Slab settlement is the movement of a concrete slab when the soil below the slab can no longer support the weight of the concrete. It happens when there are changes in the soil’s moisture content, a wash-out of soil, or poorly compacted fill soil. Slab settlement can happen anywhere: interior floor slabs, patios and decks, driveways, stoops and porches, sidewalks, and even in additions. So, when we say slab settlement in the concrete slab it does not have to be your slab on the driveway or sidewalk for it to be an issue that needs fixing.
Once the problem begins and you see a slab settling, the problem will only continue to get worse. There are three different ways you can fix this issue.
3 Ways to Fix Sinking Concrete
1. Replace it
One way is to have someone come out and completely replace the concrete slab. This would mean having the old slabs removed by jackhammering it into little pieces that then have to be taken and disposed of. If it is a slab inside the house, walls and floor coverings must be removed too. Once everything is removed and prepped, the concrete is poured and can take up to two weeks to settle before it can be used. This is a long process that is messy and will not solve your problem. It is not the slab that is the issue, it is what is below it so placing it won’t solve your problem (it will be a temporary fix).
2. Use Mudjacking
Another way to fix a sinking slab is through Mudjacking. This is an old method and involves drilling a series of holes in the slabs and a cement slurry or mud is pumped into the slabs through these holes to fill the void and lift the slab. This sounds like a good solution and it has been around for a while, but Mudjacking can be messy with the cement slurry that tends to spew out. The holes are about the size of a soda can and can be unpleasant to the overall appearance. Mudjacking also allows water to seep back into the concrete causing the issue to be reoccur over time.
3. PolyRenewal™ it!
Peak Structural offers a new way of fixing concrete without the mess, hassle, and soda size holes that replacing the concrete or Mudjacking create. We fix sinking concrete with PolyRenewal™. PolyRenewal™ is the method in which it takes the concept of Mudjacking and combines it with modern technology. Instead of using concrete and mud, Polyfill, or polyurethane, is created with high-density polymers that will raise the concrete to the level that is desired. Holes that are smaller than a penny are drilled into the concrete and the specialized equipment is used to inject the polyurethane into the hole. After the void underneath is filled, the polyurethane expands and hardens to allow for a precise lift and stabilization where water cannot seep in and destroy or wash out the fill that has been placed. Overall, PolyRenewal™ will create smaller and fewer holes in your flooring, it is lightweight and dries and ready to be walked/drove on within 15 minutes, it is waterproof, economically friendly, and allows the adjustment to be done precisely.
PolyRenewal™ is the new Mudjacking. It is cleaner, quicker, and an environmentally friendly product that will last longer than any other method.
