Shoring is a temporary structure used to keep the main under-construction structure from collapsing. The most prevalent sort of shoring support is required during the excavation stage of construction. After this has been completed, other methods can be used. The goal of shoring is to provide support for the main structure while work on it is being done. This may include supporting walls that are being built up, floor joists which are being laid down, or any other structure that needs to be kept stable while work is being done on another part of the building. There are two basic types of shoring: temporary and permanent. Temporary shoring is usually erected during the early stages of construction when the site is still owned by someone else. It is usually brought in by truck and placed in the appropriate location. Once the area has been excavated to the desired depth, the shoring is removed and replaced with footings or other forms of permanent foundation material. Permanent shoring is used to protect an existing building on a construction site. It is usually installed by a professional shoring company that specializes in this kind of work. Permanent shoring allows for faster construction since it does not have to be set up before each use. Poles or posts with boards attached to them are used to build shoring.
