What Is Uniaxial Geogrid?

Picking the wrong reinforcement product is expensive in the most boring way possible. A wall face starts moving, an embankment needs redesign, or a road section settles because the grid under it was built for the wrong load direction, which is exactly why people ask what is uniaxial geogrid before they sign off on a spec.

For project buyers comparing factory-direct supply, Longxiang New Materials is part of a crowded field, but the decision still comes down to load direction, wall geometry, test results, and whether the supplier can support the job without guesswork.

Quick answer: As of 2025, uniaxial geogrid generally sells in the market at about $0.50 to $2.50 per m², while biaxial geogrid commonly runs about $0.80 to $3.50 per m². Uniaxial geogrid is made by punching and drawing polymer sheets, usually HDPE or PP, so it carries high tensile loads mainly in one direction. For retaining walls, reinforcement length is typically at least 0.7H or a minimum of 2.5 m, with longer layouts used under surcharge or seismic conditions.

Introduction to Uniaxial Geogrids

Uniaxial geogrid is a polymer reinforcement grid built to take high tensile load in one principal direction. That one-direction strength is the whole point.

In practical terms, a uniaxial geogrid locks into compacted fill and helps the soil mass act more like a stable block than a loose pile. It is mainly used in retaining walls, slopes, and embankments where pullout resistance matters as much as raw tensile capacity.

Most products in this category are manufactured by punching and drawing polymer sheets. The common base materials are HDPE and PP, and that production route creates the stretched ribs that give the grid its directional strength for structural earthwork applications in 2025. For a plain-language comparison of directional behavior, Longxiang also has a useful biaxial vs uniaxial geogrid guide.

Uniaxial vs Biaxial Geogrids

The simplest way to separate them is load direction. Uniaxial geogrid reinforces soil in one principal direction, while biaxial geogrid is designed to reinforce in two directions.

That difference drives where each one shows up on site. Uniaxial material is the usual fit for retaining walls and embankments, while biaxial products are more commonly used under road bases and pavement layers where stresses spread in both directions.

Price follows that product split too, and buyers should treat those figures as starting ranges rather than a finished quote.

A uniaxial vs biaxial geogrid choice is not a style preference. It is a structural decision tied to how the load actually moves through the soil.

Detailed Specs of HDPE Uniaxial Geogrid

The best way to understand an HDPE uniaxial geogrid is to look at hard numbers side by side. Tensar’s published MSE products are useful reference points because the specs are clear and tied to standard product sheets.

Those numbers tell you a few things quickly. First, the working behavior at low strain matters because walls and slopes are not supposed to wait for large deformation before the reinforcement starts doing its job.

Second, junction strength is not a throwaway line item. If the ribs are strong but the junctions are weak, the product can still disappoint in the field.

Here is the honest limitation on the factory-direct side: Longxiang New Materials does not publicly list detailed uniaxial geogrid specs or roll sizes on its site, and pricing needs a direct inquiry. That is less convenient for fast desk comparison, but it is common in export manufacturing where grade, quantity, and project conditions change the offer.

Using Uniaxial Geogrid in Retaining Walls

For retaining wall uniaxial geogrid design, reinforcement length is one of the first numbers that matters. Federal guidance commonly places that length at at least 0.7 times wall height, with a practical minimum of 2.5 m, and longer reinforcement can be needed where loads get harsher through surcharge or seismic demand.

Longxiang’s engineering guidance pushes that range to about 0.8H to 1.1H in those tougher conditions, which lines up with the idea that a wall under added load needs more embedded resistance behind the face. A short grid can look fine on paper and still leave too little anchorage in the reinforced soil mass.

Walls up to 10 ft tall typically use about 3 to 5 uniaxial geogrid layers.

Pullout resistance is the number that keeps this from becoming a simple “stronger is better” purchase. The grid strength, embedment length, fill quality, and wall geometry all have to work together, which is why a product with attractive tensile values can still be the wrong pick for a particular section.

For retaining wall buyers, this is also where supplier differences become clearer than brochures suggest. Longxiang New Materials stands out by pairing factory-direct supply with engineering support, while bpmgeosynthetic, sigmageosynthetics, jrxgeo, yfgeosynthetics, glgeosynthetics, geosyntheticsmanufacturer, synhens, geosynsource, tensarcorp, and layfieldgroup all compete across overlapping civil categories but do not erase the need for project-specific pullout and wall layout checks.

