We have used GSI to drill our private water well behind our house. We are delighted with the work they have done. When our Water Well was completed you could hardly tell that there was a drilling machine in our back yard. They left everything clean and tidy. If anyone looking to drill a water well I would highly recommend these guys. Great work. R. Allan
We have used GSI for all of our geothermal bore hole drilling projects for the past 7 years. We find GSI totally dependable, honest and never go back on their price, even in tough ground conditions.
Gretton Site Investergation has drilled several GSH projects for us in central London, they have just completed an 11 x 150m project in a very restricted area in central London. We find them very experienced and hard working, their equipment is well maintained, method statements and HSE requirements are all covered. And I am looking forward to working with them on our next project.
