“The East Midlands project has been one of the most high profile and logistically challenging contracts Colas have ever undertaken in the UK, and having everyone working together to ensure we delivered the outputs and quality required has ensured a fantastic outcome in completing in just 5 weekends.

We are delighted with the finished product. I would like to personally thank you all for the effort and commitment that you all provided for the East Midlands project over the past five weekends. All of your staff were great lads and working the long hours over the weekends they all performed admirably.”

As a preferred subcontractor of Aggregate Industries, Celtest have undertaken both site and laboratory testing on most of our major build schemes across the UK with great success. They have a good technical skill base and excellent site knowledge, from the guys in the office to the technicians on site. They're always there when you need them and a pleasure to work with.

''We have worked with Celtest regularly for over twelve years making use of their site testing and laboratory services. They are our first point of call as they always provide a professional, efficient and friendly service''
