Projects often require a CPT rig for a variety of locations with varied terrain. This includes hardstanding sites (e.g. motorways, car parks) and off-road locations such as beaches and fields – as well as offshore and rail work, or basements where access may be restricted.

Our CPT Rigs

We have a variety of cutting-edge rigs to meet our client’s requirements and specifications. In addition to our CPT rig fleet, we also have our own transport for moving our rigs around the country. This enables us to have full control over our mobilisation and better serve our clients.

We have achieved Fleet Operator Recognition Scheme (FORS) Bronze level and are constantly striving to raise the level of quality within our fleet operations and to enhance our safety, efficiency, and environmental protection measures.
