The first step to mudjacking
is to drill through the concrete in a strategically placed pattern in which the holes are usually somewhere between two to four feet apart, depending on the individual slab or slabs. Our holes are one and three-eighths inches in diameter.
Then our "mud" (see Materials section below) is hydraulically pumped through the holes, filling voids and raising the concrete once they are filled. By changing the amount of mud pumped into different holes, we can achieve the desired grade. When the raising is completed, the holes are thoroughly cleaned and filled with new concrete.
