At CMTL, our UKAS and INAB 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
- Comply with the relevant British and European regulations and quality standards
- Enable informed decisions on construction materials required from test results
- Identify the characteristics of soil on site to determine its ability to support your construction project
- Identify the different soil types on site and their location
- Gain the data necessary to support planning permissions and license applications
UKAS & INAB Accreditation
Our on-site pop-up laboratories are UKAS & INAB accredited and enable fast analysis for a more cost-effective, time saving testing solution.
