Geosynthetics · Geocell · STRATA Sole Distributor

Geocell supplier & installer in Malaysia.

Our group sister company Starwall Sdn Bhd (same ownership as Infraconcrete) is the sole appointed Malaysia distributor of STRATA Geosystems. StrataWeb is a 3D honeycomb panel of UV-stabilised black HDPE strips, ultrasonically welded together. When opened on site and filled with granular material, vegetated topsoil, or concrete, confined fill behaves stiffer than free fill, bearing capacity rises 2-3×, lateral spread is suppressed, and surface erosion drops to near-zero. Cell depths 75 / 100 / 150 / 200 mm. Perforated and non-perforated. To ASTM D7864, ISO 13426, NCMA, FHWA-NHI-15-067. CIDB G7. ISO 9001:2015.

01 / How geocell works

Confine the fill, borrow its stiffness.

Granular fill on its own resists vertical load by friction and minimal cohesion. Under cyclic traffic or rainfall the grains migrate, the surface ravels, and bearing capacity drops. Confining the same fill inside a honeycomb of welded HDPE strips changes the mechanics: each cell wall provides hoop tension that resists outward spread, and the welded seams provide interlock between cells. Confined fill is now a composite layer, measurably stiffer (typically 2-3× modulus) than the same fill without confinement.

This confinement effect is the basis for all four StrataWeb application families: slope protection, channel lining, load support on weak subgrade, and retaining-wall infill. Same product, four applications, design varies by cell depth and fill type.

02 / Four applications

Where StrataWeb fits.

Vegetated slope protection

Cell depth 75-100 mm. Open cells filled with topsoil + Vetiver / local grass species. Holds soil on slopes 1V:1.5H to 1V:0.7H through Malaysian monsoon. Perforated walls let vegetation roots interlock between cells. Common on highway and rail cut slopes, hillside developments.

Concrete-filled channel lining

Cell depth 100-150 mm. Cells filled with C25-C30 concrete become an articulated channel lining, flexes with differential settlement, no joints to leak. Replaces cast-in-situ concrete channel. High-velocity (>5 m/s) monsoon discharge channels, spillways, drainage outfalls.

Load support on weak subgrade

Cell depth 100-200 mm. Aggregate-filled cells over a separation geotextile reduce aggregate thickness 30-50% vs unconfined. CBR equivalence, 300 mm geocell-confined ≈ 600 mm conventional on soft clay. Mining haul, plantation access, lay-down yards, parking platforms.

Retaining wall & gravity wall

Stacked geocell layers, soil-filled, become a gravity retaining wall. Vegetatable face. Lower-cost alternative to gabion in 1-4 m height range. Combined with StrataGrid for taller walls. Architectural finish, green slope, no exposed steel.

05 / Installation method

How StrataWeb goes in.

01

Subgrade preparation

Strip topsoil, grade to design profile, place separation geotextile (nonwoven 200-300 g/m²) on weak subgrade. Subgrade compaction to 95% MDD where applicable.

02

Anchor & open the panel

Pin top of slope or top edge of installation with steel J-pins or proprietary anchors. Open the welded panel, cells expand to design dimensions. Verify cell shape via diagonal measurement.

03

Tendon connection (slopes)

For steep slopes, connect adjacent panels via woven polyester tendons through factory-formed slots. Anchor tendons to top-of-slope deadman trench or rock bolts. Establishes panel-to-panel continuity.

04

Fill the cells

Place fill from the lowest point upward (slope) or from one end (channel). Avoid dropping fill from height, risks bursting cell walls. Compact lightly via hand or vibratory plate. Top off cells flush with cell walls.

05

Vegetation / surface treatment

For vegetated applications: hydroseed Vetiver / local grass mix. Cover with coir mat for first monsoon. Inspect after first 3 months; reseed bare cells. For concrete fill: cure 7-14 days, no traffic until C25 strength reached.

06 / Reference contexts

Where StrataWeb is at home.

Highway cut slopes

EKVE alignment slopes. Vegetated geocell on cut faces above engineered shotcrete + soil nail. Long-term green appearance, low maintenance.

Hillside developments

Klang Valley + Penang hill projects. StrataWeb retaining walls (1-4 m) for terraced platforms in residential and commercial schemes.

Mining & plantation

Quarry haul roads (Selangor, Pahang, Perak limestone). Plantation access roads (Sabah, Sarawak). Aggregate-confined load support replaces deeper conventional sub-base.

Channel & spillway

Monsoon discharge channels. Concrete-filled cells deliver flexible articulated lining, no construction joints, fast install. Common on industrial estates and highway drainage outfalls.
