Mudjacking: Concrete Leveling Without Replacement

Over time, driveways, sidewalks, patios, and other concrete surfaces can settle unevenly. Not only does this create trip hazards and drainage issues, but it can also make your property look neglected. Many homeowners assume the only solution is to tear out and replace the concrete—but there’s a faster, more affordable option: mudjacking.

What Is Mudjacking?

Mudjacking, also known as slabjacking or concrete leveling, is a process that lifts and levels sunken concrete without replacing it. Instead of pouring new slabs, a specialized slurry is pumped underneath the existing concrete to raise it back into position.

This slurry mixture—often made from water, soil, sand, and cement—fills the gaps beneath the slab, providing a stable base that restores both safety and appearance.

Why Concrete Sinks in the First Place

Concrete doesn’t just settle for no reason. Common causes include:
  • Soil Erosion – Water washes away the base material.
  • Poor Compaction – Soil wasn’t compacted enough before the concrete was poured.
  • Freeze-Thaw Cycles – Moisture in the soil expands and contracts, shifting the slab.
  • Drainage Issues – Water pooling near the slab undermines the base.

The Mudjacking Process

Most jobs can be completed in a matter of hours, and the surface is ready to use within a short time.

Benefits of
Mudjacking
  • Cost-Effective – Often 50–75% less than replacement.
  • Quick Turnaround – Minimal disruption to your property.
  • Eco-Friendly – Reuses your existing slab and uses natural materials.
  • Long-Lasting – A stable base prevents further sinking.
When Mudjacking Is the Right Choice
Mudjacking is ideal for:
  • Driveways and garage floors
  • Sidewalks and walkways
  • Patios and porches
  • Basement and interior concrete floors
However, if the concrete is severely cracked or crumbling, replacement may be the better option.
Work With a
Professional

While some DIY kits exist, mudjacking requires specialized equipment and expertise to ensure the slab is lifted evenly without causing more damage. At Fort August Construction, we provide full project support—meaning if the uneven concrete has caused damage to surrounding areas or interiors, we can repair that too.
