Remove an inner wall


Especially in older existing buildings, the individual rooms are usually small. It is close to the idea of ​​enlarging rooms by removing an inner wall. Here you can read what to look for and how to proceed if you want to remove an interior wall.

Over time, requirements for premises are changing

The layout of rooms in a new building is planned largely according to the requirements of the client. But these requirements can change significantly over time. Be it through family growth, children move out or a building has new owners.

How was an interior wall made?

Many houses are a compromise between construction costs and requirements in terms of room size. Therefore, there are quite a few smaller rooms in buildings, especially in existing buildings. The idea is obvious, simply by removing an inner wall from two small to create a large room. But even here a first distinction is necessary before:

  • Interior wall (in wet construction)
  • Interior wall made of drywall (drywall)

The removal of a drywall is relatively quick and easy to accomplish. More information can be found in the linked guidebook.

Statics: load-bearing or non-load-bearing interior wall

With a bricked interior wall, you can not easily lay hands on it. For masonry interior walls can be load-bearing or non-load-bearing walls. A first clue to this can be provided by the existing roof truss.

The roof truss is made either as a purlin roof or rafter roof (or a form of it like the Kehlbalkendach). The rafter roof derives the weight over the outer walls, the purlin roof on abutment pillars within the building footprint. Ultimately, however, a structural analyst should be interviewed so that it can be ruled out to remove a load-bearing wall.

Prepare building services and switch off

Once these points have been clarified, the existing building services must be prepared. Preferably, current and / or water should be turned off in existing lines and / or pipes. In particular, in the presence of plumbing installations, they require corresponding components for sealing the pipes (blanking plugs, for example). Electrical cables are dismantled and then brought together in a junction box.

Direct preparation for removing the inner wall

Now the actual demolition of the inner wall can almost begin. You still need large plastic tarpaulins to protect any furniture or other spaces against the significant dust. If you do not want to move the rubble twice (out of the house and then into the container), you may also have to order a building rubbish container in advance. To ensure that the building rubbish container is correctly dimensioned, you can calculate the building rubble density in advance.

The removal or the demolition of the inner wall

Now begins the removal of the inner wall. You need a miter with appropriate stone chisels, a sledgehammer and possibly a percussion drill with chisel attachments. With the miter and chisel, an area is cut off so far that they recognize the wall structure (where are bricks in the mortar bed).

First, you can then simply knock out some bricks with the chisel in mortar bed. Now, the inner wall is already so far that you can start the big sledgehammer. Beat the inner wall until just past the connection walls. The "fine work" then perform again with a hammer and chisel.

Tips & Tricks

If you only want to remove a part of the inner wall, for example, to install a door, you still need to get the required lintel, which should be used as soon as possible. How to install a concrete fall, you can read here.
