![]() ![]() Professionals may recommend mudjacking because it’s cheaper and simpler. Why You Should Choose a Polyurethane Injection It’s also a versatile option that can repair concrete anywhere throughout your home. It’ll give you a better value for your money and a longer-lasting, better-looking repair. This means you won’t have to repair the concrete again as often, saving you money over time.įor these reasons and more, you should consider a polyurethane injection over mudjacking. A lower initial cost doesn’t always mean a better value.Ī polyurethane injection lasts longer than a mudjacking repair job. Mudjacking is the more traditional and less expensive method of concrete repair. Why Polyurethane Injections Are a Better Value It’s stronger, doesn’t retain moisture or pollute the environment, and can reach areas that are inaccessible to mudjacking equipment.ĭespite these benefits, you may be left wondering how long does foam jacking last? While mudjacking usually lasts 2-5 years, polyurethane can last much longer if properly maintained.Ĭheck here for more information on polyurethane vs. It’s less invasive because it requires smaller and fewer drilling holes. Water can also get in, leading to shifting slabs and further damage and settling.įoam injections cure in 15 minutes compared to a full day for mudjacking. There are more holes that are large enough for weeds to grow through them. It can be cheaper and easier to control.Īt the same time, mudjacking uses heavier materials, and requires more cleanup. Mudjacking has some advantages over polyurethane concrete raising. Weighing the pros and cons of each concrete repair method is the best way to decide which is best for you. This makes the repair a long lasting solution.įor more information, check out all the steps of the polyurethane process. The benefit of using polyurethane over “mud” or sand/cement is that it will not breakdown overtime. It’s also perfect for concrete that needs to return the service quickly like roadways thanks to its quick drying time. Polyurethane concrete raising works best for large, heavy, or sensitive concrete slabs. It raises the concrete while stabilizing it and filling any gaps between the concrete and the soil. The foam can expands up to 7 feet at each inject hole. The high-density polyurethane foam is the spray through the holes and will begin to fill all the voids below the concrete. The first step in a polyurethane injection repair project is to drill penny sized holes. The material and equipment is similar to what is used in spray foam insulation however the foam used for lifting concrete is a lot stronger. PolyLift or Polyjacking uses high-density geo-technical expanding foam to raise and stabilize concrete slabs. You can learn more about this check out more problems with mudjacking. So this process in a area that is going to be exposed to a lot of water is not ideal. Lastly, the sand and mortar used in mud jacking is not water proof materiel and can easily erode away over time if water is draining along the sides and underneath the slab. It can also cause more problems for severely damaged concrete because it can’t fill every hole and may lead to sinking over time.Īlso, if the soil below the concrete is not able to support additional weight – mudjacking materiel weighs around 100 lbs per cubic foot, then the concrete slab may sink again over time. It won’t work for slabs that are heavy or load-bearing because it doesn’t have enough power to move them without causing damage. There are some projects where mudjacking isn’t the best choice. It works for slabs, driveways, porches, walkways, decks, steps, and more. Mudjacking is best for concrete that’s in good condition but is no longer level. This mixture is then pumped into holes drilled into the concrete to raise and level it. Sand, cement, and other materials combine to make a mixture known as a slurry. Mudjacking is also known as concrete leveling, pressure grouting, and slab grouting. Read our guide to understand the differences between mudjacking and polyurethane concrete raising and how to choose the best method for your project. They have a similar purpose of repairing and leveling old or damaged concrete.ĭespite their similarities, it’s important to know what sets these two methods apart to choose the best method for your project. Mudjacking and polyurethane injections are two of the most common concrete repair methods in use today. Aged concrete is prone to all sorts of damage, making it both an eyesore and a safety issue. While it’s long-lasting, it doesn’t stay in good condition forever. Concrete is the second-most used substance on Earth, only surpassed by water. ![]()
