Geotextile installer in Malaysia.
Infraconcrete Construction Sdn Bhd is the field-execution specialist for geotextile installation across Malaysia. CIDB G7 crew with seam welding capability (sewn and thermal), anchoring, overlap audit, and on-site QA per BS 8006 / JKR-SPJ Section 7. Daily install rates 800 to 3000 m squared per crew depending on application complexity. Multi-crew mobilisation for tight programmes. Coverage across all 13 states plus Labuan, with same-day site response in Klang Valley.
Who turns up on a typical site.
| 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 |
Standard crew runs 4 to 8 personnel. Multi-crew mobilisation runs 2 or 3 parallel crews under shared site engineering for sites over 50,000 m squared single deployment or tight-programme jobs.
Overlap, sewn, thermal.
Overlap seam
300 to 500 mm minimum lap, no stitching. Used for separation and filtration applications where the geotextile is not structurally responsible. Fastest install rate, lowest cost. Acceptable for nonwoven separation under roads, working platforms, drainage trench wrap.
Sewn seam
Prayer stitch, J seam, or butterfly stitch using portable industrial sewing machines (Newlong DKN-2BP, DS-9C-A or equivalent). Polyester or aramid thread. Used for structural reinforcement: basal reinforcement, reinforced soil walls, RSS, geotextile-encased columns. Tested seam strength typically 60 to 90 percent of fabric tensile strength.
Thermal seam (welded)
Hot-wedge or hot-air welding. Used for impervious-membrane applications where the seam needs to match the membrane's water barrier. Less common on geotextile (geotextile is mainly used for permeable applications); used where the geotextile is the bonding layer to an HDPE liner or where chemical compatibility prevents stitching.
How the geotextile locks to the ground.
| Application | Anchoring detail |
|---|---|
| Slope-face wrap | U-pins or J-pins (6 to 10 mm bar, 300 to 600 mm long) at 1 to 2 m grid |
| Slope-crest trench | 600 to 1000 mm deep trench, geotextile wrapped down into trench, backfilled with granular soil and compacted |
| Slope-toe anchor | Trench anchor or pin anchoring depending on toe configuration |
| Basal reinforcement (at embankment edge) | Friction lock between fill layers, no separate anchorage typically required |
| Reinforced soil wall layers | Friction lock between compacted fill layers, no separate anchorage |
| Drainage trench wrap | Overlap closure at top of trench, pinned where required at panel boundaries |
| Rip-rap or gabion mattress underlay | Trench anchor at upstream and downstream extents to prevent flanking failure |
What gets built in a working day.
| Scope | Day rate per crew |
|---|---|
| Nonwoven separation layer, flat subgrade, overlap only | 1500 to 3000 m² per day |
| Woven PET basal reinforcement, sewn seam | 800 to 1500 m² per day |
| Slope-face wrap with anchoring (1V:1.5H to 1V:1H) | 400 to 800 m² per day |
| Drainage trench wrap (linear) | 100 to 200 m per day per trench |
| Rip-rap or gabion mattress underlay | 600 to 1200 m² per day |
| Reinforced soil wall reinforcement layers | 500 to 1000 m² per day per layer |
Rates assume normal access, daylight working, dry weather. Wet weather, restricted access, or night shift reduces rates 20 to 40 percent. Multi-crew mobilisation scales linearly within the practical site footprint.
What the crew brings on site.
| Equipment | Use |
|---|---|
| Roll-handling spreader bar | Telehandler or excavator attachment for unrolling 4 to 5 m wide rolls |
| Portable industrial sewing machine (Newlong DKN-2BP, DS-9C-A) | Field seaming for woven PET reinforcement |
| Hot-wedge seam welder (where required) | Thermal seaming for impervious membrane scope |
| Pin anchoring tool set | U-pins, J-pins, trench anchor steel |
| Measuring wheel + offset gauges | Layout marking, overlap measurement audit |
| Sample-cutting kit | Batch sampling for retention, fresh-cut on-site CBR specimens |
| Digital camera + tablet | Photo log, daily diary, as-built markup, real-time upload |
| PPE + slope-work harness | Mandatory for steep-face installations |
| Traffic management kit | Cones, signage, barriers for work near live carriageway |
How we work at height and on slopes.
Slope-work harness mandatory for any installation on slopes steeper than 1V:1.5H or above 3 m height. Anchor points pre-installed at crest before crew descends. Two-rope system (working line + backup line) per installer. Buddy system: minimum 2 installers per slope sector, never solo work. Daily toolbox talk including weather check (suspend in heavy rain or lightning). Site safety walk by site engineer before crew descent. All crew CIDB Green Card holders. Slope-work safety records submitted as part of the handover documentation.
For live highway or rail corridor installations, traffic management coordination with the Highway Authority or rail operator, staged closures, lane management, night-shift mobilisation. Concrete barrier and hoarding deployment for crew protection. Authority-approved traffic management plan submitted before mobilisation.
Crews mobilised across all 13 states.
- Klang Valley (Selangor, KL, Putrajaya, Cyberjaya): same-day site response, daily crew availability.
- Penang, Kedah, Perlis: 1 to 2 day mobilisation.
- Perak, Negeri Sembilan, Melaka, Johor: 1 to 2 day mobilisation.
- Pahang, Kelantan, Terengganu: 2 to 3 day mobilisation, East-coast monsoon-period scheduling.
- Sabah, Sarawak, Labuan: project-specific mobilisation 3 to 7 days.
Site managers and supervisors usually ask:
Can you install material we've already procured? +
How quickly can a crew mobilise for an emergency? +
What if seam testing fails on production samples? +
Do you work weekends or night shift? +
Can you install in monsoon conditions? +
Do you supervise other subcontractors' geotextile install? +
