Karla A. Salahshour

Senior Associate


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 investigates the causes of distress in construction materials, characterizes cementitious materials, and evaluates 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 as well as investigating distressed reinforced concrete structures. Her field experience 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.
