Lab-based Soil Stabilisation Services

Simtec's UKAS accredited laboratories are well-equipped to provide a comprehensive range of soil testing services for even the biggest projects. The central location of the facility in the Midlands also means it is ideally placed for the rapid delivery of samples.

Ground Investigation & Procurement 

Desk studies are available to

  • Review the available soil data
  • Assess the potential of stabilisation
  • Analyse trial pit samples in the laboratory
  • Establish if detrimental levels of sulphates are present
  • WAC (Waste Acceptance Criteria) testing / EWC Classification
  • Asbestos ID testing (including quantification)
Aggregates Testing on site

Laboratory Trials

Laboratory trials should be conducted prior to any full-scale field trials, or the laying of material is carried out. We carry out a range of tests to assess host soil properties and offer improvement to stabilised materials following the addition of appropriate binders.

Plasticity Index (Atterberg Limits)

The soil characteristics that most affect the behaviour of placed earthworks material are the Atterberg limits which consist of a plastic limit, a liquid limit, and the calculated plasticity index. Some materials will not perform adequately in certain situations, so it’s imperative to classify the soil before use.
