At first glance, the Saratoga Creek Bridge stands as a quiet, historic landmark nestled among redwoods. But beneath its stone arches, a deeper story was unfolding—soft concrete, hidden voids, and signs of corrosion threatening its long-term stability. Concrete Science, Inc. was called in to uncover the unseen. Through advanced petrographic analysis, chemical testing, and meticulous fieldwork, the investigation revealed critical structural vulnerabilities and environmental threats.

Comprehensive fire damage assessment of bridge girders, evaluating structural integrity through pulse velocity testing and petrographic analysis. Findings identified critical areas of deterioration, guiding targeted repairs and long-term rehabilitation strategies for restoring concrete durability.

Case study analyzing extensive concrete spalling and rebar corrosion at the Hall of Records building. Findings indicate corrosive soil, high chlorides & sulfates, and carbonation as primary causes of deterioration. Evaluation involved NDT, core testing, and chemical analysis. Conceptual repair options and recommendations are discussed, including the use of FRP to strengthen cracked columns.
