Product Overview
Geogrid is a high-performance geosynthetic reinforcement material manufactured from polypropylene (PP), high-density polyethylene (HDPE), or polyester (PET) through extrusion, stretching, or weaving processes. It combines exceptional tensile strength with an open grid structure to interlock with soil, aggregate, or rock for superior load distribution.
How does Geogrid soil reinforcement work?
The core mechanism of geogrid reinforcement is mechanical interlock. Soil or aggregate particles penetrate the geogrid apertures and become confined, creating a composite layer with dramatically increased bearing capacity. This interlocking effect distributes loads over a wider area, reducing stress on the subgrade below.
Liaoning Hengyu utilizes advanced extrusion and biaxial stretching technology to produce geogrids with uniform aperture geometry and consistent tensile strength in all directions, strictly adhering to GB/T 17689-2008 standards to guarantee reliable performance in every roll.
Our geogrids offer excellent UV resistance, chemical stability, and long-term creep resistance, remaining structurally sound under sustained load in a wide range of soil and environmental conditions — making them the preferred choice for permanent ground reinforcement projects.
Typical Applications
- Road base and subgrade stabilization for highways and airport runways
- Retaining walls and steep slope reinforcement for embankments
- Railway track bed reinforcement and ballast confinement
- Soft ground improvement and foundation reinforcement
- Landfill base reinforcement and waste containment structures
- Mining haul roads and heavy-load industrial yard stabilization
Core Advantages of Geogrid
Our Geogrid offers outstanding soil reinforcement and load distribution performance for road construction, retaining walls, embankments, and heavy-duty ground stabilization.
High Tensile Strength
Manufactured through biaxial stretching or weaving, our geogrids achieve tensile strength up to 200kN/m, providing exceptional load-bearing capacity for heavy infrastructure and permanent reinforcement applications.
Superior Interlocking Effect
The open aperture structure allows soil and aggregate particles to interlock firmly within the grid, forming a stable composite layer that dramatically increases bearing capacity and reduces subgrade deformation.
Fast & Simple Installation
Lightweight rolls and straightforward unrolling installation significantly reduce labor costs and construction time. No special equipment is required — simply roll out, cut, and compact with fill material.
Excellent Durability
Made from chemically inert PP or HDPE materials, our geogrids resist corrosion, biological degradation, UV exposure, and a wide range of soil pH levels, ensuring reliable performance over decades of service life.
Low Creep Deformation
Optimized molecular orientation through precision stretching minimizes long-term creep under sustained load, maintaining structural integrity and reinforcement efficiency throughout the design life of the structure.
Project-Specific Specs
Available in aperture sizes 20mm – 80mm with tensile strength from 30kN/m to 200kN/m. Liaoning Hengyu provides Biaxial, Uniaxial, and Fiberglass Geogrid types to meet specific project load and soil conditions.

Geogrid – Frequently Asked Questions
Q1: How do I choose between Biaxial and Uniaxial Geogrid?
Selection depends on the direction and nature of the load in your application. Biaxial Geogrid distributes load equally in both longitudinal and transverse directions, making it ideal for road base stabilization, foundations, and general subgrade reinforcement. Uniaxial Geogrid is optimized for single-direction tensile strength, making it the preferred choice for retaining walls, steep slopes, and embankment reinforcement where the primary stress acts in one direction.
Q2: Does your Geogrid meet international engineering standards?
Absolutely. Our Geogrid is manufactured in strict accordance with JT/T 480-2002 and JT/T 1432.1-2022 Chinese standards, and also complies with ASTM D6637 and ISO international requirements. We can customize tensile strength (30kN/m–150kN/m), aperture size, and roll dimensions to match your specific tender specifications or local national requirements.
Q3: What are the storage requirements for Geogrid during shipment?
Geogrid rolls should be stored away from direct sunlight and heat sources to preserve UV stabilizer integrity. Liaoning Hengyu wraps all export rolls in UV-resistant polyethylene film for full protection during transit. We typically deliver within 10–15 days, ensuring rolls arrive in perfect condition and ready for immediate deployment on site.
Q4: Can we request a Geogrid sample for laboratory testing?
Yes, we provide free Geogrid samples (approx. 0.5m × 0.5m) for your quality appraisal and in-house tensile testing. For large-scale pilot projects, we can also arrange small trial rolls. Please provide your courier account (DHL/FedEx) for freight collection, and we will include a full Technical Data Sheet (TDS) and our latest factory test reports in the package.
