Our rigs are owned, operated and maintained in-house from our facilities in Gloucester. Each of the rigs has its own specification, and in some cases, we have multiple rigs of the same make and model. If you need advice about the best rig for your project, get in touch.
All of our rigs have a unique QR code which allows our clients and staff to access all of the necessary compliance documentation. That includes calibration certificates and certificates of thorough inspection, making audits a dream.
Our Fraste multi-purpose drilling rigs are ideal for geotechnical and geo-environmental site investigations. The rigs are capable of drilling boreholes using conventional rotary coring and wireline Geobor S, up to 100m in depth. With in-situ calibrated standard penetration testing (SPT) and undisturbed sampling (U70, U100 and UT100). Class 1 samples (EN ISO 22475-1) can be prepared from the core by one of our engineering geologists.
Operated by a two-person crew, the CP rig is versatile and cost-effective at drilling geotechnical boreholes in larger diameters through made ground and coarse superficial deposits achieving depths of 70 to 80m.
Having our own cable percussive rigs makes arranging rotary follow on much easier and less time delays for our clients.
A small 1-tonne rig capable of drilling up to 12m in soft soils using a duplex-cased dynamic sampling system. Operated by a two-person crew, it is a great way of rapidly forming site investigation boreholes.
Our LMSR-H modular dynamic sampling and probing rig provides the perfect solution for drilling at limited access sites such as on the railway, basements, the crest or foot of a slope, inside buildings or any other areas inaccessible to tracked, or wheeled, rigs.
The components of the rig are carried to the borehole and then re-assembled; it has the same basic capabilities as our larger track-mounted Terrier rigs, using the same duplex-cased dynamic sampling system, it can achieve depths of up to 10m depth
Our Vector HDD650 vacuum excavation system uses a high-power vacuum suction system to excavate soils or other materials during ground investigation projects. It is mounted on a 7.5-tonne flatbed and has a separate 36hp diesel engine. The system is intrinsically safe with a shutdown button, chalwyn valve (positive air shut-off) and spark arrestor.
Vacuum excavation can reduce the risk of damaging buried services, including cables, pipes, drains and culverts. It also allows for excavation in areas of a site otherwise inaccessible to traditional plant. This technology can also be used as an alternative to manual hand digging, protecting site operatives by reducing manual handling and increasing the rate of progress for an excavation programme.
