How much geogrid fits in a shipping container?

It swings sevenfold with strength: a 40'HQ takes about 67,200 m2 of biaxial 15/15 kN but only 9,600 m2 of 50/50 kN. Fiberglass mesh packs up to 108,000 m2. Real roll dimensions decide the landed per-m2 price.

Geogrid For Walls,
Roads & Soft Ground.

Q: What is the difference between uniaxial and biaxial geogrid?

Direction of strength. Uniaxial grids put all tensile capacity one way - into a retaining wall or slope. Biaxial grids spread strength both directions to confine road aggregate under wheel loads. Using the wrong one wastes most of what you paid for.

Q: Why does geogrid design strength matter more than the label kN?

Plastic creeps under permanent load. Wall standards divide label strength by reduction factors for creep, installation damage and durability, typically ending near half the label number. The exact factors come from each product's test data, which is why we quote both numbers.

Q: Which geogrid works for asphalt overlays?

Bitumen-coated fiberglass, often self-adhesive. Glass barely elongates and tolerates asphalt temperature, which stops old cracks reflecting through a new overlay. Check coating quality and mesh weight.

Q: Is steel-plastic geogrid any good?

For basal reinforcement of embankments on soft soil, excellent value: steel strands in a polymer jacket give very high strength per dollar with minimal creep. Check strand count and junction integrity.

The box says 100 kN. Your wall gets half. Plastic under permanent load creeps — it stretches, for decades. That's why the strength on the label and the strength your engineer can design with are two different numbers, and why the cheapest grid per kN is often the most expensive per wall. We quote both numbers, with the creep data to back them.

The Number Nobody Quotes

From Label Strength To Design Strength

Every reinforced wall standard on earth makes you divide the label strength by a chain of reduction factors: creep (plastic stretches under permanent load), installation damage (aggregate bites the ribs on compaction), and durability (chemistry, weather). The chain typically halves the number on the box — the exact factors come from each product's own test data.

Here's the trick played on buyers: a cheap grid is quoted at its ultimate strength, a branded grid at its long-term strength — and the "expensive" one wins the moment you compare the only number that holds your wall up.

We put both numbers on every quote line, and ask the mill for the creep test data. A mill that can't produce it has answered the question.

A typical uniaxial HDPE grid · illustrative chain

Ultimate strength — the label100 kN/m

÷ creep factor (30–120 yr load)~55 kN/m

÷ installation damage (compaction)~46 kN/m

÷ durability & chemistry = design strength≈42 kN/m

Factors vary by polymer and product — that's the point. Two "100 kN" grids can land at 55 and 38 after the chain. Only the test data tells you which one you're buying.

Grid To Structure

Four Grids, Four Different Jobs

"Geogrid" is four different products wearing one name. Match the structure first; the model number comes last.

Structure	Grid type	Why this one	What to check
Retaining walls & steep slopes	Uniaxial HDPE / PP 35–100+ kN one direction	All the load runs one way — into the wall. Strength goes where the tension is.	Creep data · long-term design strength
Road base & soft subgrade	Biaxial PP 15–50 kN both directions	Wheel loads push in every direction; the grid confines the aggregate like a snowshoe.	Junction strength · aperture vs stone size
Asphalt overlays (anti-reflective cracking)	Fiberglass, bitumen-coated 30–60 kN, self-adhesive option	Glass barely stretches and shrugs off asphalt temperatures — plastic can't do either here.	Coating quality · mesh weight (g/m²)
Soft-soil embankments & foundations	Steel-plastic composite very high kN, budget-friendly	Steel strands in a polymer jacket: brute strength per dollar for basal reinforcement.	Strand count · weld/junction integrity

Polyester woven grids (low creep, high strength) also available for walls where PET chemistry suits the fill.

Grades & Specifications

Uniaxial & Biaxial Geogrid: Every Grade, Every Number

Four product families — uniaxial HDPE, uniaxial PP, biaxial stretched and biaxial injection-moulded — with nominal tensile strength, strength at 2 % and 5 % strain, elongation, unit mass and aperture for every grade. Chinese mills test to JT/T 1432.1-2022; if your tender specifies ASTM D6637 or EN ISO 10319, tell us and we arrange third-party testing to that method on your batch.

