When gravity begins to behave strangely in your garage, you notice that its floor is no longer flat. This may happen due to various reasons.
However, there are several options for fixing uneven concrete garage floors. Nonetheless, I have gone through the trial and error process and discovered the most efficient method that will do the job permanently.
Unfortunately, you will require assistance if you are not skilled in these fields.
Why Garage Floor May Become Uneven
There might be several causes for an uneven floor, but we’ve compiled a list of the top five:
If you live in an area where it rains frequently and floods, this might be one of the causes of your garage floor being cracked and uneven.
Water causes the concrete to weaken over time, causing it to be ruined. Not only flooding, but any continuous fall of fluids can also transform your garage into an uneven place.
This one is not on you but on the builders who did the compaction of the soil! They probably didn’t give an effort to make the soil stick to each other properly. Thus, leaving more space between each other and leaving the soil less dense which is easy to be removed.
Too much moisture, like too little, is terrible for your concrete. In a chilly climate, a garage’s concrete may get excessively damp. As a result, the concrete begins to expand, leading to cracked flooring.
4. Soil Condition
Uneven flooring is frequently caused by soil conditions. When the soil on which the concrete is placed becomes too dry, the soil expands in volume, and the concrete cannot cope.
5. Poor Foundation
Poor foundation is another major cause. If the concrete mix is not carefully prepared for the condition of your garage floor, it will most likely fail. When the foundation is not best equipped, concrete is extremely sensitive.
Should a Garage Floor Be Level?
It doesn’t depend on whether it’s a garage or not. Rather it’s dependent on the depth of the cracks or unevenness your garage’s floor is currently in. Nevertheless, leveling a garage floor is only best when the damage is not too much and can be solved easily.
On the other hand, if your unevenness is not so much then going with it is not a bad choice either. But mostly, these levelers are used to smooth out a concrete garage floor.
Furthermore, this method is less expensive and requires practically little assistance. On the contrary, to execute it correctly, you’d need a considerable amount of time and certain expertise.
How to Fix Uneven Concrete Garage Floor
Undoubtedly the only way you can fix and level an old uneven and cracked garage is by using the famous Slab Jacking method. Here, we lift the concrete slab back to the position it was originally in and thus are known to be the most effective out of all of them. Here’s how you do it;
Step 1: Determining the Uneven
You’ll need to figure out which area of the floor is uneven and needs slab jacking to balance it out. To determine the uneven space in your garage, use levels or even string lines.
Step 2: Setting Up the Drill Machine
The first thing you need to keep in mind is the diameter of the drilling machine. You need to drill through the concrete here so taking the correct number is very important as you will inject the foundation from here.
We recommend you use a drill machine with a diameter of about 3.5 inches to perfectly inject the cocktail.
Step 3: Drilling Hole in the Floor
In this instance, you must drill holes in the uneven sections. The amount of holes you need depends on how uneven your concrete garage is.
However, we are unable to give you a precise estimate of how many holes you will need to drill. It is entirely dependent on the area you are trying to cover and meaningless to give you an estimate.
If you have the necessary experience, you will be able to tell. But, if you don’t, you’ll have to recruit someone who does.
Step 4: Prepare the Concrete Mix
You’ll need to make your concrete mix for this step. To build your mix, combine sand, gravel, and ash with water. To prepare it on your own, get a bucket and a corresponding quantity of them.
Step 5: Injecting the Mixture
There has to be a place where you can put that mix to inject it with pressure within the holes. You can do this with slab lifting pumps.
Making multiple holes rather than just one serves two purposes. The first is for lifting the slab, and the second is for filling voids, such as repairing the large uneven cracks in the concrete floor.
Spreading and providing the highest lift capacity by putting the concrete mix through one hole will raise the uneven floor. On the other hand, injecting into the other holes will push the entire slab and fill up the gaps.
Step 6: Cover up to Finish
After you’ve finished lifting, you’ll need to fill up the holes, otherwise, what’s the point? To fill the holes, simply use cement and a scraper to fully cover them up and level them with the floor.
That’s it! The uneven concrete garage floor has been effectively fixed.
However, you won’t be able to utilize the garage right away because it needs to recuperate before applying any pressure. Nevertheless, you can surely walk on it. In most cases, your car should be ready to be parked there within 3-4 hours.
How Do You Level an Existing Garage Floor
Repairing your floor is a lot of work and far too pricey to endure. On the other hand, uneven flooring is a headache to clean. So leveling the garage is the most sensible alternative.
While most individuals are stumped as to how to level a concrete floor, we have come up with the cheapest way to level a concrete floor. As a result, you can do it effectively and affordably yourself.
Let’s see how to do it in a step-by-step manner.
Step 1: Baseboards
The first step would be to remove all of the baseboards along the walls’ sides. You probably don’t want them to get messed up.
Step 2: Prepare the Surface
Clean the surface of your floor correctly with anything that can draw out pressurized water. Especially where the surface is too uneven.
Step 3: Prime the Floor
You’ll need to prime the floor with a mixture of your floor primer and water. In most cases, the ratio is 1:3.
Step 4: Prepare the Solution
Take a bucket and mix concrete with a self-leveling compound. Stir it for a few minutes and it should be as creamy as possible.
Step 5: Pour the Solution
Pouring the solution correctly is the toughest job. Slowly pour the solution into the uneven parts of the floors. You will notice the solution taking itself in position.
Step 6: Scrape the Mixture
After giving it a minute, take a long handle scraper and gently mix the solution with the floor evenly.
Step 7: Wait Till it Done
Your part of the job is done! All you have to do is wait a few hours and your floor should fix low spots on a garage floor.
