Aperture interlock with the fill.
A geogrid is a polymer mesh with apertures sized so that fill particles partially pass through the mesh and lock into the aperture geometry. Unlike a geotextile (continuous fabric with primary load transfer along the yarn direction), a geogrid develops capacity through interlock between the rib structure and the surrounding granular material. This makes geogrids the preferred reinforcement when the fill is coarse and angular, and gives them a different load-transfer mechanism from woven geotextiles even when both products carry similar nominal tensile loads.
Two geometries dominate practice. Uniaxial geogrid has high tensile strength in one direction (machine direction, MD) and lower strength across, used where the design load is one-directional (a wall pulling horizontally on the reinforcement). Biaxial geogrid has equal tensile strength in MD and cross-machine direction (CMD), used where confinement under bidirectional loading is the design driver (under-pavement reinforcement, working platforms over soft ground).
Uniaxial PET and biaxial PP.
StrataGrid Uniaxial (PET)
High-tenacity polyester (PET) yarns drawn into a high-stiffness aperture grid, coated with PVC for dimensional stability. One-directional tensile capacity. Use: vertical MSE walls, segmental block walls, reinforced soil slopes, steep embankments, bridge abutments. Grades 30, 50, 80, 120, 160, 200, 300, 400 kN/m wide-width. Roll widths typically 1.0-1.3 m, lengths 50-100 m. Coloured selvedge identifies grade in the field. PET is the polymer of choice for tensile reinforcement because of its low creep behaviour.
StrataGrid Biaxial (PP / SGB)
Punched-and-drawn polypropylene (PP) sheet with square or rectangular apertures. Bidirectional tensile plus aperture interlock with aggregate. Use: paved road sub-base reinforcement on weak subgrade (reduces required aggregate thickness 20-50 percent), unpaved haul road stabilization, basal reinforcement under embankments on soft soil where lateral confinement is the failure mode. Aperture stability modulus (ASTM D6244) is a key performance metric alongside tensile.
STRATA also produces specialised reinforcement products under its wider portfolio including welded steel grids for very high-load applications and integral biaxial variants. Availability is confirmed against project demand. For tertiary or niche reinforcement, the right product is selected after consulting design and supply requirements.
Six core applications.
MSE walls / RE walls
StrataGrid uniaxial PET tied back into compacted reinforced fill, faced by precast concrete panels (StrataWall), modular blocks (StrataBlock), or other facing system. The geogrid carries the lateral earth pressure that the wall facing transmits. Federal highway, rail, port, hillside development applications. Practical heights 1-25 m+. Designed to BS 8006, FHWA-NHI-10-024, AASHTO LRFD.
Reinforced soil slopes (RSS)
StrataGrid uniaxial PET layered into compacted fill at 30°-70° face angle. Vegetatable face (StrataSlope wrap or geocell facing). Cheaper than vertical wall per m² of face when right-of-way allows the wider base. Highway widening, hillside platforms, landfill closure, dam crest reshaping. Designed to BS 8006, FHWA-NHI-10-024.
Basal reinforcement on soft ground
High-strength biaxial geogrid (or biaxial combined with woven HSR geotextile, see geotextile) laid horizontally below an embankment fill on soft clay or peat. Spreads load, prevents bearing-capacity failure and lateral spread. Port reclamation, ECRL/highway approaches over alluvial deposits, plantation drainage embankments on peat.
Paved roads and aircraft pavements
StrataGrid Biaxial under road sub-base or asphalt course. Reduces required aggregate thickness on weak subgrade (typical CBR less than 3 percent) by 20-50 percent. Extends pavement design life through aperture confinement of base aggregate. Plantation access, mining haul, parking platforms, container terminal aprons.
Steep embankments and cut platforms
StrataGrid uniaxial layered into engineered fill on hillside platforms (where excavation cost dominates and vertical face is required). Common on Klang Valley hillside developments and federal road widenings where land cost makes vertical face economical.
Bridge abutments (Shored MSE)
Hybrid: soil nail (or sheet pile) at the upper cut plus StrataGrid-reinforced fill below. The trestle or bridge deck founds on the reinforced fill. Used where right-of-way constraints prevent a conventional MSE approach embankment. Designed to FHWA-NHI-14-007 and BS 8006.
PET or PP.
| Property | Polyester (PET) | Polypropylene (PP) |
|---|---|---|
| Tensile strength / modulus | High, low elongation | Moderate, higher elongation |
| Creep at design load | Lowest, ~15-30% reduction over 100 years | Higher, ~25-40% reduction over 100 years |
| pH range for stability | pH 4-10 (avoid strong alkali contact zones) | pH 1-13 (broad) |
| Hydrolysis resistance | Susceptible at high temperature plus high pH | Excellent |
| UV resistance | Moderate (carbon black additive) | Moderate (UV stabiliser) |
| Typical use | Uniaxial high-strength reinforcement (MSE, RSS) | Biaxial confinement (pavement, working platform) |
Engineering shorthand: PET for load, PP for confinement. Both are stable across normal Malaysian residual-soil chemistry. Where the design requires both high tensile and good confinement (e.g. basal mat on soft ground), engineers often layer PET woven geotextile (or PET uniaxial geogrid) for tensile with biaxial geogrid for aggregate interlock above.
From design tensile to product selection.
