What is a load-bearing wall?
A load-bearing wall is a wall perpendicular to the ground that, together with other walls of the same type, supports roofs and forms the foundation for upper floors . They are the main walls of any building and are characterized by being thicker than the other walls needed to construct it. The million-dollar question, given its importance, is whether a load-bearing wall can be demolished. To begin, let’s learn how to identify them.
How do I know if it’s a load-bearing wall?
The easiest way to determine if a wall is load-bearing is to consult the floor plan of your house . If you don’t know how to interpret it or don’t have it handy, there are still clues that can help you identify these walls in your home so you can plan your renovation. In any case, remember that with the deed to the house you should have been given a document showing the structure of the house and where a load-bearing wall can be clearly identified in the plans. If you don’t remember where you have the plans and you live in a building, you can ask the homeowners’ association for them.Characteristics of the load-bearing wall: how do you know if it is a load-bearing wall?
A load-bearing wall, also known as a load-bearing wall , has particular characteristics that allow it to be distinguished. One of these, which we have already mentioned, is its thickness, due to the fact that load-bearing walls are generally made of reinforced concrete . If you have had the opportunity to visit other homes in the building (in the case of an apartment), those walls that are the same in all of them and that do not change in thickness, are most likely load-bearing walls. Another thing that will quickly clarify whether a wall is load-bearing is whether it is possible to clearly see the support points when the structure is designed with a visible beam system. Finally, you can use your ear. If the sound when you tap the wall is hollow , it’s very likely not a load-bearing wall.
Before we start demolishing
Don’t make the mistake of starting a renovation and knocking down walls until you’re clear on which ones can be taken down. There are times when a wall separating two rooms turns out to be a load-bearing wall if other structures in the house have deteriorated over time and have begun to rely on it. The general advice is not to demolish a load-bearing wall, at least not without the assistance of qualified experts. Load-bearing walls can be demolished , but doing so requires replacing them with another structural element that performs the same function, as this is essential.You might be interested in: Interior design projects where glass is the star.
How to demolish a load-bearing wall
Normally, beams, either steel or wood, are used as a replacement. In other words, we can’t just knock down a load-bearing wall and put in a beam ; there always has to be a support point . When aiming for a more open space, it’s advantageous to have the option of reducing the size of these essential elements. By removing the cladding from the load-bearing wall, we can replace the load-bearing wall with a beam . Another popular idea is to demolish non-load-bearing walls and decorate the remaining load-bearing walls with natural stone such as marble. In fact, this idea can be applied to any part of the house. Your home may have one or more walls clad in natural stone. While they aren’t the cheapest option, there are very competitive prices available on the market today.Call an expert
