Foam jacking, also known as polyurethane foam injection, is a modern method used to lift and level sunken or uneven concrete surfaces. This technique involves injecting expanding polyurethane foam beneath concrete slabs to fill voids and raise the surface to its original position. It is commonly used for driveways, sidewalks, patios, and even warehouse floors. Known for its precision, speed, and durability, foam jacking is a clean and efficient alternative to traditional concrete replacement methods.

🧪 Lightweight Yet Powerful

Polyurethane foam is extremely lightweight compared to traditional cement-based slurries, reducing the risk of further soil compression beneath the slab. This makes foam jacking ideal for areas with poor soil conditions or unstable subgrades. Despite its light weight, the foam expands with enough strength to lift thousands of pounds of concrete. This helps ensure long-lasting results without adding extra stress to the ground.

⚡ Fast-Acting and Time-Saving

Foam jacking sets and cures quickly, with most surfaces ready for use within just 15 to 30 minutes after application. This is significantly faster than traditional mudjacking or concrete replacement, which can take several hours or even days. Quick cure times mean reduced downtime for homeowners, businesses, or public walkways. It’s an ideal solution for projects requiring immediate usability.

🌦️ Weather Resistant and Waterproof

The closed-cell structure of polyurethane foam makes it resistant to moisture, making it perfect for environments exposed to rain, snow, or groundwater. Unlike mudjacking materials, foam doesn’t absorb water or degrade over time. This helps protect the foundation and surrounding surfaces from water-related damage. It also supports long-term stability by resisting erosion.

🔍 Precise and Controlled Lifting

Foam jacking allows for highly accurate adjustments, making it especially valuable for projects requiring precision leveling. Contractors can monitor foam expansion in real-time and stop injections at the exact right height. This minimizes the risk of over-lifting and delivers consistent, even results. It's particularly beneficial for slabs supporting structures like walls or equipment.

♻️ Environmentally Conscious Option

Because foam jacking avoids the need to demolish and dispose of existing concrete, it helps reduce landfill waste and construction debris. Polyurethane foam is also inert and non-toxic once cured, posing minimal risk to the surrounding environment. It’s a sustainable option that supports green building initiatives and long-term environmental health.

📉 Long-Term Cost Efficiency

Although the initial cost of foam jacking can be higher than mudjacking, its durability and minimal maintenance needs make it cost-effective over time. According to industry reports, foam jacking can last 10 to 15 years or more under normal conditions. Its resistance to moisture, shifting, and shrinkage helps avoid repeat repairs, offering peace of mind and value for your investment.
