Chattanooga Foundation Co. connects you with a local specialist for the full failure chain hillside water causes: slope runoff (drainage from under $500), settlement (piers from $1,200 each), uphill wall movement (from $2,500), cracks (from $400), and failing retaining walls (from $1,500). Each preceded by a measured evaluation.
Foundation Piering & Underpinning
Steel piers to rock or stable bearing where residual soil over bedrock let a footing down.
Slope Drainage Correction
Intercepting hillside runoff above the house: the cheapest structural work in this market.
Bowing Wall Repair
Carbon fiber, braces, and anchors for uphill walls carrying slope and water pressure.
Foundation Crack Repair
Injection, sealing, and reinforcement for cracks that leak, widen, or both.
Retaining Wall Repair
Drainage, anchors, and rebuilds for the walls holding your hillside in place.
Foundation Settlement Repair
On slopes, settlement and slide wear the same clothes: measured diagnosis first.
Helical Piers vs Push Piers
Hillside cuts, valley karst, and two proofs of bearing: matched to the house.
Crawl Space Waterproofing
Hillside crawl spaces catch the hill’s water: drainage, barriers, and dry wood.
Exterior vs Interior Waterproofing
The uphill wall takes the hill’s runoff, where the system belongs on a slope.
Insurance & Foundation Repair
Tennessee’s exclusions, the sinkhole election, and the slope-water causation fight.
Structural Engineer or Contractor?
Hillside cuts and karst valleys give the stamp real work, and the survey answers the rest.

Why the services come as a set
Water on a slope doesn't respect a product line. The same runoff that saturates the backfill behind your uphill wall washes fines out from under the footing, finds every crack in the foundation, and overloads the retaining wall holding your driveway up. Companies organized around one product sell that product. A good specialist is organized around the water, so an evaluation reads the whole chain and the scope includes only the links your house actually needs.
Which repair fixes which failure
| What you see | The mechanism | The fix | Typical range | Time |
|---|---|---|---|---|
| Water crossing the lot, wet crawl, soggy uphill side | Slope runoff concentrating at the foundation | Interception above the house | Under $500–$8,000 | 1–2 days |
| Stair-step cracks, dropped corners, sloping floors | Footing settling where soil over rock is deeper or washed | Piers to refusal | $4,000–$15,000 | 2 days–1 week |
| Uphill wall cracked horizontally or pushed inward | Saturated hillside soil loading a cut-slope wall | Carbon fiber, braces, or anchors | $2,500–$10,000 | 1–3 days |
| Cracks leaking, or reacting to heavy rain | Water finding a path through the foundation | Injection and reinforcement | $400–$1,500 | Hours |
| Retaining wall leaning, bulging, or shedding block | Saturated backfill with nowhere to drain | Drainage, anchors, or rebuild | $1,500–$12,000 | 1 day–1 week |
Two or more symptoms nearly always share one cause. One evaluation, one scope, one mobilization. That's the cost control this terrain allows.
Sequence is the service, and here it starts uphill
Anyone can bolt a brace to a wall. The skill in this market is ordering the work so it stays fixed: intercept the water above the house first, because it's the cheapest line and it removes the cause; correct grading and hardscape that concentrate flow; then structural restraint or piering, now working against a much smaller load; then cosmetic repair last, once movement is provably over. Ask for a scope written in that order with an itemized price per line, and for lines the measurements don't justify to be left off.
Service questions
Which service does my house actually need?
The evaluation answers that in about an hour, and on a hillside it starts uphill. Water crossing the lot points to drainage; stair-step cracks with sloping floors point to piering; a cracked or pushed-in uphill wall points to restraint; a leaning wall near the house points to retaining work. Most hillside houses need two of these, not five.
Is there a charge for evaluations?
Many local specialists don't charge for the first visit, but it depends on the company. Ask when the specialist calls, before they come out. Ask for photos, crack measurements, laser floor elevations, wall plumb readings, and a walk of the water path above the house, including on visits that end with 'build a swale and extend the downspouts' rather than an invoice.
Can one crew handle the water and the structure together?
That's the point of the stack, and here it's the difference between a repair that holds and one that doesn't. Drainage, piering, wall restraint, crack work, and retaining walls are one slope-water problem wearing five costumes. Scoping them together in the right order is how you avoid installing steel into a problem that's still running.
