"This is the third project that EA Masonry has completed for us and as the other two projects went, this was top notch as expected. Dan and his guys demo’d a huge, old concrete patio and stairs along with clearing out numerous overgrown bushes. They installed a new patio and walkway along with two sets of entry stairs. The craftsmanship from EA Masonry is incredible and we recommend them to everyone we know who needs any type of masonry work done. You will not be disappointed."

"I got great service from Erickson. Nate Erickson was very responsive and spent a lot of time with us answering all of our questions. Although we did not decide to go with Erickson for our work, I would highly recommend them for their knowledge and customer service."

"It went very well! Found CF Masonry via Google and Angi searches and was so glad that I did! After meeting with Carlos, the owner, and receiving a quote later that same day, we agreed to move forward. Carlos did a BEAUTIFUL job adding granite and stone to the outdated cement landing outside of our front door. I wasn’t sure exactly what I wanted and after showing him a picture I left it up to him to execute his vision. I absolutely love the results! I found Carlos to be reasonably priced, professional, dependable and meticulous in his work. I would not hesitate to use him again- he is a true craftsman. Thank you, Carlos!"

"This was two-man job over three days, building a 160 sq ft level patio in sloping terrain. They did an excellent job, overcoming the challenges posed by the terrain, and ending up with a beautiful patio that looks better than I imagined."

"I contacted Paul through Angie's List on Monday. He called the same day, and we made an appointment for Tuesday. I had thought that we were just going to get a quotation for the job, but Paul and his co-worker were ready to do the job. They arrived when he promised, gave me a very fair price for the job and had the 100 foot driveway sealed beautifully in less time than I expected. It looks great. Yes, I recommend this company."

"When I first met Stavros, he discovered damage that another company completely missed. His inspection was thorough and he explained the situation so we could easily understand what was happening and what we needed to do to repair it. He and his crew then did a very thorough job repairing our concrete foundation that had cracked and was sinking due to problems with the subsoil, as well as leveling the concrete slab in our basement. He took care not to damage our property, and even maneuvered his equipment under our deck so we didn't have to remove it to complete the repair. He and Athena genuinely care about their customers, and were empathetic and kind throughout what was a difficult experience for us as homeowners. I would not hesitate to recommend Arta to anyone who needs foundation work."

Concrete Leveling questions, answered by experts

Polyjacking and mudjacking can both be effective solutions for sinking concrete, but they have key differences. Polyjacking, which uses expanding polyurethane foam, is often considered a better option because the foam is significantly lighter than the cementitious material used for mudjacking. This reduced weight puts less pressure on the underlying soil and lowers the risk of future sinking. Polyjacking is suitable for any sinking concrete slab, while mudjacking is typically only recommended for non-structural concrete, such as sidewalks, patios, pool decks, and driveways. The primary drawback of polyjacking is its cost, which can be up to four times higher than mudjacking—as much as $25 per square foot compared to a maximum of about $6 per square foot for mudjacking.

A slurry of cement, sand, and water is injected beneath the concrete to lift and stabilize it.

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.

Yes, you can mudjack cracked concrete, but the cracks will need to be repaired once the concrete has been leveled. If the concrete is severely cracked in multiple places, replacement may be a better option, but for less severe cracking, mudjacking is a good solution as long as cracks are correctly caulked and sealed.

The timeframe is generally a few hours, allowing for immediate use post-hydration, ensuring minimal disruption to surrounding activities.
