Cracking, water leakage, efflorescence, and brown residue at a reinforced concrete tunnel wall raised concerns about embedded steel and the extent of deterioration within the section. This investigation used field testing and exploratory coring to evaluate corrosion risk and help define where further attention was needed.

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.

From chain drag to petrography, see how a targeted condition assessment turned scattered symptoms into a prioritized repair and coating plan for a post tensioned parking deck.

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.
