When it comes to fixing sunken or uneven concrete slabs, homeowners have two main options: slab jacking with polyurethane and mudjacking (lifting with cement slurry). Both methods aim to level the slab without demolishing or replacing it. However, they differ in their approach and effectiveness.

What is Mudjacking?

Mudjacking involves pumping a mixture of cement, water, and other materials (known as "mud") under a sunken slab to raise it. This process has been around for over 60 years. While it can lift settled concrete, it has some drawbacks.

The weight of the mud material can be as much as 100 lbs per cubic foot, which can cause further settlement. Moreover, mudjacking requires drilling 2-3" holes in the concrete to pump the thick material through. These holes need to be patched and can be noticeable. Additionally, the mud pumped under the slab takes a lot of time to cure, sometimes up to a couple of days.

Benefits of Polyurethane Slab Jacking

• Lighter Weight: Polyurethane weighs only 2-4 lbs per cubic foot. This lightweight material helps stabilize the soil without adding extra weight that could cause further sinking. Furthermore, polyurethane expands to fill voids and crevices, providing excellent support.
• Smaller Holes: Polyurethane injection requires only 3/8" holes, which are much less noticeable when patched. This results in a cleaner and more aesthetically pleasing repair. 
• Faster Curing Time: Polyurethane cures quickly, reaching up to 90% full strength in just 15 minutes. This means the slab can be used almost immediately after repair. 
• Less Disruption with Minimal Equipment: Polyurethane slab jacking requires less heavy equipment compared to mudjacking, resulting in minimal disruption to the surrounding property. The process is less intrusive and can be completed more efficiently, causing less inconvenience to the homeowner.
• Permanent Bonding: Polyurethane forms a strong, permanent bond with the underside of the concrete slab. This creates a secure, long-lasting solution that effectively supports the slab and prevents future settling or sinking.
• Water Resistance and Erosion Prevention: Polyurethane is water-resistant, which helps prevent further erosion of the soil beneath the slab. By sealing out moisture, polyurethane minimizes the risk of future settling caused by water-related issues, ensuring a more stable and durable repair.

Considering these advantages, polyurethane slab jacking is optimal for most concrete leveling situations. Its durability, effectiveness, and ease of application make it the go-to solution. When considering slab jacking, homeowners should seek a qualified, experienced contractor to ensure the best results.

Lifting Concrete with Precision

When faced with sunken or uneven concrete slabs, slab jacking with polyurethane offers a more effective and long-lasting solution compared to mudjacking. Its lightweight properties, smaller application holes, and faster curing time make it an efficient choice for homeowners. By opting for polyurethane slab jacking and working with a reputable contractor, homeowners can successfully restore their concrete surfaces to a level and stable condition while avoiding the potential drawbacks of mudjacking.
