Laboratory Facilities

WDP has extensive laboratory facilities for conducting standardized (ASTM, AASHTO, etc.) and specialized testing and analysis of concrete, masonry, steel, soil, and other construction materials.

This testing may be conducted to determine material properties of proposed materials in new construction projects, establish material properties in existing structures, or to investigate material failure and performance problems. In addition to equipment to test strengths and other physical material properties, WDP’s laboratory includes facilities for mechanical testing, cyclic environmental testing, chemical analysis, microscopy and corrosion testing. The lab is inspected regularly by the US Army Corps of Engineers and is accredited by WACEL.
