Biaxial PP Geogrid 20-80 kN/m (2,900-11,600 lb/ft) with 20x20-50x50mm (0.8x0.8-2x2 in) Apertures for Highway Railway Airport Parking Lot Soft Soil Foundations
Significant Cost Reduction: Reduces the required aggregate base thickness by up to 30%, significantly lowering material and transportation costs for parking lots and soft soil foundations.
Accelerated Construction: Cuts project timelines by up to 50% compared to traditional soil stabilization methods, as the lightweight PP rolls are easy to handle and install.
Extended Infrastructure Lifespan: Increases pavement fatigue life by 8-12 years by mitigating differential settlement and preventing reflective cracking in high-traffic zones.
Exceptional Soil Interlock: Features precisely engineered 20x20-50x50mm (0.8x0.8-2x2 in) apertures that create a highly efficient mechanical lock with surrounding aggregates.
Chemical & Biological Resistance: Manufactured from high-quality Polypropylene (PP) with UV stabilizers, ensuring resistance to soil acids, alkalis, and long-term environmental degradation.

Key Technical Advantages
⚙️ Biaxial Molecular Orientation: Manufactured through a precise extrusion, punching, and biaxial stretching process, ensuring equal and high tensile strength in both the longitudinal and transverse directions.
🔗 Advanced Aggregate Interlocking System: The rigid, rectangular rib structure and uniform apertures confine aggregate particles, creating a stiffened composite layer that acts as a semi-rigid slab to distribute vertical stresses.
🛡️ Low Creep & High Modulus: Engineered with a high modulus and low elongation rate (typically ≤13% longitudinal / ≤16% transverse at yield), ensuring the geogrid maintains its structural integrity under continuous heavy loads without excessive deformation.
📉 Optimized Aperture Geometry: The 20x20-50x50mm (0.8x0.8-2x2 in) square openings are specifically designed to maximize the passive resistance and friction coefficient between the geogrid and the soil/aggregate fill.
🌍 Robust Durability Formulation: Premium PP material is treated with carbon black and anti-aging additives, providing superior resistance to ultraviolet radiation, extreme temperatures, and harsh chemical environments.

Application Solutions🛣️ Highway & Railway Embankments
Challenge: Heavy dynamic loads from high-speed trains and trucks cause lateral spreading of the base aggregate, leading to rutting, differential settlement, and frequent maintenance.
Solution: Biaxial PP geogrids act as a tensioned membrane within the base course, confining the aggregate and distributing wheel loads over a wider area. This reduces base thickness requirements and extends the maintenance interval of the transportation infrastructure.
✈️ Airport Runways & Taxiways
Challenge: Extreme point loads from aircraft landing gear and strict safety tolerances require highly stable foundations that resist deformation and fatigue cracking.
Solution: The high-strength interlocking system creates a stiffened working platform that prevents subgrade intrusion into the base course. This ensures long-term dimensional stability and significantly reduces the risk of reflective cracking in asphalt pavements.
🅿️ Heavy-Duty Parking Lots
Challenge: Constant braking, turning, and static loads from heavy vehicles cause severe shear stress, leading to rutting, potholes, and premature pavement failure.
Solution: Integrating biaxial geogrids into the parking lot sub-base absorbs shear stresses and prevents lateral movement of the aggregate. This enhances the load-bearing capacity of the lot while reducing the required depth of imported fill.
🏗️ Soft Soil Foundations
Challenge: Building on weak, compressible soils often results in severe uneven settlement, bearing capacity failure, and costly, time-consuming soil replacement or pre-loading processes.
Solution: The geogrid provides immediate basal reinforcement, bridging over soft spots and distributing structural loads across a larger footprint. This stabilizes the subgrade, accelerates consolidation, and allows for safe construction without extensive soil excavation.
