Foundational Cracks San Bernardino, California
Cracks In The Foundation Can Cause Serious Problems
Cracks in foundations: when to worry, causes, and how to fix Cracks can mean serious structural concerns and some may be quite minor. Cracks in foundations are caused by soil movement that is accompanied by the expansion and contraction of the soil. Soils with a coarse clay content can cause a foundation to have a movement of up to 40 percent, while those with a light clay content can have movement of up to 60 percent. Foundation cracks can also be caused by soil shifting. The most critical times for foundation cracks are at the end of the year and at the beginning of the rainy season since rainy weather is one of the biggest culprits in foundation failure.
Most people tend to believe that cracked and missing foundation tiles are symptoms of structural foundation damage. The truth is that cracking indicates a more serious problem, which means that you should get professionals out to the site as soon as possible. Foundation cracks can also be a symptom of other issues in your home, so it is important to see an experienced engineer to evaluate the situation. There are several signs to look out for when it comes to horizontal foundation blocks San Bernardino, CA
Cracks at the bottom of foundation walls:
horizontal cracks are common around doors and windows in the house. If you find cracks in the corners of your door or window frame, then there could be an issue with the structural integrity of your floor or wall. This includes concrete slabs that have been poured too close together. If you see vertical cracks on the outside of the home, then this is a sign of structural moisture damage, as well as settling. The only way to repair these cracks is to remove the concrete slabs and replace them with new ones.
Cracks at the top of foundation walls:
this is the most obvious sign and will usually indicate that structural maintenance or replacement work needs to be done. The main cause behind this type of crack is poor construction practice. For example, improperly set piers or timbers can easily cause cracks to widen over time. Other causes can include poor waterproofing practices, such as failing to apply a suitable sealant. You may need to call in a contractor to properly fix these types of foundation repairs.
Cracks at the corners of rooms:
these are often caused by improper floor framing practices, such as over-inch in wall depth. Also, poorly insulated or poorly placed windows and doors can also cause these types of foundation issues. These cracks often appear as tiny pits that have formed due to water pressure. In most cases, these cracks can be fixed with a few simple repairs.
these are commonly found in older houses and are usually caused by insufficiently dried mortar joints. Stair-step cracks can cause a creaking noise, which can be annoying for the residents. To make matters worse, these cracks can grow deeper with time, which makes the situation even worse. In many cases, stair-steeple cracks can be fixed using silicone caulk, or a simple mixture of sand and pumice.
Foundation cracks may also be caused by soils that are not set correctly. A proper subsurface drainage system is important for all types of foundations, as excess moisture causes soil to expand, which can eventually lead to foundation failure. If the foundations are built on wet soils, it is important to add a layer of gravel along with topsoil, to ensure that excess moisture is drained away from the foundation. This can be done with the help of a pump or excavator.
When dealing with soil problems, hiring a structural engineer to inspect and evaluate the problem is the best way to determine what repairs are needed. Structural engineers are trained to detect any signs of damage, and then make recommendations for repairs. Many times, they will be able to perform the repairs without actually causing structural damage to the foundation. With proper inspections and repairs, many problems can be avoided, saving you money and time in the long run. if you are having problems with your home, make sure to contact foundation repair companies near me.
