What is Mudjacking?
Mud-jacking, also known as slab-jacking, or simply concrete raising, is a process where a slurry mixture is pumped hydraulically under a slab filling any hollow areas under it and causing it to raise back to it’s original level.
How Does Mudjacking/Slabjacking Work?
We drill 1 1/4″ holes through the slab that has sunk, approximately 2 -3′ apart. We then pump a crushed-limestone slurry mixture under the slab. As the limestone is pumped under the slab, it forces the concrete to raise slowly. When we reach the desired level, we stop pumping and clean the holes out and patch them. The crushed limestone then dries hard underneath the slab and holds the slab in place.
What are the Advantages of Mudjacking Over Concrete Replacement?
In most applications, the concrete can be used the same day. If it is a driveway or garage floor being raised, it can typically be driven on after only one or two days. Another advantage is the cost. It is normally half or less of the cost of replacement. Also, there is no worry as to whether someone will deface the new concrete in some way before it has set up. When replacing concrete, some people only replace the sections that have sunk, to keep the cost down. this causes the concrete to be different colors and not match. Mud-jacking keeps all of your original concrete the original color.
How do you Straighten Basement Walls?
In order to straighten a basement wall, the pressure from the outside must be eliminated. Therefore, we must excavate on the outside of the wall, removing the dirt so the wall can be straightened. Once the pressure has been removed, we install 4″ steel I-beams into the floor next to the wall, where needed. We then use our engineered system to push the wall straight. Once the wall has been straightened, the beams are permanently bolted into t he floor joists, providing a permanent solution to your bowed wall.
Do all Bowing Walls Need to be Straightened?
No, they do not. Many times a wall can simply be braced where it is at, if it is not bowed very badly. Using this method eliminates the need to excavate on the outside, and lowers the cost of the repair significantly. When bracing the wall, the I-beams are used in the same manner as when straightening the wall. The braced wall will not be straighter than it was, but it cannot ever get any worse.
What is the Cost of Straightening or Bracing my Walls?
Just as there is no way to tell you how much it costs to fix your car over the phone, neither is there any way to answer that question before looking at the condition of the walls. This is why we encourage everyone to contact us for a free estimate.
