Can Epp work nights or weekends to keep our facility operational?

Yes. Most commercial projects in Epp's territory get scheduled around operations. Foam crews work in 200- to 800-square-foot sections per shift, making sectional shutdowns practical. Slab pier crews work full-day or weekend installs. The repair plan identifies the schedule windows up front so production can plan around them.

Do you work with structural engineers on commercial projects?

Yes. When load class, building code, or warranty requirements dictate, Epp coordinates with the building's structural engineer (or brings one in) to produce a stamped repair plan. Engineer-of-record sign-off stays with the engineer; Epp's scope is execution against the engineered plan.

How fast can a forklift use a slab after polyurethane foam repair?

Foam reaches full load capacity in roughly 15 minutes after injection. A forklift can typically run on the repaired slab within an hour. The slower variable is the joint and crack seals. Polyurethane caulk and epoxy are full-cure in 24 hours. Epp schedules sealing to fit production timing.

Common Commercial Concrete Situations and What Each One Means

Commercial concrete repair matches the method to the load class and the operating schedule of the facility, using polyurethane foam for light to medium load areas and slab piers under heavy forklift lanes or racking. It fits a commercial slab that carries operational or liability risk from settlement, and it stops short of slabs that have failed across most of the area or exceed lift-and-seal capability.

Warehouse aisle settlement under forklift traffic: CauseHeavy forklift traffic on slabs poured at 6 to 8 inches with light reinforcement causes joints to fail first, then radial cracks open from the joint corners.What it meansA forklift catching a 1/2 inch lip in a warehouse aisle is a workers-comp exposure, not just a maintenance item.Repair pathPolyurethane foam injection for light-to-medium load areas, scheduled in 200 to 800 square foot sections per shift.
Loading dock out of level: CauseDifferential settlement of the dock approach slab, often on graded fill that has consolidated over decades.What it meansA dock that has dropped out of level creates a truck-trailer mismatch at the door.Repair pathFoam or slab piers depending on load class, set out in a written repair plan with a structural engineer where warranty or code review requires it.
Retail floor with a settled corner: CauseSettlement at a customer-facing floor, where aesthetics and slip-and-fall risk drive repair priority as much as load capacity.What it meansA settled corner on a retail floor is a slip-and-fall exposure.Repair pathPolyurethane foam injection for light load areas, scheduled around store hours.
Racking footing or forklift lane needing underpinning: CauseZones under heavy forklift traffic, racking footings, or loading-dock approach slabs where settlement has recurred after prior repairs.What it meansThe soil cannot reliably support the load going forward, which is different from a slab that is simply sound but settled.Repair pathSlab piers underpin the slab to load-bearing strata, decided after a site walk and load assessment with a structural engineer where appropriate.

CH 01

Commercial Concrete Repair Is a Different Job Than Residential

A warehouse forklift loads a slab at 4,500 to 12,000 pounds per axle. A retail tenant can't close the floor for three days. A loading dock has to be operational by 5 a.m. Monday. Epp Foundation Repair built its commercial division around those realities: engineered repair plans, load-class-appropriate methods, and scheduling that works around the operation. Not the other way around. Dave Epp founded the company in 1994 and has personally walked commercial sites across Lincoln, Omaha, Council Bluffs, Kansas City, and St. Joseph. The pattern at the commercial scale is the same as residential. Soil moves, slabs follow, but the consequences are different. A forklift catching a 1/2-inch lip in a warehouse aisle is a workers-comp claim. A loading dock that drops out of level by 3/4 of an inch is a truck-trailer mismatch. A retail floor with a settled corner is a slip-and-fall. The repair scope has to match the operational risk.

CH 02

Where Epp Sees Commercial Concrete Failures in This Region

Five commercial site types account for the majority of Epp's commercial work in NE/IA/KS/MO: 1. Lincoln Air Park and west Omaha warehouses on engineered fill. Industrial parks built on graded fill from the 1970s and 1980s settle differentially as the fill column consolidates over decades. Aisle lifts and joint repairs run 1,000 to 5,000 square feet at a time. 2. I-680 and I-29 corridor distribution and food-grade facilities. Heavy forklift traffic on slabs poured at 6 to 8 inches with light reinforcement; joints fail first, then radial cracks open from joint corners. 3. Council Bluffs and Bottoms grain-belt storage. Slabs on Missouri River alluvial soils. High water table, fines mobilize under any leak or downspout failure. 4. Sarpy and Lancaster County retail strip center slabs. Customer-facing floors; aesthetics and slip-and-fall risk drive the repair priority more than load capacity. 5. Kansas City and St. Joseph commercial parking lots and loading docks. Expansive clay subgrade combined with heavy truck traffic; lots heave and settle seasonally. ## Methods Epp Matches to Load Class

Epp uses three of the concrete repair methods on commercial slabs, selected by load class and condition: - Polyurethane foam injection for light-to-medium load areas. Retail floors, office space, warehouse aisles under 5,000 pounds per axle. Polyurethane caulk for working joints, epoxy injection for structural cracks crossing the slab. Customized Repair Estimate after on-site inspection, and where appropriate a structural engineer's stamped repair plan. Reflects the actual scope.

