Caisson | Vibepedia

Caissons are watertight retaining structures used in civil engineering, primarily for constructing foundations for bridges, dams, and offshore structures, or for underwater excavation. They are essentially large, prefabricated boxes or cylinders sunk to the seabed or riverbed, allowing work to proceed in a dry environment. Historically, caissons have been crucial for projects requiring deep foundations in challenging water conditions, enabling feats of engineering previously thought impossible. Their design and deployment are complex, demanding precise calculations for buoyancy, stability, and structural integrity under immense hydrostatic pressure. The evolution of caisson technology directly correlates with advancements in heavy lifting, concrete technology, and underwater surveying, making them a cornerstone of modern large-scale infrastructure development.
