When a structure gets damaged, such as a brick wall being broken by a large tree branch or even a broken down sidewalk due to ice and snow, the first thing most people call on our contractors and companies that provide a concrete foundation repair. There are many reasons why it is necessary to have a foundation that is solid and secure, including the fact that you do not want your home to be destroyed from storms or from water damage. Concrete foundations are also better than block built structures simply because they don’t harbor moisture and are far more durable. While block is typically made out of cement, the blocks that comprise a concrete foundation are actually made from clay.
Cracking can occur due to a lot of different things, such as excess weight sitting on the foundation, age of the structure, poor drainage and so forth. Unfortunately, some older homes and structures may contain more issues than others which lead to cracks in their concrete foundations. Age and weathering can also accelerate cracking. A small crack in a slab’s foundation can easily expand to an entire wall of water. This happens when excess pressure forces a slab’s corners to expand outward, which then causes large amounts of water to build up in the interior of the foundation.
The best way to avoid any problems with a slab-on-grade foundation is to build your home at least six feet away from the house’s center line. If you are building a new home, make sure you check the city building codes to see what the maximum foundation length is for your home. Also, keep in mind that you should only use a slab-on-grade concrete foundation, as blocks will float and flex, which can result in foundation movement. The best solution is to build a six-foot wall, which is still two feet deeper than the exterior of the house.
There are three types of concrete foundations, all of which have varying degrees of movement. These three types of foundations include post-holes, slab-on-grade foundations and slab-on-abutting foundations. Post-holes are holes left in the soil from a previous excavation. They are not usually the primary foundation.
Slab-on-abutting foundations are set up with slabs of Styrofoam, lumber or plywood placed above the soil in a pit. A layer of rebar is then poured into the bottom of the pit. This gives the final foundation an adequately level surface. Precast concrete forms are the most commonly used foundation type. Precast concrete forms are reinforced concrete forms that are poured in place after they have been shaped like a slab.
The most modern concrete foundations are poured on a machine that makes use of computerized technology. In addition to being precise, they also take away a lot of manual labor. Many of today’s concrete walls have automatic controls that make pouring easier than it has ever been. When you have a foundation that is properly poured it will ensure that your building is structurally sound.
