Diamond drilling

Our main service concept may sound simple – we provide soil and rock samples by diamond core drilling from the desired location and depth.

Core recovery can be improved by the use of, for example, polymers.

We can also drill several branches from mother hole, which helps to spend resources to interesting sections and save time.

Our drill rigs can drill up to 2000 m depth, depending on the equipment used.
