Join us on site!

One thing we’ve learn’t over our 19+ years of drilling across the UK –  no two projects are the same. That’s why we’ll approach your project with a wealth of knowledge and experience.  If you’re curious about how we do it, take a look at our images and videos below.

Definitely looking forward to passing on more work if this is how you operate.

One of our latest projects in Northamptonshire:
A water borehole to Fill a large pond

Our customer wanted their own leisure pond, we drilled 100m to help create their vision. We’re proud to say they gave us this fantastic review!

Having moved to a new house we wanted to reinstate a substantial pond on our land. We used GSI and their team to drill a borehole. They installed a pump to access water from an aquifer we’d identified. After 100m of drilling we finally struck water and successfully achieved a flow of around 20,000 litres a day, allowing us to achieve our vision of the pond you see in the picture. 

We’ve never undertaken such a project before and needed to be handheld through the process. The team did very well and gave us the assurance we’d get the outcome we needed. 

Even when our pump stopped working it was removed and replaced under our warranty, without fuss and in a timely manner.
