"After interviewing several companies to have our kitchen remodelled, we selected VKB, and we are happy we did. VKB provided a lower estimate than other companies, and their reviews were good. As our designer, Sean was easy-going, accommodating and patient in explaining our options. He promptly created the 3d pdf files with the design of our kitchen, which were helpful to have throughout the project. Adam was in charge of our project, and his responsiveness and understanding were outstanding. At one point we were a bit unhappy with a corner cabinet, but reluctantly we felt we needed to "settle" because there was not sufficient space for a Super Susan. Adam made some research and promptly contacted us with a solution that was perfect for enhanced functionality. Last but not least, Ismar, our foreman on the job was professional, responsive, pleasant, and amazingly skilled. He and his team worked diligently on the electrical portion, cabinet installation, backsplash, appliance installation, and painting. Everyone accommodated us to the best of their ability and always left our house clean and orderly. Well done, VKB!"
"Workers wore masks and kept a good distance when interacting with us. I am thrilled with the concrete leveling. If the driveway sinks again within 3 years they will fix it for free. Nice folks and excellent results."
"I helped my daughter with this crawlspace encapsulation work on her house. I solicited 3 quotes and it was an easy choice to go with Basement Waterproofing Nationwide. From the initial inspection and quote with Tim, the financing and finally the work with Will and his crew, everything went well. They completed the job to my expectations, answered all my questions and kept me informed all along the way. They actually finished the job in 3 days instead of 4. I highly recommend giving them a chance."
"Romualdo fixed our basement concrete floor to make it even and prepare it for vinyl flooring installation. His services were reasonably priced and he took the time to advise us on the different alternatives that we had to get the job done. He was kind and did an excellent job."
"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."
"Great guy, casual approach, does not ask enough questions. As a homeowner, I don't have his knowledge and is up to him to educate a little better. Overall, very, very good."
"i would highly recommendations. This company from looking from a distance looking great. I am watching the work at my neighbor gargage been build by this company.I would recommend this company for future project. Thank you"
"Were willing to work with budget, scheduling & any concerns I had. Once we agreed on cost, they had a crew out within 2-3 weeks. I had a full perimeter solution completed on a small house within 2-3 days."
"Make sure the person giving the estimate explains exactly what it looks like. They did not bring their own water to mix the cement. We had to remove the water tank so that they could work and ended up hauling water from the neighbors house."
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 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.
Mudjacking is your best bet for leveling concrete on a tighter budget. It’s less expensive than foam or grout mixture. For smaller, surface-level issues, you could also use a self-leveling compound, which creates an even surface over existing concrete—it’s a budget-friendly option suitable for DIY enthusiasts.
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.
Concrete leveling is absolutely worth it if you have sunken concrete slabs and want to restore them to level, especially if the slab is part of your home foundation. Concrete leveling is less than half the price of replacing concrete sidewalks, patios, walkways, and pool decks, and it’s about a quarter of the cost of replacing a foundation. If you also treat the underlying problem, it can be a worthwhile and permanent solution.
