A G Brown Drilling has been established for over 25 years. Our Company has worked on site investigation projects as large as Canary Wharf, The Millenium Dome, numerous motorways and by-passes, as well as The Jubilee Line and the Olympic site at Stratford.
We also have experience of working on sensitive sites such as Bacton Gas Terminal and Coryton Oil Refinary.
We have completed projects in Poland, Hungary, France and Belgium, we have also been involved in countless smaller projects from house extensions to complete new builds etc.
All of our lead drillers are NVQ qualified, have CSCS cards, are First Aid certified and have a cable avoidance tool operation certificate. They all also have at least 20 years drilling experience.
We also drill boreholes for environmental monitoring and audit work , using specialised clean drilling and sampling techniques and installing groundwater/gas monitoring wells.
Our extensive Site Investigation plant inventory includes Standard Shell and Auger Rigs , heavy duty Dando 3000 for deeper work, and Demountable Rigs for difficult access and low headroom locations (we can even gain access through a normal domestic doorway or garden gate, and can work at headrooms as low as 2.6 metres!)
Amongst our specialist equipment we also have an Electric Powered Drilling Rig which has been developed especially for sensitive indoor sites. This rig is very quiet and exhaust fume free. As an example of our expertise with this rig we have used it in basements of occupied buildings in London to drill boreholes to a depth of 50 metres without any complaints of noise or fumes. We have also successfully used this rig to drill a 30 metre borehole inside Bury St Edmunds Cathedral for the investigation work for the new tower. We have even used this rig and at an Oxford University where exams were being sat during the week of work! This rig is also a popular choice where drilling work has to be carried out near the general public such as occupied Shopping Centres.
We have the capability of drilling in 150mm, 200mm, and 250mm diameter boreholes.
