Mudjacking / Slabjacking

WHAT IS MUDJACKING or SLABJACKING?

Mudjacking means the process of lifting a building, driveway, or any object by pumping concrete (known as mud to people who work with it) underneath the item to be lifted.  Different types of concrete can be used.  Usually, a low strength concrete is used. It is also performed by injecting polyurethane resins.  When the resins mix underneath a foundation, they form a plastic that contains gas bubbles.  As the gasses and plastic expand, they can lift buildings.  Polyurethane injection is much more costly than lifting with concrete, but it is much more precise and controllable.

 

ADVANTAGES AND DISADVANTAGES?

Mudjacking is relatively inexpensive and it is fast. The disadvantages are:

  1. that it comes with no warranty,
  2. it can lead to your sewer lines being filled with concrete,
  3. sometimes the concrete emerges in unexpected places, such as the inside of a wall, where there are unidentified holes in a slab.

WHEN SHOULD IT BE USED?

At Advanced we use mudjacking as a convenient and inexpensive way to lift pool decks, patios, driveways and other items made of concrete that is 3 to 6 inches thick.  It is cheaper than pouring new concrete, and can often be completed in a day or two. It is used when a foundation is so weak that piers or pilings can not be installed. It should not be used under a foundation if there is a chance that the soils under the mud will expand. If soils under injected mud or concrete expand, the soils will push up on the overlying structure and move it upwards.

IS THERE A WARRANTY?

Because mudjacking relies on the underlying soils to support whatever has been lifted, there is no guaranty.  Mudjacking is used most commonly to avoid the cost of repouring flatwork (driveways, patios, sidewalks, etc.).

Workers were very professional and hard working. They dug up around the house and put plants back to look nice. This company also has a trust to forever be able to redo warranted work.read more

I can't too highly recommend this company. I had work done of my foundation by another company several years ago. That work did not resolve the problem, and that company did not fix. Advanced was recommended to me by mother, who said they were the best in the business. I agree! They were polite, professional, charged reasonable prices, and did excellent work. They also have a strong guarantee that is backed by a trust. I can't imagine why you'd use any other company.read more

Advanced Foundation repair is the only way to go! The engineer, Eric was kind, helpful and informative! The crew under Haynard's watch was unbelievably considerate. The crew was in and out of our house for 5 days. Everyone of them were happy even in the 90 degree weather. They work hard and were very polite. If you saw my house now you would never even know they were here. They cleaned up every night and on the last day it looked like new! Very thankful to have been able to work with them.read more

Advanced recently performed our foundation repair and did a fantastic job! The job took four days and throughout the process, the workers were on time each day, were kind and courteous. They left our house clean each day and took great care in making my wife and newborn comfortable during the repair. They came back out to make adjustments, as was expected, and I am more than pleased with the results. Thanks to Juan Martinez, Miguel Mata and Ernesto Alvarato for doing everything I requested. I highly recommend Advanced Foundation Repair, they know what they are doing.read more
