At CMTL, our UKAS accredited laboratories are well-equipped to provide soil testing services for projects which have a large soil testing requirement. Our flexible scope laboratories provide a bespoke and cost-effective solution for soil sampling, enabling a fast turn-around of accurate and informative results.

The properties identified in soil can hugely affect both structural design and the construction materials chosen for use in engineering projects. Testing for soil strength, density, compaction and contamination data, as well as determining the chemical properties, are vital to making good decisions during the construction process.

Benefits of Soil Testing

  • white tick icon Comply with the relevant British and European regulations and quality standards
  • white tick icon Enable informed decisions on construction materials required from test results
  • white tick icon Identify the characteristics of soil on site to determine its ability to support your construction project
  • white tick icon Identify the different soil types on site and their location
  • white tick icon Gain the data necessary to support planning permissions and license applications
UKAS Accreditated Laboratories

Full UKAS Accreditation

For larger, ongoing projects our on-site pop-up laboratories are fully UKAS accredited and enable fast analysis for a more cost-effective, time saving testing solution. All our on-site and laboratory tests are performed under our UKAS accreditation.
