Product Introduction
Uniaxial geogrid is a high-strength geosynthetic material specifically designed for uniaxial stress environments. It is primarily made from stretched polymers (such as high-density polyethylene (HDPE) or polypropylene (PP), possessing extremely high uniaxial tensile strength and stiffness.
If a lawn paving mat is a planar, lateral distribution of pressure, then a uniaxial geogrid is more like the **"bones and ribs"** of the soil, specifically designed to withstand lateral or slope-related tensile forces.
Working Principle
1. Working Principle: The Soil's "Reinforcing Steel" Soil itself has strong compressive strength but extremely poor tensile strength. The working principle of uniaxial geogrid is based on the following three points:
Interlocking and Friction: The mesh of the geogrid is relatively large, allowing filler soil (sand, gravel, or earth) to pass through and become embedded within. When the soil attempts to move, the transverse ribs of the geogrid act like anchor piles, locking the soil particles and generating significant frictional resistance and interlocking force.
Tensile stress transfer: When soil is loaded or experiences a landslide due to gravity, the resulting tensile force is absorbed by the geogrid and transmitted along its long axis. This is similar to adding steel reinforcement to concrete, transforming the originally unstable loose soil into a "reinforced soil composite" with tensile strength.
Lateral displacement restraint: It effectively restricts the lateral movement of soil particles, increasing the overall stability of the soil.
2. Core characteristics: Unidirectional stress
Shape characteristics: It presents a rectangular, elongated perforated shape. Its longitudinal (production direction) ribs are very thick and extremely strong, while the transverse ribs are relatively thin, serving only to connect and maintain the shape.
High performance indicators: It has excellent creep resistance (not easily deformed under long-term stress) and corrosion resistance, with a design service life typically ranging from 50 to 120 years.

Application Case
Application
Main application scenarios: Unidirectional geogrids are best suited for handling **"vertical or steep"** civil engineering projects:
Reinforced retaining walls (MSE Walls): This is the most classic application. Layers of geogrid are laid behind retaining walls, using the weight of the soil to press down on the geogrid, which in turn pulls the wall surface, allowing for the construction of extremely high and vertical walls.
Steep Slope Reinforcement: If the slope of a natural mountain or embankment exceeds the soil's stability angle (usually over 30°), laying unidirectional geogrid can prevent landslides and even achieve greening of slopes steeper than 70°.
Bridge Abutment Reinforcement: Used for reinforcing the backfill at the junction of bridges and roads, reducing settlement and preventing "bounce" phenomena.
Dams and Embankments: Enhances the overall shear strength of dams in hydraulic engineering projects.
