Ground, Site and Soil Investigations

RGS undertake wide ranging and comprehensive ground investigations for a variety of clients.


The main industry sectors we work across are:

  • Industrial developments
  • Commercial developments
  • Residential developments
  • Insurance

We also can assist with:

  • Planning Applications
  • Services prior to and after Land purchase
  • Roads and Highways
  • Tunnels and Bridges

The right site investigation can in many cases, lead to project cost savings in the long term by allowing contractors to foresee problems, make decisions about remediation and proceed with all the facts and information relevant to the project and budget available.

There has never been a greater need to carry out proper site investigations. Many new developments are now being proposed on previously developed ‘brownfield sites’ and on ever more demanding greenfield sites. These sites are challenging and require thorough ground investigations.

We have a specialist team of highly qualified and experienced Geotechnical Engineers and on-site laboratory facilities to offer a site investigation service to assist you from the planning stages of a project right through to any required remediation solutions and completion of your project.

RGS uses a wide variety of site investigation techniques from desk studies to fieldwork and provides a bespoke service to suit any size of project. These include:

  • Analysis and Reporting
  • Cable Percussion Boreholes/Drilling
  • Concrete Coring
  • Dynamic Probing
  • Hand Pitting
  • Insitu Testing / Plate Load Testing / CBR Testing
  • Installation of Gas and/or Water Monitoring Standpipes, Piezometers and Inclinometers.

  • Retaining Wall Design
  • Rotary Boreholes/Open Hole/Cored Drilling
