Garage Floor Leveling Methods

If you’re experiencing holes, breakage, or unevenness in your garage floor, there’s a solution for it. There are different causes of unevenness in a garage floor which include bad installation, moisture, and cracking. A damaged garage floor becomes a potential danger to users, however, with the methods listed below you can flatten your garage floor and make it even again.

  • Use of a leveling compound

You can fix the uneven parts in your garage floor using a mortar or a leveling compound. You can measure the parts that are uneven or out of level on your garage floor using a long spirit level. This is something you can do on your own without the assistance of a professional technician. You can buy the self-leveling compound yourself.

Use of a leveling compound

The leveling compound isn’t expensive and is best used on fairly localized dips and sags. The leveling compound however will not be effective if the uneven part on your garage floor is bigger. 

There are processes to using the leveling compound which is cleaning spilled oil on your garage floor, abrading the concrete then vacuuming it. This enables the leveling compound to stick properly on your garage floor. 

To apply the leveling compound, draw out the affected areas on your garage floor with a pencil then apply the leveling compound on the marked part. Allow the level compound to cure for a whole day or more and when it is dry, you can proceed to paint it or apply a sealer if needed.

  • Slab jacking

Slab jacking is a method used to repair settling concrete and you can also use it for leveling your uneven garage floor. This technique can also be called concrete raising or mud jacking. 

This method can only be done by trained technicians who have the right experience and tools. So you need to hire a flooring professional for this. 

Slab jacking is done by injection but before that, the technician will determine the affected slab(s). After that, he will identify the places that need to be filled and drill holes in those areas. These holes will then be filled with a cement slurry or mixture. 

Some factors need to be considered while determining the places to drill the holes such as the elevation difference, location of cracks and joints, drainage conditions, length of the garage floor to be raised, and the subgrade.

Some holes will be drilled into your garage surface which will be about 3 inches deep after which you can decide to fill it with slurry or polyurethane foam compound. Most technicians prefer using polyurethane to any other mixture but it’s more expensive than slurry.

Also, the technician filling the holes with a slurry mix or polyurethane foam compound should be careful to not inject too much of these mixtures; instead, the filling should be even throughout the holes.

After filling the holes with the mixtures, the holes should be covered with cement so a sealer can be applied or it can be painted if necessary.
