The process of concrete lifting is often a very complicated one. Traditionally, people would utilize “slabjacking” or “mudjacking” to manage their concrete lifting needs. This required pumping a concrete slurry through the concrete slab to keep the slab from sinking any further. As you may expect, this isn’t a very effective method of managing concrete issues. 

Instead, you might want to consider concrete lifting with PolyRenewal™. PolyRenewal™, which is a form of polyurethane foam injections, is a great method of lifting concrete. If you have concrete that you need to lift, PolyRenewal™ could be your best choice. Here’s everything you need to know about PolyRenewal™. 

Uses for PolyRenewal™ Concrete Lifting 

What can you use PolyRenewal™ concrete lifting for? There are a great many potential uses for PolyRenewal™, including all these options. 

  • Slab Foundations 

A slab foundation can be an incredibly detrimental area in which to see concrete sinking. If you’re starting to see concrete sinking in your slab foundation, you need to make sure the slab foundation has the support it needs to continue to hold up your home. Polyurethane foam injections can help you bolster your slab foundation back to its initial position. 

  • Patios and Porches 

Most homeowners’ patios and porches at least have concrete as a foundation; it’s uncommon for there to be no concrete whatsoever in the process. Even if you have a wooden patio or porch, concrete may lurk underneath. When you utilize polyurethane foam injections, you’ll be able to make your patios and porches level with the rest of the home again. 

  • Driveways 

A driveway tends to carry a lot of weight; you may park a car on top for many days at a time, sometimes with other items that add even more weight. That weight can then lead to driveways sinking quickly. You need a way to lift your driveway back to the right level and make sure it maintains that level, and polyurethane foam injections is the right way to do it. 

  • Sidewalks 

There are many sidewalks across your home. You likely have sidewalks leading out to your driveway and outside your home and you may even have additional sidewalks in your backyard. These sidewalks can sink and crack just like any other concrete, especially after repeated walking. Raising the areas with polyurethane foam injections is a great way to make it more stable. 

  • Concrete Pool Decks 

Concrete pool decks can sink just like any other concrete area. However, many homeowners don’t think about concrete pool decks as being concrete, which means they might have some confusion if these deck areas sink. With polyurethane foam injections, you don’t have to worry about water damage setting in and negating your hard work in lifting the concrete. 

How Does PolyRenewal™ Work? 

When you use PolyRenewal™ for concrete lifting, an expert will come and help you install it with just a few steps. These are the basic PolyRenewal™ steps. 

  • Step One: Drilling Holes 

First off, the PolyRenewal™ process requires that you drill holes to inject the PolyRenewal™ product. If you were doing the traditional method of slabjacking or mudjacking, these holes may need to be as big as a soda can, which can be frustrating and annoying to fill. However, when you use PolyRenewal™, these holes are only the size of a penny. 

The expert who’s helping you with the PolyRenewal™ process will strategically drill these holes into your concrete slab, making sure to space them out properly and drill them into the right areas. Ideally, they should be out of the way but still close to the center of the area that’s started to sink. This way, the polyurethane foam injections will have enough space to expand. 

  • Step Two: Foam Injection Ports 

Next, the expert will put foam injection ports into the holes they drilled in the first step. These foam injection ports make it even easier for the expert to know exactly where the foam is going to go. They can also make it easier for the expert to know how much foam they’re using and how the foam will expand to fill the space. 

From here, the expert may take a step back and look to make sure the entire area seems like it’s covered. If the expert has any concerns, they may take a second to readjust the foam injection ports just in case. After all, the process has to be quick because polyurethane foam injections start to set almost immediately after you inject it. 

  • Step Three: Polyurethane Foam Injections 

This is the step where the magic happens. The expert will inject the polyurethane foam underneath the slab, allowing it to expand and fill the voids underneath the slab of concrete. The slab will rise from the pressure of the polyurethane foam injections, which will allow it to come back to a level playing field with the rest of the concrete around it. 

