Direct answer

The Shovel and Gun cannot damage Crackstone. Use another digging tool; the Rocket Launcher is a directly confirmed option.

To break Crackstone in Sandustry, use a digging tool other than the Shovel or Gun. The Rocket Launcher is the clearest directly confirmed method: its official page specifically names Crackstone as terrain it can destroy.

| Tool | Works on Crackstone? | What the official source confirms | | --- | --- | --- | | Shovel | No | It does not affect Crackstone. | | Gun | No | It does not affect Crackstone. | | Rocket Launcher | Yes | Its explosions can destroy Crackstone. | | Other digging tools | Yes | The Crackstone page says all digging tools other than the Shovel and Gun can destroy it. |

Stone or Sandstone?

Some players reach this guide after searching for “stone” or “sandstone,” but the current official source calls the hard material Crackstone. It does not confirm that Sandstone is an official alias for Crackstone.

Check the in-game material name before applying the advice below. If the target is not Crackstone, its tool requirements may be different.

Why your current tool does nothing

Crackstone cannot be damaged with the Shovel or Gun. Other digging tools can destroy it, and breaking it produces no drop. If one of those two tools has no effect on material you have identified as Crackstone, that result is expected rather than an aiming problem.

The confirmed Rocket Launcher method

The official Rocket Launcher page confirms that its explosions can destroy Crackstone. Fire so the rocket collides with a solid surface in the target area; the resulting explosion covers a wide, roughly circular area.

The Rocket Launcher starts with three rockets and reloads them automatically over time. Clear valuable resources or delicate factory structures away from the target before firing because the blast is not limited to one tile.

How to unlock the Rocket Launcher

The current Research page lists the Rocket Launcher in Tier 4 for 2,000 Gold. The Rocket Launcher page reports the same tier and cost.

If you encounter Crackstone before you own a suitable advanced digging tool, mark the location and return after further Research progression. Do not keep using the Shovel or Gun; the official Crackstone page explicitly rules out both.

Other advanced digging tools

The official Crackstone page says every digging tool other than the Shovel and Gun can destroy Crackstone. It does not provide a ranked comparison of speed, energy use, or collateral damage.

Use the Rocket Launcher when you want a method that is documented specifically for Crackstone. For another advanced digging tool, check its current description before choosing it for a tight factory layout.

Quick troubleshooting

  • Shovel does nothing: expected; it cannot affect Crackstone.
  • Gun does nothing: expected; it also cannot affect Crackstone.
  • You searched for stone or sandstone: verify that the in-game material is named Crackstone before applying this guide.
  • The rocket damages too much terrain: allow for its wide explosion area and move valuable materials or structures away first.
  • You cannot research the Rocket Launcher yet: continue Research progression until Tier 4 or use another confirmed digging tool you have unlocked.
