Cut and fill contractor in Malaysia.
Infraconcrete Construction Sdn Bhd is a specialist cut and fill earthworks contractor across Malaysia. CIDB Grade G7 (highest contractor grade), ISO 9001:2015 certified. We cut from high ground, mass-haul internally, place engineered fill in controlled lifts, and compact to design density (95 percent MDD general fill, 98 percent MDD structural backfill) to form ready-to-build platforms. Delivered earthworks scope including Bandar Serendah (540,000 m3 backfill) and Eco Terraces Phase 2 Semenyih (120,000 m3 earthworks). Field density verified by nuclear density gauge, sand-replacement and DCP. Per BS 6031, BS 1377, JKR-SPJ Section 2 and MS 1227.
The cut and fill workflow, end to end.
Site clearing and topsoil strip
Clearing, grubbing and stripping of topsoil and unsuitable surface material, stockpiled for later landscaping reuse. Setting out to the survey grid, establishing benchmarks and the ESCP before bulk works. Strip and stockpile at 5,000 to 10,000 m2 per shift.
Bulk cut and excavation
Cutting from high ground to design formation with tracked excavators and dozers. Cut material is classified at source: suitable soil routed to fill, unsuitable (soft, organic, high-plasticity) separated out. Bulk cut in residual soil runs 2,000 to 4,000 m3 per shift.
Mass haul and cut-fill balance
Internal haul roads and a mass-haul plan move cut to fill along the shortest economic route. Cut-fill balance is measured against platform design so surplus disposal or imported fill is quantified before works start, not discovered on the final measure.
Engineered fill placement
Fill spread in controlled loose lifts of 200 to 300 mm, moisture-conditioned near optimum, and compacted with the right plant for the soil (smooth-drum vibratory for granular, padfoot for cohesive). Placement and compaction at 1,500 to 3,000 m3 per shift per crew.
Compaction to design density
Every layer compacted to the specified MDD (95 percent general fill, 98 percent structural backfill) and density-tested before the layer above is placed. Nuclear density gauge, sand-replacement and DCP per BS 1377 and MS 1227, logged and signed off per lift.
Subgrade prep and platform formation
Final trim and grading to design levels and falls, proof-rolling, and subgrade preparation to CBR where specified. Handover of a level, drained, ready-to-build platform with as-built survey and compaction records. Subgrade trim at 3,000 to 6,000 m2 per shift.
How a platform is built up.
| Stage | Activity | Control |
|---|---|---|
| 1. Set out and strip | Survey control, clear and grub, strip topsoil to stockpile, install ESCP | Setting-out check, silt traps and cut-off drains in place before bulk works |
| 2. Bulk cut | Excavate high ground to formation, classify material at source | Suitable vs unsuitable separation, batter angles to temporary cut design |
| 3. Mass haul | Move cut to fill on internal haul roads per mass-haul plan | Haul-road maintenance, cut-fill balance tracked against design |
| 4. Foundation prep | Prepare and proof-roll the fill foundation, remove soft spots, bench into slopes | Proof-roll observation, benching on steeper ground per BS 6031 |
| 5. Fill in lifts | Place fill in 200 to 300 mm loose lifts, condition moisture, compact | Lift thickness check, moisture near optimum, roller passes recorded |
| 6. Density test | Test each compacted layer for field dry density | 95 percent MDD general, 98 percent MDD structural, engineer sign-off per layer |
| 7. Trim and form | Final trim to levels and falls, subgrade preparation, proof-roll | Level survey, CBR where specified, platform handover records |
Unsuitable material is never placed as structural fill. Where the cut is deficient or the platform sits on soft ground, the works tie into ground improvement and retaining walls to hold the design levels.
