The Caisson foundation is a type of foundation. Caisson foundation. Well foundation is a type of deep foundation which is generally provided below the water level for bridges. A caisson can be a critical component of any construction project because it provides stability. It resists loads from structure through shaft resistance, toe resistance, and/or a combination of both of these. As with any construction project, the material to be used will depend on the function of the caisson and the type of caisson being constructed. Rubble mound breakwaters use structural Caissons may be open, pneumatic, or floating type; deep or shallow; large or small; and of circular, square, or rectangular cross-section.
