WHO ARE GA SITE INVESTIGATION LIMITED?

Formed in August 2009, and with over 40 years’ direct experience in the site and ground investigation industry, GA Site Investigation Limited is an independent site and ground investigation company providing professional, cost effective investigations. We tailor the investigations around clients’ and statutory authority requirements, for the safe and effective investigation and development of Greenfield and Brownfield sites.

Having developed our skills from working with numerous consultants, designers, engineers, architects, builders and expert witnesses to provide detailed site specific geotechnical data for their required use, including specialised subsidence and heave litigation cases, we utilise these skills to ensure all our clients receive the same high quality service.

From property extensions through to new build housing, commercial or industrial developments, building and ground movement/stability issues, retaining walls, or any site where subsurface ground conditions need to be proven as part of the development or movement investigation, our team is dedicated to providing all our clients with the same high level of service, no matter the size of the contract.

We are CHAS, Constructionline and Safe Contractor Accredited.

For boreholes and ground investigation for any type and size of development, we can offer advice and free no obligation quotations.
