Before and After
  • PolyLEVEL for House on Slab - Hampton, NH

    PolyLEVEL for House on Slab - Hampton, NH

    This home in Hampton, NH was built on a slab, which over the years was gradually settling. PolyLEVEL was an ideal solution to lift the slab and fill the voids underneath, while doing minimal damage to the inside (holes drill through the slab). The slab had settled up to an inch, putting the floor out of level, and PolyLEVEL easily lifted it back into a level position.

  • Raising Interior Concrete Slab, Holden, MA

    Raising Interior Concrete Slab, Holden, MA

    This homeowner in Holden, MA was very concerned with the interior concrete slab in their mudroom entrance area. The concrete had settled significantly, leading to large cracks in the surface, and making it impossible to remodel the space. It was also unsafe and likely to get worse as the slab continued to settle. 

    Rather than demolish the entire slab (dirty and costly), the owner sought out an alternative way to solve the problem, which he found in PolyLevel. 

    Our team installed the injection foam and not only stabilized the interior slab, but lifted it up several inches in some locations. With the dangerous voids beneath the slab now filled, the homeowner continued with their remodel project.

    Water Entering Garage From Driveway, Lexington, MA

    This homeowner in Lexington, Massachusetts recently purchased her childhood home. She is planning on doing manageable renovations to increase the value of the home. She had completed a couple of renovations already but now has started working on the garage. Water from the driveway has been entering the garage and has caused some damage. She decided to call EFS for a free inspection. 

    Design Specialist Brian Swindell inspected the foundation and garage of the home. Brian discovered that there is some void below the slab in the garage that he recommend filling before attempting to lift the slab. To help stop the water from entering the garage Brian recommended installing Trench Drain at the mouth of the garage with a downspout. 

    Crew Lead Nick Melo and his team lifted the mouth of the garage to level and then filled the void under the slab. After the PolyLevel was injected, the team installed the Trench Drain at the mouth of the garage.

    Settling Home on Slab

    This home in Danvers, MA was built on a slab. Overtime, water caused soil under the slab to erode, creating voids. The homeowners were preparing for a remodeling project and noticed the slab had settled 2-3 inches in some places, and so needed to be raised again. Erickson Foundation Supportworks installed PolyLEVEL to stabilize the slab.

What causes uneven floors in a home?

Concrete slabs are often poured on wet, weak, or poorly compacted soil. Over time, this will lead to settlement of the slab, causing uneven floors or cracking. Inside your home, your floor will pull away from walls and doorways, creating gaps at the seams.

This not only creates an uncomfortable home with tripping hazards, it also significantly impacts property value. When prospective buyers have to deal with foundation issues, it can make selling a home very challenging.

How we repair sunken interior slabs with PolyLevel®


There are several traditional methods of raising concrete slabs, including spreading self-leveling compounds, mudjacking, and pier installation. However, these methods can be very invasive and often don't fix the source of the problem.

PolyLevel® is the solution to these problems. This is how the PolyLevel® system works to raise your sunken slab:

  • Very small sections of existing finished flooring are removed to access slab
  • Penny sized holes are bored into the slab in each affected room
  • Polyurethane foam is injected through holes, where it expands and raises the slab
  • Foam is injected until the floor is level, reaching 90% rigidity within 30 minutes
  • Finished flooring is restored over injection holes

With our system, you get the best solution for sunken concrete available without creating significant upheaval in your home.
