Floors

Floors are a type of constructions which cover the natural terrain with an artificial surface, and allow other constructions to be built on top of them.

Effects

Constructed floors can bring benefits such as increased movement speed, beauty, and cleanliness, as well as preventing wild plants from growing and fire from spreading.

Movement speed

Natural soil allows the growth of vegetation such as tall grass, bushes, and brambles, all of which cause a walking speed reduction for Colonists. Trees prevent movement altogether, and also prevent roofs from being built over them. Other natural surfaces incapable of growing vegetation such as raw stone, sand or ice also have lower movement speeds. Flooring a frequent path will reduce the time required to walk between the two areas.

Beauty of room

Colonists are affected in mood according to their surroundings, especially those locations where they spend most of the day or night such as a bedroom, kitchen, workshop, research lab, etc. Carpets for instance can make bedrooms look nicer for their occupants.

Sanitation / Safety

Flooring is an important factor when calculating a room's Cleanliness, which is important for most rooms but particularly for kitchens, hospitals and laboratories.

Tiles with a cleanliness bonus bring better success rates in hospitalized quarters as they help prevent the posssibility of infection. Non-flammable flooring helps prevent fire advance to its tile while also protecting underground electrical conducts damage by weather.

No plant growth

Any flooring placed outdoors will prevent grass, bushes or trees from spreading there. This can be useful to keep any trees from growing in the path of a wind turbine and reducing its power output. Surrounding fields with flooring will prevent trees growing there, which your growers must clear first before they sow nearby. It can also be used to create fire breaks to keep wildfires from spreading to your base if non-flammable materials were used.

Flooring can even help with security in certain biomes. While giving a movement bonus to raiders, covering your killbox in flooring will prevent any trees growing there for raiders to take cover behind.

Removing Floors

Floors can be removed with the Remove floor order, which is found under the Architect/Floors tab. After floors are removed, the tile will retain its old terrain type.

Most (but not all^(which?)) floors types return back, on average, half of the resources spent at construction, which can be useful when raiding settlements or temporary camps.

Types of Flooring

There are several different types of flooring available, with each requiring specific resources to construct each tile.
