Better Slabs

Better Slabs is a Fabric mod for Minecraft 26.2 that lets you combine two different slab types into a single full block. The bottom half and the top half can use different materials (for example brick on top and smooth stone on the bottom), so you get a true mixed double slab in one block space instead of being limited to two halves of the same slab.

Purpose

The mod expands building options: any ordered pair of distinct slabs from the mod’s supported list becomes its own block. That gives on the order of 9,900 different combo blocks (each pair is directional: bottom slab A + top slab B is not the same as A on top and B on the bottom). The list includes vanilla slabs (pale oak, plus sulfur and cinnabar slabs from Minecraft 26.2) and Moar Concrete Unofficial concrete slabs and concrete brick slabs.

How it works

There are no crafting recipes for these combo blocks. You create them in the world:

• Place or find a slab (bottom or top half).
• Hold a different slab item from the supported list and use it on the correct face: the top face of a bottom slab to add the second half on top, or the bottom face of a top slab to add a half from below.
• You can also complete the empty half by clicking an adjacent block in a way that would normally place a slab into that half (same idea as vanilla slab placement).
• The mod only combines slabs that appear on its internal list; you cannot pair a slab with itself.

In creative mode, all combo blocks are listed in a dedicated Double slabs tab. There is a small easter-egg block at the end of that tab.

Breaking blocks

In survival, breaking a combo block removes only the half you are targeting. The other half stays as a normal slab. Drops and tool rules match that slab type. Mining speed depends on the half you are breaking. In creative mode, the whole combo breaks at once like a normal block.

Requirements

• Minecraft 26.2
• Fabric Loader and Fabric API
• Moar Concrete Unofficial (https://modrinth.com/mod/moar-concrete-unofficial — mod id remains moarconcrete)
• Java 25 or newer

For multiplayer, the mod must be installed on the server and on clients that join that world.
