Thorne Civil Engineers
In the fast-paced, exacting world of civil engineering, you need a partner you can trust to deliver quality work, consistently and cost-effectively.
CJ Thorne & Co have provided exceptional civil engineering services across the south east since 1939.
From our origins constructing playing fields for local councils, we developed our expertise to specialise in water engineering, infrastructure projects and environmental works. This integration of multiple disciplines enables us to offer a “one stop shop” solution for our clients.
We are proud to be the first choice as principal civil engineering contractor for many high-profile projects. Our clients appreciate the value added by our fully owned plant and vehicle fleet, which we maintain ourselves. This is supported by the consistently excellent, ISO-certified service from our directly employed workforce, both on site and in our offices.
