IllustrativeConcrete Leveling Warranty & Service Policies
PolyJacks backs every concrete leveling job with a 5-year limited warranty: if a slab we lifted settles more than 1/2 inch below its corrected level within 5 years, under normal conditions and with the homeowner's water-management responsibilities met, the crew returns and re-levels it at no charge. The warranty is issued to the owner who paid for the work at that address and is not transferable. It reflects confidence in waterproof polyurethane foam, which doesn’t wash out or break down underground.
Our Concrete Leveling Warranty, in Plain Terms
When we lift a slab, we stand behind it with a 5-year limited warranty. Here's the promise, no fine-print maze: if any slab we lifted settles more than 1/2 inch below its corrected level within 5 years of the work, under normal conditions and with the homeowner responsibilities below met, we come back and re-level the affected area at no charge. No trip fee. No re-inspection fee. No arguing.
Who it covers. The warranty is issued to the property owner named on the invoice, at that service address. It is not transferable: it does not pass to a new owner if the property is sold, and it cannot be assigned to anyone else. If you buy a house we've worked on, call us anyway. We'll look at the slab for free and tell you where it stands.
We're a locally owned crew based in Spring Hill, and we don't disappear once the truck pulls out of your driveway. One call to (913) 713-7794 and we get you back on the schedule.
What's Covered
The warranty covers the slab staying at the level we set. If a slab we lifted drops more than 1/2 inch below its corrected level within 5 years, the re-level is free. That includes the foam, the labor, and the trip out. There is no materials surcharge for a warranty re-level.
We measure to that half-inch line for a reason: concrete shifts a little with Kansas City's freeze-thaw winters and clay soil no matter what you do, and the trigger has to sit above that everyday movement. A slab settling back down because the lift gave way is a warranty issue.
Half an inch on a public sidewalk is a different number. The 2010 ADA Standards (Section 303) allow a vertical change of up to 1/4 inch on an accessible route, require a bevel between 1/4 and 1/2 inch, and treat anything over 1/2 inch as a ramp; many city sidewalk programs and HOA inspections act at a half-inch offset. Those are code thresholds for public walkways and accessible routes. Our half-inch trigger is a separate thing: a warranty term for the slabs we lift. If a slab we leveled has dropped less than 1/2 inch and you want it flush again, or an inspector measures a public walk against a stricter line, we will still come out, measure it, and quote the re-level as paid work. Call us either way. We'd always rather look than have you wonder.
What's Not Covered and Why
We're upfront about the limits, because a warranty that promises everything protects nothing. This warranty covers the slab staying at the level we set. It does not cover forces that move the earth itself, or anything outside the work we did.
Water and soil
- New or active plumbing, sewer, irrigation or pool-line leaks
- Soil washout or erosion from downspouts, grading, sump discharge or surface runoff that was not corrected
- Flooding, storm events, sinkholes, earthquakes, landslides
- Expansive-soil heave, frost heave, or drought shrinkage beyond normal seasonal movement
- Uncompacted or organic fill placed by others, and voids caused by decaying buried material
- Tree roots, tree removal, or stump decay beneath or beside the slab
The slab and the site
- Slabs, or portions of slabs, outside the zones listed on your invoice
- Pre-existing cracks, spalling, flaking, discoloration and surface condition. Leveling restores height; it is not crack, surface or cosmetic repair
- Slabs already structurally failed, severely deteriorated, or broken into multiple free-floating pieces
- Movement of a slab that was more than 3 inches out of level at the time of service, where we noted the settlement as severe on your invoice
- Loads beyond normal residential use: heavy trucks, dumpsters, RVs, machinery, construction traffic
- Excavation, utility work, landscaping, pool or addition construction, or any later work by others that disturbs the slab or the soil beneath it
- Foundation, footing, structural or geotechnical conditions. This is slab height correction, not foundation repair
Every one of those comes down to the same idea: we can only warranty what we control. We control the lift. We don't control your gutters, a neighbor's oak tree roots, or a freak storm — the usual suspects behind sinking concrete in Kansas City. If one of those is behind a slab moving again, we'll still come out, show you what we found, and give you a free estimate on fixing it right.
Why We Can Promise Five Years
The material under your slab is closed-cell structural polyurethane, the same family of material used under highways and warehouse floors. It is waterproof, it does not shrink, rot or wash away, and it reaches roughly 90% of its strength within minutes of injection. We install a measured quantity computed from your slab's actual surveyed geometry, not a guess. When the ground under it behaves, it has no reason to move. The lift itself is permanent.
What actually threatens a leveled slab down the road is the same thing that sank it in the first place: water finding its way underneath, poor compaction on a newer slab, or roots pushing soil around. Polyurethane holds the slab up. It cannot stop water from washing the soil out from under it. Nearly every slab that settles twice does so because water was still being delivered underneath it.
That is why the five years come with a short list of conditions, all of them about water. Handle those and there's no reason a leveled slab shouldn't stay level for years past the warranty period.
