About Us

Ashdown Site Investigation was established in 1989 and is recognised for providing high quality site investigation and ground investigation services.

Originally based solely in the south east of England, we now deliver services across the country from our offices in East Sussex and Manchester.

We have a team of highly qualified and competent staff who are fully conversant with current guidance and industry standards. We maintain this position by continuously investing in staff training and development.

We operate an integrated quality and environmental management system, accredited to both ISO 9001:2015 and ISO 14001:2015. We are registered on Constructionline, Acclaim (SSIP) Accreditation and Builders Profile and are members of the Association of Geotechnical and Geoenvironmental Specialists (AGS).
