Karla A. Salahshour

Senior Associate


Since joining WJE, Karla Salahshour specializes in the evaluation and characterization of historic and modern building materials. Her work in WJE’s Cleveland materials laboratory focuses on the petrographic examination of concrete, mortar, grout, brick, stucco and plaster, natural and manufactured stone, and other construction materials. Ms. Salahshour’s laboratory work has included investigating the causes of distress in construction materials, characterization of cementitious materials, and the evaluation of durability concerns in hardened concrete.

Ms. Salahshour also conducts field evaluations, that often grade into laboratory testing, such as evaluating distress in concrete slabs and pavements and evaluating the performance of flooring and coating systems, and investigating distressed reinforced concrete structures. Her field experience also includes the investigation of stone cladding panels, mass masonry structures, terra cotta facades, EIFS and stucco systems, and terrazzo. These field evaluations often grade into laboratory testing.
