Steel-plastic Geogrid
Steel-plastic geogrid exhibits the capability to achieve an exceptionally high tensile modulus with low strain capacity, minimal creep, and the distinct advantage of breaking elongation being less than 3%. Constructed from specially treated high-strength steel wire, combined with polyethylene (PE) or polypropylene (PP), and other additives, it undergoes extrusion to form a composite high-strength tensile strip with a rough embossed surface. The strips are then vertically and horizontally braided or sandwiched at specific intervals, and the intersection points are welded using specialized fusion welding technology (ultrasonic welding technology) for enhanced bonding. This geogrid membrane is primarily employed in soft soil foundation reinforcement, as well as in applications such as retaining walls, pavement anti-crack engineering for highways, railways, bridge abutments, approach roads, docks, dams, and slag dumps.

Installing Geogrid Procedures
Using and installing the geogrid is straightforward and convenient. Below is a standard construction process.
- Begin by leveling and rolling the lower layer. The flatness should not exceed 15mm, and the compaction should meet design requirements. Strictly prohibit hard protrusions like gravel and stones on the surface.
- Laying geogrid:
① Store and lay geogrids away from sunlight and prolonged exposure to prevent performance degradation.
② Lay the geogrid fabric perpendicular to the line direction, ensuring the overlap meets design specifications. Secure knots firmly, with the connection strength in the stress direction not less than the material’s design tensile strength. Ensure an overlap length of at least 20cm.
④ Maintain continuity during construction, avoiding distortion, wrinkles, or overlaps. Tighten the grid to bear force, ensuring it is even, flat, and closely adheres to the lower bearing surface. Fix it by inserting nails and other measures.
⑤ Align the long holes with the line’s cross-sectional direction, straightening and leveling the geo grid mesh. Process the grid ends as per design.
⑥ Fill the geogrid mesh promptly after laying, with an interval not exceeding 48 hours to prevent direct sunlight exposure. - Fill symmetrically according to the “first on both sides, then in the middle” principle. Strictly avoid filling directly on the geogrid membrane; discharge on the paved soil surface with a height not exceeding 1m. Prohibit vehicles from driving directly on the geogrid layer, allowing them only along the embankment.
- After the first layer of fill soil reaches the designated thickness and is rolled to the designed density, roll up the grid, wrap it 2m back, and secure it to the previous layer of geo grid fabric. Trim and anchor manually, building 1m of soil outside the rolled end to protect the grid and prevent damage.
- After completing the first layer of geogrid paving, repeat the process for subsequent layers, following the same method and steps.
Precautions for Installation of Geogrid Layer
While the construction of geogrid mat is relatively simple, attention to the following considerations is crucial during installation. Here are specific precautions for geogrid installation:
- When laying the geogrid products, align the maximum strength direction of the geogrid with the maximum stress direction.
- When laying the geosynthetic grid, make an effort to prevent heavy vehicles from driving directly on the paved surface.
- Minimize the need for cutting and sewing of geogrids to reduce waste.
- During construction in cold weather, be aware that the geogrid fabric may become rigid, posing a risk of cuts or abrasions to hands and knees. Prioritize safety precautions during such conditions.
