Intégrale have been verified as a Supplier on Construction Line (the first benefit of which is that we are working on a fantastically interesting historic building conversion project in Oxford). We are currently validated under Ground Investigations and Geotechnical Works (Site Investigations), but will be looking to expand this over time. Please do call Andy or Chris on 01275 333 036 if there is anything we can help you with.

Understanding Ground Conditions on Bath hillsides

We always love working in and around Bath – not only a beautiful historic city, but it holds a plethora of ground related challenges that we’re frequently asked to investigate and overcome.

Recently, Intégrale investigated conditions beneath a proposed private residence in Kingsdown, in a fantastic hillside setting.  Having identified the site as underlain by ancient landslip soils, we designed phased investigation, culminating in deep cored boreholes and computer analyses to ensure stability of the new house.  A robust contiguous piled wall will maintain sufficient lateral support and ensure long term stability.

Such stability assessments don’t always require expensive deep boreholes.  We also complete preliminary stability analyses, using our wealth of experience in landslip ground conditions gained over 30 years.  We’ve recently helped a number of private and commercial clients develop their projects from garden rooms to cider barns!  If you or your client are considering construction on a sloping site, get in touch to chat through possible ground conditions and the range of investigation and foundation solutions.

Welcoming Jane

To help with the ongoing increase in workload, we welcome Jane Haley to Intégrale as Admin Assistant.

Jane’s previous experience working with the Environment Agency, keen eye for detail, and high level of professionalism will be hugely beneficial to ensure we maintain our high reporting standards!


August and September have been exceptionally busy for Intégrale, and we are delighted to welcome back Chris Whale as Geotechnical Principal and Director Designate. Chris has almost 25 years of experience, previously working for Clarke Bond in Bristol, and 12 years before that, he worked here at Intégrale!
Chris’ apparently unlimited energy, vast experience, and no-nonsense attitude will ensure Intégrale maintain and improve technical output.
Chris will partner Andy in managing our Bishop Sutton office, and provide high level geotechnical and contaminated land support to clients and junior staff alike. To contact Chris, please call the office on 01275 333 036, or email him on

Welcoming Phil

We are delighted to welcome Phil Cresswell to the Intégrale fold. Phil previously worked at Aspire Defence, as Environmental Advisor, managing a broad range of environmental projects during the construction of new accommodation for military personnel.

Happy 30th Birthday Intégrale!

Report front cover

How time flies. Starting in 1987, Gareth Thomas set up Intégrale on his own, to provide high end geotechnical support and advice to a wide range of clients. Since then, the company and industry have changed, but Intégrale still provide that same level of high end geotechnical (and contaminated land) support. To celebrate, we have developed a new logo and corporate image, and we hope you like what we have achieved. The new report types will be issued from August. Let us know what you think!

Gone but never forgotten



After 12 years of loyal and dedicated service to Intégrale, our Office Manager, Julie Matthews, has decided to retire. Almost all of our clients will know Julie, and we’re sure you will join us in wishing her all the very best for her well earned retirement! The team at Intégrale thanked her with a celebratory meal at The Pig near Bath as well as some vouchers for a deserved holiday. Stepping into Julie’s shoes is Laura Dury, who will continue to provide great support for the technical team, and our clients.
