Uniaxial Geogrids – High-Strength Soil Reinforcement for Walls & Slopes

Uniaxial geogrids carry tensile load in one principal direction, making them the standard reinforcement for retaining walls, reinforced slopes, bridge abutments and embankments. Fill material interlocks with the open apertures, transferring load from the soil into the geogrid.

Tensar® RE and Tensar® UX geogrids are made by extruding, punching and drawing a single homogeneous HDPE sheet, so the product needs no weaving, coating or welding to hold together. This process forms integral junctions with high strength, allowing reliable connections between geogrid rolls and to facing units such as modular blocks and concrete panels.

MIRAGRID® GX geogrids are knitted from high-tenacity polyester yarns and protected by a black polymeric coating. They combine high tensile strength with low creep, and their wide rolls cover large walls, slopes and embankments with fewer overlaps.

TechGrid TGU geogrids, manufactured by TechFab, are formed from high-tenacity polyester yarns into a dimensionally stable grid with uniform apertures using weft-insertion warp knitting, then finished with a durable polymeric coating that resists installation damage. Available in grades from 40 to 600 kN/m and supplied in 5.1 m × 100 m rolls, the range is designed for a 120-year service life.

Choosing between HDPE and polyester depends on the structure and the fill. HDPE grids are typically preferred where connection strength to the facing is critical, and where fills fall outside the pH 5–9 range, such as lime- or cement-treated soils. Knitted polyester grids offer low creep and wide rolls that speed up placement on large walls and slopes. Our engineers can help you select the right range and grade for your design. For high-strength applications such as basal reinforcement of embankments over soft soils, TechGrid TGU is available up to 600 kN/m.
