It is therefore necessary to call on a qualified professional for this type of work. There are many reasons that can lead you to break a load-bearing wall: opening a load-bearing wall for bay windows, opening a door or simply creating a window to gain brightness etc. Before embarking on the demolition of your load-bearing wall, several precautions are to follow for a successful project.
What is a load bearing wall?
This is a wall essential to every home. Its role is to prevent the infiltration of wind and rain but it also supports the rest of the house as the floor of the upper floor, the frame and the roof. The bearing wall stands out from a simple partition by the strength of the materials used and its thickness.
What are the formalities to follow?
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. Once the required authorizations, a certificate of feasibility of the project with an architect will be necessary. Indeed, an opening made in a hurry can call into question the solidity of the house.
Use a BET structure to break a bearing wall
Using the services of a structural BET or a BET demolition is an essential step in a project of felling a load-bearing wall. Indeed, only seasoned professionals at office strip out Melbourne can advise you on the feasibility and consequences of your project. The role of a BET structure worthy of the name is to indicate to you, thanks to a calculation of very precise structure, which elements of support will come to replace the lift of the part of the demolished wall. The technical design office will also guide you on the procedure of opening or removing the load-bearing wall. If necessary, he will accompany you in the demolition procedure to ensure that everything is done according to the rules of art.
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.
