The difference between geogrid and geogrid

The core difference between geogrid and geogrid chamber is structural and mechanical properties. The geogrid is mainly composed of a two-dimensional planar mesh structure, focusing on tensile resistance; the geogrid chamber is a three-dimensional honeycomb three-dimensional structure, with stronger lateral constraints and load dispersion capabilities.
1. Specific differences
‌Structure and Materials
‌Geo-chamber: A three-dimensional honeycomb structure is formed by welding high-strength HDPE sheets, which can be stretched and folded, and then filled with loose materials to form a three-dimensional rigid structure.
‌Geogrid: It is thermoplastic or molded into a two-dimensional grid shape from polypropylene, polyvinyl chloride, etc., or a three-dimensional structure with limited height.
‌Mechanical Properties‌
‌Geo Room‌:
It has strong lateral constraint capability, which can greatly improve the foundation bearing capacity and disperse load.
It has excellent anti-slip and deformation resistance, and is suitable for complex terrain (such as deserts and steep slopes).
‌Geogrid‌:
Focus on plane tensile properties and reduce deformation and cracking by enhancing soil tensile resistance.
Small creep, corrosion-resistant, suitable for conventional roadbed reinforcement and road crack prevention.
‌Application Scenarios‌
‌Geo Room‌:
Soft soil foundation reinforcement (such as desert roadbeds and river bank management).
Steep slope protection (after filling the soil, it has both solid soil and greening functions).
‌Geogrid‌:
Ordinary roadbed reinforcement and retaining wall reinforcement.
Pavement crack-resistant projects (such as road and railway grass-roots paving).
‌Economic Cost‌
The construction complexity of geogrids is slightly higher and the cost is usually higher than that of geogrids.
2. Common points
‌Material Properties‌: Both are polymer composite materials, with high strength, corrosion resistance, and long life.
Applicable fields: They are all used in civil engineering fields such as roadbed reinforcement and retaining wall engineering.
3. Summary
‌Geo-rooms are more suitable for scenarios that require three-dimensional reinforcement and complex terrain processing (such as soft foundations, steep slopes), while geogrids are more suitable for conventional projects with high demand for plane tensile resistance (such as roadbed cracking). Project selection needs to be combined with geological conditions, load requirements and cost budget.
