ISI operates a 10,000 square foot full-service Materials Testing Laboratory in Berkeley, California. Testing is overseen by a professional registered engineer and conducted by certified laboratory technicians (NICET, ACI, CALTRANS). Our Berkeley laboratory is accredited by the AASHTO Accreditation Program and by numerous state and federal agencies including:
- Caltrans – California Department of Transportation

These accreditations include on-site inspections of the laboratory, review of the lab quality control manual, lab equipment calibrations, maintenance schedules and lab testing procedures. The ISI laboratory also participates in reference sample programs for asphalt, concrete, soil and aggregate, administered by the above mentioned state and federal agencies. This program compares the quality of ISI test results with laboratories across the nation or state, depending on the certifying agency.
