Soil remediation is the treatment, removal or containment of contaminated ground so that a site can be developed safely and to the standards required by regulators. SGE delivers soil remediation, land remediation and contaminated land remediation across brownfield, former industrial and infrastructure sites throughout the UK, working from the agreed remediation strategy through to validation. We bring earthworks, stabilisation and remediation capability together under one contractor, which removes the handover risk that exists when these are split across different firms.
Most of the sites we work on have a history. Former petrol stations, gas works, foundries, manufacturing plants, industrial estates and landfill-edge sites all turn up in our workload. Each comes with its own contaminant profile, its own regulatory expectations and its own commercial pressure to get the development started. The right remediation contractor is the one who understands all three dimensions and can deliver against them without surprises.
Detailed Service Breakdown
Every remediation scheme is shaped by the contaminant profile, the proposed end use and the planning conditions attached to the site. We deliver a range of treatment methods and select the right combination for each project. On a typical contaminated site we will excavate, segregate and classify material, treat what can be reused, dispose of what cannot, and validate the result so that the site can be signed off for development.
Soil remediation methods we deliver:
- Excavation, segregation and offsite disposal of contaminated soil
- Soil washing and screening for hydrocarbon and metals-impacted material
- Bioremediation for organic contaminants
- In-situ and ex-situ stabilisation and solidification
- Capping layers and clean cover systems
- Hotspot removal followed by validation sampling
- Asbestos-impacted soil handling under appropriate controls
- Contaminated water management and treatment
Where remediation is delivered alongside bulk earthworks and stabilisation, the same materials handling logic applies across the whole scheme. This reduces double-handling, lowers lorry movements and gives the client a single party accountable for the platform delivered to the next trade.
Industries and Sectors We Work With
Soil remediation work spans every sector that touches brownfield or contaminated land. Residential developers redeveloping former industrial sites are a major part of our workload, particularly on regeneration schemes where housing replaces previous commercial or industrial use. Commercial and logistics developers procure remediation on sites where the previous use left contamination that has to be cleared before building consent. Infrastructure clients, including highway and rail authorities, require remediation where existing corridors pass through legacy contamination. Public sector clients, including local authorities and regeneration agencies, commission remediation as part of wider land assembly and disposal.
Each sector has its own commercial drivers and procurement routes, and we adapt the approach accordingly. What stays constant is the quality of the validation work, because the regulator sign-off is the same whoever holds the contract.
Our Process and Delivery Method
1. Strategy review
We assist with reviewing the site investigation, remediation strategy and any planning conditions and inform the environmental consultant and client team.
2. Method statement and risk assessment
Detailed method statements cover containment, dust and odour control, materials tracking, validation sampling regime and waste classification. CL:AIRE and Definition of Waste Code of Practice routes are used where reuse is appropriate.
3. Mobilisation and site set-up
Site compounds are configured with the right separation, decontamination and welfare arrangements for the contamination present. Stockpile areas are segregated by classification.
4. Treatment and disposal
Material is treated, reused or disposed of according to the strategy. All movements are logged with waste transfer or duty of care documentation as appropriate.
5. Validation and reporting
Validation sampling confirms the remediation criteria have been met. A clear validation report is produced for the regulator and client.
Project Examples
Recent soil remediation projects include former industrial sites prepared for residential and commercial development, brownfield regeneration sites, and infrastructure schemes where hotspot contamination required hand-back to clean standards. We work routinely alongside environmental consultants and main contractors on schemes of all sizes.
Typical scopes have ranged from targeted hotspot removal on otherwise straightforward sites through to multi-phase remediation programmes combining excavation, treatment, stabilisation and capping across an entire former industrial estate. Validation packs have been delivered to local authority and Environment Agency satisfaction, supporting client sign-off and disposal of plots for development. Where soil remediation runs alongside bulk earthworks and stabilisation under the same contract, total project duration is typically shorter than running them as separate workstreams, because materials movement and platform delivery are planned as a single logical sequence.
Benefits of Working With SGE

- CL:AIRE and Definition of Waste Code of Practice procedures used routinely
- Self-delivery with owned plant and directly employed operators
- Strong programme certainty on time-sensitive brownfield schemes
Frequently Asked Questions
What is contaminated land remediation?
Contaminated land remediation is the process of treating, removing or containing contamination in soil or groundwater so a site can be safely used for its intended purpose. The approach is driven by the contaminant type, concentration and the end use of the site.
Do I need a remediation strategy before work starts?
Yes. Remediation works are normally carried out against a remediation strategy agreed with the local authority and regulator. We work to the strategy provided by the environmental consultant rather than producing it ourselves.
Can contaminated soil be reused on site?
Often yes, subject to treatment and to the controls set out under the CL:AIRE Definition of Waste Code of Practice. Reuse reduces disposal cost and lorry movements significantly.
Do you handle asbestos-impacted soils?
Yes, under the appropriate licensing, controls and method statements. Asbestos-impacted soil is treated as a specialist subset of remediation work.
