At Anchored Walls, we’ve been helping Missouri homeowners protect their homes since 1978. Our services cover everything from structural foundation repair to complete basement waterproofing, crawl space solutions, egress window installation, and concrete leveling.
A dense clay layer called a claypan sits close to the surface across Adair County, and it doesn't drain the way looser soil does. Water perches on top of it each spring, building up around a home's foundation and pushing against basement walls from outside.
Anchored Walls has repaired foundations and waterproofed basements across Missouri since 1978, using systems built for the way this soil behaves. Every project starts with a free, in-person inspection and a written repair plan, so you know what's happening and what it costs before any work begins. Most repairs carry our Life of the Structure Warranty, backed by a money-back guarantee.
The claypan layer under Adair County holds water close to the surface each spring, and that saturated soil presses against basement walls from outside. As the ground dries out later in the season, that same soil can pull away from the foundation, leaving gaps beneath footings that were fully supported months earlier. This back-and-forth between saturated and dry soil puts uneven pressure on a foundation year after year, showing up as cracks, settlement, and shifting walls.
Water intrusion follows the same pattern. Homes without a drainage system built for a high water table can see moisture seep through basement walls and floors during wet months, leading to mold, musty smells, and wood rot over time.
Outdoor concrete faces the same soil movement. Sidewalks, patios, and driveways sink or crack as the claypan soil beneath them saturates and dries unevenly. These surface problems create tripping hazards and can direct water toward the foundation.
If you've noticed a crack in your basement wall, it helps to know exactly what you're looking at and what it means for your home. Each of these problems has its own specific characteristics, distinct from a vague sense that something in the house "feels off." Recognizing the sign in front of you is enough to know it's time to call for an inspection.
A crack in a foundation or basement wall can run vertically, horizontally, or in a diagonal stair-step pattern along the mortar joints of a block wall. Vertical cracks tend to run straight up and down and are usually narrow, while horizontal cracks run the width of the wall. A stair-step crack follows the joints between blocks rather than cutting straight through them. Running a hand along the wall can reveal a crack's edge before it's clearly visible in the light.
A bowing wall curves inward instead of sitting flat against the floor and ceiling framing around it. Standing at one end of a basement wall and sighting along its length toward the other end can reveal a curve that's hard to see head-on. A horizontal crack can appear at the point where the bow is most pronounced. In more advanced cases, the top or bottom of the wall may shift visibly out of alignment with the rest of the foundation.
Foundation settlement can leave a visible gap between an exterior wall and the ground next to it. Windows and doors set in a settling section of the house may no longer sit square in their frames. Interior floors near the affected area can develop a noticeable slope, easy to test by setting a ball down and watching which way it rolls. Exterior brick or siding can show stepped cracking that follows the same pattern as the settlement below it.
Standing water collects near a wall or in a low corner of a basement after rain, where the floor sits lowest. It can appear as a thin sheen across the concrete or as a visible puddle that takes hours to evaporate. A water stain or tide line on the wall just above the floor can mark how high standing water has reached in the past. A floor drain that backs up during heavy rain is another version of the same problem.
Basement mold appears as dark spots or patches on drywall, wood framing, or the foundation wall itself. A musty smell can be present even before the mold itself is visible. It can range from small isolated spots to larger patches spreading across a wider section of wall or ceiling. Testing a spot with a drop of bleach is one way to tell mold from ordinary dirt, since mold lightens in color within a couple of minutes and dirt doesn't.
A musty odor can be present in a basement even when no water or mold is visible anywhere in the room. The smell can come from moisture trapped in wood, drywall, or insulation rather than from standing water itself. It can be stronger in one corner of the basement than another, pointing to where moisture is concentrated. The odor can also travel through floor vents and stairwells into the rooms above.
Efflorescence is a white, chalky mineral deposit that forms on a basement wall as water evaporates and leaves behind salts it carried through the concrete. It can appear as a light dusting or as a thicker, crusty buildup, depending on how much water has passed through. A water stain is a separate but related sign, showing up as a darker discoloration that outlines the path water took down the wall. Both can appear on a wall that looks completely dry at the time it's inspected.
A concrete tripping hazard forms where one slab has sunk or shifted relative to the surface next to it, creating a visible ledge. It shows up where a driveway meets a garage floor, where one sidewalk section meets the next, or where a patio meets a home's foundation. Even a height difference of less than an inch is enough to catch a toe or a shoe. Cracking can accompany the height difference where the two slabs have pulled apart.
Frost heave happens when moisture in the soil freezes and expands, pushing up on whatever sits above it, including a concrete slab or section of foundation. An affected slab can rise noticeably during the coldest months and then settle back down, sometimes unevenly, once the ground thaws. Cracking can appear where one section of concrete has heaved higher than the section next to it. A door or gate that swings freely in summer but drags or won't close in winter can be responding to the same seasonal movement.
For more than four decades, Anchored Walls has repaired foundations, waterproofed basements, and leveled concrete for homeowners across Missouri, using systems built to solve the problem for good. Every project starts with a written plan based on what an inspection finds at your home.
For a foundation that's settled or a wall that's begun to bow, wall anchors reach past the foundation into stable soil and can be tightened over time to help straighten a wall that's already moved. Steel piers driven or screwed down to load-bearing soil transfer a home's weight off ground that's no longer supporting it, and can help lift a settled section back toward level. Each system is installed based on what an inspection finds at your specific home.
Interior drain tile installed along the footing catches water before it can push through a basement wall, and a sump pump moves that water out and away from the house. For a wall that's already cracked, direct crack repair seals the opening with material built to flex with the foundation as it moves through the seasons. A vapor barrier or dehumidifier can address the humidity left in the basement air once the water itself is under control.
Crawl space stabilizers support a sagging floor from below, lifting and holding it in place. Crawl space encapsulation seals the space with a heavy-duty vapor barrier, closing off ground moisture and outside humidity. A dehumidifier can then manage whatever humidity remains trapped inside the sealed space.
Egress windows bring natural light and a code-compliant emergency exit to a basement bedroom or living space. Each window is sized and installed to meet local building code requirements for basement bedrooms.
Polyurethane foam injected beneath a sunken slab expands to fill the void left by settled soil, lifting the concrete back to level. The process uses a small injection hole and leaves the surrounding yard undisturbed. Driveway lifting uses the same method to raise a sunken driveway.
Foundation and waterproofing work happens below ground, where it's hard to check on the quality of a repair once everything is filled back in. Anchored Walls has repaired foundations and waterproofed basements across Missouri since 1978, serving more than 1 million homeowners along the way. Most repairs carry a Life of the Structure Warranty, and every project is backed by a money-back guarantee if you're not satisfied with the result.
