Geogrids & Interlayers
Geogrids and asphalt interlayers for roads, working platforms, reinforced soil walls and slopes across Africa. Product supply, delivery, installation and documented QA/QC coordinated to your project scope.
| About Geogrids & Interlayers
Choose the system by its engineering function. Stabilisation geogrids restrain aggregate in road foundations and working platforms. Soil-reinforcement geogrids provide tensile reinforcement in designed walls, slopes and embankments. Asphalt grids, paving composites and paving fabrics serve the pavement rehabilitation layer. These functions require different design checks and installation methods.
Our range includes Tensar® stabilisation and reinforcement geogrids, Solmax MIRAGRID® reinforcement products, glass fibre asphalt grids and paving interlayers. Send the drawings, ground conditions, loading and specified product grade so we can confirm the appropriate material, current technical documentation, quantities and delivery arrangements. Installation and QA/QC are agreed against the approved design and manufacturer’s guidance.
| Common Applications and Engineering Use Cases
Working Platforms & Mine Access
Product selection for trafficked platforms and access routes, based on ground conditions, loading and aggregate.
Read MoreReinforced Soil Structures
Tensile reinforcement in approved wall, slope and embankment designs.
Read MoreSlope & Erosion Protection
Reinforcement is selected as part of the designed slope system; erosion control and drainage requirements are considered separately.

| Property | Engineering Function | Selection & Verification |
|---|---|---|
| Stabilisation geogrids | Aggregate restraint in roads and platforms | Manufacturer design method, aggregate and ground conditions |
| Soil-reinforcement geogrids | Tensile reinforcement in walls, slopes and embankments | Long-term design strength, fill interaction and connections |

| Asphalt interlayers | Overlay reinforcement, stress relief or moisture barrier | Product type, pavement preparation, tack coat and overlay design |
| Types of Geogrids & Interlayers
Biaxial Geogrids
Grids with ribs in two principal directions, selected for the specified granular-layer function and manufacturer design method. Ground conditions, aggregate and loading determine the system; tensile rating alone does not establish road performance.
Tensar® TriAx® Geogrids
Tensar® TriAx® uses triangular apertures to stabilise designed aggregate layers. Select the grade, layer arrangement and installation requirements using Tensar’s product-specific guidance.
Tensar® InterAx® Geogrids
InterAx® is a distinct Tensar stabilisation family for aggregate layers, trafficked surfaces and foundations. Retain the specified grade and design method; do not infer equivalence from another grid’s nominal tensile strength.
Uniaxial Geogrids
Reinforcement with a primary tensile direction for designed walls, slopes and embankments. Confirm grade, long-term design strength, fill interaction, orientation and connections against the approved design.
Composite Geogrids
Reinforcement combined with a geotextile component. MIRAGRID® PEC uses polyester reinforcement and nonwoven geotextile; confirm the required functions and grade for the selected system.
TechLink Strip Bonded Geogrids
TechLink is a soil-reinforcement grid made with polymeric strips bonded at their crossing points. Use the exact specified grade and manufacturer data for basal reinforcement, walls or other approved structural applications.
TechStrap Polymeric Geostrips
TechStrap uses polyester reinforcement within a polymer sheath for designed reinforced-soil wall systems. Reinforcement length, grade and facing connections are determined by the approved wall design.
Glass Fibre Asphalt Grids
Glass fibre grids are used within specified asphalt reinforcement systems. Confirm the product grade, existing pavement preparation, tack coat and overlay arrangement.
Asphalt Interlayer Composites
Paving composites combine reinforcement with a geotextile component. Their reinforcement, bonding and moisture-barrier functions depend on the selected product and correctly specified installation.
Paving Fabric — SAMI
Bitumen-saturated nonwoven paving fabric, including TechPave, provides a stress-absorbing interlayer and moisture barrier within an approved asphalt-overlay system. Confirm binder application and pavement preparation for the exact product.
| Benefits of using Geogrids & Interlayers
Aggregate Interlock and Confinement
Select stabilisation products using their interaction with the specified aggregate and the manufacturer’s validated design approach.
Project-Specific Design
Assess any change to aggregate thickness through a project-specific design comparison; savings are not a fixed percentage for every site.
Performance Over Soft Subgrades
Ground conditions, drainage, traffic and construction method are considered together before a stabilisation system is selected.
Documented Specification
Match reinforcement and paving interlayers to the approved design and maintenance objectives, with product-specific documentation.
Long-Term Design Strength
For structural reinforcement, use the specified long-term design strength and applicable reductions for creep, installation damage and durability.

| Specifications for Installing Geogrids & Interlayers
Before work starts — Confirm the product and grade against the approved drawings and manufacturer’s installation guidance. Record delivery identification and inspect rolls for damage. Accept the formation and agree the layout, reinforcement direction, overlaps or connections, fill specification and inspection hold points.
Placement — Lay the selected product in the design orientation without folds or damage. Use the project-specified overlaps and connections; stabilisation-grid laps are not a universal connection detail for structural wall reinforcement. Keep construction traffic off exposed material and check placement before covering.
Covering and QA/QC — Place and compact approved fill using the lift thickness and plant restrictions specified for the system and ground conditions. For asphalt interlayers, inspect the existing pavement, surface preparation, tack coat and placement before overlay. Record product identification, inspections, repairs and agreed test results for handover.
