Concrete is a heavy material, and so is the cement mixture used to create concrete. Traditional sidewalk repair methods like mudjacking or slab jacking have relied on a cement slurry to attempt to lift and level uneven slabs. However, these methods are outdated, invasive, expensive, and time-consuming. They involve drilling large, soda can-sized holes in the concrete and pumping the cement slurry mix underneath. This mixture does not completely fill the void between the soil and the concrete, it takes several hours and even days to cure, and its weight will cause the underlying soil and slab to sink again.