Compute design tensile demand
For MSE walls and reinforced soil slopes, design tensile demand T_d at each reinforcement layer follows the limit-state framework in BS 8006 (Annex A) or FHWA-NHI-10-024. Internal stability checks (rupture, pullout, connection) and external stability checks (sliding, overturning, bearing, global slip) are performed at the design service life. The result is a required T_d per reinforcement layer.
Apply reduction factors
Convert manufacturer ultimate wide-width tensile T_ult to design tensile T_d using four reduction factors per ISO 13431 / BS 8006:
| Reduction factor | Typical range (PET) | Typical range (PP biaxial) | What it covers |
|---|---|---|---|
| RF_ID (installation damage) | 1.05-1.30 | 1.10-1.50 | Mechanical damage during fill placement |
| RF_CR (creep, 100 yr) | 1.40-1.80 | 1.80-2.20 | Time-dependent strain at sustained load |
| RF_CH (chemical, biological) | 1.00-1.20 | 1.00-1.15 | Higher in aggressive ground |
| RF_W (joins, junction) | 1.10-1.30 | 1.10-1.20 | Junction efficiency or seam loss |
T_d = T_ult / (RF_ID × RF_CR × RF_CH × RF_W). Total RF for PET uniaxial is typically 1.8-2.6, meaning a 200 kN/m T_ult product delivers 75-110 kN/m T_d depending on conditions.
Verify pullout and connection
Geogrid pullout capacity is governed by soil-grid friction coefficient and confining stress. ASTM D6706 (geogrid pullout test) provides values for design. Wall connection capacity depends on the facing system (panel, modular block, wire baskets), with manufacturer-specific connection strengths from STRATA datasheets.
Worked product selection example
For a 6 m MSE wall on residual soil with granular reinforced fill, with design tensile demand T_d of 28 kN/m at the highest stressed layer (per BS 8006 internal stability), applying total RF of 2.2 (PET, well-graded fill, neutral ground, panel facing) gives T_ult required = 62 kN/m wide-width. The next standard grade above 62 kN/m is StrataGrid 80 kN/m. Select 80 kN/m for the lower layers; transition to 50 kN/m for the upper layers where T_d demand is lower. Specific grade selection must be verified against the consulting engineer's design.
What changes in our climate and soils.
- Residual soil reinforced fill: Malaysian residual soil typically meets BS 8006 fill criteria after screening for plasticity and grading. Coarser hill-fill sources offer better aggregate interlock and lower RF_ID. Verify with grading curve and Atterberg limits.
- Marine clay basal: bridging soft marine clay (su below 15 kPa) with biaxial geogrid plus a layer of woven HSR geotextile combined system is common practice. Geogrid provides confinement, geotextile carries the tensile.
- Peat embankments: Sabah and Sarawak interior projects on peat require basal reinforcement design under Rowe-Soderman (lateral spread mode); biaxial geogrid + HSR woven geotextile combination is the working spec.
- Monsoon installation window: exposed geogrid (UV degradation) should be covered by fill or temporary protection within the manufacturer-stated window (typically 30 days for stabilised PET or PP).
- Tropical temperatures and PET hydrolysis: elevated soil temperature plus saturated saline conditions (coastal reclamation, port) can shorten PET design life if not specified properly. Use STRATA's published reduction factors for tropical service or specify hydrolysis-resistant grades for coastal applications.
- Authority spec: JKR-SPJ Section 7 governs slope and earthwork specifications for federal works. Local authority specifications layer additional requirements; MBPP Penang Hill Slope Guideline, DBKL hill land controls, MBPJ, MBSA, MBSJ, MPSJ, MPS each have specific submission practice.

Field practice that protects the design intent.
- Prepare subgrade or fill platform: remove sharp objects, trim to profile, compact previous lift to design density.
- Orient correctly: roll-out with machine direction aligned to design tensile axis (typically perpendicular to the wall face for MSE walls, along the embankment axis for some basal mats per design).
- Overlap or join: typical overlap 0.3-0.5 m for uniaxial PET (aperture interlock takes load across the joint); for higher-confidence applications, mechanical connectors or bodkin joins. Biaxial: 0.3 m overlap typical for pavement subgrade applications.
- Anchor at wall connection: for MSE walls, geogrid is connected to the wall facing via manufacturer-specific connection detail (cast-in tabs on panels, friction connection at modular blocks). Verify connection strength against design.
- First-lift fill placement: end-dump from one direction, push out with tracked dozer working from already-placed fill onto the geogrid. No tracked plant turning on bare geogrid. Lift thickness 200-300 mm minimum.
- Compaction: roller patterns per fill spec. Avoid heavy vibration directly above isolated geogrid points until covered.
- Document: roll-out log (roll number, batch number, position, orientation, overlap), photo of connection detail, post-placement survey of geogrid position before fill.
- Cover within UV window: default 30 days for UV-stabilised products. Confirm per datasheet.
One contact for material and installation.
Procurement under the STRATA Malaysia appointment runs through Starwall Sdn Bhd (supply, manufacturer certificates, logistics, technical liaison with STRATA Geosystems) and Infraconcrete Construction Sdn Bhd (CIDB G7, ISO 9001:2015, in-house installation crews, design support to the consultant). For the project owner this is a single-point procurement with one accountability chain for both the material and the workmanship.
For projects that prefer supply-only (installation tendered separately) or installation-only (material procured by main contractor under a separate package), both routes are workable. Tell us the procurement model at brief stage and we will respond accordingly.
