"The crew that came to my home worked for three days in my crawl space repairing support beams and pouring new concrete piers. They worked efficiently, they were professional, and knowledgeable, and I really can not complain about anything. They also took before and after pictures of my crawl space."

Concrete Leveling questions, answered by experts

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The total drying time can vary depending on the size of the project. Because the slurry mixture contains cement, it needs to harden fully to prevent the concrete slab from shifting under added weight. You should avoid walking on the concrete or placing heavy items like furniture or vehicles on the surface until it has fully set. Your concrete contractor can provide a precise timeline. As a point of comparison, if you opt for polyjacking, the polyurethane foam can dry in minutes, but it's recommended to wait about an hour before use.

Mudjacking restores level surfaces, prevents further damage, and is more cost-effective than a full replacement.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

Concrete leveling can last anywhere from five to 10 years or more, and in some cases, it can be a permanent solution. The longevity depends on the method used and whether the underlying cause of the sinking is addressed. For example, mudjacking typically lasts five to 10 years, while polyjacking can last for 20 years or more. It's best to consult a professional for an accurate timeline based on your specific situation and any factors that could cause the issue to recur.

Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.
