For these reasons and more, you should consider a polyurethane injection over mudjacking. It'll give you a better value for your money and a longer-lasting, better-looking repair. It's also a versatile option that can repair concrete anywhere throughout your home.
Mudjacking can last for long periods, but it is inherently less reliable and usually does need to be replaced. The injected materials are extremely heavy (30-50 times heavier than their polyurethane equivalent) and can cause a new round of soil compression (and foundation sinking) beneath the slab.
Polyurethane foam injection—also known as polylifting, polyjacking, or PolyRenewal™ (our method)—is the quickest and easiest way for professionals to lift sunken concrete. Lightweight polyurethane foam is injected underneath the affected slabs through penny-sized holes.
So How Long does Concrete Lifting with Polyurethane Foam Jacking Last? In the right conditions, Polyurethane Foam Jacking can last lifetimes. When approaching your project it's important to address the issues that could cause the life of the polyurethane foam jacking process to diminish.
Concrete Leveling Price per Square Foot
Mudjacking can cost between $3 and $8 per square foot according to Angi, while polyjacking can cost between $5 and $25 per square foot, according to sources across the web.
The average cost for mudjacking is $4 per square foot, but you could pay anywhere from $3 to $25 depending on the type of material you use, the slab you're lifting, and how accessible your sunken concrete is.
Per Square Foot: On average, polyurethane concrete lifting costs between $5 and $25 per square foot.
QUIKRETE® Polyurethane Self-Leveling Sealant will achieve full cure in 7 to 14 days. Allow sealant to cure for 72 hours before painting or exposing to traffic. Allow 7 days for temporary water immersion. PRECAUTIONS Do not apply to frozen surfaces or through standing water.
For example, under normal wear and tear, a durability of more than 50 years can be expected for polyurethane insulation systems for buildings, more than 25 years for polyurethane used for insulation of refrigerators or more than 20 years for the application of polyurethane in vehicle bumpers.
Polyurethane Foam Leveling
The pressure from the expansion causes the concrete to lift, then the foam hardens, creating a new solid base for the concrete to rest on. Polyurethane foam concrete leveling uses smaller drill holes and can be less messy than both mudjacking and stone slurry grout leveling.
This method involves transferring levels between two distant points using multiple setups. It is widely used for precise elevation measurements in large-scale projects like roadways and dams. Differential levelling is one of the most reliable types of levelling in surveying, ensuring accuracy across long distances.
Concrete leveling costs range from $750 to $6,000+ depending on the size, accessibility, and material used to lift.
Epoxy offers higher levels of rigidity and adhesion than polyurethane, making it better suited for harder surfaces.
So, mudjacking is cheaper than pouring a new slab, but both solutions are not very cost-effective. Mudjacking will need to be repeated in another two to five years, while pouring a new slab won't solve the issue with the soil below it.
Urethane floors can be expected to last from 10 to 20 years, and even longer with proper cleaning procedures, maintenance, and touch-ups. With thermal shock resistance and better resistance to organics, they will have a longer life than an epoxy floor in a food and beverage environment.
Concrete Leveling Repairs Can Last a Lifetime
Concrete leveling repairs, when done correctly, can last for a looooong time. Whether you choose stone slurry grout leveling, polyjacking, or mudjacking, your concrete can stay level for 20, 30, or even 50 years – or the life of your slabs – with proper maintenance.
As a general rule, polyurethane can take as long as 30 days to completely and correctly cure. It would be best to give yourself a full 3- days before using your wood floors following a polyurethane treatment for the best possible outcomes.
The epoxy and polyurethane self-levelling floors from HIM last for years and adhere well to the substrate. Both self-levelling floors can be made in most RAL colours and also in a concrete look or scattered with flakes.
While mudjacking materials offer higher compressive strengths, polyurethane foam allows you to work in areas where concrete surfaces and slabs may show significant damage and the maximum weight of treatment materials is a factor in how you can mitigate the issue.
Depending on the grade used, polyurethane lifting foam can support hundreds of thousands of pounds of weight. Some higher commercial grade foam is even rated to support millions of pounds.
If your slab is intact, concrete leveling is often better than a full slab replacement. For a replacement, you'll end up paying to remove the old slab and dispose of materials, deliver new concrete, and then have a new slab poured.
In addition to the problem of excessive weight, a wet slurry will typically shrink as the water evaporates from the material. The shrinkage alone can allow raised concrete to drop. This accounts for why mudjacking companies are notorious for “over-lifting” slabs.
Concrete leveling is made easy with the PolyLevel system. It permanently lifts and stabilizes sinking concrete slabs with high-density polyurethane foam.
However, if this is something that needs to be done ASAP, it can be scheduled in 1-2 days. Average mud jacking jobs usually take a couple of hours. Larger jobs take longer, but usually not more than 1 day.
