High-Density Polyurethane Concrete Lifting (Polyjacking) in Minneapolis

When structurally sound concrete driveways, garage aprons, front walkways, pool decks, or warehouse floor slabs in Minneapolis (55401, 55402, 55403, 55404, 55405, 55406, 55407, 55408, 55411, 55412, 55413, 55414, 55415, 55416, 55417, 55418, 55419) sink due to sub-base washout or soil consolidation, full tear-out isn't always necessary. Our Minneapolis Concrete Pros MN 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 Hennepin 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 Minneapolis 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 Minneapolis 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 North Loop Warehouse District, Mid-City Industrial Park (NE Minneapolis), Downtown Skyway Core, Seward Industrial Park, North Riverfront Industrial Corridor, Towerside Innovation District

Forklifts driving across rocking or spalled floor joints in North Loop Warehouse District, Mid-City Industrial Park (NE Minneapolis), Downtown Skyway Core, Seward Industrial Park, North Riverfront Industrial Corridor, Towerside Innovation District (I-94, I-35W, I-394, MN-55 (Hiawatha Ave), MN-62 (Crosstown), MN-65 (Central Ave NE), Washington Ave, Hennepin Ave, Lake St, Broadway St NE) suffer costly solid-tire and mast damage.

Frequently Asked Questions: Polyurethane Concrete Lifting, Slab Leveling & Joint Sealing in Minneapolis, MN

Why is polyurethane foam concrete lifting better than traditional mudjacking in Minneapolis?

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 Minneapolis 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.
