"Repair team was very professional and it was clear they knew what they were doing. I asked the team leader how he knew when to stop injecting the poly substance under the walkway and his answer was a simple "experience" and "patience" He proved that when all the sunken concrete rose to exactly the right height! You cannot go wrong with this company. Costs are a little high, I think, and it would cost somewhat less to replace the concrete, but it probably wouldn't match the existing slabs."
"He came and looked everything over told us so many things that were so helpful, and said at this time we did not need to do any repairs. I cannot thank them enough and charged us nothing. Thank you. If I do need something in future you can I know they will be my first call. I love honesty."
"Mr. Wise and crew showed up and worked hard to get the job done. Everyone had such good manners when addressing me and everyone was very kind. I would recommend this company to anyone who needs any type of foundation repairs done!"
We have been in business for 175 years, and our foundation work is backed by a Lifetime Warranty and Guarantee. It's important to begin any enterprise with a firm foundation and no one knows better than Abry Brothers. Abry, a skilled shorer, arrived in New Orleans from Frank- furt, Germany. Realizing he had a niche in the construction market due to the unstable delta soil which is characteristic of the area, Abry purchased a lot at 816-18 North Johnson St. and set up shop. He ran the business alone until the 1860's when he was joined by his son Emile. Emile's three sons came into the business near the turn of the century and operated under the name "Emile Abry &Sons." His sons would later change the name to Abry Brothers. Six generations later, Abry Brothers continues to be a stabilizing force in the building industry, handling all sizes and types of jobs. Also serving Louisiana areas such as Alexandria, Shreveport and Lawton, also Lawton, Oklahoma.
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.
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.
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.
It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.
There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.
