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 Cable Percussion, 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, plate bearing 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.

Our Core Values

At Oakland Site Investigation we pride ourselves on providing a quality and professional solution in every aspect of our 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.

Geotechnical & Environmental Associates (GEA) Ltd

The team at Oakland provide us with an outstanding, professional service across many of our sites, and have done so for over 5years.

Roni Savage BEng (Hons) Msc SiLC CGeol MCIWM FGS, JOMAS ASSOCIATES LTD

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

Steven Hill B.Sc.(Hons), M.Sc., CGeol, EurGeol, FGS, Terra Firma (South)

We have worked with Oakland for many years, their professional and hard working approach to site investigations means it’s always great to have their support on site. Oakland can always be relied on to attend site quickly providing a service to a high standard at competitive rates.

Sarah Cook MSci CGeol FGS, Leap Environmental Ltd

Ridge & Partners have used Oakland many times during 2018. We have found them to be extremely helpful when discussing potential projects, fast at quoting and efficient with their work on site. Works have included window sampling, trial pitting, soakaways, coring, foundation excavations and in situ testing, all of which have been carried out to high standards
