X 20  = 400 Cubic yards of grout.

In addition you may have to underpin the house. During this process your home is a disaster area. You do not want to be staying in the house while the Florida sinkholes repairs are being done. After the construction is done the house can continue to shift and crack. Some cracks are gone and some new ones appear. In one of my Pasco homes the floor buckled 30 days after the house was pumped. I had to cut that area out, then install a new floor. It is something to think about if you have a tile floor. You may have to replace the entire tile floor. It is very hard to get tile to match after some of the old ones in the middle brake. Your headaches are not over after the initial construction is done.

Compaction grouting actually fills in the lime rock and pressurizes the soil in the surrounding areas. This increasing the capacity of the soil to hold up the weight of the house.  Compaction grouting does not lift the of the Florida sinkholes house itself. Compaction grouting should normally stop once any lift is noticed on the house. In some cases compaction grouting has been thought to have actually worsened a sinkhole and caused it to grow more quickly because of the added weight.

Underpinning on the other hand is much more precise at lifting. because it can lift at multiple points on the foundation directly at the foundation simultaneously or differentially.

Once a Florida sinkholes has been determined on the
property.  If there is no structural damage, compaction grouting is a better solution.

If structural damage has occurred and lifting is needed. Compaction and underpinning are the best solution! When it comes to Florida sinkholes repair, I find it prudent follow what the engineer recommends and do not cut corners.

Sinkholes are probably safe if a repair has been certified by a licensed engineer. However, as you are dealing with natural systems, there can be no guarantees that a repaired Florida sinkholes will not cause future problems.