The expert will have to make sure they’ve calculated the foam properly. You’ll need different amounts of foam for different holes and different cracks. When an expert is able to calculate the amount of foam correctly, they’ll be able to raise the concrete slab very precisely, especially if they’ve drilled more than one hole into the concrete slab. 

  • Step Four: Seal Holes and Control Joints 

Lastly, once the expert has completed the polyurethane foam injections, it’s important to finish the concrete properly. The expert will fill up the small holes they drilled to install the polyurethane foam, as well as any control joints they’ve decided on while creating a process to raise your concrete back to its initial level. 

The expert may use a variety of methods to seal the holes and make sure they appear almost unnoticeable. Once this process is done, you should be able to walk or drive on the concrete less than one hour after the polyurethane foam injections initially happened. 

Concrete Lifting


One of the most important things you need to think about when it comes to concrete lifting is efficacy. You might think of more traditional concrete lifting options as being the “most effective” options for lifting concrete, but PolyRenewal™ can actually be a great option. 

  • Very Lightweight 

The first benefit of PolyRenewal™ is that it’s incredibly lightweight. When you use a method of managing concrete lifting like slabjacking or mudjacking, you’re using concrete slurry, which is extremely heavy and can be very difficult to do. However, PolyRenewal™ is incredibly lightweight, which makes it much easier to lift the concrete in the first place. 

  • Extremely Unobtrusive 

It’s always a good idea to look at how obtrusive it might be to do any sort of home repair job. Unfortunately, concrete slurry is typically very, very obtrusive. You’ll often need to drill soda can-sized holes into the concrete, pour the concrete slurry in, and wait up to two weeks for it to set. PolyRenewal™ only takes around half an hour to set to 90% rigidity and requires penny-sized holes. 

  • Actually Raises Concrete 

The last and potentially most important element of PolyRenewal™ is the fact that it actually raises the concrete you’re having problems with. If you use a method like pouring concrete slurry, you’re just going to stop the concrete falling process. However, with PolyRenewal™, you’ll actually raise the concrete back to its initial position.

Some homeowners worry about whether they might need to replace their concrete slab entirely when they start seeing cracks. Using PolyRenewal™ is a significant benefit over replacing the concrete slab entirely because it’s a better option overall. 

  • Less Mess 

PolyRenewal™ is substantially less messy than replacing the concrete slab. When you pour concrete, you’re going to have to accept that there are many places where you’re going to have a lot of concrete overflow and spilling. Because PolyRenewal™ stays in separate containers until you mix it to go underneath the concrete, there’s no similar concern with it. 

  • Not as Expensive 

It’s also cheaper to use PolyRenewal™ than it is to pour a whole new concrete slab. Concrete slabs are hard work to pour and finish. That makes them also incredibly expensive. When you use PolyRenewal™, you don’t have to pay for all the work that it takes to pour a concrete slab, making it a much better opportunity. 

  • Much More Effective 

Overall, PolyRenewal™ is simply more effective than replacing a concrete slab. When you replace a concrete slab, you run the risk of unintentionally ignoring many of the problems that caused the concrete to start settling in the first place. If you instead use PolyRenewal™, you’re tackling most of those problems at the source.

When you’re trying to decide whether PolyRenewal™ could be a good option for your concrete slabs, there are a number of things that you need to think about. Depending on the extent of your concrete’s damage, PolyRenewal™ may be better for your slab repair. 

  • Minor Sagging 

If you’re just starting to note some sagging in your concrete, this is exactly when you should get an expert in to help you with concrete lifting. Minor concrete sagging can be an indication that there are problems underneath the concrete slab. When you use polyurethane foam injections at this point, you’re very likely to end up fixing the problem completely. 

  •  Significant Sagging Problems 

PolyRenewal™ may not be as effective when you have more serious sagging problems. However, if the main problem is that there’s a gap underneath the concrete, PolyRenewal™ can fill the gap underneath the concrete even if it’s fairly extensive. It’s important to think about how extensive the problems are and how much you’ll need to do if you’re going to fix the problem. 

