High-Density Polyurethane Concrete Lifting (Polyjacking) in St. Paul
When structurally sound concrete driveways, garage aprons, front walkways, pool decks, or warehouse floor slabs in St. Paul (55101, 55102, 55104, 55105, 55106, 55107, 55108, 55114, 55116, 55117, 55119, 55130) sink due to sub-base washout or soil consolidation, full tear-out isn't always necessary. Our St. Paul Concrete Pros restoration division injects closed-cell, hydro-insensitive two-part geotechnical polyurethane foam through 5/8-inch ports (half the size of traditional mudjacking holes). Weighing only 4 lbs per cubic foot vs. 110 lbs/cu ft for mudjacking slurry, polyurethane foam lifts slabs with millimeter precision without overburdening weak Ramsey County soils—and is ready for vehicle traffic in 30 minutes.
Expansion Joint & Control Joint Caulking to Stop Winter Frost Heave
Open gaps between driveway panels, garage floor joints, and house foundations act like funnels—channeling thousands of gallons of rain and snowmelt straight into the sub-base beneath your St. Paul concrete. When that trapped sub-base water freezes in January, it heaves and cracks the slab above. We diamond-clean joints, pack closed-cell polyethylene backer rod, and install self-leveling polyurethane (Sikaflex) or ultra-low-modulus silicone (Dow 790/890) joint sealants that stretch 50% to 100% in sub-zero cold.
Polymer-Modified Concrete Resurfacing & Salt-Scaling Restoration
For St. Paul steps, stoops, patios, and walkways suffering from surface salt scaling, pitting, or spalling where the underlying structural slab remains solid, we diamond-grind the deteriorated laitance layer and apply high-bond polymer-modified cementitious overlays (Ardex / Mapei / Euclid Tammscrete) tested for Climate Zone 6A freeze-thaw durability—restoring a clean broom or decorative texture at 40% to 60% less than replacement cost.
Commercial Warehouse Slab Stabilization & Joint Spall Rebuilding in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park
Forklifts driving across rocking or spalled floor joints in Midway Industrial District, Energy Park, Westgate Business Park, Riverview Industrial Park (West Side Flats), Downtown Lowertown & Skyway Core, Red Rock Industrial District, Empire Builder Industrial Park (I-94, I-35E, US-52 (Lafayette Fwy), MN-280, University Ave, Snelling Ave (MN-51), West 7th St (MN-5), Shepard Rd) suffer costly solid-tire and mast damage. We stabilize rocking warehouse slabs via under-slab polyurethane void filling, saw-cut chipped joint edges, and rebuild load-bearing joint nosings with rapid-cure polyurea/epoxy mortar that reopens to forklift traffic in 1 hour.

Frequently Asked Questions: Polyurethane Concrete Lifting, Slab Leveling & Joint Sealing in St. Paul, MN
Why is polyurethane foam concrete lifting better than traditional mudjacking in St. Paul?
Traditional mudjacking drills large 2-inch holes and pumps heavy cement/soil slurry that washes out again during spring thaws and adds weight to sinking soil. Polyurethane foam uses tiny 5/8-inch ports, never absorbs water, weighs 96% less, and cures in 15–30 minutes.
How do I know whether my sunken St. Paul driveway should be lifted or replaced?
If the concrete panels themselves are largely intact (minimal spider-cracking or crumbling) and have simply settled 1 to 4 inches at the garage apron or sidewalk, polyurethane lifting + joint caulking saves 50%–70% over tear-out. If the slab is heavily shattered or scaling, we recommend full replacement.
