OVERVIEW
Hey Survivors! Are you tired of magical zombie fingernails slicing through your concrete base like butter? Why not try building with Ultra-High Performance Concrete!
UHPC is used IRL for heavy-duty construction on things like bridges and highway infrastructure. It has more than double the tensile strength of traditional concrete and can absorb up to 30,000 psi of compression without fracturing - which makes it perfect for building a late-game horde base, a player jail, or anything else you want to outlast the apocalypse.
FEATURES
This mod adds an entirely new building material, which can be crafted as block shapes or you can upgrade steel structures using the UHPC power drill. The drill is a modified impact driver that behaves like a kind of advanced nail-gun and is the only tool capable of installing UHPC - other repair tools can fix the blocks but can't upgrade them.
Crafting UHPC blocks also requires higher-tier items like a crucible for making rebar at the forge or acid to make the mortar at the chemistry station. This mod treats UHPC as an end-game material and it is purposefully difficult to obtain.




Each block of UHPC has 30,000 HP and can be repaired rapidly with the power drill. The UHPC material has also been added to the game's paint library and can be applied using the paintbrush.
INSTALLATION
As this mod adds a new material, OCB Custom Textures Core Mod (V2.0) is required. UHPC has been updated for game version 2.0 - it works on older versions if the appropriate version of Ocb's texture modlet is installed but 2.0 is recommended. EAC should also be disabled.
Installing UHPC is the same as any other mod. Download and unzip the folder, then add it to the Mods folder in your game directory. The 'z_' prefix has been added to the UHPC mod folder to ensure it loads after Ocb's mod.
