Lianyi®PP welded geogrid(polypropylene welded geogrid) is a kind of geosynthetic material with a mesh structure made mainly of polypropylene (PP) through hot-melt welding technology. It features light weight, corrosion resistance and low cost, and is widely used in fields such as roadbed reinforcement, slope protection and water conservancy projects.
*Lightweight and high strength: Moderate tensile strength (20 to 100kN/m), light weight, convenient for transportation and construction.
*Chemical resistance: PP material is resistant to acids, alkalis, salts and microbial erosion, and is suitable for damp or chemically polluted environments
*Good flexibility: Compared with steel-plastic grating, PP grating has a stronger deformation capacity and can adapt to uneven settlement.
*Low cost: The raw material prices are relatively low, and its economic efficiency is superior to that of PET or glass fiber geogrid.
*UV resistance (optional) : By adding UV inhibitors, the outdoor service life can be prolonged.
*Environmentally friendly and recyclable: PP material can be recycled and reused, meeting the requirements of sustainable development.
Common Types Of PP Welded Geogrid
It has high longitudinal strength but low transverse strength, and is suitable for unidirectional force-bearing projects such as retaining walls and steep slope reinforcement.
The strength is balanced in both longitudinal and transverse directions, making it suitable for scenarios that require uniform force distribution, such as soft foundation treatment and roadbed reinforcement.
Embed fibers or grids in the PP substrate to enhance the overall strength.
Application Of PP Welded Geogrid
*Reinforcement of highway/railway subgrades
*Reduce settlement and prevent road surface cracking.
*Slope protection and ecological restoration
*Combined with grass planting net pads, it is used for greening slope projects.
*Soft soil foundation treatment
*Enhance the bearing capacity of the foundation and prevent lateral displacement.
*River slope protection and embankment reinforcement
*Strong water resistance, suitable for water conservancy projects.
*Protection of anti-seepage layers for landfill sites and tailings ponds
*As a reinforcing layer, it protects the anti-seepage membrane.
