Leading Geosynthetics supplier in Malaysia.

Polymer products engineered for civil engineering functions.

A geosynthetic is a polymer product manufactured to perform a defined function inside the ground or between soil and another material. ISO 10318 (the umbrella terminology standard) categorises geosynthetics by their primary function: reinforcement, filtration, separation, drainage, protection, containment, or surface erosion control. The polymer choice (PET, PP, HDPE, LLDPE, PVC, EPDM) and the product form (mesh, fabric, cellular, sheet, composite) follow from the function, not the other way around.

For Malaysian projects, geosynthetics replace, augment, or extend conventional soil and rock solutions in ways that often deliver lower lifecycle cost, faster construction, more sustainable resource use, and design flexibility for site-specific constraints. A reinforced soil slope using geogrid is typically cheaper and quicker than a tall RC retaining wall. A geomembrane-lined pond is impermeable in a way no clay liner can match. A geocomposite drainage layer takes 10 percent of the space of a gravel chimney drain. A geocell vegetated slope facing solves erosion on a steep cut where pure hydroseeding would wash away. The point of the geosynthetics category is to give engineers a wider toolbox.

This hub page connects to the dedicated product pages for each category, the design guides for engineers, the specification guides for QSs and spec writers, and the scenario-specific guides for MSE walls, reinforced soil slopes, landfill liners, road base reinforcement, drainage, and slope facing.

Function-led selection.

Five steps from project to product.

1. Declare the function. Reinforcement (tensile, holding a wall back or a slope from spreading). Filtration (water flow through, fines held back). Separation (two soils kept from mixing). Drainage (water flow in-plane, away from the area). Protection (cushion against puncture). Confinement (lateral restraint of fill within cells). Containment (impermeable barrier against fluid).
2. Pick the category. Reinforcement = geogrid (or woven geotextile for high tensile basal mats). Filtration / separation / drainage / protection = geotextile (nonwoven mostly). Confinement = geocell. Containment = geomembrane. Combined drainage = geocomposite.
3. Pick the polymer. PET for primary tensile reinforcement (lowest creep, 100+ year design). PP for filtration and confinement and short-term reinforcement (broad chemistry, lower cost). HDPE for containment and 3D confinement (chemical durability). LLDPE for flexible containment over irregular subgrade. PVC for water-only containment. EPDM for specialty.
4. Size to design demand. Reinforcement: design tensile per BS 8006 / FHWA-NHI-10-024, then apply reduction factors per ISO 13431. Filtration: AOS / permittivity / gradient ratio per FHWA-NHI-07-092. Confinement: cell depth and width per FHWA-NHI-15-067 and load distribution. Containment: thickness per GRI-GM13 / GM17 and DOE Malaysia or sector regulator.
5. Verify installation survivability and durability. Reduction factors (RF_ID, RF_CR, RF_CH, RF_W) convert ultimate to long-term design strength. Manufacturer datasheets carry declared values. Project-specific spec defines QA frequency and acceptance.

Each step is covered in detail in the dedicated design guides (linked below).

The four working polymers and where each fits.

What changes in our climate and soils.

• Residual soil with high fines: filter design tightens retention (smaller AOS). Reinforcement design adjusts soil-grid friction for the actual fill source. Gradient-ratio testing recommended for critical filters in residual soil with 30+ percent fines.
• Marine clay and peat at the coast: basal reinforcement demand is high (Rowe-Soderman lateral spread mode dominates). Basal mats and biaxial geogrid combined system is standard. PVDs alongside for consolidation.
• Monsoon installation window: exposed geosynthetics (UV degradation) cover within 30-day window for stabilised PET and PP, shorter for PVC. Plan critical works in dry-window forecast.
• Tropical temperature plus saturation: HDPE and PP buried in stable soil chemistry are well-behaved. PET in coastal saline plus elevated temperature plus alkaline contact requires project-specific durability check (hydrolysis). PVC plasticiser migration accelerated in heat.
• Acidic peat porewater (Sabah, Sarawak): verify chemical reduction factor for any geosynthetic specified in deep peat with porewater pH below 4.
• Authority spec: JKR Cawangan, MBPP Penang Hill Slope Guideline, DBKL hill land controls, DOE Malaysia (waste containment). Each has its own submission practice; consulting engineer coordinates project-specific.
• Federal infrastructure references: Malaysian federal expressway, rail, port, and runway projects routinely use geosynthetics in basal reinforcement, MSE walls, drainage, and containment scopes.

What to cite in your design report.

One contact for the whole geosynthetics scope.

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). Three workable models:

1. Single-point (recommended): Starwall supplies + Infraconcrete installs. One contact for both material and workmanship; one accountability chain.
2. Supply-only: material through Starwall, installation tendered separately. Used when the project has a preferred installation contractor or when scope splits make sense.
3. Installation-only: Infraconcrete installs material procured through any STRATA distributor (Starwall is the Malaysian distributor). Used when main contractor packages supply differently.

Tell us the procurement model at brief stage and we will respond accordingly. STRATA datasheets and certificates of conformance are available on request for spec writing in any model.

Cost bands for budgeting.

Numbers are indicative for orientation; actual pricing depends on grade, lead time, quantity, project access, programme, current STRATA list prices, and FX. Tender for project-specific delivery.
