Professional site rehabilitation contractors in WA. Servicing metro and regional areas including Perth, Karratha, the Pilbara and the South West.
Gajawari KW restores disturbed ground following construction, mining, and access works across Western Australia.
Rehabilitation is executed to environmental and landholder requirements, with material reconditioning, reshaping, and reestablishment of stable ground profiles.
We reshape disturbed or unstable landforms to match design contours and meet drainage and stability requirements. Cut and fill volumes are balanced across the site to reduce double handling and achieve consistent compaction. Our use of machine control systems ensures accuracy in slope angles, berm construction, and final grading, reducing the risk of erosion and future failure.
Topsoil is stripped, stockpiled, and redistributed under controlled conditions to preserve structure and nutrient profile. Placement is managed to specified depths with uniform spread and minimal compaction, supporting vegetation establishment and reducing surface runoff. We coordinate timing with surface prep and planting schedules to maintain biological viability.
We install temporary and permanent drainage to stabilise regraded land and control surface water. This includes contour banks, diversion drains, and rock-lined flow paths. Systems are engineered to direct runoff without concentrating flows that cause scouring or slope destabilisation. Structures are sized to handle site-specific flow rates and rainfall variability.
We prepare surfaces through decompaction, cross-ripping, and moisture conditioning to promote seed take and root penetration. Surface treatments are matched to seed mix requirements and terrain type. Prep works are sequenced to avoid rainfall-induced erosion and to align with rehabilitation milestones.
We implement erosion controls using check banks, sediment fences, jute matting, and temporary diversion structures. These are deployed in advance of significant earth disturbance and maintained until vegetation is established. All controls are designed to meet site-specific slope, soil, and flow conditions and are integrated with drainage design.
