WJE has significant experience assessing corrosion-related deterioration in a variety of materials, structure types, and environments—including reinforced concrete, structural metals, and piping. WJE uses extensive in-house field and laboratory testing and modeling capabilities to detect and assess corrosion. Whether evaluating corroded reinforcing bars in a concrete bridge deck, or section loss in a weathering steel beam, or premature failure of water supply system, or the integral metal parts of a manufacturing process, WJE’s comprehensive chemical and physical testing capabilities provide clients with information to make sound design or repair decisions.
In addition to mitigating current corrosion issues, WJE can project the likely rate of corrosion over time using models developed from data collected through visual inspections, sampling, and laboratory testing. Service life modeling allows clients to adequately prepare for their structure’s future repair and maintenance needs.
With over thirty years of hands-on research experience for both private-sector and government clients, WJE is well-equipped to diagnose and counter the effects of corrosion.
