Reinforcement
Reinforcement, a NeoForge mod for 1.21.1, adds blast-resistant versions of common building blocks for players who want sturdy walls, doors and windows.
What it does
The mod adds reinforced blocks inspired by the blast-proof blocks of HBM's Nuclear Tech mod. Reinforced Concrete, Reinforced Stone Bricks, Reinforced Glowstone, Reinforced Glass and Reinforced Tinted Glass are placeable blocks, and the concrete and stone brick variants also come as stairs and slabs. Reinforced Iron Door, Reinforced Iron Trapdoor and Reinforced Iron Pressure Plate cover the door, trapdoor and plate roles.
Reinforcement runs on client and server, so the server and every player need it. Connected textures work through Continuity support. Files are published for NeoForge only, for 1.21.1 alone, and the source code and issue tracker are public under the MIT License, which makes the mod open source.
Key features
Reinforced building blocks
Concrete, stone bricks, glowstone, glass and tinted glass each get a reinforced counterpart for walls and floors.
Reinforced stairs and slabs
Reinforced Concrete and Reinforced Stone Bricks include stair and slab variants that match their full blocks.
Reinforced iron doors and plates
Reinforced Iron Door, Reinforced Iron Trapdoor and Reinforced Iron Pressure Plate give iron-style entrances and triggers a reinforced option.
Connected textures
Continuity support lets the reinforced glass and tinted glass blocks join smoothly with neighboring blocks.

Use cases
Sturdy bases
Walls, floors and entrances built from reinforced blocks hold up better against explosions than their plain versions.
Who it’s for: Builders who want blast-resistant decoration, and server owners who run Forge-style base-building or raid-themed content on NeoForge 1.21.1.
How it compares
Doors On Stairs! is a server-side only NeoForge mod for 1.21.1, under All rights reserved and not open source, so it adds nothing on the client. HBM's Nuclear Tech Unofficial NeoForge Edition also targets NeoForge 1.21.1 with client and server installs, but it is open source under the GNU Lesser General Public License v3.0 or later and covers a far larger set of content. Easy Doors & Trapdoors uses the MIT License and runs on Fabric, Forge, NeoForge and Quilt for 1.21 – 1.21.11, with the server required and the client optional.
