Triangle Foundation
Used to expand your raft on the bottom floor.

The Triangle Foundation is a block buildable with the Building Hammer in Raft.


The Triangle Foundation is one out of two foundations available in the game. Using the Triangle Foundation, the player may build diagonal lines on the raft. If the Shark attacks a Triangle Foundation, the player can destroy the foundation with an Axe and rebuild it instead of repairing it. Doing this uses no Material.

Building Triangle Foundations does not count towards the Builder! achievements.


  • Can be used to expand the Raft diagonally.
