Info
Airlocks are structures effective at preventing water (and mobs) from spreading into buildings. The airlocks shown here will close in the event of flooding, but will not reopen until the player breaks them. The designs shown here are not true airlocks, but are simply watertight compartments to close in the event of flooding. Using a door is more like a true airlock.

For the entity that items and blocks turn into when dropped, see Item (entity). For the items that mobs leave behind on death, see if the block it is attached to is removed or if it is exposed to water.
- Sand will always attempt to fall and can be supported by a torch.
- Water flows outwards, but will dry up if not connected to a block of still water.
When a torch with sand on top of it touches water, the sand drops and stops water flow in that direction. If torches are attached to any of the blocks above, then that torch will break as well. This will continue to the very last torch.
Design 1
An airlock requires only two components, a block affected by gravity (such as sand Sand Transparency No Luminance No Blast resistance 2.5 Tool Renewable No Stackable Yes (64) Flammable No Experience Smelted: 0.1 Drops Itself Data values Sand dec: 120 hex: C0 bin: 11000 Red Sand dec: 121 hex: C1 bin: 11001 Name sand This ) and torches (regular or redstone Redstone Torch Transparency Yes Luminance Yes, 7 (when on) Blast resistance 0 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Drops Itself Data values See Data values Name See Data values This article ). When placing an airlock, be sure to think about choosing narrow passageways and choke points, so that less time is spent on the project. For a building with multiple entrances, multiple airlocks may be needed to achieve optimal dryness. Airlocks are usually built directly across the hallway. Most sand-based airlocks are only 1 block thick, due to the fact that only 1 layer of sand is needed to stop the water.
Determining the materials needed is simple enough. The number of torches is equal to the width of the corridor, and sand is equal to the width of the corridor times the height of the corridor. Optionally, a shovel and a pickaxe can be taken along, to speed up digging and to waste less time on mistakes.
For the first step, the hallway must have a ceiling height equal to the highest water level possible plus 1, to compensate for the torch. Also, each new column must be 1 block higher, as the torch is 1 block higher each time. A torch is placed on either wall at a level where water can contact it and there is enough space above to provide the required amount of sand to seal the chamber. Sand is now placed above the torch until the sand reaches the ceiling, or until it reaches the desired level.
(A 1 block See the various blocks found in Minecraft. For the blocking with shields that reduces damage when performed, see Blocking. All blocks Blocks are the basic units of structure in Minecraft. Contents 1 wide hallway is complete at this step)
A passageway more than 1 block wide must be extended from wall to wall in a particular fashion. A torch is placed on the block of sand above the previous torch, and sand is placed above that. This process is repeated until the hall is waterproofed.

Design 3
Since the introduction of pistons Piston Transparency Yes Luminance None Blast resistance 2.5 Tool Any tool Renewable Yes Stackable Yes (64) Flammable No Drops Itself Data values See Data values Pistons are blocks capable of pushing most blocks, depending on , they can be used to make much more compact airlocks using the same basic techniques. Piston-based airlocks are not restricted to using sand or gravel, but they may require redstone circuitry which tends to make them costlier and more complex than torch/sand or torch/gravel airlocks. A simple way to build one would be to make a piston system that is retracted when the current is stopped and then placing redstone across the passage.
Other Uses
Airlocks are one of the first completely environmentally reactive traps This list doesn t cover mob grinders, the killing mechanism in mob farms. Traps are a common mechanism in Survival Multiplayer (SMP) built by players to kill other players or mobs automatically. The following is a in Minecraft.
The use of Airlocks in stopping water flow can also be applied to the concept of controlled flooding, allowing one to flood an area until a certain water level or redirect it when those levels are reached.

The airlock works essentially the same, but faster and directly controlled by water flow, and not player interaction (Making it a completely standalone mechanism), Although this video proves that the method can be used to effectively trigger multiple walls and seal off multiple areas.
