Slab Jacking
Slabjacking, also known as mudjacking, and sometimes referred to as pressure grouting, is a specialist concrete repair method, it attempts to life sunken or settled concrete by pumping a grout through it, in essence this grout pushes the concrete slaps up from underneath in an attempt to level and settle it!
The process of slabjacking is pretty straightforward, and similar techniques date back to the early 1900's, as mentioned, small holes are drilled in to the concrete that is in need of repair, these holes are strategically located by the technicians working on leveling the concrete in order to maximize the lift from the grout underneath.
Once these small diameter holes are located and drilled, an initial material will be injected to fill the void underneath the slabs, once this has been done the grout will then be pumped through the holes thus lifting up the slabs to a level state, this leveling happens literally within minutes of the grout being injected.
As the concrete is lifted and leveled off, the holes that were drilled to allow access to the grout are filled in and patched up, leaving the concrete level and looking brand new.
The process of slabjacking works rapidly and is a major alternative to ripping out the existing damaged concrete and replacing it.
However the process does have some limitations, especially if the concrete that the access holes are being drilled in is thin or brittle, which could cause the concrete to crack either when drilling or from the pressue of being lifted when the grout is injected.
