When it comes to foundation jacks, understanding their role in maintaining the structural integrity of buildings is paramount. From preventing cracks to ensuring even weight distribution, these devices are crucial in the construction industry.

But what about the different types of foundation jacks available and how they are installed? And most importantly, how do you determine which one is the best fit for your specific foundation repair needs?

Above All Foundation Repair is here to answer these essential questions and more in our detailed exploration of foundation jacks.

What is a Foundation Jack?

Foundation jacks are essential structural devices used to support and stabilize the foundations of buildings. When a foundation needs extra support, foundation jacks come to the rescue.

These temporary supports are commonly used during construction to ensure that the foundation remains level and stable. They’re particularly handy when working on a pier and beam or crawl space foundation. However, they could also be used in undertunneling methods for repairing a slab foundation, providing the necessary reinforcement to keep everything in place.

During construction, foundation jacks play a crucial role in ensuring that the weight distribution is even across the entire foundation. By using these jacks, construction workers can make precise adjustments to level the foundation or use them as temporary supports to later install permanent solutions in some homes, like helical piers and push piers, that ultimately lead to a well-built and structurally sound building.

Whether it’s a small residential project or a large commercial development, foundation jacks are a key tool in the construction industry.

Why Foundations Typically Need Repairs

Frequent exposure to moisture and soil movement can often lead to the need for foundation repairs, but several issues, in general, can make you call experts like those at Above All Foundation Repair.

Remember that soil isn’t just dirt or gravel, as it’s composed of both organic and inorganic material and has several degrees of humidity in it. There are different soil types made up of different types of rock and minerals, and some of them expand and contract severely depending on weather conditions, moisture, seismic activity, and what is above it. 

This can cause problems like expansive soil, swelling and shrinking with the seasons, or because of water seeping into it. You can be facing foundation settlement, sloping floors, wall cracks, mold, and worse, structural danger. 

Another issue is the wood posts or concrete beams that make up the foundation. They made have too much wear and tear to be able to properly hold onto your home. Coupled with problems like soil erosion or tree roots growing under, then you need foundation specialists to come in quickly. 

So, foundations, although strong, can face challenges that may require maintenance to ensure the stability of your home. 

Foundation jacks come in and help foundation specialists inspect and repair whatever foundation damage is putting your home and livelihood in danger, be it settlement or failures in pier and beam installations. The jacks will help put the foundation back to its original position or reinforce it to prevent future structural damage.

Most Common Type of Foundation That Needs Jacks

If you notice cracks in your walls, sloping floors, or doors that stick, you might need foundation jacks.

But that also depends on the type of foundation you have. Most of the time, jacks are used for foundations with crawl spaces, meaning most pier and beam foundations. These foundations are basically small gaps underneath homes that allow access to plumbing and electrical systems, with the home being lifted above the soil by wooden posts or rebar and concrete blocks or beams driven into the soil.

The pier and beams are connected all the way to the competent, load-bearing soil (bedrock) beneath the property, or at least until the beams reach stable soil conditions. 

Some concrete slab foundation repairs can also need jacks in cases where tunneling is being used to fix the concrete or where the home has a mix of both concrete slab and pier and beam foundations, like those with basement foundations. But this is rarer.

When these foundations need repair, you get crawl space jacks or movable jack posts that foundation repair contractors will use to level the building and prepare for foundation repairs.

Signs You Might Need Foundation Jacks

Look for the following indicators of foundation or crawl space issues that can be fixed with jacks: 

  • You have sagging or uneven floors.  
  • Soft or even spongy floors beneath your feet. 
  • Noisy and creaky floors. 
  • Cracks in walls. 
  • Basement walls are cracked, slanted, or sinking.
  • Doors that won’t close properly.
  • Visible haps between walls, ceilings, or floors.
  • Walking past furniture makes it sway more.
  • The crawl space foundation baseboards have mold on them.
  • The home smells musty.
  • The floor above the crawl space is uneven or deformed.
  • Constant presence of pests. 

Any of these signs, from uneven floors to baseboards with mold, are worth contacting a foundation repair specialist right away.