Garage Floor Leveling Compound vs. Slab Jacking
Now that we have gone through the ultimate method called slab jacking, you are probably stuck between these two. Wondering should use the leveling compound or the slab jacking one.
Well, we can always do a Pros and Cons list for you to find the perfect fix. Let’s check it out!
Talking after a lot of trial and error, slab jacking is the most effective one here. If you think about it, the leveling compound is only used to give a finishing touch to the floors. Whereas, slab jacking will provide you with an almost new-built foundation under the concrete.
Undoubtedly, they will last way longer than any leveling compound!
Level a garage floor if you are on a budget. As you can already tell that slab jacking can get expensive compared to buying leveling compounds. There is a need for extra tools for slabbing. Whereas, slabbing takes only a few household tools.
Additionally, slab lifting would involve the hiring of certain experts in this field. If you have enough time on your hands, you can level your floor without any prior experience.
If your garage is constantly in use, leveling is not a good idea. You won’t have enough time to wait for the concrete to dry and be ready to use with leveling chemicals.
On the other hand, slab jumping requires more effort than leveling but saves time. In a few hours, your unevenness will be gone, and you’ll be able to resume your usual schedule.
Can You Use Self-leveling Compound On Garage Floor?
Using a self-leveling compound for leveling low spots on the concrete garage floor is doable. Furthermore, when you don’t have any assistance, self-leveling chemicals are a major bonus. Instead of wasting time improving the fluidity of concrete, self-leveling compounds use far less water to get prepared for use.
Remember to prepare your garage floor before you begin pouring compounds into it. It will not fix your uneven flooring but instead worsen them. Moreover, spreading them properly is another thing to keep in mind.
What Do Uneven Floors Mean?
After a given amount of time, the foundation of the floor can no longer keep up, resulting in an uneven floor. An uneven floor might indicate anything that isn’t quite right. Uneven surfaces include anything from slanted floors to cracks. Furthermore, when the base of the floor ages, the floor may begin to bounce.
Unlike how it was originally arranged, these columns have separated themselves from one another. There are a lot of problems with an uneven floor. To begin with, people are just uncomfortable walking on an uneven surface. Second, because of its defects, it detracts from the environment of the garage or area.
Additionally, if uneven flooring goes overlooked when moving heavy items in a garage, it might cause injury. The most common issue with an uneven floor is that the door does not open correctly owing to the slant.
Can you Use Self-leveling Concrete in a Garage?
If the slants are not overly inclined, self-leveling concrete might be a decent solution. Furthermore, self-leveling concrete is the ideal option since it dries faster than traditional compounds.
Mold, which is your base becoming bigger every day due to the causes listed above in the article, is a typical problem in garages. On the other hand, self-leveling concrete will work extremely well to effectively block this.
As a result, high moisture, low moisture, or even cold weather would have less of an impact on your garage than before. Also, it is superior to utilizing only concrete.
How Much Does Self-Leveling Cost?
The question is can you do the self-leveling by yourself? If you hire workers, the overall cost of the project will be higher. Likewise, if you do it yourself, the cost is significantly reduced by a few times.
However, the cost of the self-leveling concrete is $1.80 to $5 per sq. You can factor in the cost of labor in your area.
Can you Level Garage Floor With Thinset?
If you want to place tiles on your garage floor, you may use thin-set. Nevertheless, thinset can only be used with cement floors, so keep that in mind. If you have concrete flooring, thinset is not a good choice.
However, if you only have a few minor holes in your flooring, a modest amount of thinset would suffice.
Can you Use Cement to Level the Floor?
It’s impractical to level floors using cement. While concrete is the entire product, cement is only a portion of it and cannot be expected to perform.
Furthermore, cement is the most unstable material to utilize for floor leveling. You may like the effects at first, but in a few days, you will regret it.
How to Resurface a Concrete Garage Floor
Small cracks of half an inch can be resurfaced so they no longer absorb liquids and removes the ambiance from your garage. Resurfacing will fill up cracks and make the surface as smooth as sparkling.
Let’s check how to do it correctly!
Step 1: Cleaning
Oil and sticky materials are typical in garages. Clean the floor well with a detergent first. After that, take a blower and use it to soak up all of the leftover floor residues for a thorough clean, which is critical.
Step 2: Removing Adhesives
Scrape off any paint or adhesives from the floor that might harm the resurfacing process with a scraper.
Step 3: Moisture
You’ve just killed two birds with one shot. To add the last touch of cleaning, you should moisten the floor with water and utilize pressured water.
Step 4: Mixing Floor Coat
Fill a bucket halfway with water and mix the floor coat thoroughly. After a minute, give it another stir to ensure that the solution is smooth.
Step 5: Fill the Holes
Take the solution and put a limited amount of the floor coating in the holes and don’t overflow.
Step 6: Effective Scraping
Take the scraper once again and carefully slide it to one side and then to the other. Always remember to be kind. After scraping a few times on a single line, steadily spread the coating out and scrape.
How Much Does it Cost to Relevel a Garage?
There are many costs involved with fixing uneven concrete garage floors.
However, the most expensive cost would be hiring professionals to level your garage. To give you an idea, the whole cost, including the equipment, is estimated to be roughly $750. However, it is entirely dependent on the size of the area to be covered.
To summarize, there are two methods for repairing uneven floors, with slab jacking being the most effective. The technique here is to mend the uneven floor from the bottom up, rather than the top, which may become uneven again.
On the other hand, fixing it from the base will allow you another few years before it needs to be fixed again. Thus, making it the most durable option.
However, I must also mention that this is a pricey repair. To accomplish so, you’ll need to hire pros. In contrast, with self-leveling, you would only need a leveling compound and a few experiences to do the job.
