Geogrid

PET Welded Geogrid

PET Welded Geogrid, made from high-tenacity PET strips via extrusion, warp-knitting and ultrasonic welding, offers high bidirectional tensile strength with minimal elongation. Its PET composition ensures corrosion resistance and low creep for long-term stability. It improves bearing capacity, controls settlement, and reduces aggregate thickness. Ideal for roadbed,wall, slope, and embankment reinforcement on soft soils.

PRODUCT DETAILS

High-Strength Material Structure

Premium PET Material & Advanced Manufacturing

Manufactured from high-tenacity PET strips arranged in a precision grid pattern with accurate spacing between warp and weft ribs. Ultrasonic welding ensures firm junction bonds that maintain structural integrity under sustained loading. The material resists chemical degradation and aging, providing durable reinforcement for long-term infrastructure projects.

Excellent Reinforcement Performance

Improving Bearing Capacity and Structural Stability

Efficiently enhances load distribution and increases subgrade bearing capacity while effectively controlling differential settlement. The geogrid interlocks with surrounding soil or aggregate materials, minimizing lateral movement and preventing base layer deformation. This results in extended pavement service life and reduced maintenance requirements.

Effective Separation and Drainage Function

Separation & Drainage Integration

Maintains effective separation between subgrade and overlying aggregate layers, preventing intermixing and preserving material integrity. The open-grid design facilitates lateral drainage, reducing pore water pressure and improving overall soil stability. This dual functionality enhances engineering performance and reduces lifecycle costs.

Versatile Application Adaptability

Wide Range of Civil Engineering Applications

Suitable for highway and railway subgrade reinforcement, retaining wall backfill stabilization, slope protection, and embankment construction over soft soils. Also effective for bridging sinkholes, stabilizing abutments, and reinforcing slag disposal areas. Available in multiple tensile strength grades to meet diverse project requirements.
