Laboratory Testing

ALLWEST can provide cost effective quality control/quality assurance services to meet our clients’ needs. We are proud of our laboratory staff’s ability to produce accurate, representative test results in a timely manner. ALLWEST maintains national accreditation in our Spokane Valley, Washington office from the Washington Association of Building Officials (WABO), and in our Hayden and Lewiston, Idaho offices through AASHTO Materials Reference Laboratory for a wide variety of construction materials testing procedures (http://www.amrl.net/amrlsitefinity/default/aap/r18labs.aspx).

ALLWEST also maintains an accreditation from the Idaho Transportation Department (ITD – Lewiston and Hayden, Idaho). In addition, ALLWEST has an up-to-date laboratory trailer for testing at remote projects. Our trailer is certified by ITD and is set-up for testing during crusher control, soils, and asphalt.
