Stone Triangle Foundation — Detailed Guide
Triangular stone footing
ARK: Survival Ascended names this piece the Stone Triangle & Quarter Foundation, and ARK: Survival Evolved the 
Stone Triangle Foundation. In-game it says: "Required to build structures in an area. Triangle shaped." The ARK Wiki calls it the second triangle foundation to unlock. Foundations are what any housing or storage structure has to be built on.
Unlocking and crafting
The engram unlocks at level 24 for 6 engram points, with the 
Wooden Triangle Foundation as its prerequisite. Each one costs 40 
Stone, 20 
Wood and 15 
Thatch, and the ARK Wiki adds 
Fungal Wood as an alternative to Wood. A craft gives 7 XP, and in ASE it takes 5 seconds. A foundation weighs 2, and a full stack of 100 weighs 200. Our records list it on 14 maps and count 86 loot crate types that can contain it, such as the Aberration Blue, Aberration Purple and Aberration Surface Blue crates.
Laying a stone base
It can sit on even ground or on slightly uneven ground. Once the first one is down, more can snap along its edges and line up, as long as there is enough room and ground. It only supports walls, ceilings and similar pieces that sit directly on top of it. It can also hold up to 2 ceilings out along either horizontal axis and 1 diagonally, though the ceilings at the far end cannot carry walls. Destroying it brings down every piece that depends on it, and after a demolish, those extra pieces refund no resources.
Attacks that break stone
Stone structures take damage from a limited set of sources. Among those the ARK Wiki lists, with its percentages:
- explosives (150%), the
Cannon (~137%), the 
Tek Sword (~218%), the 
Ballista Turret (40%) and metal weapons (5%) - the
Titanosaur and the 
Defense Unit (~462% each), the 
DodoRex and the 
Dodo Wyvern (300% each), Alpha creatures and bosses (10% each) - creatures such as the
Arthropluera, 
Roll Rat, 
Deathworm and 
Magmasaur, plus Astral, Corrupted and Enraged creatures and the Titans
The 
Giganotosaurus (15%), the 
Tek Rifle (~50%) and the 
Rock Elemental hurt stone but not auto turrets.
