What Our Clients Say

"Ours was a site which presented particular challenges, in terms of limited access for specialised equipment, restricted operational space and sloping terrain.

At all times, the Synergy Boreholes team worked with enthusiasm, absolute professionalism and dedication to the task in hand. The positive impression I gained when they came to survey the site was confirmed during their period on the project.

They provided regular status updates, gave me clear explanations of potential problems encountered during drilling and came up with solutions that enabled us to complete that phase of work on time and within budget.

I would commend Synergy Boreholes without hesitation.
