Geotechnical Engineering in Jefferson County, CO

Around Jefferson County, bentonitic clays heave slabs and flatwork wherever moisture control and compaction testing get skipped. Foundation recommendations for Jefferson County projects start from measured soil behavior, giving Colorado designers the inputs calculations actually need. Consolidation and strength testing on Jefferson County samples quantify settlement, before CO designs inherit a surprise. Multi-state industrial clients bring us into Jefferson County for defined programs, and Colorado requirements are settled before mobilization, not after.

  • Soil borings and sampling programs sized to the structure and site
  • Laboratory index testing: Atterberg limits (ASTM D4318), moisture content (ASTM D2216)
  • Moisture-density relationships and bearing evaluation for foundations and pavements
  • Expansive-soil characterization for slab and pavement design
  • Construction-phase verification: proof rolls, subgrade acceptance, fill placement observation

FAQ · Jefferson County

Do I need a geotechnical report before building?

Most commercial permits, lenders, and structural engineers require a geotechnical report to establish allowable bearing pressure and foundation type. It is the least expensive insurance a foundation can have.

How long does a geotechnical investigation take?

A typical light-commercial site runs one to two weeks from drilling to final report, depending on lab test turnaround and access conditions.
