Geo Grid and Geo Cell for Soil Reinforcement and Erosion Control
Weak subgrades, unstable slopes, and erosion-prone embankments increase construction costs, shorten infrastructure service life, and create maintenance liabilities that compound over time. A Geo Grid transfers load from weak soil into the reinforcement layer, distributing stress across a wider area and stabilising the ground without deep excavation or mass fill replacement.
Enhance soil stability and erosion control with Geo Grid. Ideal for roads, railways, slopes and landfills. The range covers uniaxial, biaxial, triaxial, and fibre glass geogrids alongside HDPE geocells for subgrade stabilisation, slope reinforcement, retaining walls, and erosion control applications.
At Dutco Tennant LLC, we source the Geo Grid and Geo Cell system from globally proven geosynthetics manufacturers, supplying contractors, consultants, and project developers across the UAE and GCC.
Stable Ground And Lower Construction Cost
- Open aperture geometry allows aggregate particles to penetrate and interlock with grid ribs, creating a composite reinforced layer that resists lateral movement under traffic and static loading
- Reduced base course thickness achievable through reinforcement lowers aggregate consumption, excavation volume, and haulage costs on road and pavement subgrade projects
- Perforated geocell walls allow moisture and root penetration between cells, supporting vegetated infill on slope and embankment face applications where erosion control and greening are both required
- Polymer PP, PET, and HDPE construction resists acids, alkalis, fuels, salts, and biological degradation under standard installation conditions throughout a multi-decade service life
- Lightweight roll format allows manual handling and rapid deployment across large areas without mechanical spreading equipment on soft or restricted-access ground

Types
Uniaxial Geo Grid
A uniaxial Geo Grid provides high tensile strength in one primary direction, making it the standard reinforcement for retaining walls, steep slopes, and mechanically stabilised earth structures.
- Punch-and-draw HDPE manufacturing aligns molecular chains along the stretching direction, achieving high ultimate tensile strength with minimal creep under long-term sustained loading
- Horizontal layers placed between compacted fill lifts in MSE walls transfer lateral earth pressure into the reinforced fill zone, allowing near-vertical wall faces without mass concrete
- Reinforces embankments over soft ground, reducing differential settlement and lateral spreading on low-bearing-capacity subgrades during and after construction
Biaxial Geo Grid
A biaxial geogrid provides equal tensile strength in both longitudinal and transverse directions, distributing load uniformly across the subgrade under trafficked road and pavement applications.
- High flexural rigidity at rib junctions maintains aperture geometry under compaction plant loading during installation, preserving interlock performance throughout construction
- Placed at subgrade level beneath road base, biaxial grids reduce rutting, control settlement, and extend pavement service life on both paved and unpaved surfaces
- Suitable for car park subgrades, logistics yard bases, and airport apron sub-bases where differential settlement under heavy wheel loads must be controlled
Triaxial Geo Grid
A triaxial geogrid uses a triangular aperture pattern providing multi-directional in-plane stiffness, delivering the highest radial load distribution of all plastic geogrid formats.
- Triangular geometry provides load resistance across the full horizontal plane, making it the preferred choice for subgrade stabilisation under complex or multi-directional traffic loading
- High aspect ratio apertures improve aggregate interlock depth, creating a stiffer stabilised layer that reduces required base course thickness more effectively than biaxial alternatives on weak subgrades
- Specified for high-speed highway subgrades, railway sub-ballast stabilisation, and airport pavement base layers requiring long-term stiffness under repeated dynamic loading
Fibre Glass Geo Grid
A fibre glass geogrid uses high-tensile glass fibre yarns with bitumen or polymer coating, providing thermal stability and creep resistance for asphalt pavement interlayer reinforcement.
- Placed within the asphalt layer system, glass fibre geogrids arrest reflective cracking propagation from the base course through to the wearing surface, extending overlay service life
- Thermal stability across the full asphalt temperature range maintains reinforcement performance under extreme heat and cold throughout the year
- The industrial Geo Grid and Geo Cell glass fibre range is specified for highway overlay projects, bridge deck waterproofing interlayers, and airfield flexible pavement rehabilitation
HDPE Geocell
An HDPE geocell uses a three-dimensional honeycomb confinement system expanded on site and filled with soil, aggregate, concrete, or rock, creating a structurally reinforced composite layer.
- Cellular confinement prevents lateral migration of fill material under load, increasing bearing capacity without increasing the compacted density of the infill material
- Installed on slopes, geocells confine fill against downslope movement, controlling surface erosion and maintaining vegetation cover on embankments, riverbanks, and channel linings
- The commercial Geo Grid and Geo Cell solution geocell range covers base stabilisation on access roads, retaining wall construction, tree root protection zones, and load support platforms
Standout Features & Benefits
Proven Subgrade Improvement
- Geogrid reinforcement increases effective bearing capacity of weak subgrades, allowing pavement design thickness to be reduced without compromising structural performance or service life
