Why Deep Foam Injections Are Superior to Mudjacking

For many decades, mudjacking was the preferred option for leveling concrete without the need for replacement. It has been used for over 75 years and does provide an excellent alternative to tearing up and replacing unlevel walkways, driveways, patios and other concrete slabs. But like most inventions, there is always something better that comes along. For mudjacking, the superior alternative is deep foam injections.

Similarities Between Mudjacking and Foam Concrete Leveling

The concept behind both mudjacking and deep foam injections is the same. Instead of removing and replacing sunken concrete, the slab is lifted from underneath by pumping a substance/filler into the soil under the concrete. Mudjacking uses wet cement that is pumped under the slab, lifting it up, then curing into a hard layer to support it. Deep foam injection uses a lightweight polyurethane foam blend that does the same thing, supporting and lifting the slab from underneath. But that is where the similarities end.

Advantages of Deep Foam Injections vs Mudjacking

While both mudjacking and deep foam injections can achieve the same results, there are significant differences between the two methods. The filler that is pumped under the concrete is different and so is the method and curing process. Some of the advantages of deep foam injection versus mudjacking include:

  • Lightweight foam does not have the heaviness of cement. Per cubic foot, cement weighs 30-40 times the amount of the polyurethane foam blend.
  • The holes drilled into the concrete for foam injections are only 5/8” wide, much smaller than those needed for mudjacking. This means smaller patchwork to fill the holes.
  • Curing time for polyurethane foam is only about 15 minutes. Cement can take up to two days to completely cure.
  • Concrete can be used the same day after deep foam injection leveling, unlike mudjacking, which takes a few days before concrete can be used.

When you have a patio, walkway, driveway, pool deck or other concrete slab that is sunken, deep foam injections offer a superior alternative to mudjacking for leveling. To learn more or get a quote, contact our team at Advance Concrete Lifting and Leveling in Atlanta, GA.
