What’s Steel Plastic Geogrid Composite Geotextile?
Lianyi®Steel plastic geogrid composite geotextile is a high-performance geosynthetic material manufactured through advanced composite technology. It perfectly combines the high strength of steel plastic composite geogrid with the multi-functionality of geotextile, achieving an integrated function of “reinforcement, isolation, filtration and drainage”.Steel plastic geogrid composite geotextile has outstanding advantages such as fast construction, reliable quality and high comprehensive benefits, and is an important tool for solving complex foundation problems in modern civil engineering construction.
Core Structure and Composition
This material is usually composed of a three-layer structure, like a “sandwich” :
1.Core layer (reinforcing layer) : steel plastic composite geogrid
Material: With high-strength steel wire or iron wire as the core, and wrapped with polyethylene (PE) or polypropylene (PP) plastic on the outside to prevent corrosion.
Function: It provides extremely high tensile strength and shear strength at nodes, serving as the “skeleton” of the material and undertaking the primary reinforcing function.
2.Upper and lower layers (functional layer) : geotextile
Material: Usually needle punched nonwoven geotextile (polyester or polypropylene).
Function: It provides isolation, filtration, drainage (reverse filtration), protection and other functions.
3.Composite process
Geotextiles are firmly bonded to one or both sides of the steel plastic composite grid through processes such as thermal lamination, adhesive bonding or needling
Advantages Of Steel Plastic Geogrid Composite Geotextile
1.Integrated functions, effect 1+1>2:
*Reinforcement + isolation: One-time laying, simultaneously achieving the functions of reinforcement and stability as well as preventing the mixture of different soil layers.
*Reinforcement + filtration and drainage: While reinforcing, ensure that water in the foundation can be smoothly discharged laterally without soil particles being lost, maintaining the long-term stability of the structure.
2.Convenient construction and controllable quality
*The cumbersome process of laying geogrid and geotextiles layer by layer on site has been eliminated, and the construction efficiency has been greatly improved.
*Steel plastic geogrid composite geotextile avoids problems such as inaccurate positioning and material damage that may occur during on-site laying, making it easier to ensure the quality of the project.
*The integrated structure is easier to tension during laying and can immediately exert a reinforcing effect.
3.Performance enhancement
*Geotextile provides certain additional protection for the plastic coating of steel plastic geogrid
*The integrity after compounding is better, and the interlocking friction force with the soil is greater.
Applications Of Steel Plastic Geogrid Composite Geotextile
*Soft soil foundation treatment: Steel plastic geogrid composite geotextile is used for soft foundations in highways, railways, airports, ports, etc., to enhance bearing capacity and prevent settlement and collapse.
*Reinforced soil retaining wall/slope: As a reinforcing material,Steel plastic geogrid composite geotextile also ensures smooth drainage behind the wall, making it an ideal choice for constructing high and steep, stable structures.
*Reinforcement of embankments and riverbanks: Enhance the stability of embankments while preventing soil erosion.
*Large station foundations: such as container yards, logistics parks, parking lots, etc., bear heavy and repeated loads.
*Environmental protection projects: such as the base layer of landfill sites and the covering system for site closure, need to have the functions of reinforcement, isolation and protection simultaneously.

What’s Steel Plastic Composite Geogrid?
Lianyi®Steel plastic composite geogrid is a geosynthetic material with high-strength steel wire (or other metal wire) as the core load-bearing material, wrapped with plastic protective layers such as polyethylene (PE) or polypropylene (PP) on the outside, and made into a geogrid-like structure through precise processes (such as welding)
Steel plastic composite geogrid design ingeniously combines the high strength of metal with the corrosion resistance of plastic,the popular type 100-100kN/m,mesh size 75*75mm.
Features Of Steel Plastic Composite Geogrid
*Core force-bearing unit: The steel wire inside. This endows the grating with extremely high tensile strength (typically up to over 100 kN/m, far exceeding that of pure plastic geogrid)
*Protective layer: The plastic covering the outside.Its main function is to prevent corrosion and rust, ensuring that the internal steel wire can work stably for a long time in damp, acidic or alkaline soil environments and extending its service life.
*Node structure: Steel wires are strongly welded at the intersection points to form a firm and rigid node. This is the key to the superior performance of steel-plastic composite geogrid, It can ensure that it will not tear at the point of force application, and the force can be effectively transmitted and dispersed
.
Advantages Of Steel Plastic Composite Geogrid
Compared with pp geogrid, fiberglass geogrid,etc., steel plastic composite geogrid have the following outstanding advantages
*Ultra-high strength and low creep: It has extremely high tensile strength and small deformation (low creep) under high loads, providing long-term stable reinforcement.
*Outstanding durability: The plastic coating effectively resists chemical and electrochemical corrosion in soil and water, with a long designed service life.
*Rigid nodes with strong interlocking force: The interlocking and interlocking effect with the soil is excellent, which can maximize the self-strength of the soil and form a stable complex.
*Easy to install: It is relatively light in weight, easy to cut, connect and lay.
Applications Of Steel Plastic Composite Geogrid
The core function of steel plastic composite geogrid is “reinforcement”, that is, it utilizes its high tensile strength to withstand tensile stress in the soil, thereby enhancing the stability and load-bearing capacity of the soil. Mainly applied to:
1. Soft soil foundation treatment
*Scene: Soft foundations beneath highways, railways, airports, and port terminals.
*Function: Disperse the load, reduce uneven settlement, and prevent pavement cracking.
2. Reinforced soil retaining wall
*Scene: Cutting or embankment retaining walls of highways and railways, landscape retaining walls.
*Function: As a reinforcing bar, it works in conjunction with the panel and backfill soil to form stable upright or steep walls, saving land and earthwork.
3. Slope reinforcement and slope protection
*Scene: Roadbeds, reservoirs, and slopes of rivers.
*Function: Enhance the stability of slopes, prevent landslides and erosion, and allow for the construction of steeper slopes.
4. Large-scale ground foundation reinforcement
*Scene: Container yard, logistics park, parking lot, freight yard.
*Function: It can withstand the repeated loads of heavy containers and vehicles, prevent ground subsidence and surface layer damage.
