A Deep Dive Into the Durability of Concrete Repair Foam

If you’ve noticed sinking concrete around your home or business—whether it’s a driveway, sidewalk, or basement floor—you may be considering foam jacking to fix the problem. But one of the most common questions we hear at Sealtite Insulation & Slabjacking is: “How long does foam jacking last?”

Let’s break down the science behind concrete repair foam, why it works so well, and how long you can expect your lifted concrete to stay in place.


What is Foam Jacking?

Foam jacking, also known as polyurethane concrete lifting, is a modern solution to concrete settlement. It involves injecting high-density polyurethane foam beneath the surface of a sunken concrete slab. As the foam expands, it fills voids in the soil, compacts loose ground, and lifts the slab back into place.

At Sealtite, we exclusively use professional-grade concrete repair foam because of its proven durability, quick curing time, and long-term performance.


So, How Long Does It Last?

The short answer? Foam jacking can last for decades—and in many cases, the repair lasts as long as the original concrete slab itself.

Here’s why:

  • 🧱 The foam is permanent: High-quality polyurethane foam is waterproof, resistant to erosion, and does not break down over time.

  • 🌧️ It won’t wash out: Unlike traditional mudjacking, polyurethane doesn’t absorb water or erode with rainfall and flooding.

  • 🪨 It strengthens the soil: As the foam expands, it compresses the soil, creating a more stable base and reducing the chance of future settlement.

  • 🧪 Chemically stable: Concrete repair foam doesn’t react with soil, moisture, or air—once it’s cured, it stays exactly as it is.


What Can Affect the Lifespan?

While the foam itself is designed to be permanent, external factors can affect how long the lifted slab stays level:

  1. Soil Conditions: If the ground beneath the slab continues to shift or erode due to water flow or poor drainage, further settlement could occur.

  2. Heavy Loads: Repeated heavy traffic or large machinery can stress the slab and the soil underneath.

  3. Poor Drainage: Water pooling near your slab can lead to future voids. After foam jacking, it’s a good idea to correct any drainage issues to extend the life of your repair.

The good news? When installed correctly by professionals, and with proper site conditions, foam jacking offers a long-lasting fix to concrete settlement.


Foam Jacking vs. Mudjacking: Which Lasts Longer?

Foam jacking outperforms mudjacking in durability every time. While mudjacking uses a slurry mixture that can eventually wash out or erode, concrete repair foam is waterproof, lighter, and creates a permanent bond beneath the slab.

It also cures within minutes, minimizing disruption and making it ideal for residential and commercial applications alike.
