Why we own our plant
We don't sub the geotechnical work to chains of vendors - the drilling crew, the grout plant, the shotcrete team, and the supervisor are all Infraconcrete. That's why programmes hold and quality is consistent across the projects we've delivered. If your project needs same-day mobilisation in the Klang Valley or scheduled mobilisation across Malaysia, send the brief to WhatsApp +60 16-428-1214 for a same-day engineering response.

02 / Micropile & Pile Rigs
For underpinning, ground improvement, and foundation works.

Colloidal vs paddle mixer. Colloidal mixers produce stable, low-bleed grout suitable for permanent geotechnical works. Paddle mixers (drum mixers, low shear) produce unstable grout that bleeds and segregates - acceptable for temporary works but NOT for permanent anchors / nails per BS 8081 / EN 1537. Specify colloidal mixer in the contract spec.
04 / Shotcrete Machines
Wet-mix and dry-mix sprayed concrete.
| Method | Equipment | Output | Best for |

Dry-mix (gunite): dry-mix machine / dry-mix machine + dry pre-blend + water at nozzle. SFRS adds steel-fibre dosing. Output: wet-mix 6-12 m^3/hour, gunite 1-3 m^3/hour.
What staging platforms for steep slopes? +
Suspended scaffold (gondola) for vertical to overhanging - drilling, shotcrete capable. Mast climber (international mast-climber manufacturers) for sustained vertical work on tall walls. Tube-and-coupler / system scaffold for slopes up to 60 deg. Track-mounted spider rig (specialist anchor rig G2) self-traverses on rough terrain - no separate scaffold. Selection by slope angle + height + equipment weight + access.
How is grout plant set up? +
Cement silo / bagged storage + water tank + colloidal mixer (colloidal mixer, colloidal mixer, colloidal mixer) + piston pump (piston pump, piston pump) + hose lines + mud balance + cube mould + bleed test apparatus. Mix: OPC + w/c 0.40-0.45 + plasticiser 0.5-1 percent. Target 30-50 N/mm^2 cube. Density 1.85-1.95 g/cm^3. Bleed less than 2 percent. Pre-construction trial mix.
Why colloidal mixer instead of paddle mixer? +
Colloidal mixers (high-shear, 1500-3000 rpm) produce stable, low-bleed, segregation-resistant grout suitable for permanent works per BS 8081 / BS EN 1537. Paddle mixers (drum, low shear) produce unstable grout that bleeds and segregates - acceptable for temporary works only. Specify colloidal mixer in contract spec for permanent geotechnical works.
