Polypropylene Geogrid for Road Construction, Subgrade and Soil Reinforcement

1. Road Base Reinforcement

PP biaxial geogrid can interlock with aggregate and limit lateral movement of particles, improving the stability of the reinforced base layer.

2. Soft Soil Stabilization

For soft or low-bearing-capacity subgrades, geogrid can work with fill material to create a more stable reinforced layer and improve load distribution.

3. Improved Load Distribution

By interacting with granular materials, geogrid can distribute applied loads over a wider area and improve the performance of the road structure.

4. Reduced Lateral Aggregate Movement

The grid structure provides mechanical confinement within the aggregate layer, helping control lateral displacement under repeated loading.

5. Good Chemical Resistance

Polypropylene offers good chemical resistance and is suitable for many soil environments. Some PP geogrid products are also engineered for resistance to construction damage and environmental exposure. 

6. Multiple Tensile Strength Grades

PP biaxial geogrids are available in different strength classes, such as 15/15, 20/20, 30/30, 40/40 and 50/50 kN/m. The correct grade should be selected to meet the project design rather than simply choosing the highest tensile strength. 

Road Base Reinforcement

PP geogrid reinforces granular road bases by creating mechanical interlock with aggregate particles. It can restrict lateral movement, improve load distribution and reduce deformation under repeated traffic loads.

Soft Soil Stabilization

PP geogrid can be used in soft soils and weak subgrades to provide tensile reinforcement and improve aggregate confinement. It maintains stability where low bearing capacity makes conventional aggregate construction more difficult.

Highway and Road Construction

PP geogrid can be incorporated into road bases, subgrades and pavement structures. It is suitable for new highways, road widening and rehabilitation projects where improved reinforcement and load transfer are required.

Working Platforms and Haul Roads

PP geogrid can reinforce working platforms and temporary haul roads exposed to heavy construction traffic. It can stabilize aggregate layers, reduce lateral movement and improve ground performance under repeated equipment loading.

Yards and Parking Areas

PP geogrid can be installed within aggregate base layers for industrial yards, logistics areas and parking facilities. It improves particle confinement, load distribution and the stability of surfaces subjected to repeated vehicle loads.

Subgrade Improvement

PP geogrid can be incorporated into the pavement structure to improve stability and load transfer in weak or variable subgrades. It works with soil and aggregate to provide reinforcement and reduce structural deformation.
