Plastic geogrids used in civil engineering are typically made from high-density polyethylene (HDPE) or polypropylene (PP) for strength and durability. Plastic Geogrid is used with gabions for soil retaining and river bank protection gabion wall construction works.

Geotextile fabrics and grids are all synthetic non-woven materials for gabions works: Geo textiles are used as drainage and filter cloth, geogrids are mainly used for reinforcing, stabilizing, and separating soil in construction projects.
1,Plastic geogrid: High-density polyethylene (HDPE), polypropylene (PP), or polyester (PET).
2,Fiberglass Geogrid
Different Geogrid Materials we supply are made for different uses:
Three Major Geogrid Structures
Uniaxial, Biaxial, Triaxial.
Biaxial Geogrid: Biaxial geogrids have a square or rectangular grid pattern with ribs that run in both directions. Biaxial geogrids can be used in a wider range of applications in reinforcing soil foundations, retaining walls, and embankments. Biaxial plastic geogrids offer a good balance between cost, performance, and ease of installation for gabion works.
Triaxial Geogrid: Triaxial geogrids have a 3-dimensional structure with ribs running in all three directions (longitudinal, transverse, and vertical). Ideal for applications in soft soil conditions or steep slope stabilization.
Fiberglass Geogrid
Fiberglass Geogrid with asphalt coated 40kn x 40kn
Geogrid composite (50kN Bi-axial Fibreglass Geogrid Knitted with 140 Gsm PP non-woven Geotextiles)
Geogrid is used to reinforce:
Dyke;
Roadbed;
Side slope;
Tunnel wall;
other reinforcing construction works.
Benefits:
1. Increase the bearing capacity of the roadbed and foundation and prolong their service life.
2. Prevent road surface and foundation from sinking or flawing, keep clean and beautiful ground surface.
3. Convenient construction saves time and labor, reduce mounting time and decrease maintenance expense.
4. Prevent culverts from flawing.
5. Enhance earth slope and prevent water loss and soil erosion.
6. Decrease underlayer thickness and save manufacturing cost.
7. Enhance the stability of side slope turf net patch to improve greening.
8. Replace wire netting used in mine as intermediate ceiling netting.

Notes:
All dimensions are in mm
Gabion wall made up of gabion mattress and biaxial geogrid BX PP or equivalent.
Gabions are made with 250mm to 50mm norminal size hard stones.
Gabion units are tied with adjacent units.
Gabion wall to be constructed after making trench of minimum 1.0m deep below river bed.
Bank of river edge is cut to slope not steeper than as shown in drawing. Bottom of slope shall be compacted well. Slope may be made with available local soil. Constructed bank slope should have minimum 95% standard proctor density.

The tensile strength of pp geogrid is higher than that of the diamond mesh used in mining.
Features:
High-strength material and the mesh joint is firm
Low extension: Low unit extension, average stress, and avoid the appearance of the tuck net effectively.
Light: Weigh about 1kg/m2, with less labor intensity, improved working efficiency, and simple installation.
Safety: Static resistant, inflaming retarding, avoid the appearance of the electric sparkle effectively.
Erosion resistance: PP and PE surface ensures long service life and no invalidation caused by the erosion.
