Crawl Space Foundation Repair
The crawl space is a vital part of your home’s structure. However, there are unique, inherent problems with crawl space bases, such as basement heave and settlement. Therefore, you’ll likely run into some issues eventually.
Repair solutions can stabilize and even lift your crawl space foundation back into place. A problem usually gets worse over time the longer it is left untreated. For this reason, it’s critical to address any crawl space issues as soon as they arise.
Here, we’ll discuss the most common causes of problems with crawl space foundations. After that, we’ll outline some repair options and how to prevent and protect foundation issues.
Understanding a Crawl Space Foundation
Even so, what exactly is a crawl space foundation? It’s a standard choice for building on stable ground. The crawl space between the ground floor and the house’s first floor is created by the footings and walls that make up the foundation, which raises the house off the ground.
There is barely enough space to crawl about on the foundation—roughly 1.5 to 3 feet—but not enough to stand on. The foundation is intended to hold up joists, grinders, and beams. It also provides simple access to the house’s electrical and plumbing systems for maintenance.
Crawl Space Foundation Repair Options
Foundation repair is vital for any building, including your house, to remain safe and structurally sound. Now that you know why crawl space floors sustain damage, you must know how to make the required repairs.
The kind and extent of foundational damage determine the best repair strategy. Therefore, choose the damage you’re dealing with before starting a project like this.
- Install heavy-duty supports
Installing sturdy metal support on each base is one of the finest ways to repair damage to your foundation. Verify if the metal is galvanized steel. It will be resistant to corrosion and have long-lasting adaptability. When placed correctly, it has an average lifespan of 25 years.
Because it strengthens the soil that they are resting on, this restoration method is the best one.
- Light-Duty Jack Posts
A light-duty jack post is yet another fantastic repair choice. More seasoned contractors frequently utilize this technique to repair damage to the crawl space foundation. If they are installed correctly, light-duty jack posts will support the drooping girder.
However, this repair technique is called a stopgap due to its limited bearing capacity and propensity for rust or corrosion. Additionally, it may sink into the earth, which could eventually cause more structural sagging.
- Install concrete masonry unit columns
Installing a concrete masonry unit column may resolve your crawl space foundation problems. This is the best repair technique for homes whose foundations are sinking. Raising the floor will allow you to add more concrete columns to the crawl area. The spaces between each column and the floor can also be filled in via shimming.
- Removing and replacing damaged wood
The best action is to replace any decaying wood harming your crawl space foundation. It is crucial to remove all rotted timber and replace it with new. The beams will be strengthened when the whole thing is rebuilt with fresh wood.
However, this approach will only persist when mold and moisture damage are fixed. Handling any water and humidity sources will also be vital to guarantee a longer-lasting solution.
Causes of Crawl Space Foundation Problems
Finding the source of your flawed foundation is essential before you take any action. This will assist you in selecting a suitable approach to use. Crawl space foundation issues can have a wide range of causes nowadays. The most frequent ones are poor drainage, inadequate screw jack installation, and insufficient support piers in the crawl area.
- Incorrect Installation of Screw Jacks
A crawl space foundation must include screw jacks. Their purpose is to offer stability and shield them from moisture and rust. Moisture in the crawl area might deteriorate these parts if they are not waterproofed or installed correctly at the grade level.
- Rot, mold, and moisture damage.
Your crawl space foundation may sustain severe damage from these three forces. A moist or damp crawl area encourages the growth of mildew and decay. The structural timber in your house will eventually suffer harm from this mold, and your building will start to sag when this occurs.
- Poor Drainage System
Over time, a crawl space foundation’s inadequate drainage system might lead to severe damage. Typically, wooden block piers are designed to offer stability to these foundations. An inadequate drainage system can result in wet and soft soil. At this point, the wooden block piers will rot and become too weak to hold up the floor.
- Limited Support Piers in the Crawl Space
A sufficient number of support piers in the crawl spaces may damage the foundation, causing the floor to no longer support you properly. This is why it’s critical to check your crawl space’s foundation routinely. In this manner, you may spot any problem before it gets out of control and avoid spending a lot of money on remedies.
- Stabilized Support Piers Are Not Vertical Anymore
This is an extra element that could call for crawl space foundation repairs. The settled support piers will only offer the best support if they are vertical. When placed in expansive soil, this support frequently loses its shape.
When they absorb moisture, they expand, and when they dry out, they contract. This back-and-forth movement of the ground could crack the support piers.
- Cracks
The foundation of your crawl space could crack for several reasons, including changes in temperature, hydrostatic pressure, and structural issues. If neglected, it will cause serious harm that will be more expensive to repair.
Fortunately, early detection corrects foundation fractures. Therefore, it is critical to regularly check your crawl space foundation for cracks.
Warning Signals
We want to highlight a few red flags for crawl space foundation degradation before we wrap up our conversation. This will assist you in locating the issue before it worsens and requires more expensive repairs. A few indicators of damage to the crawl space foundation are increased humidity, furniture that wobbles when someone walks by, cracks in the wall or tile, moisture, a musty odor, and more.
You must respond right away if there is damage to your crawl space foundation. If not, the issue will worsen, and more cash will be required. You can use the above-highlighted repair solutions to address foundation difficulties. It is advised, therefore, to leave the work to the experts. They may then guarantee that the foundation of your crawl space is adequately fixed.
