"Groundworks did an excellent job for us. Everyone was so professional and we know we received quality work for a reasonable price. It has been over a year since our waterproofing project in the fall of 2023. At that time we had “nuisance leaks” in our basement but they were becoming more and more problematic. We hired Groundworks to waterproof our basement. The winter spring and especially the summer of 2024 were very wet where we live. We were so proud of our lovely dry basement. It is now the summer of 2025 with lots of rain but there have been no leaks since Groundworks completed our basement project. We are very happy with their work!"

"I knew it was going to be challenging to find an investor that would lend me money for this real estate venture.  I have lived 20 years in a four unit historic condominium building in downtown Jersey City and I wanted to buy the unit above me as an investment property.  But with Fanny Mae and Freddy Mac rules, they would not give me a loan because I would own half the building and this would give me too much control over condo association decisions.  I checked with Angie's List where Central Lending was well recommended and spoke with Mark, the president of Central Lending, about my situation and that I needed an unconventional loan outside of Fanny Mae and Freddy Mac oversights.  After many disappointments and on the very last day of my contract with the seller, Mark found a lender.  And on the very last day of the window to the loan, it closed.  I cannot thank Mark and his assistant Judy enough for their patience and steadfast of seeing this through.  I cannot tell you the emotional roller-coaster ride I went through during the 4 1/2 month duration.  There were many moments that I wanted to give up but Mark reassured me that the sale would happen.  Without Mark's personal intervention with the lender and title company, this deal would not have closed.   You can be sure that when I am in the market to buy unit #3, I will not hesitate to contact Central Lending.  Thank you so much."

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.

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.

Common issues with concrete that may require professional repair or resurfacing include cracks, spalling, uneven surfaces, and weather damage.

Polyjacking can be a permanent solution to sunken concrete if you also address the underlying issue—like poor drainage—at the same time. The polyurethane material itself can last as long as or even outlast the concrete you’re lifting it with. Your sunken concrete issue will likely return if you don’t couple polyjacking with proper drainage to prevent future soil movement and sinking.

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.
