"Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason. Waterproofing the basement and super sound and solid work! Doug was professional and very good at keeping me in the loop with the project over the 3 day visit, and created a solid system that we are confident will keep water out of the basement forever. Above and beyond as well with problem solving when having to find solutions to fit our basement layout, all with a solid financing option/great price and 5 year warranty/ yearly inspection plan. If you are stuck with water in your basement, get Groundworks working for you ASAP!"

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"When I first met Stavros, he discovered damage that another company completely missed. His inspection was thorough and he explained the situation so we could easily understand what was happening and what we needed to do to repair it. He and his crew then did a very thorough job repairing our concrete foundation that had cracked and was sinking due to problems with the subsoil, as well as leveling the concrete slab in our basement. He took care not to damage our property, and even maneuvered his equipment under our deck so we didn't have to remove it to complete the repair. He and Athena genuinely care about their customers, and were empathetic and kind throughout what was a difficult experience for us as homeowners. I would not hesitate to recommend Arta to anyone who needs foundation work."

"I called at 8pm on Friday he was here 7:30am Saturday morning. We moved in and found out our well was no good and that we needed a new septic system. Plus some work inside that we knew about. We called a few places just to get prices because a lot of companies try to take advantage of people our age and when I tell you he showed up gave a price a lot less than what the other companies gave and told us what needed to be done not what he wanted to do unlike the other places. I would highly recommend him and his crew I already have a few of my neighbors loved the guys and came and asked for there number good luck Christopher with your company and thank you from the bottom of my heart"

"Mike did a great job fixing my chimney and replacing some of the bricks. He also waterproofed the whole thing. While he was up there he noticed a crack in the inside liner. He fixed that also. He showed me all the work before and after using a drone. Did a great job and didn’t have to wait long to get it done. He also fixed all the caps on my stone wall that had come loose. Everything looks great. May have a leak in the roof and if so will certainly hire him again."

FAQs for concrete injection leveling mudjacking projects in Portsmouth, NH

Mudjacking and foam jacking differ significantly in both materials and methods. Mudjacking uses a cement-based slurry to fill voids beneath a slab, while foam jacking uses expanding polyurethane foam delivered under high pressure to achieve superior structural support. This material distinction enhances load-bearing strength and overall stability in your repair.

Mudjacking takes between one and three days to dry completely. During this time, it's important to avoid putting weight on the slab until it's fully cured. The drying time depends on the project size and environmental conditions. In contrast, polyurethane foam used in foam jacking can cure in as little as one hour.

No, mudjacking is not a permanent fix for sinking concrete. While it effectively lifts the slab and can last five to 10 years, it doesn't address underlying soil issues that may cause future sinking. For a more permanent solution, you might consider foam jacking or complete slab replacement, which can address deeper structural problems.
