Concrete raising is a quick, affordable, long-term, and effective means of repairing cracked, sunken concrete. Concrete repair is usually made in minutes or hours, as opposed to the days involved in complete or partial replacement. In most cases, the repaired areas can be used immediately rather than the extensive period of time required for new concrete to set. Raising concrete costs a fraction of replacement, and the repairs are as long-lasting or exceed the expectations of new concrete.
Poor installation (e.g. a poorly compacted soil bed), soil erosion, and naturally shifting earth will all cause concrete to lose its integrity and sink, settle, or crack. The resulting cracks and/or unlevel and unstable slabs are not only unattractive, but also develop into tripping hazards (a liability concern for both home owners and property managers), pooling water, and damage to foundations. Concrete repair through concrete raising can level and repair sidewalks, garage floors, patios, and almost any other concrete expanse in both residential and commercial areas. Surrounding grass, trees, and shrubbery are undisturbed, and landfills are not burdened with old concrete (often categorized as hazardous waste).
The process for raising concrete is straightforward. Small holes are drilled into the existing concrete, then pumped full of slurry under high pressure. Slurry is a cementitious pulverized limestone that fills the voids under the concrete and consequently elevates the slabs. Air pockets, water, and any water saturated materials are displaced with the slurry, raising the slab, and leaving a firm permanent sub-grade that is impervious to water.
