Standing water after every storm? Your yard isn't the problem. The clay is.
Georgia red clay absorbs almost nothing — so when a Cobb County thunderstorm dumps an inch of rain in twenty minutes, that water sits, sheets toward your foundation, or turns the backyard into a swamp for days. We design and install drainage systems built specifically for clay soil and Smyrna's rolling lots.

Three things working against your lot
Red clay that won't percolate
The Piedmont clay under Smyrna absorbs water at a fraction of the rate of loam or sand. Rain that would vanish into the ground elsewhere just sits here — which is why "wait for it to dry out" takes days, not hours.
Rolling terrain and uphill neighbors
Almost no lot in Smyrna is truly flat. Whether you're off Concord Road, near King Springs, or in a townhome community along the East-West Connector, odds are your yard receives runoff from higher ground before it ever deals with its own.
30- to 40-year-old grading
Much of Smyrna was built in the 80s and early 90s. Grading that sloped away from foundations in 1988 has settled, landscaping has changed the flow paths, and builder-grade splash blocks were never meant to handle Georgia's 50+ inches of annual rain.
Any one of these is manageable. Most Smyrna drainage problems are all three at once — which is why the fix starts with mapping how water actually moves across your specific lot.
Sound familiar?
- Water stands in the yard for 2+ days after a thunderstorm
- Mulch or soil washes out of beds and down the driveway
- A soggy stripe runs along the fence line or property edge
- Water pools against the foundation or back patio
- Crawl space smells musty after heavy rain
- Grass won't grow in the low spot — just moss and mud
- Downspouts dump roof water right beside the house
Drainage systems, matched to how your water behaves
Water that seeps needs a different fix than water that sheets or pools. We quote what the water requires — sometimes that's a full French drain system, sometimes it's a $1,500 downspout-and-catch-basin fix that solves the same problem.
French drain installation
Perforated pipe in washed gravel, fully wrapped in non-woven filter fabric so clay fines can't clog it, sloped to a legal discharge point. The core fix for seeping, saturated ground.
Catch basins & channel drains
Grated basins in low spots and channel drains across driveways and patios capture pooling water before it stands — piped underground to the same discharge network.
Downspout burial & tie-ins
A typical Smyrna roof sheds hundreds of gallons per storm right at the foundation. We bury downspout lines and carry that water to daylight or a pop-up emitter away from the house.
Regrading & swales
When water flows toward the house, pipe alone won't fix it. We re-establish positive grade away from the foundation and shape shallow swales that move sheet flow where it belongs.
Dry creek beds & erosion control
On sloped lots losing soil every storm, a stone-lined dry creek bed slows and channels runoff — a fix that controls erosion and looks intentional instead of industrial.
Crawl space & sump discharge
We route sump pump and crawl space drainage lines to proper exterior discharge, so the water your waterproofing system collects doesn't just soak back in beside the footing.
From soggy yard to dry ground
Walk the water
We assess the lot — ideally after rain — and map where water enters, where it pools, and where it can legally exit. You get straight answers on-site.
Design & written quote
A system designed for your lot's slope and soil: drain runs, basin placement, discharge point, and an itemized fixed price. No mystery line items.
Install & document
Trenching, fabric, gravel, pipe, and slope checks — with photos of the open trench before backfill so you can see exactly what's in the ground.
Restore & verify
Sod and landscape put back, discharge tested with a hose, and a walkthrough after the next real storm if you want one. Then the yard just… drains.
What yard drainage costs in Smyrna
Drainage quotes shouldn't be a mystery. Typical ranges for Smyrna-area projects:
| Project | Typical Range | Notes |
|---|---|---|
| French drain (installed) | $30 – $60 / linear ft | Depth, access, and discharge design drive the range |
| Downspout burial (per line) | $400 – $900 | To daylight or pop-up emitter |
| Catch basin + piping | $800 – $2,000 | Per basin, tied into discharge line |
| Typical complete system | $2,800 – $9,500 | Most Smyrna projects land here |
| Regrading / swale work | Per quote | Depends on area and soil moved |
| Drainage assessment | Free | On-site, with written recommendations |
Every quote is written, itemized, and fixed before work begins. If a smaller fix will solve your problem — burying two downspouts instead of trenching the whole yard — that's what we'll quote.
Drainage questions from Smyrna homeowners
Do French drains actually work in Georgia red clay?
Yes — but only if they're built for clay. Red clay barely absorbs water, so the system can't rely on soil percolation; it has to intercept water and carry it somewhere: a daylight outlet, a pop-up emitter near the curb, or a dry well on flat lots. We size the pipe, gravel envelope, and slope for clay conditions and always wrap the gravel in non-woven filter fabric so clay fines can't clog the pipe — the number-one failure in cheap installs.
Where does the collected water actually go?
Every system needs a legal, downhill discharge point — a daylight outlet at lower elevation, a pop-up emitter where water can reach the street gutter, or a dry well. What you can't do is concentrate runoff onto a neighbor's lot; Georgia law can make you liable for that. Designing a compliant outlet is part of every assessment.
How much does a French drain cost here?
Most Smyrna installations run $30–$60 per linear foot, with complete projects typically landing between $2,800 and $9,500. A 60-foot interceptor drain with a pop-up emitter sits near the low end; systems combining French drains with catch basins, buried downspouts, and regrading trend higher. Quotes are free, written, and itemized.
Why does my yard flood when my neighbor's doesn't?
Smyrna sits on rolling Piedmont terrain, so most lots receive uphill runoff from somewhere. Add compacted clay, decades-old grading that has settled since the neighborhood was built, and downspouts dumping roof water at the foundation — one lot can end up collecting water from several. An assessment maps exactly where your water comes from and where it can go.
Do I need a French drain, a catch basin, or regrading?
It depends on how the water behaves. Seeping, saturated soil calls for a French drain. Surface pooling in a low spot calls for a catch basin or channel drain. Water sheeting toward the house calls for regrading or a swale. Many Smyrna yards need a combination — and sometimes burying downspouts plus one catch basin solves what looked like a French-drain problem at half the cost. We quote what the water requires.
How long will the system last?
A properly built system — fabric-wrapped gravel, adequate slope, cleanout access — should perform 25–40 years in our soil. Early failures almost always trace to missing filter fabric (clay silts in and clogs the pipe) or insufficient fall. That's why we photograph every open trench before backfill: you see exactly what went in the ground.
I'm in a townhome with an HOA. Can you still help?
Usually, yes. Smyrna has a large share of HOA-governed townhome communities, and drainage responsibility often splits between the owner and the association. We'll identify whether the problem originates on your lot or common ground, document it with photos, and provide the written assessment HOAs typically require before approving exterior work.
