"Larry came out and did an analysis of our exterior drainage system, as we were having some puddling issues in the front and rear of our yard. We had just moved into the home a few months prior and Larry also did an analysis of our basement as we were having some concerns about the slightly bowed wall in our basement. Larry was very thorough and took a lot of time to go through the details of the exterior french drainage system he would install. He responded back to us in a timely manner and was extremely reasonable with their quote compared to other bids we had received from other contractors.
Larry and his team came out to the house and made quick work of a tedious job.  They took good care to keep the job-site as tidy as possible. Although Larry changed from the original plan, we felt comfortable with this as he was very thorough when explaining the reasons behind the change and we felt he had our best interest at heart. If we had any questions Larry was always available to answer them for us even when we called at 9pm.
We had a walkway that they had to cut through in order to run the piping for the drainage and Larry even added concrete to fix the walkway even though it wasn't in our original proposal.
We feel like with the work that was completed we got an excellent price and we have the peace of mind knowing that the job was done properly.

"Ed was very nice to deal with.  He knew his stuff and seemed to be very knowledgeable in dealing with kool deck.  We had damaged kool deck that was installed by another mason 8 years ago who did a really bad job.  Ed's crew painted over the kool deck, cleaned and sealed my stamped concrete.  Everything came out nice and the way he said it would.  Stamped concrete
formed a white substance after a few days of application and Ed didn't hesitate to come back to fix it and made sure it was done to
perfection.

Concrete Mudjacking questions, answered by experts

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. 

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.

Generally speaking, push piers—or steel piers—are the best option for underpinning, as they reach down to solid bedrock to find support for your foundation rather than relying on soil, which could be subject to the same issues as the soil directly below your foundation. However, the best underpinning method for your home depends on your location, how far down the bedrock is, and the type of soil in your area. Helical piers are usually the best option for sandy soil or in areas where the bedrock is too deep to use steel piers.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

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.
