Land Drilling, Civil Engineering & Site Investigations
Oakland Site Investigation was formed in April 2012 and has established itself as a leading sub-contractor within the Site Investigation industry. We have two offices, our main office is in West Sussex and we have another successful office in Hertfordshire. The director’s John Essam and Tom Clarke, have over 30 years combined experience carrying out ground investigations, delivering a wide range of site services to the industry
We now run 8 windowless sampling rigs, along with other equipment including coring rigs, hand held window sampling, towable 2500 litre bowsers for soakage testing as well as both hydraulic and electric breakers and hand digging equipment and CBR testing.
We are an accredited member of CHAS, all lead drillers hold NVQ Lead Driller cards in Land Drilling, we have both superviser and operatives in Streetworks and all of our workers hold CSCS cards. This is important to us for keeping high standards both in our work and our approach to work.

What our client say

The Oakland team have worked alongside our engineers on our site investigations for many years now. They are usually our first ‘go to’ team for help with our fieldwork, as we know they will give us a professional and helpful service, especially if our works/clients prove to be a little difficult, they will always go that ‘extra mile’ to try to find an amicable solution. Their well-trained, friendly and experienced staff are a pleasure to work with.

We have used Oakland SI for many years now, primarily for mini-percussive drilling but also for inspection pits and monitoring services. We have always found them to be professional, knowledgeable and very helpful. Their positive attitude is invaluable and is why they are our go-to drilling contractor in the South East and Midlands
