Geotextile contractor in Malaysia.
Infraconcrete Construction Sdn Bhd is a CIDB G7 geotextile installation contractor across Malaysia. Site crew, supervision, on-site QA/QC, and as-built documentation for slope works, basal reinforcement on soft ground, drainage trench wrap, reinforced soil walls and slopes, retaining wall drainage, and rip-rap underlay. As the sole appointed STRATA Geosystems (Asia) distributor in Malaysia (through Starwall Sdn Bhd), we run supply + install under a single contract, single supplier, single warranty. ISO 9001:2015 quality management system. 23 client projects delivered 2022 to 2026 including EKVE, ECRL, Lingkaran Tengah Utama Kelantan.
Single-point responsibility, start to handover.
The buyer's incentive to engage a geotextile installation contractor over a supply-only route is risk transfer. The contractor takes responsibility for the geotextile actually working in service. Eight scope items typically wrap into the contract:
- Material receipt against mill certificate, batch sampling for retention, ground preparation acceptance with the consultant.
- Layout per consultant drawings, including overlap orientation, machine-direction alignment for woven reinforcement, and seam location planning to avoid weak-point coincidence with peak load.
- Anchoring at slope crest, toe, and at any panel terminations (pin anchoring for slope works, trench anchor for basal layers, U-pin staples for nonwoven).
- Seaming or overlap per consultant spec: sewn seam (prayer / J / butterfly stitch) for permanent reinforcement, overlap 300 to 500 mm for separation and filtration applications, thermal seam (welded) where the consultant has specified it.
- Protection during fill placement: no direct traffic on bare geotextile, controlled tip height (typical 0.5 m maximum first lift), aggregate gradation check (no oversize stones that could puncture).
- On-site QA per BS 8006 / JKR-SPJ / consultant spec: roll-by-roll inspection, overlap measurement audit, seam quality check, photo log, daily diary.
- Pull-out and CBR puncture testing on production samples where the spec calls for it (typically reinforced soil walls, basal reinforcement, geotextile-encased stone columns).
- As-built record: photo log, roll-batch traceability, daily diary, exception register, handover sign-off with the consultant.
Where the crew goes most often.
Slope works
Geotextile wrap on slope face, anchored at crest with trench and at toe with pinning. Nonwoven for filtration behind drainage works, woven PET for structural slope reinforcement. Pairs with soil nailing and guniting on cut slopes.
Basal reinforcement on soft ground
Woven PET (StrataTex HSR) at the base of an embankment over peat or soft marine clay. Sewn seam, oriented with machine direction across the failure surface. Pairs with PVD for accelerated consolidation. See also basal reinforcement.
Drainage trench wrap
Nonwoven PP wrap around perforated subsoil drains, French drains, chimney drains. Filter sock for fines retention. Linear scope, faster install rate.
Reinforced soil walls and slopes
Woven PET reinforcement layers spaced per design (typical 0.4 to 0.8 m vertical spacing). Compaction control critical for design-strength delivery. See MSE wall and RSS.
Retaining wall drainage
Nonwoven PP separating drainage gravel from retained soil behind RC cantilever, MSE, modular block, or gabion walls. Pairs with geocomposite wall drain.
Rip-rap and gabion mattress underlay
Nonwoven PP between rock armour or gabion mattress and underlying soil. Prevents wave or flow action from washing fines out from under the armour. Common on river training and coastal protection. See gabion wall.
Who turns up on a typical site.
A standard geotextile installation crew runs 4 to 8 personnel depending on scope and programme pressure:
| Role | Responsibility |
|---|---|
| Site engineer (1) | Engineer-in-charge, consultant liaison, daily diary, exception decisions |
| Site supervisor (1) | Crew foreman, daily progress, safety briefing, toolbox talks |
| Senior installer (1 to 2) | Layout, overlap and orientation control, seam quality |
| Installation crew (2 to 4) | Roll deployment, seam sewing or overlap placement, anchoring, pinning |
| Plant operator (as needed) | Telehandler or excavator for roll handling, aggregate spreading on top of geotextile |
For larger sites (over 50,000 m squared single deployment), multi-crew mobilisation runs 2 or 3 parallel crews under shared site engineering. For tight-programme projects (federal corridor with traffic management), night-shift mobilisation possible.
What the consultant sees at audit.
The standard QA record handed over with each panel set:
- Roll receipt log: roll number, batch number, mill certificate cross-reference, visual inspection record.
- Sample retention: cut from each batch, retained for the project duration plus the warranty period.
- Ground preparation acceptance: photo log of subgrade prior to geotextile placement, signed off by site engineer and (where applicable) consultant.
- Layout drawing markup: as-installed orientation, overlap dimensions, panel boundaries, anchorage points.
- Seam log (where seam is specified): seam type, stitch count, operator identification, daily seam quality check.
- Overlap audit: random sample measurement of overlap width across the installation area.
- Protection log: aggregate tip height, machine traffic restrictions, lift thickness during fill placement.
- Pull-out / CBR puncture test reports (where spec requires).
- Daily diary + photo log covering all of the above.
- Handover sign-off with the consultant signing acceptance of the as-built condition.
What the crew brings on site.
| Equipment | Purpose |
|---|---|
| Roll-handling spreader bar | Telehandler or excavator attachment for unrolling large rolls (typical 4 to 5 m wide) |
| Portable sewing machine (Newlong / equivalent) | Field seaming for woven PET reinforcement, prayer / J / butterfly stitch |
| Hot-wedge seam welder (where specified) | Thermal seaming for impervious membrane scope or specialist nonwoven welded seam |
| Pin anchoring tool set | U-pins, J-pins, trench anchor steel for slope-face wrap |
| Measuring wheel + offset gauges | Layout marking, overlap measurement audit |
| Sample-cutting kit | Batch sampling for retention, fresh-cut specimens for on-site CBR if spec calls |
| Digital camera + tablet | Photo log, daily diary, as-built markup, real-time upload to project record |
| PPE + traffic management kit | Hard hat, hi-vis, safety boots, slope-work harness, cones, signage |

Consultants and main contractors usually ask:
Do you take design responsibility or just install? +
What does CIDB G7 actually mean for my project? +
Can you do install only (no material supply)? +
How fast can a crew mobilise for an urgent slope failure? +
What insurance do you carry? +
Do you do safety briefings and toolbox talks? +
