This page is a working reference for engineers, developers, QSs and contractors covering StrataTex HSR high-strength woven polyester (PET) for basal reinforcement, plus needle-punched nonwoven polypropylene (PP) for separation, filtration, drainage, protection, and erosion control. Local Selangor stock for common grades, ex-factory for heavy and specialised grades, nationwide delivery across all 13 Malaysian states. Filter criteria, AOS / permittivity / permeability, polymer selection, tropical Malaysian residual-soil + marine-clay + peat context. Designed to BS 8006, ASTM D4595 / D4751 / D4491 / D4533 / D5261 / D5101, ISO 10319 / 11058 / 12956 / 13431, AASHTO M288, FHWA-NHI-07-092, JKR-SPJ. ISO 9001:2015.
One material, five functions.
A geotextile is a permeable polymer fabric placed inside the ground, between two soil masses, or between soil and another material. It is one of the oldest and most widely used geosynthetics. Geotextiles do not do magic; they perform one or more of five well-defined civil engineering functions, and selection is a function-led decision before it becomes a polymer-led or brand-led decision.
Reinforcement
The geotextile carries tensile load (a woven fabric resists pulling along the machine direction). Used in basal mats under embankments, reinforced fill behind walls, paved-road sub-base, steep slope facing systems. Designed to BS 8006 / FHWA-NHI-10-024.
Separation
Two soils with different gradings are prevented from mixing. Classic case is sub-base aggregate above weak subgrade: without separation, fines pump up into the aggregate under traffic and the road dies. AASHTO M288 separation class.
Filtration
Water flows through (cross-plane) but fines stay back. The standard wrap around a perforated drain pipe, behind a retaining wall back-drain, between gabion mattress and natural ground, under riprap on a riverbed. Sized by AOS + permittivity per FHWA-NHI-07-092.
Drainage
Water flows along the plane of the fabric (in-plane transmissivity). Thick needle-punched nonwoven, or a geocomposite (nonwoven faces plus a 3D drainage core like StrataDrain) takes the role. Common behind walls, in landfill caps, below pavements.
Protection
The geotextile is a cushion between an underlying liner (geomembrane) and a potentially puncturing aggregate or surface above. Mass per unit area drives puncture resistance. Mandatory above HDPE liners in landfill basal liner systems, often above pond liners.
Erosion control
Surface or buried fabric protects soil from raindrop impact, sheet flow, or wave action while vegetation establishes. Coir mats and turf reinforcement mats are surface variants; nonwoven geotextile is the underlay below dumped riprap on streambeds and bridge piers.
One fabric may serve more than one function (a nonwoven wrap on a French drain is both separation and filtration). The dominant function should drive the spec; the secondary function is verified after.
Woven HSR and needle-punched nonwoven.
StrataTex HSR (woven PET)
Yarns of high-tenacity polyester woven in a regular weave. Engineered as reinforcement. Tensile load is carried along the machine direction (and at lower magnitude across-machine). Grades 20-1000 kN/m wide-width. Roll widths typically 4.5-5.3 m, lengths 100-200 m. Coloured selvedge identifies grade in the field. Not a filter, the open area of a woven HSR is far too small for high permittivity but the geometry is not designed to retain fines either.
Nonwoven (needle-punched PP)
Random short fibres mechanically interlocked by needle punching. Engineered as filter, separator, drain, cushion. The 3D random fibre structure produces a controllable AOS combined with high in-plane and cross-plane water flow. Sized by mass per unit area (100, 150, 200, 300, 400, 600, 800 g/m²) and verified by AOS (typically 0.06-0.25 mm), permittivity (typically 0.5-3.0 s⁻¹), and grab tensile / puncture for installation survivability.
STRATA also produces additional fabric types under the wider STRATA Geosystems portfolio for niche applications (woven-monofilament for separation under heavy traffic, slit-film for utility wraps, specialist coated products). Availability is confirmed against project need.