  • Extensive Cracking Problems 

Once you start to have very serious problems with concrete cracking, PolyRenewal™ may no longer be able to fix things. If there’s just one big crack, you might be able to fix it with PolyRenewal™. However, if there are many little cracks spread across the surface of the concrete, you might need to repour the concrete entirely.

What do you need to maximize your PolyRenewal™ options? One of the things to think about is who’s installing your PolyRenewal™. There are two options when it comes to most home repair things: doing it yourself or handing it over to an expert. 

  • DIY Fixes 

Overall, a DIY fix is usually much more well-suited to something that doesn’t require a lot of expertise to do. For example, you can typically DIY a lightbulb replacement. The problem is that PolyRenewal™ application is much more complicated than a light bulb replacement. If you’re looking for a DIY fix opportunity, PolyRenewal™ isn’t it. 

  • Talk to an Expert 

Rather than trying to do this all on your own, you should instead consider talking to an expert. An expert will have the tools and knowledge necessary to help you install PolyRenewal™, which means you’re much more likely to end up with a PolyRenewal™ application that works the first time, rather than having to try and do it again.

The Advantages of PolyRenewal™ Over Traditional Methods 

Why might you want to consider PolyRenewal™ instead of traditional methods of concrete lifting like slabjacking or mudjacking? There are many benefits of PolyRenewal™ over these more commonly used methods. 

  • Less Invasive 

More traditional methods of concrete lifting are notoriously invasive. It’s common to have to drill holes around the size of a soda can, which the concrete experts then have to cover after the process is complete. This can end up looking ugly and extremely invasive, which may actually negate your reasons for doing it in the first place. 

The invasive nature is supremely lessened with the PolyRenewal™ method. With PolyRenewal™, you no longer have to worry about super-invasive slabjacking procedures. Instead, you just have to drill small holes about the size of a penny. Even if there are multiple holes throughout a single slab of concrete, they’re still going to be much less noticeable than slabjacking holes. 

  • Sets in About 15 Minutes 

With traditional concrete lifting procedures, you often need to wait days or even weeks for the concrete to set well enough for you to walk on it or drive on it. This can be completely untenable if you have a driveway or well-trafficked sidewalk that needs lifting. After all, you probably need to walk on it pretty soon. 

This is where the PolyRenewal™ method really shines. Concrete lifting methods may take a long time, but polyurethane foam injections set within about 15 minutes. That means the foam should be ready for pressure ranging from an individual walking on the sidewalk to a truck driving on top of it by the time the expert leaves your premises. 

  • Expands to Fill the Entire Area 

One of the biggest complaints homeowners have typically had with traditional concrete lifting techniques is the fact that it doesn’t actually raise your concrete for the most part. When the expert pumps in the thick slurry they use for concrete lifting, it will often create a “cone” shape, where the edges of the crack actually don’t touch the top of the concrete. That can lead to additional sinking in the future. 

Compare this to polyurethane foam injections, which expand once the expert pumps the material in. With these polyurethane foam injections, you can meticulously calculate exactly how much you want to raise your concrete and pump in just enough for it to raise the concrete back to its initial position. It’s a great way to maximize your concrete lifting process.

Manage Your Concrete Lifting Needs Across Your Home with PolyRenewal™ 

Concrete lifting can be extremely beneficial across your entire home, not just in certain locations of the home. Whether you’re looking for concrete lifting in your basement, out front in your driveway, or even around your pool, polyurethane foam injections are a great way to do it. PolyRenewal™ can make your concrete look exactly as it looked when you first poured the concrete. 

There are many areas you may need to manage for concrete lifting. Your entire home is extremely important in this situation; no matter where you have concrete, it’s a good idea to ensure it’s as level as possible. Make sure you schedule a free inspection and repair estimate so you can talk to a Complete Basement Systems expert when you have a concrete repair need.
