Polyurethane lifting or foam jacking typically offers a more durable repair. Also, it’s less invasive and doesn’t require the same curing time. On the other hand, mud jacking is typically less expensive. It’s a good choice for those on a budget or who need a quick fix before selling.

Mud Jacking vs. Foam Jacking - How Do They Compare?

To better understand mud jacking vs. foam jacking as a type of house foundation leveling, it’s helpful to review each method in detail. First, note that both processes lift concrete slabs. Second, remember that your repair contractor can offer more information about what’s best for your property!

What is mud or slab jacking?

For a mud jacking process, a contractor first mixes sand, cement, and aggregate to form a slurry. Next, they drill holes through uneven concrete slabs. Then, your contractor injects the slurry under the concrete slab.

This slurry then “floats” the concrete back into position, eventually drying and hardening. A contractor can use this process for slab foundations, driveways, walkways, and other installations.

What is foam injection?

Foam jacking uses materials similar to spray foam insulation called polyurethane. First, a contractor drills small holes through uneven, existing concrete slab. Second, they use specialty hoses to spray the polyurethane foam through the hole and under the sunken concrete slab.

As expected, the foam then expands and lifts the concrete into position. In fact, foam jacking material can expand up to 7 feet for every injection port! The foam hardens as it dries, keeping the concrete level.

Which Is Better, Mud Jacking vs. Foam Jacking?

Both mud jacking and foam jacking are excellent repair choices, and neither is “better” or the best method. While a foundation repair contractor can offer added advice, check out some pros and cons of both processes.

Mud or slurry - Pros & Cons

First, mud jacking is usually cheaper than foam jacking, as said. Second, it’s easier to control the slurry than expanding foam. In turn, it’s often better for jobs requiring more precise filling.

On the other hand, mud jacking requires larger openings or holes. Consequently, weeds might grow through those holes over time. Also, a contractor usually needs more cleanup time for mud jacking. Lastly, mud slurries usually require a full day for curing and drying.

Foam jacking or Polyurethane concrete lifting- Pros & Cons

A contractor needs smaller injection ports for foam jacking, often no larger than a penny. There is less risk of weed growth or water seeping through those ports after the foam is pumped beneath concrete slabs. Also, the expanding foam can reach areas that mud slurries cannot!

Additionally, poly foams dry in about 15 minutes or so. As a result, you can use driveways and walkways far sooner after repairs than if you chose mud jacking. Lastly, note that foam jacking seems to last longer than mud slurries. In turn, it’s often a better long-term investment for homeowners.

On the other hand, some homeowners might want a quick, inexpensive fix for homes they might put on the market. In that case, mud jacking is often a better value for a sunken concrete slab.

Does Foam Jacking Work for a Concrete Slab Foundation?

In short, foam jacking is an excellent investment for a sinking foundation. The foam is durable and able to lift heavier structures, including slab foundations. Also, since contractors can control foam easily, it means less risk of concrete damage. Smaller hoses for injection also allow them to reach areas under a structure not suitable for mud jacking.

When Should You Schedule Concrete Repair?

Call a concrete repair contractor when you notice cracks larger than 1/4” wide. Also, stairstep cracks along brick exteriors or basement walls usually need prompt fixing. Inside a structure, you might notice dampness or even standing water. This typically indicates cracks large enough to let excess moisture into interior spaces.

Above all, consider concrete repair if damage poses safety risks. For instance, cracked or chipped sidewalks often mean hazards for foot traffic. Cracked basement walls might make it easier for someone to pry open a basement window! In those cases, it’s vital that you schedule prompt repairs.
