Rotary drilling techniques are used when drilling into the rock is required to check for shallow mine workings or to test the quality of the rock.
Teckna Group own a fleet of Rotary drilling rigs suitable for many Geotechnical Site Investigations.
Our Rotary drilling rigs are all rubber track mounted to minimise damage to hardstandings and the surrounding areas.
We have a number of borehole drilling rigs to suit most locations and projects our smallest the Comacchio 450P is used for smaller sites, restricted access or domestic properties.
We then have Hutte 205GT to offer installations of up to 250mm casing to depths up to 100m.
Our larger rig a Comachio 900P.1 used for deep boreholes, is more than capable of installing deep cased boreholes.
Our Comacchio 900GT is capable of drilling and casing 150mm holes over 100m
Our rigs offer openhole drilling from 100mm to 350mm diameter and are used to locate shallow coal seams and for drilling dewatering boreholes.
