How to make an opening in the walls

To expand the space in the house, many people make a redevelopment, which involves the construction of additional walls and the dismantling of the walls to create openings. When dismantling the walls, it is necessary to take into account the presence and location of the load -bearing and unnecessary walls. According to the law, it is impossible to redevelop the carrier walls. Before starting redevelopment, it is necessary to coordinate the project with the housing inspection in order not to endanger the building. When arranging the opening, first they install jumpers that will take on a certain part of the load. To do this, make the marking of the opening, as well as indicate the places where the jumpers will be installed. Then, holes are made in the corners to form the working points. A niche is made with a hammer and a chisel and holes are drilled to install jumpers. The jumpers themselves should be of good quality, as they will affect the safety of the structure. After, fill the niche under the channel cement. Then, install a channel and tighten it with bolts. The opening is cut through using a diamond type of cutting and the mesh is pulled to the surface. In the end, the opening is finished with plaster.
