If you’re searching for information on how to level a patio, look no further because you’ve landed on the right page!

The best way to level a concrete patio is by using a concrete leveling technique known as polyurethane foam injection, or just polyjacking for short. Polyjacking quickly raises and levels an uneven concrete patio surface and provides a long-lasting solution.

Polyurethane foam injection should only be performed by a professional because it requires training, experience, and special equipment. Keep reading to learn more about this process and why it’s the best option for leveling concrete patio.

Why Polyurethane Foam Injection Is The Best Method For Leveling A Concrete Patio 

Polyurethane foam injection is usually the best method for leveling a concrete patio because,

  • It’s a quick solution. Most jobs take no more than a few hours tops, and then you can start using the patio again. Pouring new concrete requires a certain amount of downtime as the fresh concrete dries and hardens.
  • Polyjacking is less expensive than tearing up the patio and pouring new concrete.
  • With concrete leveling it isn’t necessary to disrupt the landscaping.
  • The foam is lightweight and won’t contribute to future settlement.
  • Concrete leveling is minimally-invasive. The foam is injected under the concrete patio through small holes that will be patched and virtually invisible when the leveling is complete.
  • It’s environmentally friendly and waterproof. The polyurethane foam resists water and will not leach into the ground.

How The Concrete Leveling Process Works 

Here’s how to level a concrete patio using polyurethane foam injection:

  • The first thing we do is drill small, dime-sized holes into the affected area of the concrete patio. Don’t worry. These will be patched after the repair is complete.
  • The polyurethane foam is pumped under the concrete patio via the small holes.
  • As the poly foam expands, it fills any voids beneath the patio’s surface, raising and re-leveling the slab.
  • After the lifting is complete, the holes are patched with a compound that is similar to the color of the concrete.

As the foam expands, it fills the voids and lifts the sidewalk back to level.

When done properly by a professional, leveling a concrete patio using polyurethane foam injection offers a lasting and dependable solution.

The Benefits Of Having A Level Concrete Patio  

Having a level concrete patio has many advantages to consider, including the following:

  • A level concrete patio is essential for safety reasons. Unlevel patios are trip hazards and a liability. If someone gets injured, you could find yourself facing an unpleasant lawsuit should someone decide to sue.
  • An unlevel concrete patio is an eyesore. Leveling it will improve the look of your outdoor area.
  • A beautiful, level patio adds to your home’s resale value.

Sidewalk leveling involves injecting something under the uneven slab to lift and level it.

How To Find The Right Professional To Do The Job  

Homeowners looking for a professional to level their concrete patio need to research potential contractors carefully. Here are some things to look for:

  • Always ask for references and ensure the foundation repair contractor has experience using polyurethane foam injection to raise concrete slabs like patios, sidewalks, driveways, etc.
  • Don’t look for the least expensive offer and automatically go with that. Saving money now might seem like a good thing. However, if the job isn’t done correctly, you may pay much more later to fix the damage that could have been avoided if the repair had been done correctly the first time.
  • Look at reviews online and speak with previous customers to get a clear understanding of the contractor’s quality of service before committing.

Wondering how to level a concrete patio? Polyurethane foam injection is quick, minimally invasive, and cheaper than tearing up and replacing the slab.
