Solving Complex Problems With Concrete Solutions
Durability Engineers PLLC is a Chicago-based consulting practice providing specialized engineering services before, during, and after the construction of concrete structures. Its staff of engineers and scientists hold backgrounds in civil engineering, chemistry, materials science, and structural engineering. The practice specializes in three common concrete pathologies: Alkali-Silica Reaction (ASR), Delayed Ettringite Formation (DEF), and Pyrrhotite Analysis. It offers broader durability engineering, nondestructive testing, petrographic services, and structural evaluation and repair across critical infrastructure, including bridges, marine and coastal structures, water and wastewater facilities, and energy facilities.
Consulting services to identify, assess, and address concrete durability risks across new construction and existing assets, focusing on exposure conditions, deterioration mechanisms, constructability risk, and service life performance.
Deep-expertise consulting for complex concrete pathologies that cause premature structural failure, combining field investigation, laboratory testing, and tailored mitigation and repair strategies.
Work in this area is organized into supported delivery tasks.
Petrographic examination of concrete core and aggregate samples in specialized laboratories for the characterization and diagnosis of deterioration mechanisms such as ASR, DEF, and pyrrhotite oxidation.
Assessment and repair design for concrete structures experiencing deterioration or distress. Services include condition assessments, repair strategy development, repair design, construction administration, and construction oversight.
