Top 5 Customer Questions About Slab Leveling

Just like with any construction project, customers are going to have several questions to help them understand how their project is going to go and what to expect from their contractor of choice. This is no different when trying to determine if polyurethane is the right solution for their concrete lifting project. Here are a few routine questions that customers have when evaluating the slab leveling process. 

1. How does slab leveling with polyurethane work? 

Slab leveling with polyurethane is actually a rather simple procedure. Polyurethane is a specialized geotechnical system that is formulated to densify soil with enough expansive potential to lift and level concrete. When the polyurethane is injected below the concrete, it helps to re-establish the load of the slab back into the soil. It then expands to the point where it creates an upward lift. 

2. Does polyurethane slab leveling require excavation? 

No excavation is necessary when it comes to slab leveling. The process begins by drilling 5/8″ holes, less than a penny, through the slab to give access to the area underneath the slab. Polyurethane is then injected into these access points. The holes are then covered up with a cement grout. This helps deal with any aesthetic issues. 

3. How long does polyurethane slab leveling take? 

Slab leveling with polyurethane is a fast process. Geotechnical polyurethanes range in expansion and cure time, but they typically cure up to almost one hundred percent capacity within a half hour or so. You’ll be driving over the affected area in no time. The actual project length is dependent on the size and scope of your project, but typically a standard residential project can last anywhere from two to eight hours from start to finish. 

4. Does polyurethane harm the environment? 

Our geotechnical polyurethanes are environmentally inert, which means they do not leak chemicals into surrounding soil or water. In specialized formulations, our polyurethanes meet NSF-61 ANSI safe drinking water standards. This means that the polyurethane can be put in contact with drinking water without concern for contamination. 

5. What is the cost of polyurethane slab leveling? 

Polyurethane slab leveling costs are entirely dependent on the size of your particular project. However, when compared to the cost of full slab replacement, polyurethane slab leveling is significantly less expensive. Additional costs that need to be considered are costs of time, to excavate the problem area, and the chance of losing access to your structure over a period of time.
