If the concrete stairs on your front porch are sinking, becoming uneven, or pulling away from the porch, you may imagine the repairs will be expensive and complex. However, mudjacking could be an easy solution. This is a method for raising just about any type of concrete whether it is stairs or a slab. Here is an overview of how mudjacking works.
Why Concrete Sinks
There are a few reasons why your stairs are sinking. If there is a big tree nearby, massive roots could be pushing up on one side. A more likely cause is shifting of the soil under the sunken side. This happens if the soil washes away because it wasn't compacted properly. It can also happen if a mole or some other burrowing mammal creates tunnels under the concrete that eventually collapse on themselves. The purpose of mudjacking is to pump a muddy slurry under the sunken side so it raises to be even with the higher side. This also works if you need to elevate the steps on one side to compensate for lifting caused by roots.
How Mudjacking Works
The slurry that's used to raise concrete looks like mud, but it is a concrete mixture that hardens when it dries. To get it under the concrete, the contractor drills holes in strategic places in the stairs. Then, the slurry is pumped through the holes. It flows under the stairs and fills the void in the soil. When the void is full, the pressure of the slurry slowly raises the concrete. The contractor stops the flow when the stairs are level and stable. The slurry then hardens just like concrete does, so the repair is permanent. Mudjacking is a fairly quick procedure, especially on an area as small as stairs. You'll be able to use your steps right away since the concrete on the surface stays dry and hard.
Why Mudjacking Is A Good Option
Mudjacking is much easier than tearing out your old steps and putting in new ones. Plus, the repair work will be done much quicker so your stairs are not out of service for very long. The machinery used is fairly quiet and the process doesn't tear up your yard. Mudjacking is a good way to repair your steps quickly so they don't pose a tripping hazard for your family or guests. The first step is to call a contractor for an evaluation. Not all sunken concrete is a good match for mudjacking. If your steps are crumbling and unsafe, then it might be best to replace them. Mudjacking doesn't repair surface concrete; it only fills in the space underneath.
