Innovative remediation for a sustainable future.
We specialise in the treatment of contaminated soils and groundwater, playing a vital role to ensure your site is safe and ready for future development. Sirius holds a mobile treatment licence, which permits us to apply a range of cutting-edge remediation technologies. Our goal is to treat contaminated materials on-site, reducing the need for off-site disposal and minimising environmental impact, whilst meeting all regulatory requirements.
Expert soil and groundwater remediation.
The UK’s long industrial history has left behind a legacy of brownfield land requiring remediation. Sirius has extensive experience in providing solutions for sites with a contaminative past, such as former gasworks, steel manufacture, and chemical production. Sirius has successfully delivered hundreds of projects where soil and groundwater treatment has been a critical component of remedial earthworks. A key benefit of our approach is the ability to safely retain contaminated soils on-site, lowering costs for our clients while supporting environmental sustainability.
Hazardous materials
Solidification and stabilisation soil treatment.
Our innovative Soil Treatment and Recycling (STAR) process enables Sirius to treat heavily contaminated soils using binders that stabilise and lock in harmful substances, allowing the soil to be reused on-site. We employ specialised equipment, such as the Mobile Soil Recycler (MSR), which accurately doses and mixes binders into contaminated soils. This process ensures the safe reuse of materials, reducing waste and costs associated with off-site disposal. Sirius’ expertise also includes the treatment of hazardous asbestos in soils, utilising asbestos qualified operatives to safely inspect, monitor and manage asbestos on site.
Advanced treatment technologies
State of the art equipment and processes.
The treatment of groundwater is another crucial aspect of our remediation projects. We deploy both traditional and advanced techniques including Pump and Treat systems or in-situ methods such as oxidant and substrate injection to dissolve and degrade hydrocarbon contaminants such as total petroleum hydrocarbons (TPH), poly-aromatic hydrocarbons (PAH), and chlorinated solvents.


Expertise and efficiency in remediation
Experienced teams; exceptional results.
Sirius success is driven by the expertise of our experienced site teams, who ensure maximum productivity and efficiency in the field. Our technical staff have a deep understanding of ground conditions, conceptual site models, and risk assessments, allowing us to deliver remediation strategies that meet client objectives while staying within budget. With a strong track record in managing complex soil and groundwater treatment projects, Sirius is the trusted partner for ensuring contaminated sites are fully remediated and ready for safe development. Our integrated approach combines technical excellence with practical site management, providing a seamless, cost-effective service.

Sirius specialises in brownfield remediation, reusing on-site materials where possible to avoid expensive landfill disposal. We apply specialist remediation technologies to reduce contamination and disposal volume.
Geotechnically suitable soils may also require stabilisation to resolve contamination issues. Sirius conducts detailed sampling and trials to create cost-effective remediation strategies, reducing the need for disposal or import of material.
Sirius is committed to innovation, sustainability, and delivering exceptional results.
