Geotechnical and Environmental Associates (GEA) is an independent specialist providing a high-quality ground investigation and geotechnical and geoenvironmental consultancy service to the property and construction industries. GEA’s team of experienced and highly qualified geotechnical and geoenvironmental engineers provides a complete service, from Phase 1 desk studies, through ground investigation, interpretive reporting, analysis and monitoring, to final validation where necessary.

We work for a range of clients, including multinational organisations, property developers, funding institutions, major retailers, educational establishments, local authorities, housebuilders, housing associations and private individuals. Our expertise is applicable to a wide range of projects, including investment acquisitions and divestures, new housing developments, domestic subsidence problems, complex city-centre developments and major contaminated land remediation schemes.

We apply the same high level of technical input and client care to any project with which we are involved. Allied to our technical expertise, and our ability to draw on our huge experience of working throughout the UK and abroad, is our understanding of the commercial environment within which we operate and the need to meet deadlines and to provide swift and clear responses to the important questions.

Above all, our advice is practical and pragmatic and the success of our approach is demonstrated by the fact that most of our work results from repeat business or personal recommendation. We have recently celebrated our first ten years of trading and have continued to grow through challenging economic conditions.
