Soil remediation and contaminated land clean up, Australia wide
Soil and environmental remediation: Contaminated soil out, clean validation in
- Excavation, staging, classification and disposal of contaminated soil to your consultant's RAP
- Asbestos in soil under our own Class A licence, from surface picking to bulk removal
- Bioremediation, on site treatment and reuse where it beats the gate rate
- Chain of custody on every load and the evidence trail your auditor needs
Perfect Contracting is the soil and environmental remediation arm of Perfect Group. We excavate, treat, cart and validate contaminated ground for developers, builders, government and industry, usually between the demolition and the construction, so the site your project needs is the site you get handed back.

Remediation is an evidence job as much as an earthmoving job
Anyone can dig contaminated dirt and cart it away. The value is in doing it so the site validates: excavating to the remediation action plan, keeping clean and dirty material separated, tracking every load to a licensed facility, and giving the auditor a paper trail with no holes in it. We work alongside your environmental consultant rather than around them. They classify and validate, we excavate, treat, manage and dispose, and the handover is a site that passes rather than a site that argues.
Soil remediation has been part of what we do since the company started in 2010, and it usually sits between our demolition and someone else's construction. One contractor across demolition, remediation and early works means no re-mobilisation, no argument about whose dust that was, and a programme that actually connects.
What we handle
Contaminated soil excavation and disposal
Excavation, staging, on site classification with your consultant and disposal to licensed facilities, with the dockets passed through. City by city: Sydney, Newcastle, Wollongong, Brisbane, Gold Coast and Sunshine Coast.
Asbestos in soil
Bonded and friable asbestos contaminated fill managed under the NSW EPA guidance and our own Class A licence, from surface picking to bulk excavation with air monitoring and independent clearance. See how asbestos contaminated soil is removed.
Hydrocarbons, PCBs and heavy metals
Fuel, oil and solvent impacted ground around old plant, workshops and service stations, PCB contamination from older electrical and industrial sites, and lead, arsenic and other metals. Classified, excavated and disposed of or treated.
Bioremediation and on site treatment
Hydrocarbon impacted soil turned and treated in windrows on site, screened and validated for reuse as fill, so it never pays a gate rate. See bioremediation of soil.
Underground storage tanks
Tanks pumped out, purged, gas tested and lifted out under an independent hygienist, the pit excavated, held open for validation, then backfilled and compacted. See underground tank removal.
Acid sulfate soil, groundwater and dewatering
Acid sulfate soil managed to the plan with liming and controlled stockpiling, and groundwater handled with dewatering and treatment where the excavation goes below the water table.
Keeping disposal costs sane
Disposal is the budget killer in remediation, and the difference between general solid waste and restricted waste rates is enormous. Careful staging, on site classification with your consultant, and not mixing clean with dirty routinely saves more than the excavation costs. We will also tell you when material can be treated or reused on site instead of carted, because the cheapest tonne is the one that never leaves. Where the contamination is under a slab or a structure, the remediation is priced with the industrial demolition so the two scopes do not fight each other.
Have a RAP already? Send it with the site investigation report. We price to the plan, and if we can see a cheaper compliant path we will say so before you commit. If you only have a preliminary site investigation, send that and we will tell you what the RAP is likely to ask for.
What a job like this looks like
Emu Plains, for Akura, is a fair example of a full remediation package. A former industrial parcel at 158 to 164 Old Bathurst Road had to become a clean, validated development platform inside an active precinct, with demolition and remediation each running under its own development consent and a remedial action plan, an unexpected finds protocol and a demolition traffic management plan sitting over the lot.
The demolition came first, sequenced so the heavy work did not spread contamination into ground that was already clean. Concrete from the structures was crushed on site, tested and validated for reuse, so it never went to a gate. Hydrocarbon impacted soil was treated by bacterial bioremediation rather than carted, then tested and validated for full clearance in line with the consultant's requirements. Everything that did have to leave went to appropriately licensed facilities with the dockets passed back. Six months, zero incidents, zero lost time injuries, and a platform the client could build on. The full write up is on the Emu Plains project page.
Remediation jobs we have done
Industrial ground: Emu Plains for Akura, described above; PCB contaminated soil at the old Austral Plant 3 at Horsley Park, found during demolition and mapped, removed and disposed of under strict controls; and the Cleanaway tank farm at Unanderra, where the slab and the ground under a liquid waste plant were remediated and validated after the tanks came out.
Asbestos in soil: Bonnyrigg Estate Stage 2 for JK Williams and Traders in Purple, friable and bonded asbestos in fill managed under the NSW EPA guidance, and The Gables for JK Williams, about twelve weeks from standing farm buildings to a validated subdivision platform, with the contaminated soil remediation run under a schedule of rates.
Tanks and fuel: five underground tanks at Medlow Bath for Arenco, pumped, purged, gas tested, lifted out and the ground beneath them excavated, validated and backfilled, and an underground fuel tank on a live infrastructure site at Lidcombe for Abergeldie.
Where we work
Head office and yard in Marrickville, Sydney, a Queensland yard in Slacks Creek, Brisbane, and contaminated land crews that travel nationally on staged programmes. Travel and float are priced up front. For a site moving into closure that needs the earthworks, contamination and demolition scope delivered against a rehabilitation plan, see mine closure and rehabilitation works.
Questions we get asked
Do you do the environmental consulting too?
No, and you would not want your contractor marking their own homework. We work to your consultant's remediation action plan and they classify and validate our work. If you do not have a consultant yet we can suggest ones we have worked with.
What about asbestos found in the soil?
Common on old industrial, rural and demolition sites. We handle it under our own asbestos licences, from hand picking bonded fragments off the surface through to bulk excavation of friable material under Class A controls, with clearance by an independent licensed assessor.
How do you charge for disposal?
At documented gate rates with the dockets passed through, plus cartage. You see what each classification cost, load by load. The difference between general solid waste and restricted waste rates is enormous, which is why staging and classification matter so much.
Can you treat the soil on site instead of carting it?
Sometimes, and we will tell you when. Hydrocarbon impacted soil can often be bioremediated in windrows on site, as it was at Emu Plains, and some material can be screened, tested and reused as fill. The cheapest tonne is the one that never leaves.
Can you just make the contamination go away cheaper?
No, and be careful of anyone who says yes. Illegal dumping lands on the landowner. What we can do is stage and classify carefully so you never pay restricted rates for clean material.
Is this Perfect Contracting or Perfect Remediation?
Perfect Contracting. Soil, contaminated land and environmental remediation sit with our demolition and civil crews because the work is excavation, classification and validation. Perfect Remediation handles the group's structural, concrete and surface remediation work and does not do soil.