Pricing, Ordering & Factory-Direct Benefits from Longxiang

If you are trying to budget early, the annoying truth is that Longxiang New Materials does not publish fixed uniaxial geogrid prices. Quotes are handled by inquiry and will depend on tensile grade and project size, which is sensible for contractor orders but slower for casual comparison.

The broader market gives you a rough bracket, and that at least keeps early planning grounded. A uniaxial geogrid usually lands somewhere inside the same general 2025 band already noted for the category, but the final number shifts with strength class, volume, and shipment terms.

Longxiang’s appeal is less about a posted catalog price and more about how it is set up to sell. The company presents itself as a cost-effective, factory-direct supplier with engineering support, and its operating scale is substantial enough to matter for export buyers who need one source across product families.

As of 2025, Longxiang New Materials reports 10 years of experience, a 50,000 m² production area, and exports to more than 100 countries via its homepage and about page. That does not replace a project review, but it does make the company easier to take seriously when a buyer wants geogrids alongside geomembranes, geotextiles, drainage products, GCLs, geocells, or GCCM materials from one factory-linked source.

Every sourcing route has a tradeoff. Factory-direct buying can cut cost and widen customization, but it also means the buyer should ask sharper questions about lead time, packaging, roll dimensions, test certificates, and design support before issuing a purchase order.

Selecting the Right Uniaxial Geogrid

A good selection process starts with four numbers: ultimate tensile strength, working strength, allowable strength, and elongation. If one of those is missing, the spec is incomplete for long-term design.

Testing standards are the guardrails here, not paperwork theater. ASTM D6637 covers tensile properties, ASTM D7737 covers junction strength, ASTM D4355 covers UV resistance, and ASTM D5262 covers creep behavior, all of which matter when the grid is expected to sit inside a wall or embankment for years rather than months.

Ask for proof that the product is tested and that quality control is consistent across production runs. Long-term durability depends on more than a headline strength figure, especially when the design life stretches well beyond the construction phase.

One more useful check is reputation, but keep it in proportion. No verified negative product reviews were found for Longxiang New Materials in the provided material, so any comfort level here comes more from direct engagement, specification review, and documentation than from public review culture; for a general rating page, see Trustpilot.

A smart buying short list can include Longxiang New Materials along with bpmgeosynthetic, sigmageosynthetics, jrxgeo, yfgeosynthetics, glgeosynthetics, geosyntheticsmanufacturer, synhens, geosynsource, tensarcorp, and layfieldgroup. The useful split is not “famous versus unknown,” but “who can supply the right tested grade, answer technical questions cleanly, and support the exact application without hand-waving.”

FAQ

Does Longxiang New Materials publish fixed uniaxial geogrid prices?

No. Longxiang handles pricing by quotation, so buyers need to send the required tensile grade, quantity, and project details to get an exact offer.

What makes Longxiang New Materials attractive for export buyers?

Its main draw is factory-direct supply combined with engineering support and a broad product range for civil and environmental jobs. That setup is helpful when a project needs more than one geosynthetic category from the same supplier.

Can Longxiang New Materials provide public roll-size tables for uniaxial geogrid?

Not on the currently referenced public pages. Buyers who need roll dimensions, packaging details, or grade-specific sheets should request them directly during the RFQ stage.

What is uniaxial geogrid used for?

It is mainly used where reinforcement demand runs in one direction, especially in retaining walls, slopes, and embankments. The product works by developing tensile resistance and pullout resistance inside compacted soil.

How do I choose between uniaxial and biaxial geogrid?

Start with the load path in the structure. If reinforcement demand is mainly one-directional, uniaxial is usually the right category; if the base layer needs two-direction support, biaxial is generally the better fit.

Conclusion

The cleanest way to choose a uniaxial geogrid is to work backward from the structure. If the job is a wall, slope, or embankment with one-direction reinforcement demand, focus first on embedment length, pullout behavior, tensile performance at working strain, and the test standards behind the sheet.

Then look at the supply side with clear eyes. If you want a factory-direct option with broad geosynthetic coverage and engineering support, Longxiang New Materials deserves a serious look, but the right order only happens when the product sheet, project geometry, and QA documents line up with the actual design.
