Reasons Why Mud Jacking Can Fail,Read on...
BEWARE OF PYRAMID SCHEME !!!!!!!!!!!!!!!!!!!!!!
Before you hire a mud jacking company Here are some very important facts you need to be aware of. One negative issue sometime associated with mud jacking is a term called “pyramiding” or “coning”
This “pyramiding or coning” occurs when the mud jacking slurry is too stiff. By allowing the slurry to be too stiff, it will build a pyramid or cone directly under the injection hole, which prevents the slurry from completely filling the voids under the remaining concrete. If the concrete is raised using this technique, unbeknown to you, the voids are not completely filled the concrete will soon settle again.
KB Mudjacking’s of Perry Kansas method of a professionally mud jacked slab evenly raised by first filling the void, then continuing to pump, floating the slab back up into place.
This “pyramiding or coning” is a practice some mud jacking companies will use to quickly raise concrete back up, but fail to fill the voids for numerous reasons such as:
• The mud jacking company may have employees working for them that are not properly trained.
• The mud jacking company has placed an unrealistic work load onto their crew scheduling more jobs than they can handle, the crew struggles to keep up and cuts corners by pyramiding or coning to quickly raise the concrete without filling the voids, so they can move to the next job.
• Some Mud jacking companies are under equipped and do not…or can not...carry enough mud jacking material on their truck, therefore “pyramiding or coning” is a common practice among such mud jacking companies to quickly raise the concrete, but they are unable to fill the voids due to the lack of material. Beware of these companies that do not have the load capacity or who are working out of the back of a pick-up truck or trailer. We carry 10 yards of material on our truck, weighing 28,000 lbs!!!
• Most all Mud jacking companies do not own fully automated equipment and are limited to shoveling the material by hand out of the back of a truck (no one likes to shovel!) so, to reduce the amount of back breaking shoveling, its much easier for them to cut corners by “pyramiding or coning” to raise the concrete but fail to fill the voids.
Yes, If you have poor soil mud jacking can fail, but if you tear out and replace concrete on top of that same bad soil, that to can fail. My experience is, in most cases soil will self compact itself in ten years with the weight of the concrete on top of it. So if you have a slab of concrete that has been there for ten years that has settled and you
correctly mud jack it back up filling all the voids and use a non organic material such as pulverized stone like we used mixed with portland cement, that slab can last a lift time. My family has been in this business for 40 years, we have jobs that we mud jacked 25 years ago and has not settled to this day. So say want you want about mud jacking but please know all the facts first
We save people thousands of dollars everyday and have many very happy customers. Out of the 200 plus mud jacking jobs I did last year I had one recall, it was a driveway that was down 3" we jacked it back up, over the winter it settled back down 3/8", we stand behind our repairs, without any questions I went back out re-drilled the same injection holes and made the adjustment. The client was very happy, he told me he had estimates before contacting us to replace the driveway, lowest bid was $6000.00, we mud jacked it for $900.00, so you decide, not everyone has $6000.00 laying around they want to spend on a driveway!
