What it is
High-Strength Geogrid for Soil Reinforcement
A uniaxial geogrid is engineered to carry load in one direction — its machine direction — which is exactly what a reinforced soil mass needs. TenCate Miragrid® XT grids are polymer-coated woven polyester, built for the tensile demands of retaining walls, steepened slopes, and landfills.
They deliver high long-term design strength (LTDS), excellent creep resistance, and strong soil interaction, while staying light and flexible enough to handle and connect on site. That makes them a cost-effective choice for both temporary and permanent Mechanically Stabilized Earth (MSE) structures.
Sizing a wall or slope? Match the right XT strength to your design load with the Geogrid Spec Finder.
01
Where Uniaxial Geogrid Is Used
Applications
Retaining Walls
Reinforces the soil mass behind segmental (SRW) and MSE block walls for stable, tall structures.
Steepened Slopes
Lets you build slopes steeper than the soil's natural angle without a facing wall.
Bridge Abutments
Reinforced fill for load-bearing abutments and approach embankments.
Landfills & Embankments
Base reinforcement and veneer stability for cells, berms, and embankments over soft soils.

Why Miragrid XT
Performance
Long-term strength
High LTDS
High long-term design strength carries load for the full service life of a permanent structure.
Stays put
Creep Resistant
Woven polyester resists stretching under sustained load, holding the reinforced mass in place.
Grip
Soil Interaction
The coated grid structure locks into backfill for strong pullout resistance and connection.
On site
Light & Flexible
Easy to handle, cut, and connect between wall blocks — faster placement than stiff grids.

Case Studies — Miragrid XT in the Field
3 projects
A 28-Foot Wall to Extend an Airport Runway
Keystone Compac blocks with Miragrid® XT geogrid built a structurally sound, aesthetically appealing wall that let Manchester-Boston Regional Airport lengthen its runway.
The objective
An airport expansion needed to extend the runway, but the existing entrance roadway held back the available land. A retaining wall was required to reclaim it.
The design
A segmental retaining wall of Keystone Compac blocks reinforced with Miragrid® XT geogrid — required to be both structurally sound and visually clean.
The result
The finished wall reached 28 feet, with tiered 14-foot sections merging into a third wall — roughly 100,000 sq ft of frontage, a strong alternative to poured concrete.
A 43-Foot Tiered MSE Wall for a Headquarters Access Road
A Keystone wall system reinforced with Miragrid® 3XT, 5XT, and 8XT solved a 75-foot grade change to carry a new access road into Tesoro's headquarters site.
The objective
The access road faced a 75-foot elevation drop with limited space — a steepened slope wasn't possible, so a retaining wall was required on the east side.
The design
A Keystone wall was chosen for its height-to-depth ratio and looks. Miragrid® 3XT, 5XT, and 8XT were specified for their long-term and creep-reduced strength and block connection.
The result
Built as a three-tiered system up to 43 feet tall. The grids' flexibility let the contractor connect between blocks easily; the wall met load and aesthetic goals on time.
Soil-Nail and SRW Walls for a Retail Development
A hybrid soil-nail and segmental-wall design using Miragrid® geogrid created parking for new retail while keeping the service road above the site open.
The objective
A shopping-center owner needed parking for new tenants while preserving the existing road above — with significant grade problems behind the wall line.
The design
Soil nails were drilled into the steepest cut areas with geogrid tied to a header beam; standard SRW geogrid design was used across the fill areas.
The result
The approach maximized the usable footprint while keeping traffic flowing, and let the developer vary block style and texture across the project.
Common questions
Uniaxial Geogrid — Frequently Asked Questions
What is a uniaxial geogrid?
A uniaxial geogrid is a geosynthetic reinforcement designed to carry tensile load in one primary direction (its machine direction). That single-direction strength is ideal for reinforced soil structures like retaining walls and slopes, where the load pulls in one direction. Miragrid® XT grids are polymer-coated woven polyester.
What's the difference between uniaxial and biaxial geogrid?
Uniaxial geogrid is strongest in one direction and is used for soil reinforcement — retaining walls, steepened slopes, and MSE structures. Biaxial geogrid carries load in two directions and is used mainly for base stabilization under roads and working platforms. If you're reinforcing a wall or slope, you want uniaxial.
Do I need geogrid for a retaining wall?
Most segmental retaining walls above about 3–4 feet need geogrid reinforcement to stay stable, and taller or surcharged walls almost always do. The exact requirement depends on wall height, soil, and loading, and should follow the wall engineer's design. Use the Geogrid Spec Finder to match a Miragrid XT strength to your design values.
How far back should geogrid extend into the soil?
Geogrid embedment length is set by the wall design — it depends on wall height, soil properties, and loading, and is typically a percentage of the wall height. Follow the reinforcement lengths on your engineered wall drawings rather than a rule of thumb.
What do the Miragrid XT numbers mean?
The number reflects the grid's strength — higher numbers carry more load. The line runs 3XT, 5XT, 7XT, 8XT, 10XT, 20XT, 22XT, and 24XT, so you can match the grade to your design's required long-term strength. All ship by the roll with free shipping.
