Concrete Leveling

Correct uneven surfaces with professional concrete leveling in Johnson City. This home improvement project promotes a better structure foundation by working on the concrete surface it stands on.

Are you wondering if you need concrete raising to improve your home’s curb appeal? We’re here to help. Here’s everything you need to know about concrete leveling.

When Is Concrete Leveling a Must?

When it comes to concrete lifting you have three options:

Slabjacking

Otherwise known as “pressure grouting,” this specialty concrete raising option lifts sunken concrete slabs by injecting/pumping a substance that pushes it up from below. 

Professionals start the slabjacking process by drilling strategically located holes in the concrete, which maximizes the lift. Next, the void space is filled with injections to lift the concrete. Once all of the slabs have been lifted, professionals will patch the holes and complete the work.

The benefits of slabjacking include:

• • Significantly lower cost than new concrete
  • Maintenance of aesthetics (since the process does not disturb the current landscape)
  • Timely repairs
  • Minimal or no impact on the environment

On the other hand, the cons of slabjacking include:

• • The risk of new cracks as you lift the slab
  • The concrete must always be in good condition; otherwise, a replacement is a better option
  • Resettlement; concrete poured on poorly compacted soils can cause the concrete to sink further.

Mudjacking

Mudjacking uses a mixture of portland cement and topsoil to hydraulically lift the concrete slabs. However, you can achieve this method by using a variety of other mixtures. The most common mixture includes a sand blend or some local soil, mixed with cement and water. 

Similar to slabjacking, professionals will drill holes in the concrete before they inject the “mud” mixture under the slabs. Once the void has been filled, the pressure under the slab will lift the concrete back into place. 

The benefits of mudjacking are:

• • • Better control over the lifting of the concrete slab
    • Low-pressure slab lifting
    • Higher compressive strength 
    • Easier access to equipment
    • Friendlier to your budget

The cons of mudjacking, on the other hand, include the following:

• • • Slower process due to the smaller material volume
    • Larger access holes (compared to the other two concrete raising options)
    • More clean-up afterwards
    • Shorter warranty periods

Limestone Grout Leveling

This concrete leveling option uses pulverized limestone (aka “agricultural lime”). The limestone is mixed with water and, in some cases, Portland cement to create a thick slurry. The semi-fluid nature of the slurry effectively fills the void that lifts the concrete slabs into place. After filling the void, cement contractors can precisely control the lift of the slab. Once everything is in place, the contractors will fill the access holes with color-matching grout. 

Benefits of limestone grout leveling include:

• • • Finely controlled and low-pressure cement slab lifting
    • Smaller holes compared to mudjacking
    • Sustainable and eco-friendly
    • More affordable compared to the previous options

On the other hand, the disadvantages of this option are:

• • • More clean-up afterward
    • Rainwater can erode the limestone if you don’t have enough cement
