Kansas City Foundation Co. runs the metro's complete structural stack: piering from $1,200/pier, wall restraint from $2,500, crack injection from $400, drainage from $2,500, slab leveling from $500 — each preceded by a free measured evaluation on either side of State Line.
Foundation Piering & Underpinning
Steel driven below the rated clay to strata that don't cycle — settlement, ended.
Bowing Basement Wall Repair
Restraint for walls losing to Group D water pressure — measured, matched, warrantied.
Foundation Crack Repair
Injection and stitching before a hundred freeze-thaw cycles do their annual mining.
Basement Waterproofing
Drainage engineered for soil that refuses to drain itself — the metro's real first repair.
Concrete Leveling
Winter-heaved, summer-slumped slabs floated back to grade in hours.
Foundation Settlement Repair
Sixty-to-eighty-percent clay takes footings down in steps — measured diagnosis, then piers.
Helical Piers vs Push Piers
Torque or refusal — the proof your house can actually deliver, on very-high shrink-swell ground.
Exterior vs Interior Waterproofing
Group D soil doesn’t drain — where the water system belongs in a KC basement.
Insurance & Foundation Repair
Missouri’s earth-movement exclusion, the frozen-pipe winters, and what to document.

Cost Guide: KC Repair Prices, Explained
Every repair priced for this metro, the cost drivers unique to rated clay, and how to referee bids.
Order of operations is the craft
Anyone can sell one of these services. The KC discipline is sequence: water exits before steel (or Group D ground reloads the problem), structure before finishes, cosmetics only after movement is instrumentally over. Scopes are written in that order, priced line by line, and stripped of any line the measurements don't justify — the fastest way to earn a metro's trust is to keep declining work it doesn't need.
Which repair fixes which failure
| What you see | The Wymore-Ladoga mechanism | The fix | Typical range | Time |
|---|---|---|---|---|
| Settlement cracks, sticking doors, sloped floors | Very-high shrink-swell clay cycling under footings | Piers below the active clay | $4,000–$15,000 | 2 days–1 week |
| Horizontal wall crack, inward bulge | Saturated clay + 100 freeze-thaw cycles pushing laterally | Carbon fiber, I-beams, or plate anchors | $2,500–$10,000 | 1–2 days |
| Cracks leaking or growing | Cycling opening paths through block and pour | Flexible-first injection | $400–$1,500 | Hours |
| Wet basement, cove-joint weeping | Group D soil holding water against the wall for days | Channel, sump, winter-safe discharge | $2,500–$8,000 | 1–3 days |
| Stepped walks, tilted aprons, sunken patios | Slabs riding the clay cycle directly | Polyurethane lifting, post-thaw | $500–$2,500 | Hours |
Multiple symptoms almost always share the one cause this county is famous for. One evaluation, one scope, one mobilization — that's the cost-control the clay allows.
Both sides of the state line, one soil complex
The metro's peculiarity is administrative, not geological: the Wymore-Ladoga clay ignores the Missouri-Kansas line, but codes and permits don't. Jackson County work and Johnson County work carry different permit paths and inspection habits for identical physics — our scopes handle the paperwork on either side, and the written scope names the jurisdiction so the engineering letter lands where the inspector expects it. What doesn't change crossing State Line Road: the 36-inch frost spec, the hundred-cycle winters, and the clay percentage doing the pushing.
Service questions
Which repair does my house actually need?
The instruments answer that better than a menu can. An hour of measurement — laser floor levels, wall deflection, crack log, water walk — typically reduces five services to one or two justified lines. Horizontal cracking calls restraint; racking plus slope calls piers; the spring damp line calls drainage; plenty of houses call for monitoring and nothing else.
Why do KC repairs so often involve two systems?
Because the failure chains here travel together: the wet season that loads a wall is the same moisture cycle that settles a footing and mines a crack. Reading the whole set — and sequencing water before steel — is what makes the fix permanent and the mobilization single.
Is the evaluation genuinely free?
Yes — measured, photographed, written, and free on both sides of the state line. When the honest verdict is 'watch it,' you get that in writing with a dated baseline to watch against.