CH 03

How Epp Runs a Commercial Project

Four steps from first call to demobilization: 1. Pre-bid site walk and load assessment. Site manager and Epp's commercial inspector walk the affected areas with a laser level, document settlement, and identify load class for each zone. Structural engineer brought in when load class or building code review requires it. 2. Engineered repair plan. Written scope identifies method per zone (foam vs. Slab piers vs. Crack repair), pier count and depth where applicable, schedule windows (night, weekend, sectional shutdown), and any temporary load restrictions during cure. 3. Mobilization on the operational schedule. Equipment, crew, and materials staged to minimize footprint on operations. Foam crews work in 200 to 800 square foot sections per shift; pier crews work full-day or weekend installs. 4. Demobilization and verification. Final laser level confirms grade across repaired zones, crack and joint seals cure overnight, written close-out documents the repair for the building owner's records.

CH 04

What Epp Doesn't Do on Commercial Work

Scope clarity matters more on commercial work than anywhere else. Owners are coordinating multiple trades against an operating schedule. Epp does not: - Do new-construction flatwork or take on new-construction projects. Epp is post-construction repair only. - Engineer-of-record sign-off (Epp coordinates with the building's structural engineer; Epp's scope is execution, not design certification). - Sawcut and demo large slab sections for full replacement (concrete demo contractor). When a commercial slab is beyond repair scope. Failed across most of the area, end-of-life concrete, or load demands that exceed lift-and-seal capability. Epp says so in the Customized Repair Estimate and prices removal and a new pour alongside the repair options.

CH 05

Regional Context: Why Commercial Slabs Move in NE, IA, KS, MO

The four-state territory Epp covers has three distinct subgrade conditions that drive commercial concrete failure: - Loess fills (eastern NE, western IA). Hydroconsolidate 8 to 12% on first soaking; differential settlement across a large slab can reach 2 inches over a single column of fill. - River bottomland alluvium (Missouri River valley from Sioux City to St. Joseph). High water table, low natural density, fines mobilize easily under leaks and concentrated drainage. - Expansive clay (eastern KS, western MO, parts of southeast NE). 15% volumetric swell-shrink on moisture cycling; commercial slabs on clay heave one season and drop the next without proper subgrade management. Epp Foundation Repair holds a BBB A+ rating and is the only foundation contractor in Nebraska to win the BBB Integrity Award twice (2011 and 2016).

Which Solution Is Right?

Which Commercial Concrete Repair Method Fits

Method	Fits when	Not a fit when	Warranty
Polyurethane Foam Injection	Light-to-medium load areas such as retail floors, office space, or warehouse aisles under 5,000 pounds per axle.	Heavy forklift traffic, racking footings, or a zone where settlement has recurred after prior repairs, which need slab piers instead.	5 years from substantial completion, limited to defects in materials or workmanship
Slab Piers	Heavy forklift lanes, racking footings, or loading dock approach slabs where the soil cannot reliably support the load going forward.	The load class is light to medium and the slab is otherwise sound, where foam is the more direct fix.	10 years from installation, stabilization only, no lifting warranty is provided
Crack and Joint Repair	Working joints need polyurethane caulk, or a structural crack crossing the slab needs epoxy injection.	The slab has failed across most of the area, where sectional repair costs more than replacement over the asset's remaining life.	Ask about the warranty that applies to your project

Each method is matched to a specific failure mode and soil profile. Browse the toolkit we draw from when diagnosing your home.

Polyurethane Foam Injection

Epp Foundation Repair has injected closed-cell structural foam beneath driveways, sidewalks, garage floors, and pool decks across Nebraska, Iowa, Kansas, and Missouri since 1994. The slab lifts. The void fills. The work finishes in a single day.

