A Coal Mining Risk Assessment (CMRA) evaluates the potential ground stability hazards associated with historic coal mining activity. Many parts of the UK contain shallow mine workings, abandoned shafts, and geological weaknesses that can impact construction and planning approval.
At Phase Ground Investigation, we deliver professional Land Contamination Assessments to support planning applications, property transactions, and development projects across the UK. Our experienced team provides clear, reliable, planning-compliant assessments for residential, commercial, and industrial sites.

A Phase 1 Desk Study, or Preliminary Risk Assessment (PRA), is the first essential step in understanding a site’s potential environmental and geotechnical constraints. At Phase Ground Investigation, we specialise in delivering high-quality, planning-compliant reports that provide a clear picture of any potential risks before development proceeds.

Reliable ground information is essential before any construction, planning or development work begins. At Phase Ground Investigations, we provide clear, accurate and cost-effective ground investigation services designed to assess soil, rock and groundwater conditions across residential, commercial and industrial sites.
Radon is a naturally occurring radioactive gas present in varying concentrations across the UK. While harmless outdoors, it can accumulate indoors or within confined ground conditions, presenting a significant health risk if not properly assessed.
Rotary drilling is a core technique used to investigate deep or dense subsurface conditions as part of Geotechnical and Geo-Environmental ground investigations.

Understanding the shallow ground conditions beneath a site is essential for safe and cost-effective construction. At Phase Ground Investigations, we provide professional trial pit excavation services designed to give a clear visual assessment of sub-surface conditions.
Window Sampling — also known as Dynamic Sampling, Mini Boreholes, or Windowless Sampling — is a versatile site investigation technique used for geotechnical and environmental assessment.
Professional ground and site investigations are essential to understand the soil, rock and groundwater conditions beneath a site. Our investigations support foundation design, reduce construction risk and help avoid costly surprises during development.
We use proven techniques including window sampling, trial pits, boreholes and laboratory testing to gather accurate subsurface data and deliver clear, actionable reports.
All our services are backed by clear, planning-ready reporting and ongoing technical support. We explain findings in plain English and remain available to assist with planning queries, design coordination and follow-up requirements.
