HWA operates an advanced Soil and Construction Materials Testing Lab as well as a Mobile Asphalt Testing Lab.  We test Soils, Asphaltic and Portland Cement Concrete, Aggregates, Geotextiles, and additional materials in support of site evaluation, structural design, and construction quality control.

Our laboratory is accredited by the American Association of State Highway and Transportation Officials (AASHTO) and the US Army Corps of Engineers (USACE), we participate in eight different performance assessment sample programs for soils, asphalt, and concrete through AMRL and CCRL, and our team of highly skilled laboratory staff hold several certifications from ACI and NICET.

Our primary testing lab generally conducts testing in support of soils characterization and field testing and inspection while the secondary testing lab conducts those tests mostly associated with geotechnical design.
