Concrete Blocks are a craftable building material that is very durable. Zombies can still break it, but it will take a lot of time since it is one of the stronger building materials in the game. Hitting the block will yield 25 Cobblestone Rocks in total. All Concrete Blocks have the same stats.
Block Varieties
The Concrete Blocks comes in a number of different varieties, each with the same durability and features. The only difference is the shape and hit boxes, which may allow you to shoot through them or walk up them. There are rare cases, when a variety has different properties, see Notes below for specific information.

Schematic
It is important to note that concrete - when initially upgraded - will be wet and therefore significantly weaker than dry concrete, giving less structural integrity and a lower durability until it eventually dries (over the course of roughly a day). For this reason, temporary supports need to be added when making higher level floors.
