Concrete Slab Leveling in Manor, TX
Slabs in Manor sink where clay shrank away or runoff washed soil from beneath. Polyurethane foam is injected through small holes to fill voids and raise the slab. It is lighter than a cement slurry, which suits soft clay, and it cures quickly. We look for the water source so the slab does not settle again. A few test holes reveal how deep and wide the void runs under the Manor slab.
Concrete Slab Leveling for Manor homes
Concrete slabs sink when the soil under them loses support. In Manor, clay can do this in two ways. In wet months the clay swells and may lift a slab unevenly. In dry months it shrinks and leaves voids. Water running under a patio or garage apron can also wash away fine soil. Either way you end up with a slab that tilts, rocks or traps water against the house. Concrete leveling fixes it by filling the void and raising the slab back to its original height. A quick test is to roll a ball or pour a cup of water across the slab. If it runs toward the house or sits in a dip, leveling may fix the slope along with the height.
Today most leveling uses polyurethane foam or cement slurry. Slurry, called mudjacking, is a heavy mix pumped through larger holes. Foam is lighter, goes in through small holes, and sets within minutes. Foam costs more per square foot in most markets, and prices vary a lot by site, so treat any range you read as general information and not a quote. For Manor soils, a lighter material is a plus because the clay is already stressed by moisture swings. The material is only part of the answer, though. If water keeps washing under the slab, the void comes back. Foam injection starts with small holes, often about the size of a dime, drilled at set spacing across the low area. The crew lifts in steps and checks height with a laser or straightedge. Holes are patched with a color-matched grout.
That is why we look at drainage first. A patio that sinks near a downspout needs the downspout moved. A slab that dips beside a swale needs the swale fixed. Leveling also has limits. If the main house slab has moved, call a structural engineer. We level patios, porches, garage aprons, pool decks and walks, not the foundation of the home. Many Manor slabs are fairly new, so low spots from builder fill settling in the first several years are common and often respond well to leveling. Mudjacking can suit large, heavy slabs where the added weight is not a concern, and the lower material cost helps on big areas. We talk through both and explain why one may fit your slab and soil better than the other.
What to know in Manor
Settling in newer fill
Many Manor lots were filled and graded for building. Fill that was not compacted well can settle for years. A slab that dropped an inch in two years may keep moving. Leveling helps, but fixing the water that feeds the settling matters just as much as the lift itself. Photograph the cracks and low points before work so you can compare afterward.
Foam versus mudjacking
Foam is lighter, cures fast, and uses small holes. Mudjacking uses a heavier slurry and larger holes, and it usually costs less. Both can work. Ask what is going under your slab and why that material suits the soil and the load it has to carry. Both methods can work on a slab with good concrete, so ask about the base and soil conditions.
Know the limits
Leveling will not fix a shattered slab or a deep soil failure. If a section is badly cracked or crumbling, replacement may be the better choice. For movement in the main house slab, hire a structural engineer or foundation specialist rather than a concrete leveling crew. A crew that cannot explain why the slab sank is guessing, so ask for their read on the cause.
Signs you may need concrete slab leveling
- Water puddling on a slab that used to drain
- Gaps between the slab edge and the soil or the house
- Trip hazards that catch toes or cane tips
- Cracks running across a settled section
How concrete slab leveling works
Leveling does not solve every problem. If the cause of the settlement is still active, the slab can drop again. A downspout dumping next to a patio, a broken irrigation line, or runoff flowing under a walkway will keep eroding the base. That is why leveling is best paired with drainage work. Extending the downspout, regrading the bed, or sealing the joint where water enters is often what makes the lift last. Slabs also differ in condition. Concrete that is badly cracked, crumbling or thin can break when lifted. In those cases, replacement may be the honest recommendation. We check the slab before quoting, tap it for hollow sounds, and explain the risks so you can choose with eyes open.
One firm boundary: we level exterior slabs that are separate from your house, such as patios, sidewalks, steps, pool decks, and driveways. We do not lift the house slab or do structural foundation repair, which includes piers and slab jacking under the home. Mudjacking and foam can only lift slabs that are not structurally attached to the foundation of the house, and lifting a house calls for engineering. If a patio is tied to the house with rebar, or if you see cracks in interior floors and walls, stop and get a structural engineer or a foundation repair company to look first. They can tell you whether the movement is cosmetic or serious, and our work is then planned around their findings.
