Clients

Testimonials

Client

⭐⭐⭐⭐⭐

I used Ashdown Site Investigation Ltd and was thoroughly impressed with their approach. They provided superb value, the company was easy to deal with and the on-site crew were really great too! The Geotechnical Assessment Report as provided was thorough, and was exactly what our structural engineer required. Thank you again.

Structural Engineer

⭐⭐⭐⭐⭐

I have worked with Ashdown Site Investigation for many years since their infancy. The amount of projects that we have worked on together are therefore too many to count. On all of these projects we have always received great technical advice, and have received good clear technical reports on time. When quoting for projects they are normally very competitive too. We always recommend Ashdown to our clients when they need Geo-technical and Environmental Investigations.
