Yard Drainage Problems in Red Clay Soil

Why Georgia red clay holds water, the warning signs to watch for and practical fixes from simple to serious.

If you live in west Georgia, you know red clay. It holds onto water, sticks to everything and bakes hard in summer. Clay isn't all bad. It holds nutrients well. But it drains slowly, and heavy summer storms can leave puddles that hang around for days. Here's how to read the signs of a yard drainage problem and what you can do about it.

Why clay drains poorly

Clay soil is made of tiny, flat particles that pack together tightly. There's not much space between them for water to move through. When clay gets walked on, driven on or worked while wet, it packs even tighter. Add a low spot or a yard that slopes toward the house, and water has nowhere to go.

Signs of a drainage problem

• Puddles that stay a day or more after rain
• Soggy, spongy spots in the lawn
• Moss, algae or bare patches where grass won't grow
• Soil washing out and leaving gullies on slopes
• Water stains or dampness along the foundation
• A musty smell or standing water in the crawl space
• Mulch and pine straw washing out of beds
• Mosquitoes breeding in standing water

Start at the house

Most serious drainage trouble starts with water that comes off the roof. A roof sheds a lot of water in a hard rain, and it all lands somewhere.

Gutters and downspouts

• Keep gutters clean. Pine needles, pollen and leaves clog them fast. Overflowing gutters dump water right at the foundation.
• Extend downspouts. Water should exit well away from the house. Splash blocks or extensions that carry water several feet out help a lot.
• Watch where it goes. Make sure the outlet points downhill and doesn't just flow back toward the house or onto a neighbor's property.

Grading near the foundation

The ground right around your house should slope away from it. A common guideline is about 6 inches of drop over the first 10 feet. Over the years, soil settles and mulch builds up, and the slope can flatten or even tip back toward the house.

Pulling mulch and soil back so siding and wood trim aren't buried also helps prevent rot and termite problems. Our guide on preventing porch wood rot covers that in more detail.

Fixes for the yard

Core aeration

Core aerating pulls small plugs of soil out of the lawn. That loosens compacted clay and lets water and air move in. It works best on actively growing grass, so late spring to early summer for warm-season lawns and fall for tall fescue.

Add organic matter

Topdressing with a thin layer of compost after aerating, year after year, slowly improves clay. In beds, work compost into the soil before planting. Avoid adding just sand to clay. In small amounts it can make clay harder.

Fill low spots

Shallow dips can be leveled out with a topsoil and compost mix, added a little at a time so grass can grow up through it.

Plant for wet spots

Some spots will always be damp. Instead of fighting it, plant something that likes wet feet, or turn it into a rain garden that holds water briefly and lets it soak in.

Dry creek beds and swales

A shallow, gravel-lined channel can carry water across a yard to a better spot. A swale, a gentle grassy ditch, does the same thing. These work best when there's somewhere lower for the water to go.

When to call a drainage pro

Some problems are beyond simple fixes. Call a landscape or drainage contractor if:

• Water is getting into your crawl space or basement
• The yard needs regrading over a large area
• You need a French drain or other buried drainage system
• Erosion is undercutting a slope, driveway or retaining wall
• Water from a neighbor's property or the street is part of the problem

Foundation cracks or a damp crawl space can also call for a foundation or waterproofing specialist. Getting the right expert early is cheaper than fixing water damage later.

Before storm season

Heavy summer storms test every drainage weak spot. Before they hit, clean gutters, check downspouts and clear debris from ditches and drains. Our storm prep and cleanup guide has a full checklist.