What to expect on a Manor visit
- 01
Inspect the slab and the cause
We look at slab thickness, cracks, joints and how far it has dropped. We also trace the likely cause, such as a downspout, irrigation leak or low ground, because a slab will settle again if the water problem remains. Photos and a quick level reading are taken, so we can show you exactly how much lift the slab needs.
- 02
Mark injection points
The slab is mapped, and we mark a pattern of small drill locations based on size and the amount of lift needed. Foam holes are small, usually about five eighths of an inch, so the pattern is less noticeable than a mudjacking layout. Hole spacing is usually tighter near edges and corners, where slabs sag most, and wider across the middle.
- 03
Drill through the slab
We drill the marked holes straight through the concrete into the void below. Dust is controlled, and we protect nearby landscaping and finished surfaces. Holes are kept clear of rebar, post-tension cables and known utility locations. A hollow tap test before drilling tells us where voids sit, which helps us avoid drilling over solid soil.
- 04
Inject in small stages
The expanding foam is injected slowly while we watch the slab. We use levels and string lines to track the lift, working in small steps so one corner does not jump ahead of its neighbor and crack the concrete. Foam expands as it reacts, so the amount is metered carefully, and we stop the moment the slab reaches grade.
- 05
Check the grade and joints
Once the slab is at the target height, we confirm it drains the right direction and that joints line up. A slab raised too far can trap water or create a new lip, so we measure before moving on. Water should run off the slab toward the yard, never toward the house, so we confirm that direction by pouring a bucket across it.
- 06
Patch, clean and review
Holes are filled with a non-shrink patch, and the work area is cleaned. We explain the cure window, what to watch over the next few weeks, and which drainage fixes will help protect the lift. Plan on avoiding heavy loads like furniture sets or planters for the stated cure window, even if foot traffic is allowed sooner.

Soil and drainage conditions around Manor
Local rules matter. Many Manor neighborhoods have HOAs with approval processes, and some lots sit on recorded drainage easements where changes may need city review. We cannot state the City of Manor's grading and permit requirements, so contact the city and your HOA before you start. Texas Water Code Section 11.086 makes it unlawful to divert or impound natural surface water so that it damages a neighbor's property, so your drain outlet should go to the street, a proper swale or an approved point. If a dispute develops, see an attorney. Texas law also requires everyone, homeowners included, to contact Texas811 at least two business days before digging. With gas, water, electric and fiber lines being added as Manor grows, that call is worth making every time. Keep your approval letters and 811 ticket number together in one folder so you can show them if a neighbor or the city asks.
Concrete Slab Leveling questions from Manor homeowners
How long does concrete leveling take?
Most patios, walks and small slabs take a few hours once the crew is set up. Foam cures in minutes, so you can use the slab soon after. Slurry usually needs more time to cure. Larger areas, such as a long driveway, may take part of a day to finish. Plan on keeping vehicles and heavy items off a leveled slab for the time your crew recommends.
Why is my Manor patio sinking?
Common causes are poorly compacted fill, water washing soil out from under the slab, and clay that shrinks in dry weather. Check the nearest downspout and the grade beside the slab. If water runs under it during rain, fix that first or the slab will sink again after leveling. A small water test with a hose near the slab edge can show where runoff goes and where it digs out soil.
Is foam leveling better than replacing the slab?
Often it is less disruptive and cheaper, if the slab is in good shape. Leveling keeps the existing concrete and raises it. Replacement makes sense when the concrete is badly broken or when the base is failing. A site visit is the best way to judge which one fits. If you are unsure, ask for a site visit and a written scope before committing.
Will the slab sink again?
It can if the cause is still active. Leaking downspouts, irrigation lines and runoff under the slab keep eroding the base. Foam resists washout better than cement slurry, but it does not cure a water problem. Fix the drainage and the lift is more likely to last. A gutter extension is cheap compared with repeating the lift, so many owners fix it at the same visit.
Is leveling cheaper than replacing the slab?
Often, but not always. Leveling avoids demolition, hauling and new concrete, so it is commonly less expensive than replacement for sound slabs. If the concrete is crumbling or badly cracked, replacement may be the better value. Costs vary by site, and a general market range is not a quote. Ask for photos of the slab edges so you can judge condition before choosing between lifting and replacing.
Will the drill holes show?
Foam holes are small, about five eighths of an inch, and are filled with a patch afterward. The patch may look slightly different in color at first and tends to blend over time. Mudjacking holes are larger, so they are usually more noticeable. Color matching is not exact, and some owners later brush on a concrete stain or sealer to even out the look.
