Concrete Slab Leveling in Wells Branch, TX
Aging patios, garage slabs and porches in Wells Branch commonly sink where irrigation leaks or roof water washed out the base. Polyurethane foam lifts the slab through small holes and fills the void. Mudjacking uses a heavier cement slurry and larger holes. On soft clay beneath older slabs, the lighter foam adds less load. Filling the void matters as much as the lift, since empty space invites the next sink.
Concrete Slab Leveling for Wells Branch homes
Concrete in Wells Branch is old enough to have a history. Driveways, patios, garage floors and porch slabs poured in the 1980s and 1990s have had decades of wet and dry cycles under them. Clay swells and shrinks, tree roots grow and small leaks wash soil out. The slab on top does not follow neatly, so one side drops. The result is a tilt that sends water to the wrong place, or an edge that catches a toe. Settling often begins at the edges. A patio might drop where it meets the house because the fill beside the foundation was never fully compacted. A driveway might drop at the street end where soil washed out along the curb. In both cases, a void forms under the slab, and the weight of the concrete eventually presses it down to meet the void. Finding the void shows where to drill.
Leveling lifts that slab back into place by injecting material under it. Mudjacking uses a cement slurry through holes near an inch and a half across, while polyurethane foam leveling uses holes about five-eighths of an inch and a much lighter material, which contractors say cures in minutes. For small patios between a house and a fence, the compact equipment foam crews bring and the small patch holes are often a good match. For larger areas, mudjacking can be more economical. A good crew probes the slab before lifting. They tap or drill small test holes to learn where voids are, and they plan the lift pattern to raise the slab evenly. Lifting too fast or too much in one spot can crack concrete that is already weak. Slow, staged lifting with frequent level checks avoids that, and it takes patience from both sides.
Check the cause before you lift. In Wells Branch, a common one is a downspout or an irrigation head dumping on the slab edge. Another is a void left when fill around the house settled. Lifting without fixing the cause invites a repeat. If the slab is part of the house foundation, or if cracks run into walls, a structural engineer should look first, since slab leveling is not structural repair. Costs vary by site and are not a quote. Quote details matter. A clear estimate lists the area, the method, the target lift and what happens if the slab cracks during the job. It should also explain what is included for patching holes and any warranty or guarantee the contractor offers. Never accept a promise you cannot see in writing, and compare more than one offer.
What to know in Wells Branch
Small, enclosed spaces
Patios between house and fence leave little room for equipment. Foam crews typically bring compact rigs and hoses that can run through a gate. Ask the contractor how they will access the slab, and make sure gates and side yards are clear.
Pool decks and coping
Slabs around pools should be handled by a specialist who understands the plumbing and the shell. Lifting near a pool can stress lines or coping. Check with your pool builder or an engineer before lifting any deck near a pool.
Matching the finished height
In a neighborhood of attached or closely spaced homes, a lifted patio has to meet the door threshold and neighboring slabs cleanly. A target within about a quarter inch of the neighbor slab is a reasonable ask. Mark it in advance so the crew has a goal.
Signs you may need concrete slab leveling
- A step or lip where two slabs meet
- A patio or walkway tilting toward the house
- Hollow sound when you tap the concrete
- Water puddling on a slab that used to drain
How concrete slab leveling works
There are two common materials. Mudjacking, also called slabjacking, pumps a heavy slurry of water, soil or sand and cement under the slab. Polyurethane foam leveling, sometimes called polyjacking or polylifting, injects a two-part expanding foam that grows and hardens beneath the concrete. Both can raise a slab. The difference shows up in weight, hole size, cure time and long-term behavior. We focus on foam. Contractor sources describe polyurethane foam as very light, around 2 to 4 pounds per cubic foot, so it adds little load to soft clay. Mudjacking slurry is much heavier, which can matter on weak ground. Foam holes are also smaller, about five eighths of an inch, compared with roughly an inch and five eighths for mudjacking. Those numbers come from contractor literature, so treat them as typical rather than universal.
Cure time is another practical difference. Foam generally hardens within minutes, and many sources say a slab can carry foot traffic shortly after the work. Mudjacking slurry needs longer to set before the slab sees weight. Foam is also water resistant, so it does not wash out the way a cement slurry can when downspouts or irrigation keep feeding water under a slab. That matters here because clay lots are prone to periodic soaking. Mudjacking has real strengths. It is often less expensive per slab, and it can be a good fit for large, heavy slabs where a lot of fill is needed. The trade-off is weight, bigger holes and a longer wait. Which material is the better choice depends on the slab, the soil under it and the budget. A good contractor will explain the pros and cons rather than push one answer.
What to expect on a Wells Branch 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 Wells Branch
Governance here is a little unusual. Wells Branch has long been served by a Municipal Utility District that funds parks, pools and trails, so the MUD may care about what happens in greenbelts and shared drainage areas. Depending on where your home sits, the county, the MUD and your HOA or condo association can each have a say over grading, fences and work near drainage channels. We could not verify specific permit rules for the area, so check with your MUD, the relevant county office and your HOA before regrading, building in a drainage easement or tying into a shared storm line. Texas Water Code Section 11.086 also prohibits diverting surface water in a way that damages a neighbor's property. Always call 811, since Texas law requires notice two business days before you dig, even in your own yard.
Concrete Slab Leveling questions from Wells Branch homeowners
Is foam better than mudjacking for a small patio?
Often it is a good fit, since foam is lighter, uses smaller holes and cures fast. Mudjacking can cost less and works well on larger slabs. Ask for quotes on both and ask each contractor why they favor their method for your site. Ask for the lift method, the material and the hole size in writing before you sign.
Can I level concrete myself?
Do-it-yourself kits exist, but they are limited. Lifting slabs needs control, enough material to fill voids and skill to avoid cracking the concrete. For small, light slabs it may be possible. For anything bigger or attached to a building, a professional is the safer choice. If the slab is thin or already broken, foam or slurry may not help and replacement could be better.
Will leveling fix the water problem too?
It helps by restoring the slope away from the house, but it does not solve the original cause. If gutters, grading or leaking pipes sent water under the slab, fix those too. Otherwise, the slab may drop again and you will pay for the lift twice. Plan to keep water off the slab edges for the rest of its life.
Do I need to call 811 first?
Yes, Texas requires notice to Texas811 at least two business days before digging, not counting weekends and holidays. Drilling a slab counts, because buried lines can run under patios and walks. The contractor normally makes the call, and you can ask for the ticket number. Keep the ticket number and the 811 locate flags in place until the work is finished and the holes are patched.
What is the difference between foam leveling and mudjacking?
Mudjacking pumps a heavy cement and soil slurry under the slab through larger holes, and it needs longer to set. Foam leveling injects a lightweight expanding polyurethane through smaller holes and cures in minutes. Foam resists washout but usually costs more. Both work only on slabs that are not attached to a house foundation. Always ask which material a quote uses, the hole size, and how long you must wait before using the slab.
Can you level the slab under my house?
No. Lifting a house slab and repairing foundations with piers is structural foundation repair, and it is outside our scope. A structural engineer or a foundation repair company should evaluate any movement in your home. We level exterior concrete such as patios, walks, pool decks and driveways. If you are unsure whether a slab is connected to the house, ask an engineer, because that decides what can be lifted.
