The bearing wall stands out from a simple partition by the strength of the materials used and its thickness.

In the context of a co-ownership, it is necessary to obtain the authorization of the Trustee before opening or cutting down a load-bearing wall. If you own a detached house, no authorization is required but it is recommended to get closer to your town hall to find out if a permit to demolish or a building permit is necessary.

The opening of the bearing wall

In order to bring down the wall, it is important to secure and ensure that the structure of the home does not move or collapse. For this, it is necessary to support the wall with bastaings (they are solid wooden beams that will serve to consolidate the house during the opening of the wall) or an IPN (it is this times a steel beam) and metal props. This step then makes it possible to install a reinforced concrete lintel which, once installed and sealed, will distribute the weight of the structure on the remaining parts of the load-bearing wall.

It only remains to drop the wall to get the desired opening. For this, it is possible to use a chainsaw to obtain the contours of the opening, which will then demolish the wall to ground. Once the opening completely cleared, it is sufficient to form the lintel and melt in the rest of the house.

Here are the different basic steps to follow when opening a load bearing wall:

  • Lay a lintel: The lintel is a metal beam designed to support the considerable weight of the upper floors to the load-bearing wall. The dimensions of the lintel are determined by the calculation notes established by the BET structure. After installing the lintel IPN, the company will form it with concrete.
  • Drill a bearing wall: To break a load-bearing wall – or put it down, in the building language – the company will use a mass or a grinder. For a neat finish, request the use of a grinder for the contours of the wall.
  • Lay props: The props are metal pieces of vertical frame to support the wall or the lintel. These props will prevent the fall of the floor during the duration of the work. Insist that the masonry company place shims made of wood or rubber to preserve your floor covering.
