Foundations

Foundations are tileable structures which can be used to make platforms for other buildings to be built on. When stacked on each other with adequate spacing, they can be used to build multi-story factories. They can't be painted, unlike other structures (Experimental: Painting of foundations is now possible).

Foundations create a grid for all buildings and allow for the construction of walls and walkways, allowing for efficient organization of factories.
