Mudjacking Vs. Polyurethane - What is the difference?

The #1and most frequently asked question posed to HMI personnel, at seminars, on the phone or on line is “what is the real difference between the polyurethane and mudjacking concrete lifting processes and which is better?”
This is a complex question with NO real answer since better is relative to perspective and the priority of criteria. In this video we will attempt to review each of the criteria with which these two approaches are most frequently judged. With this approach it will be left to you to decide which criteria is most important.

I have a 63 year old garage and the ground has settled roughly 3-4 inches below a 10x22 slab garage floor. I was told to use LSM, which is different from mudjacking. What do you think is better to fill voids that will ensure that it will be strong enough to support the weight of a car? Mudjacking, Poly or LSM?

Either Mud or Poly would work well for this project. However, the longevity of Polyurethane will stand up against the lengths of time for another 63 Plus Years

What if a footer is needed around back of deck.Hallow from pool to back.5+feet

Whats the warranty on both?

our installer of poly really messed up our driveway. We now have many cracks, and uneven slabs. This is now beyond repair and we are stuck with an extremely poor quality job, and permanent damage to our driveway. The driveway was previously mudhacked and it lasted for 10 year before it started settling. Wish we would have mudjacked instead of poly.

There are many experienced polyurethane installers. It sounds like you had an unexperienced installer. HMI has our installers take an exam.

Thanks, this really helps.

My driveway turned out great with the foam. Couldn't the mud erode away with water? I would watch rain drain into expansion joints, it had to move sand away and make a void. The joints are sealed now.

[@HydraulicMudpumpsInc]

To answer your question, Yes mud could erode over time. Mudjacking is a generic term for the process using a grout. Different materials are used. Sometimes Portland is use which helps stiffen the grout and makes it harder to erode. But if water is the issue causing settlement, then Polyurethane is going to be the best long term solution.

Can you give some examples of how much various polyurethane lifting jobs cost the contractor in materials and time , and how much customers are charged. How are jobs estimated. Thanks

[@HydraulicMudpumpsInc]

Most standard residential jobs are anywhere from $500 to 1000 dollars. Polyurethane is estimated and completed per the pound. Nationally we see an average of $10-$14 dollars per pound. Most all contractors build their overhead expenses into the Per pound gap. The idea behind Polyurethane lifting is to be ½ to 2/3 the cost of replacing the slab that can be lifted. As per estimating, we look at square footage and how much lift needs to occur. There is a formula used as well as estimating software that makes it fast and efficient to estimate projects.

I live in an area that has experienced a great deal of water contamination from foam products. I the polyurethane that is used for this application environmentally safe for the ground water. I do not have city water.

[@HydraulicMudpumpsInc]

HMI is committed to manufacturing environmentally friendly products, from our use of recycled and biobased raw materials to the environmental effect of our final product. Our cured polyurethane foam is chemically inert. Leaching tests have been done on many of our products to ensure that no dangerous chemicals are leached from our foams when exposed to water.

And HMI sells the poly and not the mud so they lean to poly
