The Foundation is a Seabase component intended for other modules to be built on top of. The Foundation is constructed with the Habitat Builder, requiring two Titanium and two Lead.
Adding a Foundation to a Seabase raises the integrity value by two units. Foundations are one of the easiest way to add Hull Integrity, as they are relatively cheap and don't need to be installed in a specific compartment. Another way to increase hull integrity is to build Bulkheads or Reinforcements.
