Before I write these articles, I spend a little time on Google. Spacing, roughly related to slab thickness, determines the total number of holes.

The thicker the slab, the farther apart you can drill the holes. In most operations, the holes are drilled three to eight feet apart, but no closer than 1 foot from the edge of the slab.

Unless there's a reason not to, holes should be drilled at distances approximately equal from each other. Some experienced contractors are adamant that the size of the hole is very important, others it may matter very little as long as it gets the job done so the smaller the better. The usual range is 1 inch in diameter at the low end of the spectrum, and a maximum of 2 inches in diameter at the upper end. Pumping the grout should begin at the lowest point of the slab, on most jobs.

At the areas in which the grout will do the most lifting, a heavier grout is used. The operator moves from hole to hole as the slab rises about inch to inch. He then moves back and repeats the process. Additional holes may have been drilled as "support" holes, to be filled in order to support the slab as it rises. These holes usually are filled with a less dense, more fluid grout, so it flows easily into the smaller voids. This is the final step in the slabjacking process. First, any remaining grout in the drilled holes is removed.

The holes are then filled with a stiff mortar mix, striking the surface off cleanly. Remember that patched holes are often the most noticeable feature of a lifted slab, but they can be made less noticeable by drilling cores instead of holes, coding the cores, and gluing then back into the same holes after slabjacking. However, this process is much slower, and thus more expensive. Make sure to keep all equipment in good working order and regularly maintained.

Equipment failure during the slabjacking operation can result in project complications. Grout mixers are often the weak link in the operation, causing a great deal of maintenance problems and downtime. They are most often high-speed colloidal shear mixers or the equivalent, being capable of producing a consistent and homogeneous mixture free of lumps.

Smaller jobs may require only a mortar mixer to adequately mix the grout.
