Don't just take our word for it

  • WJ provided a very good service, from the start of the proposed works...The drilling team who installed the wells were very hard working under difficult tidal conditions which were based on the 6hr working window in which they worked to a very high standard...Overall it was a good service by your company and i would have no hesitation in recommending to use you in future works.

  • We engaged WJ Groundwater to drill the new ground source energy well at UCL as they had successfully installed an abstraction well at the same site in 2014. This section of the work required careful planning to align with the main site activities. The WJ team carried out the works on programme and worked well with the main contractor to ensure that this logistically challenging project was delivered successfully.

    Iain Howley Director – University College London, Ground Source Consult Ltd
  • Very professional and have great technical and practical abilities.

    Con Hogan Project Manager – Anchorsholme, Ward & Burke Construction
  • WJ designed and installed an effective solution to control the groundwater for our basement excavation and deep core areas. Their work was carried out efficiently, safely and to programme

    Stuart Jackson Project Manager – RHSC, Brookfield Multiplex, Edinburgh
  • WJ’s installation team was excellent. The dewatering and groundwater recharge system worked as per WJ model & design. The works, including the Groundwater Treatment Plant setup and demobilisation, were carried out according to the programme. We received very good technical support with prompt production of monitoring data & reports.  Of special note was WJ‘s expertise in contractor assistance to mitigate risks for our forward planning.