What Most Jacks Are Made Of

Most jacks are typically made of durable steel or aluminum for strength and stability. When it comes to foundation jacks, the material they’re crafted from plays a crucial role in providing the necessary support for your type of foundation. Steel jacks are known for their robustness and are often chosen for their ability to withstand heavy loads, making them ideal for offering permanent solutions to foundation issues.

On the other hand, aluminum jacks are lightweight yet sturdy, making them easier to handle and install in various forms of buildings.

Choosing the right material for your foundation jack is essential in ensuring the stability and longevity of your building’s structure. Whether you have a concrete slab foundation or a pier and beam foundation, selecting a jack made of steel or aluminum can provide the necessary reinforcement needed to address any underlying issues.

Type of Foundation Jacks

To address various types of foundation repairs, utilizing different jacks is essential for providing adequate support and stabilization. When it comes to foundation repair, having the right type of jack can make a significant difference in the outcome.

In foundation repair jobs, there are several types of foundation jacks commonly used, including:

  • Hydraulic Jacks: These jacks use hydraulic power to lift and support the foundation. They are versatile and can handle heavy loads. Hydraulic jacks are commonly used in various foundation repair applications.
  • Screw Jacks: Screw jacks are mechanical devices that use a threaded rod to lift or support the foundation. They are versatile and typically used in situations where precise adjustments are needed, like in leveling, but are controlled by hand.
  • Bottle Jacks: Bottle jacks are compact and portable jacks that use hydraulic cylinders to lift heavy loads. Bottle jacks are commonly used in quick foundation repair jobs due to their ease of use and efficiency, especially when repairing and replacing old crawl space piers.
  • Push Piers: Push piers are steel tubes that are driven into the ground beneath the foundation to provide additional support and stabilize the structure long-term. They are often used in concrete slab foundations where structural damage like settling or sinking has occurred, and jacks are not a viable alternative
  • Helical Piers: Helical piers are similar to push piers but have helical plates attached to them. These plates help the piers to be screwed into the ground, providing stability and support to the foundation.

These are some of the main types of foundation jacks used in foundation repair jobs. Each type has its own advantages and is chosen based on the specific requirements of the project.

Foundation Jack Installation Repair: Steps and How Long It Takes

When it comes to foundation jack installation repair, understanding the steps involved and the time it takes is crucial for ensuring the stability of your building’s structure.

Here are some key points to consider:

  1. Professional Foundation Inspection: Foundation repair professionals will inspect the foundation walls, crawl spaces, and floor joists to determine the extent of the damage and the best approach for repair.
  2. Plan Created: A plan and budget are created depending on your property’s needs, how much of a problem the foundation settlement and what it will take to get it back to its original level and state. 
  3. Installation of Foundation Jacks: The repair process typically involves installing adjustable jacks under the affected areas to provide support and prevent further shifting or settling of the foundation, getting it back to its original position. If needed, push or helical piers might also be installed.

Time Frame: The duration of foundation jack installation repair can vary depending on the complexity of the issue. While some repairs may be completed in a few days, more extensive repairs could take several weeks to ensure the structural integrity of the building.

Are Floor Jacks Permanent?

One of the most common questions about jacks is if they’re permanent or not. 

The answer is that it depends.

Let’s explore these distinctions to guide you in choosing the right type for your foundation needs.

Difference Between Temporary and Permanent Floor Jacks

When it comes to floor jacks, understanding the difference between temporary and permanent options is crucial for making the right choice for your needs.

Here are some key points to help clarify the variance between temporary and permanent floor jacks:

  • Installation: Temporary floor jacks are usually easy to install and remove, making them ideal for short-term support needs. Permanent floor jacks, on the other hand, require a more complex installation process and are designed for long-term stability. They are most often referred to as “piers” or “steel floor jacks” and not jacks, although some, like bottle jacks, can serve as permanent solutions to crawl space foundations as well. 
  • Durability: Temporary floor jacks are typically made of lighter materials and may not withstand heavy loads over extended periods. Permanent floor jacks are constructed with more robust materials to provide lasting support, like steel.
  • Adjustability: Temporary floor jacks are often adjustable to accommodate different heights, while permanent floor jacks are set at a fixed height to support the structure consistently.

Steel floor jacks or piers like helical piers are the true permanent solution for sustaining your home.

Understanding these differences can help you choose the right floor jack for your specific needs.
