Sunken concrete in Mission is almost always a clay soil problem. We lift slabs back to level, fill the voids underneath, and get your driveway, patio, or entry safe to walk on - usually in a single day.
Foundation raising in Mission is the process of pushing a sunken concrete slab back up to level by drilling small holes through the slab and pumping material underneath to fill voids and lift the concrete - most residential jobs are completed in a single day with surfaces ready to walk on the same afternoon.
In Mission, slabs sink because the clay-heavy soil underneath them shrinks during our long dry summers and swells again when the rains return - a cycle that repeats every year. Once voids form under a slab, the concrete has nothing to rest on and starts to drop. If you have a sunken section that still looks structurally sound, raising it is almost always faster and less expensive than a full replacement. Homeowners who need the complete picture from ground preparation through the finished pour can also explore our slab foundation building service for new construction or full replacement situations.
Getting a straight answer about whether your slab needs lifting or something else is the first step. We walk the area with you, explain what we see, and give you a written estimate before any decision needs to be made.
If a door that used to swing freely now drags on the floor, or a window that opened easily now jams, the frame around it may have shifted because the slab beneath it moved. In Mission, this symptom often shows up after a long dry summer when the clay soil has pulled away from the foundation. It does not always mean a serious problem, but it is worth having someone take a look before it gets worse.
Small hairline cracks in tile or drywall near the floor are common in older Mission homes. But cracks wider than a credit card's thickness, or cracks that are visibly growing over several months, point to the slab moving unevenly underneath. Diagonal cracks at the corners of doorways are one of the clearest signals of foundation movement in South Texas homes.
If you can see a clear lip where one driveway, patio, or sidewalk panel has sunk below the one next to it, the soil underneath has shifted or washed away. This is one of the most straightforward situations for foundation raising - the slab is intact, it has just dropped, and lifting it back is usually a clean fix with results you can see the same day.
Mission gets intense but infrequent rainfall, and water that pools against the foundation after a storm can wash away the soil underneath the slab. If standing water near your home's perimeter takes more than a few hours to drain, that drainage pattern is working against your foundation - and lifting alone will not help unless the water problem is also addressed.
We offer two main lifting approaches depending on what your slab needs. The older method - mudjacking - pumps a cement-and-soil slurry through holes drilled in the slab to fill voids and push the concrete back up. It works well for larger areas and heavier slabs. The newer approach uses an expanding polyurethane foam that goes in through smaller holes and cures faster, making it a good fit for tighter spaces and situations where minimal surface disruption matters. For homeowners whose sunken concrete is connected to a broader structural concern, our concrete cutting service handles the removal of sections that cannot be lifted and need to be replaced cleanly.
Every job starts with an on-site evaluation to confirm the slab is a good candidate for lifting. We measure how far it has dropped, probe for void depth, and tell you honestly whether raising makes sense or whether a different approach would serve you better. All estimates are written, all hole patches are completed before we leave, and we walk you through the finished work before we go.
Suits homeowners with larger sunken areas - driveways, garage aprons, and wide patios - where the heavier slurry material fills voids effectively and the slab needs maximum support underneath.
Suits homeowners with smaller sunken sections, tight access areas, or situations where a faster cure time and smaller drill holes are a priority, such as entry walks or interior slabs.
Suits homeowners with a sunken sidewalk panel, front entry step, or patio edge that has created a lip someone could trip on - lifted back to level in a few hours with the surface ready to use the same day.
Suits homeowners preparing to list a property where an inspector or buyer is likely to flag a sunken slab - a documented repair with written records answers questions before they become deal-breakers.
Mission sits on clay-heavy soil that is common throughout Hidalgo County. That soil swells when it absorbs water and shrinks when it dries out - and with summer temperatures regularly hitting 100 degrees or higher for weeks at a time, the soil pulls away from the underside of your slab every single year. Multi-week dry spells from June through September are routine, and the moment that dry soil separates from the concrete above it, a void forms. Homes built in Mission's established neighborhoods from the 1970s through the 1990s have been through decades of these cycles, which is why sunken slabs are a common sight in areas like those near downtown Mission and the older residential streets close to Conway Avenue.
The flat terrain and irrigation canal network around Mission also mean soil moisture swings faster here than in many other parts of Texas. When heavy rains follow a dry stretch, the ground can go from parched to saturated in hours, and that rapid change puts stress on every concrete slab sitting on top of it. Homeowners across the Rio Grande Valley - including those in McAllen - deal with the same conditions, and the right response is not just lifting the slab but also making sure water drains away from the foundation rather than pooling against it.
When you call, we ask a few basic questions - where the problem is, how long you have noticed it, and whether there are cracks nearby. We reply to all messages within one business day and can usually schedule a site visit within a few days of your first contact.
We walk the affected area with you, check the slab for cracks, and measure how far the surface has dropped. We use a level to map low spots and probe the soil around the perimeter. This visit takes thirty to sixty minutes, and we explain in plain language what we find before we leave.
After the visit you receive a written estimate that covers which method will be used, how many holes will be drilled, and the total cost. If a City of Mission permit is required, the estimate notes who handles it. We never start work without your written approval.
On work day, the crew drills a pattern of small holes, pumps material underneath in a controlled sequence until the slab is level, then patches all holes with concrete before leaving. Most residential jobs wrap up in a single day, and we walk you through the finished area so you can see the results before we go.

(956) 833-0052We work on Hidalgo County clay soil every week. We know how the shrink-swell cycle damages slabs here, what void depths typically look like after a long Mission summer, and how to set realistic expectations for how long results will last. That local experience means we are not applying a generic process to a condition that has specific causes here.
Not every sunken slab is a good candidate for lifting. If your concrete is cracked in a way that suggests it has broken apart underneath, we will tell you that directly rather than taking your money for a repair that will not hold. That kind of honest evaluation is what builds long-term trust in a neighborhood where word travels fast.
We serve Mission and all 11 surrounding communities across the Valley, including McAllen, Edinburg, and Pharr. That reach means your job is not a detour for our crew - we are in these neighborhoods regularly and know the soil and drainage conditions that vary block by block.
When a City of Mission permit is required, we pull it before work begins and provide written records of everything done. For homeowners who plan to sell, that documentation matters - buyers and their inspectors look closely at foundation history in the Rio Grande Valley, and a paper trail is worth having. Texas TDLR residential construction registration is a quick check any homeowner can do to verify a contractor is operating legally in the state.
Foundation raising in Mission is not a complicated sale - either your slab is a good candidate or it is not. We would rather tell you the truth upfront than take a job that will not deliver lasting results on clay soil that never stops moving.
The Texas A&M AgriLife Extension has published guidance on managing expansive soils and foundation moisture in South Texas - a useful read if you want to understand what makes Mission soil conditions different from other parts of the state. For permit questions specific to your job, the City of Mission Building and Development Services office can answer what applies to your specific scope of work.
When a sunken or damaged slab cannot be lifted, clean cutting removes the affected section so a proper replacement pour can bond to straight, solid edges.
