Adding a Foundation to a Seabase raises the integrity value by two units. Foundations are 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.
A wall-mounted variant of the Foundation exists. This can be built on the walls of natural terrain.
The blueprint for this item is unlocked by unlocking the Habitat Builder. It is crafted with the Habitat Builder.
