JES has 3 different types of Pier Systems that all serve to support your foundation from below: the Helical Pier System, the Push Pier System, and the Slab Pier System. The Helical Pier System pushes against your foundation structure from below the ground, providing strong, long lasting support. The Push Pier System is optimal for homeowners that are unaware of the soil conditions below their foundation, however, it functions in more or less the same way that the Helical Pier System does. The Slab Pier System works doubly to repair your foundation and lift your concrete all at once.

For foundation wall repairs, there are 2 possible options to choose from: the Carbon Fiber Wall Reinforcing System and the IntelliBrace™ Wall Repair System. The Carbon Fiber Wall Reinforcing System utilizes a polymer-reinforced fiber that is 10 times stronger than steel, therefore, preventing bowed in foundation walls from becoming worse. There is also no external excavation needed to install the Carbon Fiber Wall, so installation is quick and clean. The IntelliBrace™ Wall Repair System is a more permanent solution and is able to both correct bowed walls and straighten them back into place over time. Although there is no external excavation necessary, installation does require that contractors attach steel I-beams to your wall.

For homeowners interested in repairing sunken foundation floors, the IntelliJack™ Floor Stabilization is the perfect solution! The IntelliJack™ support jacks are constructed from galvanized steel, a rust and corrosion resistant metal. This way, your foundation floors can be supported for a long period of time without worrying about future damage or problems. It is also capable of supporting total weights up to 24,000 pounds per support jack. Homeowners no longer have to worry about uneven or sunken foundation floors or walls ever again.

A pervasive and persistent odor around your home can be very frustrating when you do not know where it comes from, especially if a deep clean and thorough airing of your home does not remove it. The nature of the smell in your basement or wider home can even help you to figure out what the most likely cause is (and the concentration of the smell can help you to pinpoint hotspots).

If the smell in your home is largely musty in nature, then it is most likely being caused by dampness and the formation of fungi like mold and wood rot. This smell is likely to get worse when you are in close proximity with large formations, and may also cause symptoms similar to those caused by hay fever and other mild allergies. You will recognize mold and fungal growths in your home primarily by discoloration and changes in the texture of affected organic materials like wood or textiles.

If the smell has a more vinegary edge, however, then it is most likely to be a form of pest infestation. Most specifically, vinegary smells are associated with cockroach infestations. If, however, the odor in your home smells of ammonia, then it is more likely to be the result of a rodent infestation in your home. If the cause of the unpleasant smell in your home is infestation, you are likely to see other signs. For example, you may see things like droppings, nest formations, and of course, the pests themselves.

Crawl space vents are fairly common in Northeast NC and were installed in homes that were built between 1950 and 1990 as a matter of best practice. This was done because industry specialists believed that crawl space ventilation would prevent dampness and humidity in a property by increasing airflow. Of course, later studies found that such vents do in fact increase airflow. Unfortunately, it is not a good thing.

The increased airflow has two main effects on a home. Firstly, it contributes to something called the stack effect. The stack effect, also called the chimney effect, is a process by which a channel of air runs from the bottom of a property to the top. This can cause issues in any home, and will be most pronounced in mid-summer and winter when your HVAC system is in full use. The stack effect is fueled by how air reacts to being heated or cooled. Since artificially-processed air rises or sinks, it will exit your home and draw in air from outside.

This causes a number of issues, the foremost being high relative humidity. The summers in Northeast NC can be muggy and humid, anyway, so keeping a property’s interior relatively arid can be a challenge. In a home that has exposed crawl space vents, it is almost impossible. Dampness, of course, has a number of negative side effects, including the increased risk of wood rot and mold formation. So, all in all, it is best to cover your vents where possible.

If your concrete is flaking off, it’s a sign that something is wrong with the concrete. Concrete doesn’t stay smooth forever, and some flaking is to be expected after a few years. However, you should inform yourself on the kind of flaking it is so that you can get a better understanding of what your concrete is going through and how it could potentially lead to settling.

There are two types of surface deterioration concrete structures go through: pitting and flaking. They are caused by different things though are very similar in terms of appearance. Pay close attention when inspecting your concrete, and you’ll be able to differentiate between the two.

  • Concrete Pitting 

Concrete pitting is caused by problems with the way the concrete was produced or poured. It’s a problem that only shows up after the concrete has finished curing. Concrete pitting means there’s a problem with the structural integrity of the concrete itself. It indicates that the concrete is weak and deteriorates incredibly easily, which means that you have to be careful if you see signs of pitting on a settled slab.

Concrete pitting is defined by small craters that form on the concrete structure. Although the craters are only visible on the surface, if you were to break the slab open, you would see that the craters run deep since the entire concrete is deteriorating. The craters can either appear sporadically across the concrete or, they can clump up and form one big crater that makes it look as if a piece of the concrete has broken off.

  • Concrete Flaking 

Concrete flaking is caused by an external force eroding the surface of the concrete. Freeze-thaw damage is a common cause of flaking since the ice creates micro-tears across the surface of the slab. If the micro-tears become too much, the piece will flake off. Concrete flaking can still happen on slabs that are strong, so it does not indicate that there was a problem with its production. You can tell it’s flaking and not pitting when a big chunk flakes off and you don’t see any craters, indicating that the damage was only surface-level.

Just because flaking can occur on slabs that are strong does not mean it doesn’t affect settling. By deteriorating the surface of the slab, it allows water to seep through to the soil a lot easier, accelerating settling. Plus, a flaking slab does not stay strong for long. As the surface breaks apart, the slab loses its soundness and is likely to break once it begins settling.
