Contaminated Soil and Remediation Support

Some demolition and excavation sites uncover contaminated soil, asbestos fragments, old fill, fuel/oil impacts or unexpected waste. Direct Demolition can assist with excavation, loading, site clearing and disposal coordination where appropriate specialists/reports are involved.

What We Can Assist With

Excavation and loading of impacted soil
Site clearing and separation of waste streams
Working with environmental consultants/project managers
Truck access and spoil removal planning
Clean-up after demolition or excavation

Important

Contaminated material must be classified, handled and disposed of correctly. Reports, consultant direction and approved disposal pathways may be required before works proceed.

Send Before Pricing

Send any contamination report, asbestos report, soil classification, site photos, access notes and required disposal/handover requirements.

Contaminated Soil & Remediation — Deeper Detail

Contaminated soil work in Sydney usually arises from old service stations, light industrial sites, ex-orchards (organochlorines), legacy fuel tanks, or sites with bonded asbestos in soil. The job is two parts: classification and disposal.

Classification Categories (NSW EPA)

General Solid Waste (GSW): standard clean fill alternative — lowest tip cost
Restricted Solid Waste (RSW): mid-tier, requires lined landfill
Hazardous Waste: highest tip cost, limited tip choice, often pre-sorted
Asbestos in Soil: separate handling and disposal stream

Cost Drivers

Volume (m³ in-bank) — biggest single number on the quote
Classification — RSW typically 2–3× GSW; Hazardous 4–6×
Tip location — Sydney metro RSW tips charge $150–$300/t
Trucking — distance to the nearest accepting tip
Hand-pick vs mechanical excavation where asbestos in soil exists

Typical Workflow

Phase 1/2 contamination report from your environmental consultant
Lab analysis classifies the soil per EPA guidelines
We mobilise excavator, dump trucks and dispatcher
Excavate, segregate, stockpile per class, sample if required
Validation sampling once the dig is complete
Tip dockets, environmental sign-off and clearance pack handed to your consultant

Asbestos in Soil

If bonded fragments are visible or suspected, the dig is staged: hand-pick of visible fragments first, then mechanical removal under a registered AHRA-style controlled excavation. We tarp stockpiles, wet down dust, decontaminate plant on exit and provide an air-monitoring program where required.
