Dig in. GroundWorks is standalone excavation and construction with vanilla tools: dig outdoors or beneath existing houses, preview and frame preset trenches, moats and basements, and build safe underground spaces.

Dig anywhere sensible

Excavate outdoors or beneath existing houses using vanilla tools and materials.

10 presets, 4 directions

Preview and frame preset trenches, moats and basements. Materials and time scale with the footprint.

Framing and collapse

Intact framing prevents collapse, so secure what you dig.

Go deeper

Generate deeper floors and walls, backfill, and build routes.

Equipment APIs

Optional equipment integration, including CAT Construction.

Enhanced visibility

An optional FJL companion adds local cutaways and keeps the nearby surface visible while underground. Toggle it in Sandbox Options.

What's new in 0.15.3

Build 42.22 (0.15.3) — the optional cavity-visibility companion keeps working on Project Zomboid 42.22 as well as 42.21 and 42.20.4. Lua excavation is unchanged.
Update together — update Faded Java Loader to 0.6.9 in the same refresh and fully restart Project Zomboid.

Requirements

Project Zomboid Build 42.20.3+ (also 42.21 and 42.22). No required dependencies; all gameplay works through Lua alone. Enhanced rendering needs Faded Java Loader 0.3.4+ on PZ 42.20.4, 42.21 or 42.22. Foreground structures, lighting and extreme depth can still affect visibility.