The rule of thumb engineers use day-to-day: PET for load, PP for water. Both can be specified to last decades when applied in their right function. Mixing them up (e.g., asking a low-strength PP fabric to take primary tensile in an MSE wall) is the most common source of failure when comparing materials only on cost per m².
The three rules that decide AOS.
A geotextile filter must pass three tests in series. Failing any one of them turns the filter into either a blockage, a leak, or a slow clog. The criteria below are from FHWA-NHI-07-092 and BS 8006, with adjustments for Malaysian residual soils that often carry a high fines content.
Retention
The fabric must hold back the protected soil. Express as a relationship between O95 (apparent opening size, ASTM D4751) and the soil grading. Stable cohesionless soils: O95 below D85 of the soil. Internally unstable soils, or soils with a gap-graded curve: O95 should drop further, sometimes to D50 of the soil. Dispersive clays: full-piping test or chemical stabilisation may be needed before the geotextile alone is considered safe.
Permeability
The fabric must let water through faster than the protected soil, otherwise hydraulic head builds up across the filter and accelerates piping. Express as permittivity ψ of the geotextile (ASTM D4491) against permeability k of the soil. A common starting rule: ψ × t_fabric (effective k of the geotextile) at least 10 times k_soil. For Malaysian residual soils where k_soil is in the 10⁻⁶ to 10⁻⁸ m/s range, almost any properly chosen nonwoven satisfies this; on coarse sands or gravels it can be the binding constraint.
Anti-clogging
The fabric must remain open enough through its design life that flow stays adequate. Verified by gradient-ratio testing (ASTM D5101) on a soil-geotextile sandwich. Gradient ratio below 3 is conventionally acceptable. Long-term flow capacity (LFTL) testing is the higher-confidence variant where the soil is known to be problematic (high fines, dispersive, marine origin).
For Malaysian residual soil with 20-40 percent fines, typical filter specification: nonwoven PP 200-300 gsm, AOS 0.10-0.20 mm, permittivity above 1.0 s⁻¹, gradient ratio under 3. Specific spec must be verified against actual borehole grading curves.
Where geotextile fits.
Basal reinforcement on soft ground
StrataTex HSR woven, laid horizontally on the prepared subgrade before the embankment fill is placed. The fill produces a lateral spreading force at the base; the woven fabric carries that horizontal tensile, prevents bearing capacity failure and mud-wave, and limits lateral deformation. Design follows BS 8006 (slip-circle plus tensile capacity check) or Rowe-Soderman for very soft conditions (peat, marine alluvium with shear strength below 10 kPa). Malaysian sites: port reclamation (Port Klang, Penang Port, Kuantan Port), highway and rail approach embankments over alluvial deposits (ECRL, KESAS approach), plantation drainage embankments on peat (Sabah and Sarawak interior).
Separation under road sub-base and aggregate platforms
Nonwoven PP 200-400 gsm placed between the weak subgrade and the granular sub-base. Prevents fines from pumping up under repeated wheel loading, prevents aggregate from being lost to the subgrade, preserves the drainage path designed into the pavement section. Standard on plantation access roads, oil-and-gas yard platforms, container terminal aprons, mining haul roads. AASHTO M288 Class 1, 2 or 3 selection depends on subgrade CBR and design traffic.
Filter wrap on subsurface drainage
Nonwoven PP 150-300 gsm wrapped around perforated uPVC or HDPE drain pipe in a French drain, behind a retaining wall toe drain, around a horizontal drain outlet collector. Lets water flow into the pipe while holding back fines from the surrounding soil. Sized by the three filter criteria (retention, permeability, anti-clogging) against the actual soil grading.
Cushion above geomembrane
Nonwoven PP 400-800 gsm laid above an HDPE or LLDPE geomembrane in a landfill basal liner, landfill cap, or pond liner. Protects the geomembrane from puncture by overlying drainage aggregate, recovery wells, or vehicle traffic during construction. Required by GRI-GT12 and most DOE / regulator specifications. Mass per unit area drives puncture resistance; 600 gsm is a common minimum for stone leachate collection layers.
