Aggregate Jacking in the Greater Minneapolis-St. Paul Metropolitan Area
As property owners, going the DIY route for your next concrete leveling project can be tempting. While some may think it would help them save money, one mistake could turn everything around. When concrete is not prepared, handled, placed, and cured correctly, it can pose safety concerns and be costly to fix or redo.

Our Material (Aggregate Jacking)
Consists of limestone, Quarts, granite fragments, and powderized portland cement, allowing for optimal compaction of the weak underlying soil. Our materials can be thickened or thinned out for each application, to allow proper void/coverage filling with each situation. Our materials will recompact weak underlying soil and take a soild set within 24hrs, making this material the most suitable solution for lifting/void filling projects.
Foam or polyurethane materials are newer to the industry. These materials are man made chemicals that start as liquid and react with air to turn into foam. Foam materials are uncontrollable and could cause Lifting to happen in areas that dont need it. Foam does not fix the weak underlying soil issues due to its lightweight construction, which simply won’t fix the real problem with settling concrete. This material also has problems with filling all the voided areas due to the reaction time with air. Foam can expand too fast not allow correct void filling.
“Mudjacking” materials typically consist of powderized lime, calcium carbonate, or bentonite. These materials can lift settled concrete, but won’t last long due to the non compactable properties these materials consist of. The Mudjacking materials do have alot better void filling coverage than Foam, but never take a solid set, which eventually allows the area lifted to settle back down.
We start by strategically drilling 1 1/8-inch diameter holes in the concrete that needs to be lifted. And then, we’ll hydraulically pump crushed gravel or Portland Cement slurry through the holes, filling all cavities and pushing the slab back to its original grade. After the slab is back in its original place, we clean the concrete surface thoroughly and patch the holes with cement.
The Other Guys
Most local aggregate jacking companies in Minnesota follow the same process but use different materials. One commonly used material is Calcium Carbonate or pulverized rock. This soft, chalky substance will lift slabs but will not stay due to the material’s inability to compact and because Calcium Carbonate is also very vulnerable to water.
Another popular product is Polyfoam. This injectable liquid chemical reacts to air to make foam. It’s proven to be three to five times more costly than traditional aggregate jacking. Due to its liquid form, it can be hard to control in residential settings.
