Service

Gajawari KW executes high-volume bulk earthworks for mining, civil, and infrastructure projects across Western Australia.

Material is moved, placed, and compacted to spec, with full control over geometry, density, and sequencing across large footprints and varying ground conditions.

Scope & Execution

We move large material volumes across zones to establish working levels and balance site elevations. Haul routes, load cycles, and fill sequences are optimised to minimise rehandling. Equipment is matched to volume, distance, and material type for efficient throughput.

We rework stockpiled, spread, or in-situ material to meet design grades and surface tolerances. Regrading operations address slope adjustments, level corrections, or alignment refinements. Surface finish and compaction are validated through survey and test results.

We construct embankments and form batters with controlled lifts and slope geometry. Placement is managed to achieve design stability and erosion resistance. Edge transitions, tie-ins, and drainage interfaces are shaped to integrate with adjacent structures or terrain.

We prepare the final working layer below pavements or structural foundations by trimming, conditioning, and compacting material to required strength and moisture levels. Verification includes density testing and proof rolling to confirm load-bearing capacity.

We manage the movement, placement, or disposal of spoil generated from cut operations. Haulage routes are staged to reduce double handling and interaction with other site traffic. Reusable material is stockpiled to specification, and unsuitable spoil is segregated for off-site disposal or containment.
