Warehouse Floor Repair in Spokane, WA
Lift settled interior slabs under racking, forklifts, and heavy equipment with polyurethane foam — most jobs finish in a shift, and the floor is back in service the same day.

Overview
Warehouse Floor Repair for Spokane properties.
A warehouse floor is a working surface. When a slab drops even a quarter of an inch, forklift operators feel it, racks fall out of plumb, and pallet jacks start hanging up on the offset. Left alone, a dropped panel almost always gets worse — repeated wheel loads pump water into the void, fine soils wash out, and the settlement accelerates.
For most Spokane warehouses, the underlying concrete is still structurally sound. The problem is the base beneath it. Polyurethane foam injection targets exactly that: a lightweight, water-resistant material is injected through dime-sized holes, expands under the slab, fills voids, and lifts the concrete back to grade. No demolition, no cure time, no shutdown of the entire building.

What we solve
Warehouse Floor Repair challenges we address.
Slabs under active racking
We identify which sections can be lifted with racking in place and which need short staging windows, and we sequence work by aisle so operations keep moving.
Forklift traffic and dock plates
Foam cures fast enough that most lifted zones handle forklift traffic within an hour, so dock lanes rarely stay closed past a single shift.
Freeze-thaw at exterior dock aprons
Spokane winters drive water into joints at loading zones. We look for washout paths and downspouts during the walkthrough and address root causes, not just symptoms.
Uneven floors under manufacturing tolerances
Where floor flatness matters for equipment or automation, we set laser reference points before lifting so the finished surface hits the tolerance you need.
Process
How the repair runs on site.
Designed to fit around business operations, tenant access, and public pedestrian traffic.
- 01
Facility walkthrough
Meet with your facilities lead, map settlement, review racking layout, forklift routes, and operating windows.
- 02
Written scope
You receive an itemized estimate with staging plan, insurance certificate, and target completion window.
- 03
Small drilled ports
Dime-sized ports are drilled in a planned pattern — controlled, quiet, and low-dust.
- 04
Foam injection & lift
Two-part polyurethane expands beneath the slab, fills voids, and lifts the concrete under laser reference.
- 05
Same-shift return to service
Ports are patched and the floor is released to normal forklift and rack traffic — typically within hours.
Benefits
Why property teams pick leveling here.
No demolition
The original slab stays intact. No jackhammers, no debris, no fresh pour to cure.
Same-day traffic
Polyurethane reaches working strength quickly, so forklifts and racks are back in service the same shift.
Section-by-section staging
Work runs aisle by aisle to fit shift schedules, receiving windows, and 24/7 operations.
Fraction of replacement cost
Typical warehouse floor repair runs a fraction of the cost of demoing and repouring — with no lost operating days.
Water-resistant fix
Polyurethane doesn't wash out and doesn't add hydrostatic load like heavy slurry alternatives.
Certificates of insurance
COIs, safety plans, and PPE coordinated with your risk team before day one.
Frequently asked questions
Questions we hear from property managers and public-works teams.
- Can you lift a warehouse floor while racking is loaded?
- In many cases, yes — the injection pattern is planned around rack posts and load paths. Where a section cannot be safely lifted loaded, we sequence the work so racks are relocated one bay at a time rather than clearing the whole building.
- How much lift is realistic on a warehouse slab?
- Polyurethane foam can typically bring a settled slab back to within a small fraction of an inch of its original grade. On very deep settlement or badly compromised sub-base, we may recommend a hybrid approach — we say so in the estimate rather than promising a lift the slab can't hold.
- Will the ports show on my finished floor?
- Injection ports are roughly dime-sized and patched with color-matched grout. On a working warehouse floor they are visible on close inspection but are not a trip hazard and do not affect forklift or pallet-jack traffic.
- How long does the repair last?
- Polyurethane foam is a stable, water-resistant material. When the underlying drainage or washout issue is addressed at the same time, warehouse floor lifts routinely last for many years. We diagnose root causes during the walkthrough so the same panel doesn't drop again.
- Do you work after hours or on weekends?
- Yes — 2nd shift, 3rd shift, and weekend work are common on active warehouses. Scheduling is part of the estimate.
- Is polyurethane better than mudjacking for a warehouse floor?
- For most warehouse applications, yes. Polyurethane is lighter (so it doesn't add load to a marginal sub-base), the injection holes are smaller, and it doesn't wash out like a cement slurry. See the Learning Center comparison for details.