Rolls 4 m wide for biaxial, up to 3 m for uniaxial, 50–100 m long by grade. Every quote names a grade from these tables and ships with the mill's batch certificate against it. Steel-plastic, polyester and fiberglass grids are on sheet 2 further down this page.

MD = machine direction (along the roll), CD = cross direction. Values are minimums per JT/T 1432.1-2022; A × B = aperture length × width. Numbers are the mill's rated values — we verify rib tensile, junction strength and aperture on your batch before loading.

The Detail That Fails First

A Grid Is Only As Strong As Its Junctions

The rib number gets all the attention, but the load transfers at the junctions — where rib meets rib. Punched-and-drawn grids are monolithic: the junction is the same plastic as the rib. Welded-strip grids depend on every weld; cheap ones let go under compaction, and the "grid" quietly becomes loose strips in the ground. The failure is invisible — the road just ruts two years early.

The second quiet detail is aperture size: the mesh opening has to suit the fill — the working rule of thumb is an aperture around 2–2.5× the mid-size stone, big enough for aggregate to strike through and lock. A perfect grid with the wrong aperture reinforces nothing. Both details are on our inspection sheet: junction pull tests and aperture check against your actual fill spec.

The Freight Angle

Strength Ships Heavy. Plan The Container First.

Geogrid freight has a brutal gradient: one 40'HQ carries 67,200 m² of light biaxial 15/15 kN but only 9,600 m² of 50/50 kN — a seven-fold spread inside one product family. Fiberglass mesh is the outlier: up to 108,000 m² in one box, which is why asphalt grid almost always ships happily.

These numbers come from our own loading tables — roll widths, diameters, weights per model — and they decide whether your per-m² landed price is pleasant or painful. We run the container plan before quoting, not after.

Rib, Junction, Coating — Tested On Your Batch

Our geogrid inspection pulls three threads: rib tensile to the rated kN, junction strength (the number cheap grids hope you never ask for), and for fiberglass, coating verification — uncoated glass loses strength fast in alkaline road environments. For wall projects we additionally chase the mill's creep test data, because that's where design strength actually comes from.

Lab sheets and inspection photos arrive before the balance payment — leverage, then payment, in that order.

Straight Answers

Geogrid Sourcing FAQ

What's the difference between uniaxial and biaxial geogrid?

Direction of strength. Uniaxial grids put all their tensile capacity one way — into a retaining wall or up a slope. Biaxial grids spread strength both ways to confine road aggregate under wheel loads. Using a biaxial grid in a wall, or a uniaxial grid under a road, wastes most of what you paid for.

Why does design strength matter more than the kN on the label?

Because plastic creeps under permanent load. Wall standards divide the label strength by reduction factors for creep, installation damage and durability — typically ending near half the label number, with the exact factors coming from each product's test data. Comparing one grid's ultimate strength against another's long-term strength is comparing apples to half-apples.

Which geogrid works for asphalt overlays?

Fiberglass — bitumen-coated, often self-adhesive. Glass barely elongates and tolerates asphalt temperatures, which is exactly what stops old cracks reflecting through a new overlay. Check the coating quality and mesh weight; uncoated glass degrades in the alkaline road environment.

Is steel-plastic geogrid any good?

For the right job, excellent value: steel strands in a polymer jacket give very high strength per dollar with minimal creep, which suits basal reinforcement of embankments on soft soil. The checks that matter are strand count and junction integrity — both on our inspection sheet.

How much geogrid fits in a container?

It swings sevenfold with strength: a 40'HQ takes about 67,200 m² of biaxial 15/15 kN but only 9,600 m² of 50/50 kN. Fiberglass mesh packs up to 108,000 m². We run the loading plan from real roll dimensions before quoting, so the landed per-m² price is a fact, not a hope.
