Refined concrete

Refined concrete is a placeable tile used as a paving material that creates a smooth, uniform ground surface. It is applied to the world as a tile and functions as a path-type terrain, changing the underlying ground where it is placed. Refined concrete is commonly used to create large paved areas for factories, railways, and vehicle roads because it visually and mechanically replaces other surface types where placed.

Refined concrete is placed using the game's tile-placement tools and can be removed by using the tile-removal tools while holding any kind of path item. The placement tool supports an adjustable placement area: the area in which refined concrete is placed can be increased and decreased by using the corresponding increase and decrease controls available for tile placement. When refined concrete is placed over a different kind of path tile, the previous path is automatically mined and removed, leaving the new refined concrete tile in its place.

Refined concrete interacts with other world systems as a standard tile: it occupies the ground layer, prevents placement of some entities that require bare ground, and can be painted over by other tiles when those are placed later. Because it is a path tile, it is treated as a path when held for removal or when using path-specific tools.

• Refined concrete is applied via the tile placement interface; the placement area can be adjusted with the placement tool's area controls.
• Removing refined concrete requires the tile removal tool while holding any path item.
• Placing refined concrete over another path automatically mines the underlying path and replaces it.
• Refined concrete occupies the tile layer and can be overwritten by subsequent tile placements.

Use refined concrete when you want a consistent surface across large sections of your base. Its automatic replacement behavior simplifies repaving: you can paint over existing path tiles and the previous path will be cleared without needing a separate mining step. Adjust the placement area to lay large uninterrupted sections or small patches as needed, and use the tile-removal function to clear refined concrete when redesigning factory layouts.
