Polyurethane Foam Lifting: Bringing Sunken Concrete Back to Level
Polyurethane foam, also known as foam jacking, is the other option for lifting sunken concrete and filling voids, compared to traditional mudjacking. This system is ideal for use in situations such as inside finished buildings or confined areas. 5/8” holes are drilled into the concrete slab, where polyurethane resin is injected under pressure. This resin expands beneath the slab, filling voids and lifting it. Once the process is complete, the injection holes are filled, and the area is ready to be returned to service almost immediately, usually within 15-20 minutes.

What is Polyurethane Foam Concrete Leveling?
Polyurethane foam concrete leveling is an innovative solution for lifting and leveling sunken or settled concrete slabs. This method utilizes a lightweight, ultra-strong, and waterproof polyurethane foam. The process begins by drilling small holes into the top of the concrete slab. The polyurethane foam is injected through these holes, where it expands to fill any voids beneath the concrete. This expansion effectively lifts and stabilizes the slab, restoring it to its original level. Polyurethane foam concrete leveling is not only cost-effective but also eco-friendly and long-lasting, making it an ideal choice for addressing issues with settled concrete.
How Does Foam Concrete Leveling Work?
Foam concrete leveling operates through a straightforward yet highly effective process. Small holes are drilled into the top of the concrete slab, and a specialized high-density polyurethane foam is injected through these holes. As the foam expands, it fills any voids beneath the concrete, lifting and stabilizing the slab. This method is efficient, with most repairs completed within just a few hours. The high-density polyurethane foam used in this process is specifically designed for concrete lifting and leveling, ensuring a durable and stable result.
The Benefits of Polyjacking
Polyjacking is a cost-effective and eco-friendly option to stabilize existing concrete slabs. Polyurethane foam has many advantages compared to other concrete levelling methods. Get in touch with our team today for polyjacking services in Edmonton. The advantages of polyjacking are:
- Cost-effectiveness: Polyurethane foam is a budget-friendly solution, often costing less than half the price of laying new concrete.
- Eco-friendliness: This method is environmentally friendly and does not harm the surrounding soil or environment.
- Minimal disruption: The process is minimally invasive, causing little to no disruption to daily activities.
- Long-lasting results: With proper maintenance, polyurethane foam provides durable results that can last for decades.
- Versatility: Suitable for both commercial and residential projects, polyurethane foam can lift building structures and fortify compromised base soils.
- Water Repellant: Polyurethane foam is water-resistant, crucial for commercial uses to prevent water damage, ensure concrete’s structural integrity, and increase its lifespan.
- Lightweight: Polyurethane foam is lightweight, preventing added soil pressure and destabilization, yet offers strong lifting capabilities for stable concrete support.
- Extreme Concrete Lifting Capability: Polyurethane foam is lightweight, which helps prevent soil stress, while its strong lifting capacity ensures stable concrete stabilization. prevent soil stress, while its strong lifting capacity ensures stable concrete stabilization.
Polyurethane Foam vs. Mudjacking
Each method has pros and cons when comparing polyurethane foam and mudjacking for concrete leveling and lifting. Polyurethane foam is generally considered more durable and lighter than mudjacking. It also cures faster and is less invasive, making it a preferred choice for many projects. However, mudjacking is typically about 20% less expensive due to lower material costs. Despite the higher initial cost, the long-term benefits of polyurethane foam, such as its durability and minimal disruption, often make it a more cost-effective solution in the long run.
Factors Affecting Concrete Slab Lifting Costs
Several factors can influence the cost of concrete slab lifting:
- Square footage of the concrete slab: Larger slabs require more material and labour, increasing the overall cost.
- Degree of settlement: More severe settlement necessitates more material and labour, which can drive up costs.
- Complexity of the job: Jobs that require specialized equipment or techniques can be more expensive.
- Type of polyurethane foam used: High-density polyurethane foam is more costly than lower-density options.
- Labour costs: These can vary based on the contractor’s location, experience, and reputation.
It is essential to get a personalized assessment and detailed quote from a qualified contractor to accurately determine the cost of your project.
