A joint section is a section of construction that contains a joint, often in place to allow for some movement to occur without breakage. In the construction and design of large buildings, particularly those made primarily of concrete, section joints are put in place to allow for a bit of movement when the building settles. Theses joints are put in throughout many locations in the foundation of these buildings and are carefully placed in order to handle the brunt of movement. These instances allow for the building to remain standing even if there is an earthquake or shifting of some other kind that could cause cracking.
Having a section joint put in place in your basement is something that could provide more security for your building. Expansion joints or section joints might need to be put in place in your building if there is a great deal of settling in the building. A contractor might also put them in when building your new home if it is on the side of a slant on a hill or sloping section of your property. When designing a structure the use of section joints can provide the building with extra give when it is necessary, protecting the building from potential harm, foundation cracking and damage.
