Ground Investigation & Geotechnical Expertise Across the Welsh Landscape

Specialist Geo-Environmental Expertise for Cardiff & The Valleys 

Development in Wales is often a journey through its industrial past. The South Wales Coalfield, stretching from the Valleys down to the coast, leaves a legacy of shallow workings and historic mine shafts that demand mandatory, high-level Coal Mining Risk Assessments. Our Cardiff-based team has spent years mapping these risks, providing the technical certainty needed to build safely on historic ground. 

From the urban regeneration of Cardiff Bay to rural infrastructure in West Wales, we balance engineering rigour with a deep respect for the Welsh environment. 

Key areas of expertise include: 

• Trial Pits: A vital, cost-effective first step for profiling the varied glacial soils of the Valleys and inspecting historic foundations in Cardiff’s urban core. 
• Rotary Drilling: The essential tool for probing the deep rock strata of the Coalfield, identifying voids and ensuring ground stability in former mining communities. 
• Soil Sampling: Comprehensive chemical and geotechnical analysis to manage the industrial “Made Ground” found throughout the M4 corridor and Newport’s industrial zones. 
• Window Sampling: Small-footprint, high-efficiency drilling perfect for the restricted access of Cardiff city centre developments and tight valley sites. 
• Cable Percussion Boreholes: The industry standard for deep investigation into the soft alluvial clays of the Welsh coastline and Cardiff Bay’s regenerated docklands. 

We regularly support projects across Cardiff, Swansea, Newport, Bridgend, and the Valleys, where regional geology and Welsh planning nuances require a specialist local partner.
