USE SECURE SET FOR SLAB JACKING AND LEVELING CONCRETE SLABS

Slab Jacking With Secure Set

Slab jacking, also known as mudjacking or concrete leveling, is a repair technique used to lift and level sunken or uneven concrete slabs.  Secure Set Spray Foam is ideally suited for this purpose.  Here’s a simplified overview of the process:

  1. Access Holes: Small holes are drilled into the affected concrete slab with a 3/8″ masonry drill bit.
  2. Material Injection: Secure Set Spray Foam is injected into the holes.
  3. Lifting: As the Secure Set expands, the slab slowly lifts. Caution, patience, and finesse are needed.  Do not over inject.  
  4. Hole Sealing: Once the slab is level, the holes are sealed, and the surface is cleaned up.
  5. Curing: Secure Set solidifies and hardens quickly, stabilizing the slab and the ground beneath it.

Videos showing how to use Secure Set Spray Foam

There are many situations where Secure Set Spray Foam can be used to raise and level concrete.  We frequently receive questions asking if it can be used for this project or that project.  In almost all cases the answer is yes. 

The common denominator is a situation where a concrete pad is no longer level in one or more areas.  It could be in a corner, along an edge, or something similar. 

The videos below demonstrate two cases where Secure Set Spray Foam was used to level a slab of concrete.  We encourage you to watch both as there are similarities and some unique elements to each project which can apply to many other projects as well.

DIY Slab Jacking with Secure Set

Our customers do their research and often compare bids from contractors to rip out and replace a concrete slab or level it with other methods before deciding to use Secure Set on their own. 

Two things stand out as factors when choosing to do it themselves: 

  1. Cost – Using Secure Set often saves them several thousands of dollars.
  2. Time – removing and replacing a slab takes time and renders the area unusable for several days while the concrete cures.

Here’s what Mario G. told us about his experience with Secure Set Spray Foam

“The foam kit worked well. I raised a 9’x 14′ concrete slab 1″ and two corners 1/4″. Also filled voids under 2×4 wood break joints. Great product!”

Ray W. had this to say about Secure Set Spray Foam for Slab Jacking

“I had used Secure Set Spray Foam to raise and level the back porch slab, sidewalk going to the front door, and the driveway. The driveway has 9 sections 10feet X 10feet square over 11 inch thick,  I found out after drilling. NOW all of the slabs are level, the sidewalk is level and the back porch has returned to original position. I would recommend this product. Easy to use, easy cleanup. About a third the cost of 4 other company’s I had called to do the leveling for me.
Thanks Secure Set!”

What Causes Concrete Slabs to Sink

Sunken or uneven concrete slabs can be caused by a variety of factors. Here are some of the most common causes:

  1. Soil Erosion: Water can wash away soil beneath a concrete slab, creating voids. Over time, the slab may sink into these voids, leading to uneven surfaces.
  2. Soil Compaction: If the soil wasn’t properly compacted before the concrete was poured, it could settle over time under the weight of the slab, causing the slab to sink.
  3. Soil Shrinkage: In some cases, the soil beneath a slab can shrink due to drying out, leaving voids under the slab. This is common in areas with clay soil, which can expand when wet and shrink when dry.
  1. Tree Roots: Tree roots can grow beneath a slab, pushing it upward or removing soil and causing it to sink.
  2. Freeze-Thaw Cycle: In colder climates, the freeze-thaw cycle can cause the ground to expand and contract, leading to movement of the slab.
  3. Poor Drainage: Inadequate drainage can cause water to pool under a slab, eroding the soil and creating voids.
  4. Plumbing Leaks: Water from plumbing leaks can erode or wash away the soil beneath a slab, leading to sinking or settlement.

By identifying and addressing the underlying causes of slab settlement, homeowners and property managers can prevent further sinking and the need for slab jacking or other corrective measures.

Are there situations where I should not try to slab jack with Secure Set?

If the concrete pad that is unlevel is old and flaking and/or broken in several areas, you may be better off removing and replacing the pad and addressing the underlying cause of erosion.  Trying to lift multiple pieces of concrete with spray foam could produce inconsistent results.
