PRODUCT DATA. DESIGN CONTEXT.
Dimensions, material properties and practical information for engineers and specifiers. Use the current product certificate alongside the project specification.
| Parameter | Value / description |
|---|---|
| Mesh opening | 50 × 50 mm |
| Roll width | 2.95 m |
| Roll length | 100 m |
| Nominal roll area | 295 m² |
| Tensile strength | ≥92 kN/m |
| Reinforcement | Basalt fibre |
| Coating | Alkali-resistant coating |
| Form | Flexible mesh geogrid |
The ≥92 kN/m tensile rating was confirmed by BasaltechSA in September 2026. Request the current product test certificate for test method, direction and design values. Net installed coverage depends on overlaps and cutting.
| Property | Specification | Reported test result |
|---|---|---|
| Fibre length | 24 ± 1 mm | 23.8 mm |
| Fibre diameter | 16 ± 1 µm | 16.6 µm |
| Breaking strength | ≥1,000 MPa | 1,420 MPa |
| Elongation at break | 2 to 3% | 2.4% |
| Strength retention | ≥85% | 90% |
| Density | ≥2.6 g/cm³ | 2.63 g/cm³ |
| Moisture content | ≤0.20% | 0.05% |
| Oil absorption | ≤6.00% | 4.96% |
Coating: X-SBR (styrene-butadiene). Custom lengths are available on request. Strength-retention test conditions are not stated in the flyer; request the laboratory report to assess suitability for the intended exposure.

03 / DESIGN CONTEXT
SPECIFY THE SYSTEM,
AS WELL AS THE GRID.
The 92 kN/m product rating is not a pavement design capacity. The design also depends on the grid’s interaction with adjacent materials, bond, loading, environment and construction sequence.
- Confirm tensile method, test direction and characteristic values.
- Obtain coating and durability data for the actual exposure.
- Specify grid position, fixing, laps and bonding requirements.
- Check construction tolerances and the acceptance test programme.
04 / MIX DESIGN INPUTS
CHOPPED FIBRE.
MIX GUIDANCE.
| Application | Guideline dosage |
|---|---|
| Residential concrete floors | 1.5 to 2.5 kg/m³ |
| Industrial floors | 2.5 to 4.0 kg/m³ |
| Warehouse slabs | 3.0 to 5.0 kg/m³ |
| Concrete pavements | 3.0 to 6.0 kg/m³ |
| Thin concrete roads | 4.0 to 6.0 kg/m³ |
| Precast elements | 2.0 to 4.0 kg/m³ |
| Asphalt mixes | 3 to 5 kg per tonne of asphalt |
These are the flyer’s detailed table values. Its combined industrial and warehouse summary gives a broader range; use the separate application rows above. Final dosage is subject to mix design and the engineer’s specification. Confirm through project-specific mix trials.
05 / MATERIAL TAKE-OFF
ESTIMATE YOUR QUANTITIES.
Calculate nominal mesh roll requirements or fibre mass from your own area, mix quantity and dosage inputs.
Nominal roll area: 2.95 m × 100 m = 295 m². Enter the allowance for your laying plan. The default 10% is a budgeting assumption.
ESTIMATED ROLL REQUIREMENT4rolls
1 100 m² including allowance. Rounded up to whole rolls.
Request a quotation ↗Quantity estimate only. Does not calculate structural capacity, pavement thickness, reinforcement equivalence or a suitable fibre dosage.
06 / SUPPORTING INFORMATION
DATA FOR THE
PROJECT FILE.
Request the applicable product certificate, test methods, durability information and installation or mixing guidance from BasaltechSA.
PRODUCT DISTINCTION
Product pamphlets & source notes ↗Mesh, chopped fibre and rigid BFRP bars are different material forms. Standards, test results and structural design provisions should not be transferred between them without a justified assessment.
