The Materials include walls and flooring. Since version The Slammer, Materials can be accessed from two in-game menus: Flooring and Walls & Doors (Walls tab).

Installation & Removal

  • To install walls or floors: Select a wall or floor type from the Materials menu, click and drag over the desired area and a job for your Workmen is created.
  • To remove walls: select the "Demolish Walls" tool in the materials menu and select the walls you want to remove. This will task the Workmen with removing the selected wall or wall section.
  • To remove floors: replace them by another flooring (e.g. by Concrete Floor or Dirt, the default floors indoors and outdoors).
  • To remove everything inside a building: select the "Clean Indoor Area" tool in the materials menu and select the area you want to clear. All indoor walls, objects, floors and room assignments will be removed, with the Foundation and Utilities being kept.
  • To remove entire buildings: select the "Bulldoze" tool in the Foundations menu and select the foundation to be removed. The complete building, with the Foundation, all indoor walls, objects, floors, room assignments, cables and water pipes will be removed, with some rubble and garbage left.


Walls are used to enclose rooms, and to secure the perimeter of your prison. Brick Walls and Concrete Walls differ only in aesthetics, the Fence is built faster and is much cheaper, the Perimeter Wall, while being very expensive, will slow down the digging of Escape Tunnels more.

The Walls from the Materials section are not sufficient to construct buildings. Use Foundations for that (see Walls and foundations for a detailed explanation of the differences).

Flooring can either be used indoors, outdoors, or in the case of Concrete Tiles, both indoor and outdoor.

Flooring has different movement speeds:

  • Slow (Factor < 1.0, mostly 0.7 or 0.5)
  • Normal (Factor 1.0)
  • Fast (Factor > 1.0, mostly 1.2-1.3)

This can be utilised to either reduce walking times within your prison, or to slow down prisoners where appropriate.

Other than the above attributes, floors differ mainly in aesthetics and price, ranging from free (Sand and Dirt, both slow) to $50 per square (Wooden Floor and Ceramic Floor, both normal speed).

Tips & Other Information

  • Currently, prisoners will not attempt to escape by breaking through walls or fences.
  • Your Staff can work more efficiently if directed through routes floored with tiles that have "fast" speed.