Your Part: Seven Conditions That Keep the Warranty in Force
Coverage depends on these staying true for the life of the warranty:
- Roof water goes away from the slab. Gutters kept clear, and downspouts discharged a minimum of 5 feet beyond the edge of any slab we lifted: extensions, splash blocks or buried drain lines
- Grading slopes away from the slab and the foundation. No ponding or standing water against or beside the concrete after a normal rain
- Irrigation and sprinkler heads are not spraying the slab edge or saturating the soil beside it
- Plumbing, sewer, irrigation and pool lines are sound. Any leak found on the property is repaired promptly; a leaking line under a slab will undo any lift, ours or anyone's
- Joints and open cracks are kept sealed so surface water cannot run straight down into the base
- Normal residential loads only: passenger vehicles and light trucks on a residential driveway
- Any drainage or grading correction we recommended in writing is completed within 60 days. If we told you water was the cause and it was not addressed, the affected area is not covered
When coverage is void. Coverage on an affected area is void if water was not directed away from the slab as described above; a recommended drainage or grading correction was declined or left incomplete beyond 60 days; a known leak was left unrepaired; someone other than PolyJacks injects, lifts, mudjacks or otherwise works the slab or the soil beneath it; the slab is used outside normal residential loads; or the invoice for the original work remains unpaid.
None of this is complicated. It's the same stuff that would've kept the slab from sinking in the first place, had it been caught sooner.
Filing a Warranty Claim
1. Tell us. Call or text (913) 713-7794, or reach us through the site, within 30 days of noticing the change and inside your warranty period. Keep your invoice; it identifies the covered zones.
2. We look. We inspect and re-measure the slab against the level we set, within 10 business days of your call. You provide reasonable access to the slab and to the drainage around it.
3. We fix it. If it is covered, we schedule the re-level promptly and do it at no charge. If the cause is something on this page, we show you what we found and quote the fix.
Selling the house? The warranty ends when the property changes hands; it is written to the owner who paid for the work. Pass along our number anyway. The new owner can call us for a free look at any time.
The Legal Part, Kept Short
This limited warranty is provided by PolyJacks to the property owner at the service address on the invoice, effective on the date of job completion, for a period of five (5) years, and is personal to that owner: not transferable or assignable, terminating on sale of the property. Our responsibility under this warranty is to re-level the affected area as described above, and that is the remedy this warranty provides. PolyJacks is not liable for incidental or consequential damages arising from the leveling work. Concrete leveling is height correction of existing slabs; it is not foundation or structural repair, and no warranty is made regarding soil behavior. Coverage is conditioned on the homeowner responsibilities stated above.
Nothing here limits any right you have under state law. In Kansas, implied warranties cannot be disclaimed, and this warranty does not attempt to. It gives you specific rights in addition to those, and the same term, threshold and conditions appear on the warranty certificate issued with every completed job.

Frequently asked
What exactly does the PolyJacks warranty cover?
If any slab we lifted settles more than 1/2 inch below its corrected level within 5 years of the work, under normal conditions and with the homeowner responsibilities met, we come back and re-level the affected area at no charge: no trip fee, no re-inspection fee. It's a 5-year limited warranty issued to the property owner named on the invoice, at that service address.
How can PolyJacks offer a 5-year warranty on concrete leveling?
Because the material doesn't move. Closed-cell structural polyurethane is waterproof, doesn't shrink or wash out, and reaches roughly 90% of its strength within minutes; we install a measured quantity based on the slab's surveyed geometry. What sinks a leveled slab again is water washing soil out from under it, so the five years come with a short list of water-management conditions. Meet those and the promise holds.
What voids or excludes warranty coverage?
The things that move the earth itself: active plumbing, sewer, irrigation or pool-line leaks; soil washout from downspouts, grading or runoff that wasn't corrected; flooding, sinkholes or earthquakes; heave or drought shrinkage beyond normal seasonal movement; fill placed by others; and tree roots. Also slabs outside the zones on your invoice, pre-existing cracks or surface condition, slabs already broken into pieces, loads beyond normal residential use, later work by others that disturbs the slab, and foundation conditions. Coverage on an area is void if water wasn't directed away as required, a recommended drainage fix was left undone beyond 60 days, a known leak went unrepaired, someone else worked the slab, or the original invoice is unpaid. If one of those turns out to be the cause, we'll still show you what we found and quote the fix.
Does the warranty cover cracks in the concrete?
It covers settling of the slab we lifted, not pre-existing cracks, spalling or surface condition, and not cosmetic or hairline cracking that doesn't affect how level it sits. Leveling restores height; it is not crack or surface repair. Concrete cracks over time in Kansas City regardless of who's worked on it, thanks to our freeze-thaw winters.
What do I need to do to keep my leveled slab from sinking again?
Keep gutters clear and downspouts discharging at least 5 feet from the slab, keep the grade sloping away so nothing ponds beside the concrete, keep sprinklers off the slab edge, fix any plumbing or irrigation leak promptly, keep joints and cracks sealed, keep loads to normal residential use, and complete any drainage correction we recommend in writing within 60 days. Those are the same conditions that sink concrete in the first place, and they are what keeps the warranty in force.
How do I request a warranty re-lift?
Call or text (913) 713-7794 within 30 days of noticing the change and inside the 5-year period. We inspect and re-measure the slab within 10 business days, and if it's covered we schedule the free re-level. Keep your invoice; it identifies the covered zones.
Does the warranty transfer if I sell the house?
No. It is issued to the property owner named on the invoice, at that address, and it ends when the property is sold. It can't be assigned to anyone else. A new owner is welcome to call us for a free look at the slab at any time.
Is settlement under half an inch covered?
Not under the warranty, which starts at 1/2 inch of settlement below the level we set. Accessible-route standards are stricter for public walkways: the 2010 ADA Standards allow only 1/4 inch unbeveled, and many sidewalk programs act at a half-inch offset. Those are code lines for public paths, not the warranty trigger for the slabs we lift. If a slab we leveled has dropped less than 1/2 inch and you want it flush again, we'll come measure it and quote the re-level as paid work.