Polyjacking

Epp Foundation Repair has installed polyurethane foam slab lift. Whether the contractor calls it polyjacking, foam jacking, or poly lift. Across Nebraska, Iowa, Kansas, and Missouri since 1994. Same closed-cell foam. Same 5-year warranty.

Slab Piers

Epp Foundation Repair has installed small-diameter helical slab piers under ranch homes, slab additions, and light commercial slabs across Nebraska, Iowa, Kansas, and Missouri since 1994. Engineered for slab-on-grade loads, backed by a 10-year Epp stabilization warranty.

Mudjacking

Mudjacking is the traditional method for lifting a sunken concrete slab: a cement based slurry pumped beneath the slab to fill the void and raise it back to grade. Epp Foundation Repair does not perform mudjacking. Here is how the method works, and why our crews use polyurethane foam injection on every lifting job across Nebraska, Iowa, Kansas, and Missouri.

Slab Jacking

Epp Foundation Repair has slab jacked driveways, sidewalks, garage floors, patios, and pool decks across Nebraska, Iowa, Kansas, and Missouri since 1994, using polyurethane foam injection to lift settled slabs back to grade.

Regional Context

Why concrete fails differently in Nebraska, Iowa, Kansas, and Missouri

Loess soils consolidate under slabs after the first deep water exposure. Expansive clay heaves and contracts seasonally. Salt damage from frequent winter freeze-thaw cycling accelerates surface failure. Generic concrete repair ignores the soil under the slab, which is why settled concrete returns within a season or two. Regional repair starts with the cause underneath, not the crack on top.

Loess soils and the crack patterns they produce

Most of eastern Nebraska and western Iowa sits on wind-deposited loess, a fine, silty soil 10 to 200+ feet deep. Loess holds its structure when dry but loses cohesion rapidly when saturated. After a wet spring, saturated loess expands against foundation walls. After a dry Nebraska summer, it contracts, pulling away from footings, creating voids beneath slabs, and producing the vertical and diagonal settlement cracks we see most frequently on the Lincoln, Omaha, Council Bluffs corridor.

The Marshall and Sharpsburg loess series, dominant across the eastern Nebraska service area, are particularly prone to this cyclical volume change. Homes built in the 1960s, 1980s on uncompacted loess backfill show the highest incidence of progressive settlement cracking in our inspection data.

Frost depth, freeze-thaw cycles, and horizontal cracking

Eastern Nebraska's 36, 42" frost penetration depth means the soil below grade freezes and thaws 60, 80 times per year. Each cycle applies lateral pressure to basement walls. A wall that holds through ten cycles can fail in the eleventh if drainage has worsened, backfill has settled, or the wall was already at capacity. Horizontal cracks near the soil grade line are almost always a freeze-thaw story in this region.

In eastern Kansas, expansive clay pockets near the surface introduce a different failure mode. Consistent volume change regardless of frost depth. Horizontal cracking in Kansas foundations typically traces to clay expansion; the same pattern in Nebraska more often indicates frost-driven hydrostatic pressure.

Customized Repair Estimate after on-site inspection. With structural engineer coordination where required. Reflects your actual scope.

Replace when the slab has failed across most of the area, when load demands exceed lift-and-seal capability (extreme point loads on degraded concrete), when the concrete has reached end of life, or when sectional repairs would cost more than full replacement over the asset's remaining life. Epp's inspector documents the call on the Customized Repair Estimate and prices the replacement pour alongside the repair options.

Epp does not do new construction. The company is post-construction repair only and does not take new-construction projects. On an existing building, Epp lifts and seals the slab that is still sound and pours new concrete where a section has reached end of life, once the failed concrete is removed and the base is corrected. Full-area replacement that needs large-scale sawcut and demolition goes to a concrete demo contractor, and the inspector flags which path fits on the Customized Repair Estimate.

Foam fills voids and lifts settled slabs that are still structurally sound and supporting their load. Slab piers underpin the slab to load-bearing strata when the soil cannot reliably support the load going forward. Heavy forklift traffic, racking footings, loading-dock approach slabs, or any zone where settlement has recurred after prior repairs. Epp's inspector and (where appropriate) a structural engineer make the call after a site walk and load assessment.

When this isn't the right fix

Lift-and-seal is the wrong scope when the slab has failed across most of the area, when load demands exceed the capability of foam or piers on the existing concrete, when sectional repair would cost more than full replacement over the asset's remaining life, or when end-of-life concrete has reached the point that further repair isn't economical. Epp also does not take new-construction projects, sign as engineer-of-record, or perform large-scale slab demo. Those scopes go to design engineers and concrete demo contractors.
