Concrete Leveling & Polyjacking in Des Moines, IA – Slab Lifting
When concrete driveways, sidewalk panels, or patio slabs sink due to soil settlement or washouts, replacement is not your only option. Des Moines Concrete Solutions provides precision geotechnical polyurethane foam concrete leveling (polyjacking). By injecting expanding, high-density polymer foam through tiny penny-sized holes, we raise sunken slabs flush with adjoining surfaces in under an hour—saving you up to 60% compared to full replacement costs.

Concrete Slab Polyjacking & Leveling Placement Protocol
Non-Invasive Polyurethane Concrete Raising
Unlike traditional mudjacking that pumps heavy slurry through large, unsightly 2-inch holes, our polyjacking system utilizes lightweight, closed-cell geotechnical polyurethane injected through small 5/8-inch ports. The foam expands beneath the slab, filling subterranean voids, consolidating weak sub-soils, and lifting the concrete with millimeter precision before curing in 15 minutes.
Driveway & Approach Slab Raising
Lifting sunken panels at the garage threshold, eliminating damaging bumps and vehicle chassis scraping.
Sidewalk Trip Hazard Mitigation
Elevating settled municipal and residential sidewalk panels flush to eliminate liability and code violations.
Pool Deck & Patio Stabilization
Restoring settled pool decks flush with coping stones without disturbing underground plumbing.
Settlement Problems Polyjacking Resolves
Recognize these surface conditions on your Des Moines property. Each represents a common structural symptom caused by freeze-thaw cycles and seasonal moisture movement.
Issue: Dangerous Trip Hazards on Walkways
Engineered Remedy: Lifts sunken edges flush with adjoining panels, eliminating municipal code citations and pedestrian tripping risk.
Issue: Water Pooling Towards Foundations
Engineered Remedy: Re-establishes positive outward drainage slope on patios and walkways, protecting basement walls from dampness.
Issue: Jarring Bumps at Garage Entrance
Engineered Remedy: Levels the dropped driveway slab flush with the structural garage slab, protecting vehicle tires and suspensions.
Polyjacking Hardware & Foam Chemistry
Mix designs, reinforcement materials, and surface protectants formulated specifically for long-term durability in Midwestern climatic extremes.
High-Density Geotechnical Polymer Foam
Closed-cell expanding polyurethane with 4 to 5 lb/cu ft density supporting heavy vehicle loads without degrading.
Hydrophobic Water-Impermeable Properties
Never erodes, washes out, or absorbs subterranean moisture, even in high water table environments.
Color-Matched Port Sealant
Specially formulated concrete patch mortar matching existing slab color to make drill ports virtually invisible.
Properties Ideal for Polyjacking
Engineered concrete work tailored to single-family homes, upscale residential neighborhoods, and light commercial properties.
Residential Homeowners
Driveways, front walks, and back patios that have settled but remain structurally sound without web cracking.
HOA Communities & Property Managers
Fast sidewalk leveling across multi-family developments to satisfy insurance and safety compliance.
Commercial Storefronts & Warehouses
Interior warehouse slab rocking remediation and retail entrance walkway leveling with zero downtime.
Geotechnical Factors in Slab Lifting
Key sub-base, moisture, and load-bearing parameters evaluated during our initial on-site project evaluation.
Sub-Slab Void Identification
Mapping subterranean cavities created by plumbing leaks, downspout washouts, or burrowing pests.
Expansion Pressure Calibration
Controlling injection rates prevents over-lifting and ensures uniform, gentle slab elevation recovery.
Lightweight Advantage Over Mudjacking
Polyurethane adds only 2 to 4 lbs per cubic foot versus 100+ lbs for mud slurry, preventing re-settlement.
Why Des Moines Soils Cause Concrete Sinking
Polk and Dallas Counties feature expansive glacial clay soils that swell dramatically when saturated and shrink during summer dry spells. Additionally, severe winter frost heave followed by rapid spring thaws washes away poorly compacted sub-base sand. Polyjacking solidifies the sub-grade, displacing trapped water and providing an impermeable, permanent base that resists future settlement.
How the Concrete Slab Polyjacking & Leveling Process Works
A clear, disciplined 5-stage progression from initial phone dispatch to final walk-through inspection.
Diagnostic Assessment & Elevation Check
Inspect slab condition, measure drop with digital levels, and confirm the concrete is a candidate for lifting.
Precision 5/8-Inch Port Drilling
Strategically drill small 5/8-inch holes through the concrete slab at calculated lifting points.
Polyurethane Foam Injection
Inject expanding high-density geotechnical polymer using specialized computerized proportioning equipment.
Real-Time Elevation Monitoring
Monitor slab elevation continuously with laser targets until the surface aligns perfectly flush with adjacent concrete.
Port Patching & Immediate Reopening
Clean injection ports, fill with color-matched polymer concrete patch, and open to full traffic in 15 minutes.
Homeowner Preparation for Polyjacking
- ✓Ensure clear access to the sunken slabs (move vehicles, trash bins, patio furniture).
- ✓Make sure downspouts or gutters near the settling area are not actively leaking onto the slab.
- ✓No major demolition or lawn disruption occurs—the entire process is clean and compact.
Polyjacking Investment vs Full Replacement
Polyjacking typically costs 50% to 70% less than complete concrete tear-out and replacement. Pricing is based on the volume of geotechnical polyurethane foam required to fill subterranean voids and lift the slab to proper grade. Estimates are provided on-site with fixed, transparent pricing.

Frequently Asked Questions About Concrete Slab Polyjacking & Leveling
Direct answers to common homeowner questions regarding curing timelines, mix designs, and weather scheduling.
How long does polyurethane foam last under concrete?
Geotechnical polyurethane foam is non-biodegradable, waterproof, and chemically inert. It will never rot, wash out, or degrade, providing permanent sub-slab support for the life of the concrete.
How soon can I drive on concrete lifted with poly foam?
The foam cures to 90% full strength within 15 to 30 minutes. You can drive passenger cars on the leveled slab almost immediately after our crew finishes.
Will the drill holes be visible on my patio or driveway?
Our holes are only 5/8-inch in diameter (about the size of a dime). We patch them with color-matched polymer mortar, making them virtually unnoticeable once dry.
Can all cracked or sunken concrete be leveled?
Polyjacking works best on intact or mildly cracked slabs. If a slab is severely shattered into small spiderweb fragments, replacement is usually the better long-term option. We provide honest evaluations on-site.
Is polyurethane better than traditional mudjacking?
Yes. Polyurethane requires much smaller drill holes, weighs 95% less (preventing re-settlement), cures in 15 minutes rather than 24 hours, and will never wash out from water exposure.
