A cement-based slurry pumped under a slab raises it back to level, a time-tested method for heavy, thick concrete.
Mudjacking, also called slabjacking, has been used for decades to raise sunken concrete. A slurry of cement, sand and water is pumped under the slab through holes drilled in the surface. As the slurry fills the void and builds pressure, the slab rises. When it reaches the right height, the holes are patched and the grout hardens to a stable base.
Because the slurry is heavy, mudjacking suits thick slabs, large voids and projects where the added weight is not a concern. It is also a strong fit when the budget needs to stretch across a large area. We explain the tradeoffs in plain language, since foam is lighter and cures faster while grout costs less per cubic foot of void. We pick the method that suits the soil, the slab and your priorities. Many owners ask which is better, and the honest answer is that both work. The choice depends on the thickness of the slab, the softness of the soil and how soon you want to use the surface again.
We drill holes about the size of a golf ball in a planned grid and pump the mix in under controlled pressure.
The cement-based mix suits large voids and thick slabs, and it hardens to a solid base.
Grout takes longer to cure than foam, so we give instructions on how soon you can drive or walk on the surface.
On very soft soil or where speed is crucial, foam is often the better choice. We help you compare.

You tell us what you have noticed, a crack, a damp smell, a sloping floor or standing water, and we set a visit that fits your day.
We look closely inside and out, measure floors and cracks, check moisture and drainage and take photos of anything of note.
We explain what is urgent, what can wait and what is optional, and give you a written scope and options.
We lay floor protection, mark utilities, protect landscaping and set up before any digging or drilling begins.
We install, seal, lift or repair with the right tools and materials, checking our work as we go.
We clean up, restore the surface, show you what we did, share care tips and set a reminder for your next check.
