Laboratory Testing & Gas Monitoring

Digging underground and retrieving samples is the first crucial component of ground investigation. Next comes testing the samples to meet the highest quality standards available. That’s what happens in our UKAS-accredited laboratory at our headquarters in Yorkshire, where qualified technicians take sampling very seriously, uncovering data our clients can rely on to create a detailed picture before their build begins.

Geotechnical laboratory testing

  • Soil classification

  • Chemical testing

  • Compaction related tests

  • Compressibility of soil

  • Shear strength of soil

  • Permeability tests

  • Rock tests

  • Aggregate tests

Chemical laboratory testing

  • Contamination testing suites

  • WAC analysis

  • Individual chemical tests

  • Landfill/mines gas and/or groundwater level monitoring

All kinds of risks in the ground can impact a build – poor soil quality, hazardous chemicals and gasses. Construction planners, architects, developers and builders must consider those risks and many more before setting teams to work on a site. 

That’s the difference with RGS, where both sampling and testing happen in tandem at our UKAS-accredited laboratory, providing a complete service to our clients needing critical and accurate information delivered quickly.

Some natural ground gases are hazardous – toxic, odorous and flammable. Whether they are formed naturally (peat deposits) or man-made (the result of landfill), it is critical to recognise when they are present in the soil as they pose an issue to any planned construction work.Gas monitoring takes place periodically to assess the risk of any gas over time. It is best carried out under different weather conditions to see how this affects the area. Talk to our team if you are concerned about ground gas at one of your sites.

All testing is different – some samples are quick to test, and others require a more detailed assessment over time to conclude a result. Your nominated RGS Project Manager will confirm the expected timelines for your laboratory testing service before it begins and update you on any changes.

    Surveying & Risk Assessments

    Understanding the lay of the land is critical when you're planning or constructing a building. Surveys are the starting point for many geotechnical projects, giving you a detailed view of the proposed site - from size limitations to flood or drainage risks - and RGS has the knowledge and topographical tools to help!
