Foam Injection Vs Pressure Grouting

Foam Injection Vs. Pressure Grouting in Lexington, KY


If your concrete slab begins to show signs of cracking and damage, United Structural Systems can help fix it. There are several options for concrete slab repair, including foam injection and pressure grouting from our Charleston and Lexington commercial concrete repair team. To determine which solution will best fit your needs, take a look at the options below.

Foam Injection

The process of foam injection is relatively straightforward. First, our Charleston and Lexington commercial concrete repair experts will drill small holes into the concrete slab and then inject polyurethane foam into the holes. The injected polyurethane foam spreads underneath the concrete, filling any gaps and spaces beneath the slab. This process ends up lifting the sinking section, thus leveling the concrete. 

One of the main benefits of foam injection is its cure time. Polyurethane foam cures rapidly, allowing you to regain the use of the area in approximately 30 minutes.

Pressure Grouting

Pressure grouting also gets applied through holes drilled in the concrete slab. Our Charleston and Lexington pressure grouting is a mixture of fine limestone aggregate and water (and sometimes cement). This mixture gets pumped into the holes using a precision application method. The injected grout fills the voids or weak layers. As it sets, it strengthens the surrounding soil, stabilizing the ground underneath the concrete slab and leveling any uneven portions.

This method does take longer to cure, leaving you without a usable space for a lengthier amount of time. If time is not your primary concern, pressure grouting is a great option, especially for commercial applications. Choosing pressure grouting for your Charleston or Lexington commercial concrete slab repair may help you avoid the costly and lengthy process of digging up entire sections.

The experts at United Structural Systems are here to help you with all of your Charleston and Lexington commercial concrete repair needs.
