Load-bearing walls are structural elements in a building that support the weight of the roof, floors, and any additional loads above them. These walls transfer the weight down to the foundation, ensuring the stability and integrity of the structure. They are typically made of materials like concrete, brick, or wood and are strategically placed throughout the building. In contrast to non-load-bearing walls, which only serve to divide spaces, load-bearing walls are essential for maintaining the overall strength of a building. When renovating or altering a structure, it is crucial to identify these walls to avoid compromising the building's safety and stability.
