Polyurethane Foam Injection: The Best Solution for Concrete Lifting

“Your home is only as strong as its foundation” is a phrase that rings true amongst all homeowners across the Carolina’s. A weak or compromised foundation can both affect your home’s stability and be a burden on your family. Houses are built on top of concrete slab foundations and experience a degree of natural settlement over time. However, concrete slabs begin to sink and crack when settlement becomes too severe. Solutions for this issue are complicated, but not to us. Carolina Foundation Solutions is a family-owned and operated foundation repair company specializing in a wide array of foundation solutions. One of these solutions being Polyurethane Foam Injection.

What do the experts at Carolina Foundation Solutions say causes settlement?

As previously stated, every home, old or new, experiences some form of settlement over time. Settlement is due to the surrounding soils underneath your home. Think of it as your home settling in and getting used to the location. As the house settles, it starts to rely more on the soil underneath for support. A common cause of excessive settling is voids. Voids are pockets of space between the bottom side of the concrete slab and the ground underneath. These pockets of space vary in size and cause your concrete slab to compensate for the lack of support by sinking, searching for the soil beneath. Think of it as your home trying to compensate for what should be there. Another common cause of excessive settling is due to poor underlying soil conditions. Poor soil conditions result from the layer of topsoil being too weak to support the weight of your home. At this point, this is when a polyurethane foam injection is needed.

What is a Polyurethane Foam Injection?

The polyurethane foam-injection grouting procedure is a type of pressure grouting performed like other grouting but:

  • Creates less mess
  • Requires less material curing time
  • It can be done by drilling much smaller holes

With this type of foundation slab repair, we drill holes through the concrete slab. Then, we inject an Alchemy Polymers polyurethane foam product into the holes. This product is a two-component, high-strength, hydro-insensitive structural polymer foam.

The material is lightweight and provides immediate results that:

  • Fill any voids that may exist between the bottom of the concrete slab and the top of the soils
  • Consolidate loose and soft soils located next to the upper layers of the underlying soils
  • Create a more solid base for the slab to prevent further movement in the future

In other words, this foam expands once injected and lifts the settled concrete back into place and then hardens to create a solid base for the concrete slab and hinder any future movement that may occur.
