"The Zavza Seal team were polite, professional, proficient. They removed tile from our Church basement fellowship hall and replaced with an overlay of colored painted and speckles over our existing concrete. The work was done with care and concern to produce the best possible outcome. They worked diligently to get the work completed to our satisfaction. Excellent workmanship."

"LI Waterproofing had done extensive work in my basement for the previous owner, so I opted to give them a try myself to resolve new problems that had not been previously addressed. John and his men were responsive and professional.  The work was done as expected and in a reasonable amount of time.  The price was right for the scope of the work requested.  Hand digging was required to expose the foundation outside.  I opted to remove the plants in my garden bed myself before the work was done.  I'm glad I did so. The men worked around the one larger hydrangea I did not move, and it was pretty roughed up during the process.  (I cut back the broken branches that were covered with tar, and I think it will be OK.)  We have had one good rain since the work was done, and the repaired areas in the basement show no signs of dampness.  So I am hopeful.  My sole criticism of the work is that clean-up could have been done better.  Gravel used to fill the window well was spilled into the adjacent garden bed on top of plants.  I spent about 2 hours sorting that out and sweeping the porch and basement where dirt and cement were left.

"Jose is an AMAZING Artist. He built everything by hand, never used machinery, worked from early morning to night and got the work done very professionally and beautiful. All the masonry work was done very precisely and perfectly, he never cut any sprinkler lines because he dug all the soil by hand using only a shovel. I am amazed by his work and I am honored to get the chance to work with him. I would definitely recommend him to anybody who needs masonry work and definitely use him again."

"Very well. Malik and his team were efficient and competent. Above all, he was communicative and responsive throughout the process. He planned the world closely with me and made sure that I was aware of all plans and updates. My only concern was that he didn't take credit cards, which made tha arrangement awkward and costly for payment."

Concrete Leveling questions, answered by experts

A good slump height really depends on the project, but there is a use for nearly all slump levels. For example, low slumps are best in projects that require structure, such as curbs and roads. High slumps often require additional reinforcement, but they flow more freely into hard-to-reach spaces.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation. 

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.
