Renovating

Why walls are torn

It often happens when a new building is relocated. But even if the former builder family still lives in the building, it happens. There is talk of the need to tear down a wall. This usually happens for two reasons:

to increase living space or a room

  • to set a door or a window
  • load-bearing or non-load-bearing walls - a weighty question

Regardless of the project, statics must first be taken into account. Interior walls can be constructed to be load-bearing or non-load-bearing. Load-bearing inside walls divert the weight of the building, so they can not and should not be torn.

In most cases, whether it is a load-bearing or non-load-bearing wall, a structural engineer or an architect must clarify it. A first clue may provide the roof truss. A purlin roof derives the weight to the outside over the Drempel (knee skirt or ring beam), while the purlin roof within the floor plan has carriers that derive directly down, so here need supporting walls.

Breaking through the walls of the door

If a wall is not to be completely torn down, but only a door or window opening can be made, it may be possible to do this on a load-bearing wall up to a certain width. For this purpose, a concrete fall is installed. This should necessarily and necessarily be accompanied by a structural engineer or architect.

Installations in the wall

Once the static questions have been clarified, you still can not tear off the wall. Now the focus is first on the installations in the wall. As a rule, these are the following installations:

Water installation

  • Electricity installation
  • Now it is important to clarify in advance whether the installations were merely routed to this wall and ended here, or whether, in principle, it is only a section of the house installation, the Here only in other areas of the house is continued. In the latter case, you must first find a solution to "redirect" these installations.

Bear in mind that electrical installations in particular must be carried out by a suitably certified specialist company. Should only this wall be supplied with electricity and / or water, this area can be separated and made blind or be redirected to other walls.

Preparatory work before tearing the wall

Now, there are more preparatory work to be done. So you should order the required rubble container in any case in advance. Otherwise, you have to move the rubble twice. Do not underestimate the amount of building rubble.

Immediately before the demolition work, all rooms are covered in a dust-proof way. Otherwise, you will be left with dust for months after being torn off.

Tearing the wall

If power and water are adjusted during tearing, do not forget to turn off both. The easiest way is to first remove the plaster with a miter and a chisel up to a drills and a chisel in a medium-sized area. The idea behind this is that you can now cut out individual stones along the joints (mortar or glue). Then the wall in this area is so unstable that the large-scale knocking out is easier. Immediately after demolition, the lintel must be installed.

Tips & TricksWalls made of porous or aerated concrete can also be torn off using a stone or concrete mill. These walls literally cut like butter and greatly simplify tearing.
