PP Composite Geogrid

What’s PP Composite Geogrid? 

Lianyi®PP Composite Geogrid is made up of biaxial geogrid-Polypropylene through the process of extruding, longitudinal and transverse heat stretching.Nonwoven Geotextile is then heat bonded to the grid to form a sound composite structure.PP Composite Geogrid is designed to prevent reflection cracking, water damage and improve load capacity in road construction and renovation.

PP Composite Geogrid has the property of high temperature resistance and anti-fatigue cracking and therefore extending the life and time of asphalt pavements.

Features Of PP Composite Geogrid  

*High tensile strength from 15-15kN/m to 50-50kN/m

*Good elongation ≤13%

*Mesh size: 33*33mm,36*36mm,39*39mm,65*65mm

*High strength junctions and stiff ribs

*Good integrity,high node strength

*Stable performance,strong resistance to microorganisms and corrosion

Advantages Of PP Composite Geogrid  

*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 Composite Geogrid  

*Base reinforcement

*Subgrade reinforcement 

*Pavement stabilisation

*Subgrade separation

*Embankment stabilisation

*Slope stabilisation
