Concrete raising, often called mudjacking, is a process used to lift and level sunken or uneven concrete slabs. It involves injecting a mixture, typically made of sand, silt, and clay, underneath the slab to raise it back to its original position.

Mudjacking works by drilling small holes into the sunken concrete slab. A slurry mixture is then pumped under pressure through these holes. As the mixture fills the voids beneath the slab, it lifts the concrete back into place. The holes are then patched, leaving a leveled surface.

Concrete often sinks or settles due to soil erosion, poor soil compaction, water penetration, or the natural settling of the ground over time. Expansive soils that shrink or swell depending on moisture levels can also lead to uneven concrete surfaces.

Concrete raising is generally a long-lasting solution, but its permanence depends on factors like soil conditions, the quality of the slurry mixture used, and future ground movement. While mudjacking can last for many years, extreme soil conditions or poor drainage could cause future settling.

Mudjacking is a repair method that lifts existing concrete slabs, while concrete replacement involves tearing out the old slab and pouring new concrete. Mudjacking is typically faster, less expensive, and more environmentally friendly because it avoids waste.

Not all concrete surfaces are suitable for mudjacking. While it works well for driveways, sidewalks, patios, and garage floors, it may not be ideal for smaller slabs or those that are severely damaged, cracked, or have significant structural issues.

Mudjacking is generally more affordable than concrete replacement. The cost depends on the size of the area that needs to be raised and the extent of the settling. On average, the cost can range from $3 to $6 per square foot, which is significantly cheaper than replacing the entire slab.

The mudjacking process is usually quick and can be completed in a few hours, depending on the size of the area. After the procedure, the surface is often ready for use within 24 to 48 hours, making it a faster solution compared to concrete replacement.

Yes, mudjacking is considered environmentally friendly because it reuses existing concrete slabs and reduces the waste generated by tearing out old concrete. Additionally, the materials used for mudjacking, like sand, silt, and clay, are often natural and non-toxic.

The key benefits of mudjacking include cost-effectiveness, minimal downtime, and the ability to restore the original concrete slab without needing full replacement. It also prevents further damage by addressing issues early, provides long-lasting results, and improves the safety of walkways and driveways.
