"When I was getting bids for our paver project, one of the three bids I got was from Rios Brick Pavers. I asked Mauricio, the owner, why I should hire him. Without hesitation, he responded, “Because of the quality of our work.” He went on to say that his crew is great at what they do, and they have been with him for many years. He told me that there may be some competitors who will offer a lower price, but none will match his quality workmanship. Mauricio and his crew went on to deliver on his promise. We had walkways, a large gravel area, and a brick patio integrated into a beautiful and welcoming space that greatly enhances the usability and the look of our home. We could not be happier with the quality of the work and the finished look of the paver project. Mauricio was excellent on communicating status throughout the project. As there are with any project, there were a couple of unexpected challenges that he let me know about right away. The solutions he developed provided additional proof of the experience of his crew. Finally, it should be noted that his team began the project on schedule and finished a day early. I give Rios Brick Pavers my highest recommendation. Quality work at a fair price. Beautiful result."

Mudjacking and foam jacking differ significantly in both materials and methods. Mudjacking uses a cement-based slurry to fill voids beneath a slab, while foam jacking uses expanding polyurethane foam delivered under high pressure to achieve superior structural support. This material distinction enhances load-bearing strength and overall stability in your repair.
Mudjacking takes between one and three days to dry completely. During this time, it's important to avoid putting weight on the slab until it's fully cured. The drying time depends on the project size and environmental conditions. In contrast, polyurethane foam used in foam jacking can cure in as little as one hour.
No, mudjacking is not a permanent fix for sinking concrete. While it effectively lifts the slab and can last five to 10 years, it doesn't address underlying soil issues that may cause future sinking. For a more permanent solution, you might consider foam jacking or complete slab replacement, which can address deeper structural problems.
