"Excellent professional job. Hector and his crew demolished an old crooked concrete block wall and rebuilt a new sturdy one with rebar and footings. The team then stuccoed and painted the wall and it is beautiful! The job site was kept as clean as possible during and after the project. I would highly recommend Block-Crete Construction!"

"Top notch work. I'm a homeowner building in Burbank. I received 4 other estimates and spoke to many people. I needed 150 sheets of drywall installed and finished- this was by far the most drywall I ever needed. After meeting Ciro, I felt comfortable and had a very positive feeling about his character. He quoted a fair price and we finalized the job that day. They did a level 5 finish in the living room, kitchen and baths. It's the first time I ever had level 5- the walls are perfectly smooth from floor to ceiling. I'm very happy with the results. Thank you Ciro."

"Nexxus did a fantastic job, in February of 2022, removing sidewalk, concrete stairs and driveway, replacing the houses water supply, forming and placing new concrete, including iron work for a new custom gate and handrail. Tony was the quickest contractor I’ve ever worked with. They were ready to work within a few days of original contact and completed at least a month’s worth of work in one week."

"Mr. Parks and his workers were thorough, polite and efficient. My gutters were full and badly clogged because of several years of neglect. They removed all debris from my roof and dug out the gutters by hand until they got water freely flowing through the downspouts. It was a positive experience from beginning to end."

"They did an amazing job! The driveway came out amazing as well as the process was easy and non disruptive. They were very nice and easy to work with with and the final product came out outstanding.

Thank you guys very much for the work."

Concrete Leveling questions, answered by experts

Concrete leveling is not typically covered by insurance. In some cases where the shifting concrete is caused by a natural disaster or storm, you may be able to file an insurance claim if your policy specifically covers those circumstances. In most cases, though, you’ll pay out-of-pocket for concrete leveling.

Mudjacking typically takes 24 to 72 hours (one to three days) to dry and cure completely before you can resume normal use. The exact time can vary depending on the size of the project. Because the slurry mixture contains cement, it must fully harden to ensure that added weight from walking, furniture, or vehicles won't shift the concrete slab. A professional contractor can advise you on when the surface is safe to use. For comparison, if you use polyjacking instead, the polyurethane foam can dry in just a few minutes, but it's best to wait about an hour before use.

The polyurethane used for polyjacking will expand and cure in 15 to 30 minutes. After that point, your slab will be safe to walk on and even drive on in the case of a sidewalk or concrete driveway. Double-check with your concrete lifting specialist to confirm a curing timeline, as products can differ.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

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.
