid: has the characteristics of high strength, high modulus, good wear resistance and cold resistance, and no long-term creep, good thermal stability. Its surface is coated with special modified asphalt, which improves the grillability and shear ability.

Steel-plastic geogrid: also has high strength and large bearing capacity, and has the characteristics of large friction coefficient and uniform hole, convenient construction and long service life. It is particularly suitable for deep sea operations and bank strengthening.

Construction method：

Glass fiber geogrid: When laying, ensure that the laying surface is smooth, use U-shaped nails to fix the end, and then slowly pull forward, and manually straighten every 10 meters long. During the laying process, pay attention to the overlap length and fixing method.

Steel-plastic geogrid: when laying, the main force direction should be perpendicular to the axis direction of the embankment, the laying should be smooth, without wrinkling, and as tight as possible. Layers should be staggered between layers to ensure the stability of the overall structure and uniform force.

In summary, although both glass fiber geogrid and steel plastic geogrid are reinforced materials used in civil engineering, there are obvious differences in material, specific use and construction methods, and the selection needs to be determined according to the specific engineering needs and environmental conditions.
