"Angel and Andrew did a great job on raising the concrete on my patio. One side was sinking which caused the other side to lift up. They were able to even out the cement so now it looks great. Thank you for working so hard to fix it."

"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!"

"I called CXC Contracting because I had noticed uneven floor in one room of the house. Will Crawford inspected the concrete slab under the floor and performed accurate measurements of the house leveling inside and outside the house. Despite the uneven floor, he concluded that the house did not need any foundation repair and that the uneven floor was caused by imperfections of the concrete.slab. He spent a lot of time in my house and provided an objective assessment of the house foundations not influenced by considerations of personal advantage. He provided unbiased recommendations about how to improve the floor leveling. I was very impressed by his professional ethics and technical knowledge. I will certainly trust Will in the future and I recommend him to anybody.

"I had just purchased a new town home in Santa Fe Springs that came with a plain concrete slab in my rear yard entertaining area. I wasn't happy with the look and decided to give Martin from Pacificland Constructors a call since he had done work on other rental properties I own.

I told Martin that I wanted a new stamped concrete patio slab for my rear patio area. For our initial estimate meeting Martin came with several brochures from the different concrete colors available and stamp patterns for me to keep and help with my decision making. He explained the whole construction process. I felt very comfortable with Martin due to his honesty, professionalism, and his design help.

I decided to move forward with the job and it came out great. His crew was done in three days (Day 1 - demo, Day 2 - concrete pour, Day 3 - clean up and sealer). I am very happy with his work and the area gave my BBQ grilling area more character. Definitely will be spending my most of my summer back here."

Concrete Leveling questions, answered by experts

Many contractors offer warranties for their work. Confirm terms before starting the project.

Charges correlate with surface size, settlement depth, and access, often yielding significant savings over concrete replacement.

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.

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.

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.
