Soils and Aggregates

MTI provides fill placement monitoring, density testing, geotechnical observations, and many other soils related services. These services are performed during excavation activities and serve the purpose of qualifying all load bearing surfaces or areas, as being in accordance with the project requirements and/or able to provide the necessary bearing that has been specified.

  •     Fill Placement Monitoring - Visual monitoring of fill placement lifts to ensure that materials and placement procedures are in accordance with project soil reports and/or specifications.
  •     In-Place Density Testing - The use of a nuclear-densometer to determine optimum moisture content and in-place density of soils.
  •     Subgrade Inspections - Geotechnical observations made to ensure that structural assemblies are bearing on suitable subgrade materials, and to identify other potential structural issues.
  •     Geosynthetic Membrane Placement - Professional overview of geosynthetic membrane installation procedures in accordance with industry standards and specifications.
  •     Pile Driving and Caisson Placement - Monitor pile driving and caisson operations and to verify compliance with the project requirements and/or geotechnical engineering report.
  •     Laboratory Testing – Each MTI office has a fully staffed and equipped laboratory facility to handle all necessary off-site testing requirements. The labs provide testing to support field personnel with tasks such as moisture density curves (proctors), California Bearing Ratios (CBRs), fracture face counts, gradations, etc.
  •     Aggregate Source Evaluation/Suitability - The evaluation of mined aggregate to determine its properties, characteristics, and suitability for its intended use. This includes borrow source, pit source, and on-site source evaluations.
