Alkali-Silica Reaction Residential Home
CA was retained in order to investigate the long term performance and possible remediation alternatives for the cast-in-place concrete slab-on-grade foundation at the residence affected by alkali-silica reaction (ASR). Shortly after placement, the foundation exhibited signs of ASR by exuding the slippery gel product throughout the slab causing a safety hazard for the owners. CA was tasked with determining the extent of the damage as well as provide a set of guidelines for repair. CA’s investigation consisted of document review of concrete delivery records, photographic evidence of the site, litigation documents, concrete sampling, petrographic examination, and three site visits to the residence.