Reinforced fill behind retaining walls
Either StrataTex HSR woven as primary reinforcement (lower-cost alternative to geogrid in some configurations) or nonwoven as secondary reinforcement at the wall connection / drainage zone. Behind RE / MSE walls, modular block walls (e.g. StrataBlock), and reinforced soil slopes. Where the design demands geogrid (aperture interlock with coarse fill), the woven fabric is replaced by geogrid; where the design demands a fabric filter behind the facing, nonwoven is added.
Erosion control underlay below riprap
Nonwoven PP 200-400 gsm laid on the prepared subgrade, then dumped riprap is placed on top. The fabric prevents soil washout under wave action or stream flow while letting water pass. Edge anchoring (return into a buried trench, soil staples) is critical so flow under storm conditions does not roll up the fabric. Bridge piers, river training, channel lining, breakwater toe; combine with FHWA-HEC-23 design for permanent works.
What changes in our climate and soils.
Tropical residual soil with high fines
Many Malaysian sites sit on weathered residual soil with a high fines content (silt and clay greater than 30-40 percent) and a stable open structure when undisturbed. Disturbed fines mobilise easily during construction. Filter spec needs to push retention harder than tabulated international averages: nonwoven AOS at the lower end of the catalogue (0.10-0.15 mm) is a safer default than letting AOS drift up to 0.25 mm to chase a permittivity number.
Marine clay and peat at the coast
Coastal alluvium and peat (West coast, East coast, Sarawak interior) have undrained shear strength as low as 5-15 kPa near the surface. Basal mat tensile demand can exceed 200 kN/m to control mud-wave and lateral spread under a 4-6 m fill height. Use Rowe-Soderman for very soft ground rather than a slip-circle plus tensile factor on its own. Plan vertical drains (PVDs) alongside the basal mat for consolidation; the fabric is a construction-stage reinforcement, not a substitute for consolidation.
Monsoon installation window
Peninsular Malaysia north-east monsoon (November to March) and south-west monsoon (May to September) bring high-intensity rainfall events. Exposed geotextile (UV degradation, mud-wash) should be covered by fill or aggregate within the supplier-stated installation window (typically 30 days for stabilised PET or PP; longer windows exist for specific UV-rated products). For projects with extended exposure (e.g. erosion control under riprap in a tidal zone), specify a UV-stabilised product and validate with manufacturer datasheet.
Authority spec and submission
JKR-SPJ Section 7 governs slope and earthwork specifications on federal works. Local authority specifications (MBPP Penang Hill Slope Guideline, DBKL hill land controls, MBPJ, MBSA, MBSJ, MPSJ, MPS) layer additional design and submission requirements on top. Geotextile specification typically references AASHTO M288 (separation, filtration classes) and ASTM properties for performance acceptance. Manufacturer certificates of conformance from STRATA accompany every consignment and form part of the QA submission.

Field practice that protects the design intent.
- Prepare subgrade. Trim to design profile. Remove sharp objects (roots, boulders, debris) that would puncture the fabric on first lift placement.
- Orient correctly. Lay the geotextile with the machine direction aligned with the design tensile load (basal mat: machine direction along the embankment axis or across, per design).
- Overlap or seam. Unsewn overlap typically 0.5-1.0 m. For tensioned applications (basal mats above 100 kN/m design), prayer-seam or J-seam stitching to manufacturer's published seam strength.
- Anchor edges. Returns into burial trenches, soil staples, or fold-and-stake details prevent pull-back under traffic and stop wind uplift before cover.
- First-lift fill placement. End-dump from one direction, push out with a tracked dozer working from already-placed fill onto the geotextile. Do not turn tracked plant on bare geotextile. Lift thickness 200-300 mm minimum on soft subgrades.
- Compaction. Use roller patterns compatible with the fill spec, not the geotextile. Avoid heavy vibration directly over isolated fabric points.
- Document. Roll-out log (roll number, batch number, position, overlap), photo record of overlap and anchor details, post-placement survey of fabric position before first lift.
- Cover within UV window. Default 30 days exposure for standard UV-stabilised products. Confirm against datasheet for specific grade.
