This mod makes belts and machines only placable on flooring that provides more than 100% walking speed, such as stone bricks and concrete.
Currently anything that can be placed and uses energy (electricity or fuel) as well as belts and splitters are affected.
To get started you can place wood as a tile. The graphics for the wooden tile were stolen from More_Floors.
Known issue:
Removing the flooring under a machine deletes the machine (the player does not get the item back).
