Lianyi®PP geogrid composite is a composite material made by combining PP geogrid (such as Biaxial geogrid made of PP,Fiberglass or Polyester)with non woven geotextile (such as polyester non woven geotextile or pp non woven geotextile through thermal lamination or adhesive bonding processes.It combines the advantages of two materials and is widely used in civil engineering,environmental engineering and other fields.
Classification Of PP Geogrid Composite
*PP Geogrid Composite With Non Woven Geotextile
Features Of PP Geogrid Composite
*High strength and tensile resistance
PP geogrid offers high tensile strength, effectively disperses loads and reduces uneven settlement of the foundation.
*Filtration and drainage
The non woven geotextile layer allows water to pass through while preventing the loss of soil particles, and it also has a drainage function.
*Anti-seepage and isolation
Some composite fabrics can be added with anti-seepage membranes (such as HDPE geomembranes for anti-seepage projects (such as landfill sites).
*Corrosion resistance and durability
Acid and alkali resistant, UV-resistant, suitable for long-term exposure or underground use.
Benefits Of PP Geogrid Composite (
*Distribution of loads and therefore reducing stress concentration over the soil.
*The geogrid’s structural junctions,rigid ribs and thick walls help lock aggregate,increasing its shear resistance. As a result when a vertical load is applied,the aggregate is restrained by the ribs reducing deformation.
*Decrease in long term deformation.
*Increase in load distribution.
Applications Of PP Geogrid Composite
*Highway/railway subgrade
*Enhance the stability of the roadbed and prevent reflective cracks.
*Slope protection
*Fix the soil in combination with vegetation to prevent landslides.
*Landfill
*Anti-seepage composite fabric is used as a cushion layer to prevent the spread of pollution.
*River course improvement
*Protect the bank slope and resist the erosion of water flow.
PP Geogrid Composite Key Points of Construction
*Laying direction: The high-strength direction of the grid must be consistent with the force direction.
*Lap treatment: The transverse lap of the grating should be no less than 10cm, and the longitudinal lap should be no less than 20cm. Geotextile lap joints need to be sewn or bonded.
*Protective layer: Avoid direct exposure to ultraviolet rays and cover the fill soil in time.
Purchase suggestions Of PP Geogrid Composite
*Select parameters such as tensile strength (e.g., above 30kN/m) and permeability coefficient (e.g., ≥0.1cm/s) according to engineering requirements.
*Give priority to well-known brands (such as Lianyi-www.geolianyi.com) to ensure quality.
