Sirius Geotechnical & Environmental Ltd

Sirius Geotechnical Ltd provides specialist ground-risk advice and drilling services from its base in Langley Moor, supporting development projects across the United Kingdom. Its work covers both brownfield and greenfield sites, with particular expertise in geotechnical investigation, environmental risk and the challenges associated with historical mining.

The geotechnical team undertakes desk studies, site investigations, coal-mining risk assessments, geo-environmental appraisals, geotechnical design, risk assessments, remediation strategies, material management plans and validation work. Phase 2 investigations can include drilling, sampling, groundwater testing and risk assessment, tailored to the needs of each site.

Its drilling operation provides rotary site investigation, open-hole probe drilling, core drilling and mineral investigations. Contract drilling includes water-well installation and GSHP loop installation, while geotechnical drilling covers rock anchors, soil nails and instrumentation. The company also delivers drilling and grouting for new developments, mine-entry treatment, bulk infill and specialist grouting.

Clients include residential, commercial, renewable-energy, waste and minerals-sector organisations, as well as developers seeking planning, regulatory or pre-acquisition support. With in-house links to earthworks, remediation, demolition and civil engineering teams, Sirius can combine investigation, design and practical ground solutions for complex sites. Its modern drilling fleet and integrated approach are particularly suited to projects where technical advice and site delivery need to work closely together.
