Local conditions
Forensic conditions in Hawaii County
Hawaii County presents building conditions found almost nowhere else in the United States. Active volcanic geology on the Big Island creates highly variable basaltic substrates, expansive ash-derived soils, and lava-flow terrain whose bearing characteristics can differ dramatically across a single project site. Coastal exposure brings persistent chloride-laden humidity that accelerates reinforcement corrosion, while tropical rainfall cycles impose continuous moisture and thermal stress on concrete structures, pavements, and foundations. When distress appears — cracking, settlement, spalling, or structural movement — pinpointing the cause requires disciplined field investigation, careful evidence preservation, and rigorous laboratory analysis. Our technicians, dispatched through our Sacramento regional hub, perform systematic coring, sampling, and in-situ documentation following established chain-of-custody protocols. Licensed engineers then evaluate the physical evidence and render professional opinions suitable for design correction, owner disputes, or legal proceedings. The laboratory operates under a documented quality system, providing defensible data at every stage of the investigation.
Basaltic lava rock and volcanic cinder soils common across Hawaii County can complicate conventional bearing capacity assumptions, and corrosion of embedded reinforcement is a persistent concern given the island's high-humidity, salt-air coastal environment — both factors that commonly appear in foundation and concrete failure investigations.
FAQ · Hawaii County
How do you core through basaltic or lava-rock substrates without compromising the sample integrity?
Diamond-core drilling suited for hard volcanic rock is selected based on substrate conditions identified during the initial site assessment. Cores are documented with photographs, logged for discontinuities, and sealed immediately to preserve in-situ moisture. Extraction follows ASTM C42 procedures to maintain geometric integrity and chain of custody, ensuring the sample reflects actual field conditions rather than drilling artifact.
Chloride-induced corrosion is common near the Kona and Hilo coastlines. How do you investigate it?
Investigation includes concrete coring followed by chloride profile testing per ASTM C1202 (rapid chloride permeability) and titration methods per ASTM C114. Half-cell potential mapping per ASTM C876 helps characterize active corrosion zones. These results, combined with cover depth measurements and rebar condition documentation, give licensed engineers the evidence base needed to assess corrosion extent and probable cause.
Tropical rainfall causes frequent wet-dry cycles on the Big Island. Can moisture history affect a forensic concrete investigation?
Yes. Cyclic wetting from Hawaii County's high-rainfall zones, particularly on the windward Hilo side, can mask or alter crack patterns and affect carbonation depth readings. Field documentation captures current moisture conditions, and petrographic examination per ASTM C856 identifies microstructural evidence of historic moisture cycling, helping engineers distinguish original construction defects from long-term environmental deterioration.
