Mudjacking / Slabjacking in Jefferson City, MO

Mudjacking, also known as slabjacking, is a cost-effective process used to lift and stabilize sunken concrete slabs. Instead of replacing your concrete, a specialized grout mixture is injected beneath the slab, filling the voids and lifting it back into place.

Common Causes of Concrete Settlement & Sinking

• Erosion & Soil Washout – Heavy rain and water drainage issues erode supporting soil, causing slabs to sink.
• Expansive Clay Soil – Soil expands when wet and shrinks when dry, leading to uneven concrete settlement.
• Poor Soil Compaction – Improperly compacted soil beneath slabs causes weak support and sinking.
• Plumbing Leaks & Water Intrusion – Excess water beneath foundations weakens the soil and creates voids.
• Heavy Loads & Weight Stress – Parking heavy vehicles on driveways or concrete slabs accelerates settlement.

Mudjacking / Slabjacking Process

At Jefferson City Foundation Repair, we use precision slab lifting techniques to restore uneven concrete:

✔ Drilling Small Injection Holes – Small holes (typically 1 to 2 inches in diameter) are drilled in strategic locations on the slab.
✔ Injecting a Grout Mixture Beneath the Slab – A slurry mix of cement, sand, and water is pumped underneath, filling voids and stabilizing the soil.
✔ Gradual Slab Lifting – Controlled pressure evenly lifts the slab to its original level.
✔ Hole Patching & Surface Finishing – The injection holes are sealed, and the surface is restored for a smooth finish.

This method is quick, non-invasive, and more affordable than full slab replacement.
