Concrete Stabilization

What is Concrete Stabilization?

  • Concrete stabilization is just as it sounds, it’s the process of making concrete physically more secure and stable. Over time due to several factors, the ground concrete is resting on can become undermined. While this normally happens slowly over time, it can have a rapid effect depending on the cause of the undermining. If it is dealt with before the soil bed is too damaged, we are able to stabilize instead of lift your concrete slab. We use the same process as concrete lifting and with less foam so it does not actually lift the concrete. We simply inject the foam under the slab, and as it expands, it will compact the soil below and stabilize your concrete. This process can be performed as many times as necessary to achieve the desired outcome.

How Does it Work?

The process is simple, painless, and quick. After a site survey from one of our professionals to determine the potential causes of the undermined soils, our crew will come out and follow the steps below to stabilize the concrete. 

When May Concrete Stabilization be Needed?

Concrete stabilization is needed when you begin to see hairline cracks in your concrete. The cracks generally indicate the soil beneath the slab has been compromised in some way and there are voids forming. We can inject our polyurethane structural foam in these voids to recompact the soil, and give the concrete slab the stability it needs to last you a lifetime. 

Application Types

  • – Undermined buildings
  • – Compromised houses
  • – Eroded patios, sidewalks, and driveways
  • – Weakened roadways
  • – Damaged manholes

 

Undermined Slab Process

Step 1

  • Drill a 3/8 inch hole where the foam needs to be injected

Step 2

  • Pump the foam under the slab though the 3/8 inch hole and watch the dial gauges for confirmation that the soil has been compacted. Once we see the slab begin to move .001 of an inch we know the soil is stabilized
  •  

Step 3

  • Patch the holes so water can not undermine the foam

Step 4

  • Rest easy knowing that you’ve extended the life of your concrete for years to come

Deep Lock Stabilization

  • Sometimes the voids are larger and deeper in the soil. When this is the cause, we offer “Deep Lock” stabilization. This works by driving thin long pipes into the ground to inject the foam at the lowest point of the disturbed soils.

Process

Step 1

  • Determine depth of void

Step 2

  • Perform soil test to determine the correct chemical needed for the job

Step 3

  • Plan out a grouting layout for deep lock stabilization

Step 4

  • Layout the grout layout and drive the steel rods into the ground

Step 5

  • Begin to pump the desired amount of foam into the soil at predetermined rate

Step 6

  • Rest easy knowing you are back on stable ground
