Q. What is mudjacking?
Mudjacking is a method of raising concrete that involves drilling holes
through the concrete surface and injecting a grout to fill any under slab
voids and raise the section to the desired grade. The procedure can be
used to raise virtually any rigid pavement. Lifts of one foot or more are
common; current technology makes it commonplace to raise a slab to a
tolerance of plus or minus 1/32 inch.
Q. Is mudjacking something new and does it really work?
Yes mudjacking works it is considered a valid means of restoring sunken
concrete to proper grades and is recommended by many engineers.
Mudjacking is not something new the process was developed and practiced
since the 1930'Although only in the last twenty or so years has it become
economically feasible to mudjack the smaller jobs. This has been made
possible through advances made in the equipment used. Also , mudjacking
becomes a more attractive option as the costs of concrete replacement raises.
Q. What are the costs of raising concrete or filling voids under slabs?
They vary from job to job, that is why it is necessary to make an
inspection of each job before giving a free estimate. However, it usually
costs half or less of replacing concrete.
Q. What kind of equipment do you use?
We use a diesel powered hydraulic mudjack made exclusively for the
purpose of raising concrete and / or filling washout voids. A truck mounted
hydraulic volumetric grout mixer that discharges directly into the pump
hopper is used for mixing. These units set in the street the grout is then
hosed to the work area, preventing any damage to the landscaping. We
also have an assortment of power and hand tools that are used in the
various phases of the mudjacking process.
Q. What pressure does the pump develop?
Our pumps are pressure compensated and have a volume control
so as to give us just the right pressure to do the job at hand. The P.S.I.
At the nozzle can range from a low of 50 psi to as much as 1500psi.
Q. I'm worried about it pushing in my adjoining basement wall. Could this happen?
This is unlikely to happen as the pressure normally takes the path
of least resistance, which in this case, is the raising of the concrete slab.
However we do have insurance in case something unfortunate and
unforeseen should happen.
Q. What do you use for material?
We process our own material by running it through our power /
processor located at our Dakota city facility. This screens out foreign
objects and blends the sands and silts together in a specific ratio. Then it
is loaded dry into our mixer truck and Portland cement and water are
added to it on the job site assuring a fresh mixture on every job.
Q. Will this fill material wash?
No not likely but if there is a drainage problem it has to be
corrected or it is possible that the soil under our injected material
could wash out and collapse our material.
Q. How many holes will have to be drilled and how big are they?
The exact layout and spacing of the 1 3/4 inch diameter injection
holes will depend on the thickness, condition and configuration of the
slab. However, they will normally be spaced 3 to 8 feet apart.
Q. Do you fill and patch the holes when you are done lifting?
Yes, we patch the holes and do a complete cleanup at the completion of the job.
Q. Do you have references?
Yes, since 1985 we have competed in excess of 5,000 jobs including residential, commercial,
industrial and municipal.
Q. How long have you been in the business?
We started our family owned and operated business back in
1982 and specialized in mudjacking in 1985, after having nearly 20
years background in the construction trades.
Q. Do you do the work yourself or send someone else out to do it?
I have been on every single job since 1985 and do all the nozzle
work myself. We take great pride in being a local family owned and
operated business.
Q. How long do most jobs take?
Most jobs can be completed in one day or less, some commercial
jobs a little longer. Thus eliminating the mess of being torn-up for
days or even weeks that occur when concrete is replaced.
Q. How soon can I walk or drive on the concrete after it has
been raised?
You can walk or drive on it immediately after raising it without
causing any problems but some time should be allowed to let the hole
patches dry.
Q. Does rain delay job progress?
Only while it is actually raining. Unlike replacing concrete, we
can resume work immediately after the rain stops, avoiding any
disruptive delays.
Q. Do I have to be home at any time while the work is being done?
No, there is no reason for anyone to be home.
Q. When is payment due?
You can either pay at the completion of the job, or we can mail
a statement that is due within 30 days.
Q. I have a commercial floor that has settled significantly. Would I have to shut
down operations to have it raised?
No, mudjacking in occupied buildings can be done while still operating or
if that is not possible it can be done at night or on a weekend so as to
provide little, if any interference with your normal business activities.
Q. Can mudjacking be used to raise and / or stabilize a structure that is sinking?
Yes - A little different procedure is used and some different equipment
is needed. For more information on this go to the Pressure Grouting page.