What moves the earth.
| Plant | Role on a cut and fill site |
|---|---|
| 50-tonne excavator | Primary bulk cut, loading dump trucks, deep excavation to formation |
| 20-tonne excavator | Secondary cut, trimming, benching, trench and drainage works |
| Articulated dump truck (ADT), 30 and 50 tonne | Mass haul of cut to fill on internal haul roads, surplus cart-away |
| Bulldozer | Spreading fill, pushing and levelling lifts, haul-road formation |
| Motor grader | Fine trimming to levels and falls, subgrade and formation finishing |
| Smooth-drum vibratory roller (12 to 22 tonne) | Compaction of granular and mixed fill, subgrade proof-rolling |
| Padfoot (sheepsfoot) roller | Compaction of cohesive clay fill, kneading action on plastic soils |
| Pneumatic-tyre (PTR) roller | Sealing and finishing compaction, surface knitting on subgrade |
| Vibratory plate compactor | Compaction in confined zones, behind structures, around services |
| Hydraulic breaker | Breaking hard ground and boulders on excavator refusal in weathered rock |
Plant is matched to soil type and lift. See the construction equipment and machinery guide for how excavator, haul and compaction plant are selected and sized against production targets.
Indicative output on residual soil.
| Operation | Plant combination | Rate per shift |
|---|---|---|
| Topsoil strip and stockpile | Excavator + dozer + ADT | 5,000 to 10,000 m2 |
| Bulk cut, residual soil | 50-tonne excavator + 30-tonne ADT | 2,000 to 4,000 m3 |
| Bulk fill placement and compaction | Dozer + roller crew, 200 to 300 mm lifts | 1,500 to 3,000 m3 per crew |
| Subgrade preparation and final trim | Grader + roller | 3,000 to 6,000 m2 |
Rates are for typical Malaysian residual soil and drop on hard-ground refusal, wet weather, long internal haul, or restricted working hours. Multi-crew mobilisation lifts total output on large or time-critical platforms. Full cost and duration modelling in the cost and programme guide.
How we prove the fill is engineered.
| Item | Target / method |
|---|---|
| General fill | Compact to 95 percent Maximum Dry Density (MDD) |
| Structural backfill and subgrade | Compact to 98 percent MDD (or stricter per specification) |
| Lift thickness | 200 to 300 mm loose, adjusted to soil and roller |
| Moisture control | Placed and compacted near optimum moisture content from Proctor |
| Laboratory reference | Proctor compaction test for MDD and optimum moisture (BS 1377 / MS 1227) |
| Field density | Nuclear density gauge (fast in-situ), sand-replacement (reference method) |
| Subgrade strength | DCP (Dynamic Cone Penetrometer) and CBR where specified |
| Records | Per-layer test log by level and grid, engineer sign-off before next lift, ISO 9001:2015 traceable |
No layer is buried until its density test passes. This is what separates engineered fill that carries a building platform from uncontrolled tipping that settles and cracks slabs later.

What actually moves the earthworks programme.
- Monsoon and rain days. Wet cohesive fill will not reach MDD. Placement stops above the workable moisture window and saturated formation is dried back or removed. Northeast monsoon (roughly November to March, heaviest on the east coast) is planned around, with rain float built into the programme.
- Cut-fill imbalance. A cut-heavy site needs surplus disposal, a fill-heavy site needs imported fill. Both change cost and duration, so the mass-haul balance is quantified up front rather than discovered on the final measure.
- Hard-ground refusal. Weathered rock and boulder horizons slow the cut and drop excavator output. Hydraulic breaking or ripping is planned where the soil report and probing flag refusal, so the programme is not blindsided at formation level.
- ESCP and drainage. The Erosion and Sediment Control Plan (silt traps, cut-off drains, sediment basins) must stay live for DOE and JPS compliance. Exposed platforms are sealed and cambered for runoff, which protects the compacted works and keeps the site open through wet spells.
Local-authority coordination is routine on our sites: we hold project experience with bodies such as DBKL, MBPJ, MBSA, MPSJ, MPS, state JKR, DOE and JPS, and align earthworks to their ESCP and drainage requirements.
