Having a skate park in your home could be a fun bonus for the kids and kids at heart, but not at the expense of your loved ones’ safety and the structural integrity of your home. If your concrete slab floors look and feel like they could be a skateboarder’s haven, you could have big problems brewing underneath your home.

Unevenness and cracks spreading through the concrete floors in your home or garage mean it’s time to call a professional for assistance. While seeing these problem signs in your home can be alarming, there are various reasons for their occurrence and different ways to fix them. Of course, repair methods will vary depending on the underlying causes of the damage and the co-occurring issues.

That’s where the expert team at FSM comes in. Our experienced professionals know the ins and outs of concrete slab problems and repair solutions. We can investigate what’s going on in your home and then recommend the course of action best suited to your repair needs. Read on to learn more about these issues and solutions.

Why Do I Need to Lift My Interior Concrete Slab Floor?

Floor Cracks

A few dips or cracks in your concrete slab floors might not seem like huge issues, but they can end up being dangerous problems the longer they are neglected. While concrete is a widely used in construction because it is durable and long-lasting, the materials can become brittle, crumble, or fail with time.

But, if you are vigilant about the state of your concrete and you catch problems like cracks and sinking in time, professional contractors can help you restore and protect your concrete floors with interior slab lifting solutions. There are so many benefits to doing this, including:

Helping Prevent Further Damage

Damage will only worsen over time the longer it is not fixed or fixed with inappropriate solutions. This typically leads to more time-consuming and expensive repairs in the long run. So, taking action in a timely manner to correct any problems is in your best interest as it can extend the interior slab’s life and reduce the risk of further damage.

Each problem typically needs its own unique solution. This is why it is critical for an expert to assess your concrete floor and determine exactly what issues are at play. With a customized solution, you can save time and money while regaining your secure, stable floor.

Maintaining Appearance and Functionality

While interior slab floors have a simple job, they can easily become unsightly tripping hazards if they fall into disrepair. A floor with cracks and dents also seems untidy and neglected. 

Maintaining the look and function of your interior slab is important. Not only are you investing in your home’s aesthetics, but the overall structure and value of your home as well. By investing in concrete repairs and interior slab lifting, you can rejuvenate your floor’s aesthetic appeal. This can improve the real estate value of your home while also making it a more pleasant living environment. Wherever the concrete is in your home, you can’t help but interact with it, so repairs benefit you in the long run.

Avoiding Injuries

As we’ve just mentioned, concrete floors with problems like cracks and unevenness can present serious tripping hazards. Anyone walking over floors in severe disrepair risk tripping, falling, and sustaining significant injuries, whether they are young children, the elderly, or have mobility issues. This makes interior slab lifting and repair even more critical.

Protecting Your Home’s Structural Integrity

There’s a good chance that your interior slab floors are connected to or are a part of the foundation of your home. If your interior slab floors are cracking or damaged somehow, this can also impact the condition of your foundation overall. Your foundation is what supports the entire structure, so having a sound foundation is highly important. When you repair and maintain the condition of your interior slab floors, you also are protecting your home’s foundation and structural integrity and ensuring its longevity.

Adding Value to Your Property

In a similar vein, any repairs that restore and protect your concrete floor go a long way toward appealing to prospective buyers. During showings, gaps in the surface and cracking areas are not overlooked. Potential buyers see these issues as dangers they may need to fix themselves, or at least an eyesore they shouldn’t have to pay full price for.

It is not a luxury to have a well-maintained concrete floor. It’s an opportunity that will pay off in the long run. This investment will increase your enjoyment of the home and lower your maintenance costs, as well as boost its value.

How Do You Repair a Damaged Concrete Floor?

The repair methods for addressing a damaged concrete floor vary depending on the type of damage and its extent. Some measures may work better for the interior slab than others. That’s why you need to seek advice and guidance from experienced local repair contractors. The damage could only continue to worsen if you end up using the wrong solution. Let’s take a closer look at ways interior slabs can be repaired.

Concrete Replacement

If concrete problems have been left to worsen to the point of extreme disrepair, the only solution may be to completely replace and repour the concrete. This is an extensive undertaking that can require a lot of time, money, and heavy equipment in order to remove the existing, damaged concrete floor. Once the damaged flooring has been removed, new cement will be mixed and poured before being left to cure.

This whole process can take a few days, even more depending on the temperature and climate at the time the work is undertaken. This makes it inconvenient, as well as expensive and potentially destructive to your home. Worst of all, concrete replacement tends to end with the recurrence of most forms of damage. This is because it does nothing to address the underlying problems that are causing sinking and cracking in the concrete floors.

Foundation Piers

As previously mentioned, your interior slab could be closely tied to your home’s foundation. If the problems affecting your concrete floor also are impacting your foundation, you may need certain foundation repair solutions installed. When it comes to these types of repairs involving the foundation and floor, foundation piers are typically employed.

Whether they are helical piers, push piers, or slab piers, these methods are used to stabilize settling foundations and can even help lift them back towards their original positions. These will not repair the look of your concrete floor but will prevent the cracks and damage from recurring after your floor is resurfaced.

Concrete Lifting

If you catch the problems with your concrete floor in time, you can invest in interior slab lifting measures.

The traditional method used for many years, mudjacking, is a dated procedure that is invasive, expensive, and not effective in repairing or lifting problematic concrete. The heavy concrete slurry pumped under slabs through sizeable holes may lift and hold the slabs up for a few years, but it is a temporary solution at best that does not get to the root cause of the failing concrete.

