Geoprobe 7822DT

Geoprobe 7822DT

To increase our drilling capabilities and contaminated land remediation services we purchased a new Geoprobe® 7822DT from Geoprobe Environmental Technologies in Belgium back in 2011. This was the first of this new model in the UK which is owned and operated by an independent drilling contractor and it is the largest and strongest Geoprobe® unit available in the country.

This rig is a high capacity direct push machine with a narrow tracked base for good manoeuvrability and for use in limited access areas. It is equipped with a strong rotary head for augering, giving flexibility and versatility in its drilling capabilities. It has been factory fitted with an interlocked rotary guard to comply with UK HSE requirements.

Using Geoprobe’s wide array of high quality tooling options we can offer services including:

  •  lined soil sampling
  •  grab water and soil vapour sampling
  •  installation of wells by direct push as well as hollow stem augering techniques
  •  direct injection of in-situ remediation products
