A cracked slab does not fix itself, and waiting rarely makes the repair cheaper. If you own a home in Longview or anywhere in Gregg County, there is a good chance it sits on a concrete slab, and a decent chance that slab has shifted at least a little since the day it was poured. Here is what a slab foundation actually is, why East Texas clay gives it trouble, what the warning signs look like, and how a repair gets done, before you pick up the phone.
A slab-on-grade foundation is a single flat pour of reinforced concrete that sits directly on the ground and doubles as the home's floor. There is no crawl space underneath and no basement below it. The plumbing runs through or under the slab itself, the framing sits on top of it, and the whole house rests on that one continuous piece of concrete. It is the most common foundation type in newer Longview construction, and for good reason: it is faster to build, cheaper than a crawl space or basement, and it works well in a climate where frost heave is not the design concern it is up north.
Builders switched to slab construction across Texas starting in the mid-twentieth century because it cut costs and construction time, and East Texas builders followed the same trend. A slab needs less lumber, less labor, and less time on site than a raised foundation with piers and beams. Once concrete trucks and grading equipment became standard on job sites, slab-on-grade became the default for subdivisions built from the 1960s onward, and it has stayed the default since. Walk through most neighborhoods built in the last fifty or sixty years in Longview and you are almost certainly looking at slab construction, whether the siding is brick, vinyl, or hardie board.
The short answer: the clay soil under most Longview homes changes volume with moisture, and a slab that cannot move with it starts to crack, settle, or heave. Concrete is rigid. Clay is not. When the ground underneath a rigid slab swells in one spot and shrinks in another, the slab either cracks to relieve the stress or bends slightly out of level. Neither is good, and both get worse the longer the cycle repeats.
Clay-heavy soil, and Gregg County has plenty of it, absorbs water and expands, then dries out and contracts. A wet spring can push soil up under one corner of a slab while a dry August pulls it back down a few months later. Do that every year for a couple of decades and the slow, uneven movement adds up, even if no single season looks dramatic on its own.
Texas has had its share of hard drought years, including the severe drought of 2011 and dry stretches again in 2022 and 2023 that hit East Texas hard. During a drought, clay soil shrinks away from the edges of a foundation and pulls moisture out from under the slab faster than it can be replaced. That uneven drying is often when homeowners notice new cracks or a door that suddenly will not latch, months after the dry weather started, not during it.
A slab foundation buries the plumbing, which means a slow leak under the concrete can run for a long time before anyone notices water where it should not be, or a jump on the water bill. That extra moisture softens the soil right under the slab and can cause localized settling that has nothing to do with drought or clay swelling elsewhere in the yard. A plumber usually needs to find and fix the leak before a foundation repair will hold.
Some signs show up inside the house, some show up on the exterior brick, and some show up at the roofline. None of them proves a foundation problem on its own, but two or three together are worth a look.

There is no single correct repair method. The right one depends on how much the slab has moved, why it moved, and what access the crew has around the perimeter of the house. A reputable contractor should be able to explain which method fits your situation and why, not just default to whatever they sell the most of.
Pressed concrete pilings are cylindrical concrete sections stacked and pressed into the ground using the weight of the house itself as leverage, driven down until they reach load-bearing soil or bedrock. They have been used in Texas foundation repair for decades and cost less than steel in many cases. The tradeoff is that they rely on the soil's own resistance to stop the pressing process, which makes them less predictable in soil that varies a lot in density from one spot to the next.
Steel piers, sometimes called push piers, are hydraulically driven steel sections pushed down to refusal, meaning they stop only when they hit soil or rock dense enough to resist further pressure, regardless of depth. They tend to reach more consistent bearing capacity than pressed concrete, which is why many contractors prefer them for heavier structures or homes with more significant settling. They generally cost more than pressed concrete pilings.
Mudjacking pumps a cement-based slurry beneath a settled slab to lift it back toward level, while polyurethane foam injection does the same job with an expanding foam that cures in minutes instead of days. Both work well for a slab that has settled evenly but is not actively sinking because of a structural soil problem. Neither is the right fix for a foundation that needs piers to stop ongoing movement. Foam has become more common in recent years because it is lighter, cures faster, and requires smaller injection holes than mud.
| Method | Best Fit | Consideration |
|---|---|---|
| Pressed concrete pilings | Moderate settling, budget-conscious repairs | Relies on soil resistance, less predictable depth |
| Steel piers | Heavier loads, ongoing or more severe settling | Higher cost, more consistent bearing depth |
| Mudjacking / polyurethane foam | Even settling without active structural movement | Not a fix for a foundation that needs piering |
A repair visit starts with an inspection, moves through pier placement one location at a time, and ends with a recheck of the doors and cracks that prompted the call in the first place. None of it is mysterious, and a company that will not walk you through the steps before you sign anything is one to be skeptical of.
It depends, and any contractor who quotes a firm number over the phone before seeing your slab is guessing. The real cost drivers are how many piers the repair needs, which method fits your soil and your home's weight distribution, how deep the piers have to go to hit stable ground, and how much access the crew has around your foundation. A repair with four piers on one corner costs a fraction of a full-perimeter piering job with twenty or more. A reputable Longview foundation repair company will walk your property, measure the actual movement, and give you a written estimate at no cost before any work starts, so you are not paying just to find out what the job costs.
No. Hairline cracks under about a sixteenth of an inch are common in concrete and often relate to normal curing and shrinkage rather than structural movement. Cracks that are wider, that run diagonally from a corner, or that keep growing over a few months are the ones worth having inspected.
Most of the time, yes. Piering work happens outside and around the perimeter of the house, so the interior stays livable during the repair. Some homeowners choose to be out of the house for the loudest part of the work, particularly with young kids or pets, but it is rarely required.
A straightforward repair with a handful of piers often wraps up in a day or two. Larger jobs involving the full perimeter of the house, or ones complicated by landscaping, retaining walls, or tight access, can take longer. Your contractor should give you a time estimate as part of the written quote.
Piering stabilizes and often improves the level of the slab, which can close gaps and free up doors that were sticking because of foundation movement. Cosmetic repairs like drywall patching, repainting, and rehanging doors are usually a separate step after the foundation work is done and the house has settled into its new position.
Usually not, if the cause is soil movement, drought, or normal settling, since most policies treat that as gradual and preventable rather than a sudden covered event. Coverage is more likely if a specific covered peril, like a plumbing leak, caused the damage, but that depends entirely on your policy language. Check with your insurance agent before assuming either way.
