Specialist drilling and grouting

Carnon Contracting has a long history of solving difficult drilling challenges. The company’s substantial experience means it is well placed to offer professional and practical answers to unusual drilling projects. Whether the problem relates to the geology, the ground conditions or a difficult location, we will find a solution to meet your needs.


Projects we have completed include:

• The installation of sewage outfall through cliffs at Mevagissey and Perranporth in Cornwall, UK
• The installation of piezometers in an earth fill dam in Cornwall for the Environment Agency
• The drilling of blast holes on the seabed in Pembroke Dock, West Wales, for Fugro Seacore from their jack-up rig
• Pressure-released drilling in the Victorian dams of the Elan Valley in Mid-Wales for Severn Trent Water
• Pressure-released drilling in the Bartell and Roadford dams for South West Water
• The drilling of deep instrumentation holes for rail track at Coal Pit Heath, Gloucester, involving working in an unrestricted speed section of railway line

In conjunction with drilling operations carried out by our own rig fleet Carnon Contracting can also offer grouting as a solution. We can provide a range of cementitious grouting techniques to assist and remediate the following problems:

• Ground improvement and soil stabilisation grouting for enhancement of the mechanical properties of the soil and remediate problems associated with subsidence
• Under-slab grouting
• Fissured rock grouting typically performed in downward phases
• Void filling to eliminate collapses, sink holes or depressions associated with deformation of the ground surface. In particular old redundant underground services and mining features.
• Structural steel and foundation grouting
• Precast concrete grouting for panels, barriers, and columns and associated connections
