Slabjacking Might Be The Best Way To Repair Your Foundation
Changing conditions in the soil can cause your foundation to shift. This might happen during a drought when the soil becomes dry and compacted or during a period of unusually heavy rain. When the foundation shifts, you may notice certain signs, like your windows are difficult to slide open and the doors don't fit in their frames. You may even see cracks in your basement wall or see sunken areas and cracks on the basement floor. Foundation problems can be serious, so you want to call a contractor to assess the situation. While the problem may seem dire, the fix may be simple. Slabjacking, or mudjacking, is one quick way to raise a sunken foundation. Here's some information on how it works.
How Slabjacking Repairs Your Foundation
The sunken slab is lifted by pumping a slurry mixture underneath it. The contractor drills holes in the floor that penetrate the concrete and go all the way into the soil. The slurry is then pumped into the holes. The mixture can be made from a variety of materials such as fly ash and concrete or concrete and limestone. The mixture is soft and pliable like mud so it flows along the top of the soil to fill in the void that allowed the slab to sink. When the void is filled, the slurry puts pressure on the slab to make it slowly lift back into place. Once the foundation is level again, the holes are filled with patch concrete and the repairs are done.
The Advantages Of Slabjacking
While there are different approaches to foundation repair, slabjacking has some advantages. For one, there is little mess from concrete dust since the concrete itself is not cut away. Only a few holes need to be drilled. Also, the repaired are can be walked on right away since the surface of the concrete is dry. The slurry underneath the slab will slowly cure, but it won't be bothered by foot traffic above.
Slabjacking is a convenient form of foundation repair when you have furniture or storage boxes in your basement because you don't need to clear out the area. The pressure of the mixture lifts up the slab even if there is furniture sitting on top of it. You won't need to leave your house for the process either. Although there will be a crew working, you'll be disrupted as little as possible.
Slabjacking might not be suitable for all types of foundation repair problems, but it does an excellent job of lifting sunken areas of concrete. The repairs are nearly invisible since all the slurry passes under the slab. You might see where new concrete filled the drill holes, but there won't be an ugly repair patch left on your floor.
