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.

| Hand-held auger / Klemm 802-3 mini | 50-100 mm / 3-6 m | Tight urban sites, restricted access, shallow nails |
Drilling method by ground
- Rotary (top hammer): standard for soil + weathered rock, fast in Grade III-VI
- Down-the-hole (DTH) hammer: for hard rock (Grade I-II granite), straighter holes
- Rotary-percussive: hybrid, common for mixed-face conditions
- Sacrificial casing (water flush) drilling: for cohesionless soil to prevent hole collapse
- Cable percussion (shell + chisel): traditional, used in soft soil + investigation
Productivity benchmarks
- Soil nail (32 mm GEWI, 12 m, residual soil): 4-8 nails / day per rig
- Rock bolt (25 mm threadbar, 6 m, weathered rock): 6-12 bolts / day per rig
- Ground anchor (4-strand, 25 m, mixed face): 1-3 anchors / day per rig
- Micropile (200 mm dia, 20 m): 1-2 piles / day per rig
02 / Micropile & Pile Rigs
For underpinning, ground improvement, and foundation works.
| Rig type | Pile dia / depth | Use |
|---|---|---|
| Klemm KR 909 / Casagrande M9-M16 | 150-300 mm / 20-40 m micropile | Underpinning, micropile, anchored wall foundations |

03 / Grout Plants
Where the bond strength is made.
Plant components
- Cement silo / bagged storage: typically 30-50 ton silo on large projects, bagged for small
- Water tank with flow meter: chilled water for hot-day hydration control
- Colloidal mixer (high-shear): Atlas Copco LMV 50/100, IMT MAGICAL, Casagrande Maxima - 200-500 L drum, 1500-3000 rpm impeller. Produces stable, low-bleed grout

- Mud balance: daily / per-batch density check (target 1.85-1.95 g/cm^3)
- Bleed test apparatus, cube moulds: 7-day + 28-day QA
Grout mix QA
- OPC w/c 0.40-0.45 (target by design)

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 |
|---|---|---|---|
| Wet-mix shotcrete | Concrete batcher / transit mixer + concrete pump (Putzmeister BSA 1005 D, Aliva 252, Sika-PM 500/700) + nozzle + air supply (compressor 8-12 bar, 6-10 m^3/min) | 6-12 m^3/hour | Large slope facing, tunnel primary lining, bulk volume work |
| Dry-mix shotcrete (gunite) | Aliva 246 / Putzmeister DSP / Reed dry-mix machine + pre-blended dry materials + water at nozzle | 1-3 m^3/hour | Small / repair work, remote sites, vertical narrow strips |

| Mobile elevating work platform (MEWP) - boom lift / scissor lift | any (level-ground access) | Mid-height inspection, finishing | 2-person, 250 kg |
| Cable-supported platform | any (very tall / cliff-face) | Specialist - rope access teams, drilled anchors | 1-2 person specialist crew |
| Track-mounted spider rig (self-platform) | any (rough terrain) | Klemm KR 805-3 G2 self-traverses without separate scaffold | n/a (rig is the platform) |
Slope-platform mapping. Selection driver is slope angle, total face height, drilling depth, equipment weight, and access. For a 30 m vertical-to-near-vertical permanent slope (typical hillside development cut): suspended scaffold for upper half, system scaffold for lower bench. For a 60-degree 15 m slope: tube-and-coupler scaffold or system scaffold. For a 45-degree gentle slope: track-mounted spider rig directly on the cut face. Working at height + working from suspended platforms requires DOSH (Department of Occupational Safety and Health) certified scaffolders, signed off scaffold inspection records, fall arrest harnesses + lanyards.

Frequently asked
Equipment questions.
What drilling rig for soil nailing? +
Anchor / micropile rig with rotary or rotary-percussive head: Klemm KR 805-3 / 806-3 / 807-3 / 909, Atlas Copco Christensen, Soilmec SM series, Casagrande C5/M9, Comacchio MC450/600, IMT A series. Hole 100-150 mm dia, 6-15 m length, 10-20 deg below horizontal. Track-mounted for accessible terrain, scaffold-mounted for steep / inaccessible.
What's the typical shotcrete equipment? +
Wet-mix (preferred): batcher / transit mixer + Putzmeister BSA 1005 / Aliva 252 / Sika-PM pump + nozzle + 8-12 bar compressor. Dry-mix (gunite): Aliva 246 / Putzmeister DSP + 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 (Hydro Mobile, Saferise) for sustained vertical work on tall walls. Tube-and-coupler / system scaffold for slopes up to 60 deg. Track-mounted spider rig (Klemm KR 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 (Atlas Copco LMV, IMT MAGICAL, Casagrande Maxima) + piston pump (Atlas Copco SmartPump, IMT IM3000) + 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.
