The High-Density Polyethylene (HDPE) Single-Directional Stretch Geogrid is made from HDPE material, which undergoes plastic extrusion into sheet material, punching, heating, and stretching. The stretching process reorients the originally disordered chain molecules into a linear state, fully demonstrating the geogrid's tensile strength and rigidity. When laid in the soil, the geogrid's mesh interacts with the soil, forming a stress transfer mechanism that rapidly and effectively spreads local loads over a large area of soil, thereby reducing local destructive stress and enhancing the service life of the engineering project.

The outstanding advantage of the polyethylene单向拉伸geotextile格栅 lies in its minimal tendency to deform (creep) under long-term sustained loads, exhibiting significantly higher creep resistance than other geotextile materials. This plays a crucial role in extending the service life of engineering projects.

This product is suitable for reinforcing retaining walls, embankments, bridge decks, steep slopes, and geotextile cells for road, railway, and riverbank construction. Its functions include withstanding the bearing capacity of retaining walls or embankments, extending service life, reducing land occupation, shortening construction time, lowering costs, and minimizing maintenance expenses.

Geosynthetic格栅, which is stretched unidirectionally, is produced by extruding high molecular polymer into a thin plate and then punching it into a regular grid pattern, followed by stretching it longitudinally. This process aligns the polymer into a directional linear state, forming a uniform, high-node-strength, elongated oval mesh structure. This structure boasts high tensile strength and modulus, with our company's products particularly exhibiting ultra-high early-stage (elongation of 2-5%) tensile strength and modulus, surpassing international standards. It provides an ideal force-bearing and diffusing连锁 system for soil. The product has a high tensile strength (>150Mpa), is adaptable to various soils, and is widely used as a reinforced material for soil reinforcement.

Purpose:

Geotextile Stretchable Geogrid is a high-strength geosynthetic material. It is widely used in embankments, tunnels, docks, highways, railways, and construction fields.

The primary applications include:

1. Reinforced subgrade effectively distributes and disperses loads, ensuring stability and bearing capacity of the subgrade, thereby extending its service life.

2. Capable of withstanding greater alternating loads.

3. Prevent subgrade material loss, thereby avoiding subgrade deformation and cracking.

4. Enhances the self-supporting capacity of backfill behind retaining walls, reduces soil pressure on the retaining wall, saves costs, extends service life, and lowers maintenance expenses.

5. Integrating shotcrete construction techniques for slope maintenance not only saves 30-50% of investment but also cuts the construction period by more than double.

6. Adding geogrids to the subgrade and surface of highways can reduce settlement, decrease rutting, and delay the appearance of cracks by 3 to 9 times, potentially reducing the thickness of the structural layer by up to 36%.

7. Suitable for various soils, eliminating the need for off-site materials, saving both labor and time.

Installation is simple and quick, significantly reducing construction costs.