A much more effective method – that still uses the basic concept of mudjacking – is the innovative PolyRenewal™ polyurethane foam injection system. Instead of soda can-sized holes that have to be drilled with mudjacking, only penny-sized holes have to be created with this system. And the material injected underneath the concrete is very lightweight, but quite durable and long-lasting. It expands to fill the entire void under the concrete slab to properly lift it back to level, and its quick cure time of 15 minutes allows you to walk on the concrete immediately after the installation project.

These are just some of the reasons that make PolyRenewal™ an excellent choice in interior slab lifting and repair.

Interior Slab Lifting


Damaged concrete floors are not just unattractive. They can be actively dangerous to your home and health (depending on the secondary issues that they cause). Dampness, mold formation, and a pest infestation, for example, can come with damaged floors.

Book a Professional Inspection

It’s important that you have your home inspected as quickly as possible when you notice these signs of damage to your concrete floors. After all, damaged or sinking floors are a sign of deeper structural issues at work. Conducting your own inspection can be helpful, but a professional assessment is best for a number of reasons.

First, a professional assessment will include other areas of your home and highlight red flags for connected issues. This will help you to plan for the future, or even address the secondary and tertiary issues in your home at the same time as your damaged concrete floor. Also, a professional inspection generally comes with an estimate. This will give you an understanding of what is wrong and how much it will cost to repair.

Concrete Lifting Services

Before you can even think about repairing the look of your damaged concrete flooring, it is necessary to lift it back into place and ensure that it is appropriately supported. Concrete lifting services are key in this endeavor. Generally speaking, you have a few options for lifting sunken concrete. Firstly, there are slab piers, which are reliable and work in the same way as foundation piers.

Additionally, the PolyRenewal™ system is an option for effectively lifting cracking and uneven concrete floors that do not have serious structural issues. This method is far more effective and permanent than its mudjacking predecessor. As a polyurethane foam, PolyRenewal™ is a lightweight, water-resistant, and durable option for concrete floor repair. As such, it is far more suitable for sunken concrete that is sinking because it is too heavy for the surface that it rests on.

These solutions, however, it is not advisable for you to take on these projects yourself. Many solutions such as PolyRenewal™ are only available through experienced contractors. So, it is well-worth your time and investment to see professional assistance for concrete floor lifting and repair.

Before you even figure out how to fix uneven floors in a home, you’ll first want to learn what causes them. Several reasons might cause a home to develop uneven concrete floors.

Weak Soil and Heavy Weight

If the soil underneath the concrete slab was already weak, the chances of having uneven concrete slabs go up substantially. That’s because weak soil often reacts easily to pressure and weight, both things that a concrete slab often has in ample measure. Typically, this occurs if the initial construction crew didn’t prepare the soil properly.

If you’ve placed too much weight on a concrete slab, you may also have uneven slab problems that have nothing to do with an inherent issue of the concrete. This doesn’t happen frequently, but it is possible for there to be serious movement problems if you add something heavy, like marble countertops, on top of a concrete slab.

Erosion Under the Slab

Erosion underneath your home’s concrete slab is a possible concern, especially if you suddenly experience a lot of rain or floodwater in an area and your home doesn’t have a basement or crawl space. Erosion underneath the concrete slab typically causes all sorts of movement problems and it can evolve into issues with sinking.

Soil erosion is a surprisingly common concern. It can be much worse in areas that have especially expansive soils, as it can sometimes move away with water more easily. You might want to talk to an expert if you have a lot of water around your home to make sure you’re avoiding erosion as much as possible.

Learning to spot the early warning signs of damage to your home is essential if you are to prevent problems from becoming more serious than they need to be. There are many different problem signs associated with structural damage around a property, but those that are most likely connected to flooring damage are:

Sunken Concrete or Spreading Cracks

The most obvious sign of damage to a concrete floor is unevenness or sinking sections of concrete. These can be caused by several issues but will inevitably require professional intervention to ensure proper and permanent repair. The most common causes of sinking concrete flooring are foundation damage and weak or loose soil (depending on the location of the floor in question).

If you notice cracks in your floor that are actively growing and spreading, you should prioritize a professional inspection of your home. Spreading cracks are a sign that serious and ongoing pressure is present in your home. As such, the cracks are a warning sign you should not ignore.

Dampness, Mold, and Mildew

Humidity and dampness are very general warning signs, but that doesn’t mean you should ignore them. If you notice signs of dampness like condensation and standing water around your home, you should investigate to find other warning signs that can help you to contextualize the problems at hand.

Mold and mildew formations are a sign of advanced dampness in your home and can also be used to pinpoint problem areas for further investigation. Look for patches of intense discoloration and the presence of a slightly sweet and musty smell in your home.

Can You Lift Interior Concrete Yourself?

It may be tempting, now that you know some of the ways interior slabs can be lifted and repaired, to run out to your local hardware store to gather supplies and take on the projects yourself. However, even in an age with more DIY enthusiasts, this is not a project you can take on by yourself or even with the help of a friend.

Repairs specific to interior slabs can be complicated and time consuming. Many solutions, including PolyRenewal™ are not readily available through your local hardware store, and even if you’re able to get your hands on similar products, these often-one-time use tools and materials can be very expensive. Without the right training and experience, it’s possible you might not use the right solution to fix your interior slab problems, thus inadvertently covering up the real issues or making these underlying problems worse.

Whereas when you seek assistance with your interior slab from an experienced professional, you’ll reap so many benefits. These experts can not only properly diagnose your concrete problems but employ the right solution the first time around to fix the specific issues at play. They also have years of experience and knowledge backing them up, as well as access to the best equipment to install effective, long-lasting repairs. In the same vein, some solutions like PolyRenewal™ are specialized items only available through expert contractors like FSM.

So, it is best to leave the repairs to someone who knows the ins and outs of interior slab lifting and repair.
