Rig versatility drilling back under tracks

Grouting Services owns and operates 5 purpose built track mounted drilling rigs and has the capability to drill holes ranging from 75mm to 300mm diameter, and depths up to 50m.

A full complement of drilling accessories including compressors, pumps and water tanks is also maintained in house.

A range of proven drilling techniques are available including:
Rotary wash drilling
Percussion hammer drilling
Overburden casing (concentrix) system
Continuous flight augers

Difficult access is catered for with the ability of all specialist rigs to drill back underneath the tracks at varying angles of inclination ranging from 5degrees to 90degrees below the horizontal, and, depths below the ground surface up to 4m. The specialist rigs are also able to safely drill up to 5m above the drilling platform. Drilling in areas with restricted head room up to 2.5m is also possible.

We provide cost effective drilling solutions for ground anchors, soil nails, micro-piles, horizontal drains and foundation proof drilling in rock.
