If you've lived in the metroplex through a spring storm season, you know the pattern: it rains hard for an hour, and three days later there's still a soft, soggy patch in the back yard. That's not bad luck. That's blackland clay doing exactly what clay does — holding water instead of letting it pass through.
The problem gets worse when the lot was graded flat. A lot of DFW subdivisions were built on pads scraped level for construction, with no meaningful slope built back in. Water that lands on the lawn has nowhere to go, so it sits, suffocates the grass roots, and in the worst cases works its way toward the foundation.
Standing water causes three expensive problems. It kills turf — grass roots need oxygen, and saturated soil has none, which is why those patches go yellow and then bare. It breeds mosquitoes. And over years of wet-dry cycling, clay swells and shrinks against your slab, which is the mechanism behind most North Texas foundation movement.
A French drain is the standard fix, and it's simple in concept: a trench, a bed of gravel, a perforated pipe wrapped in fabric, and a slope that carries water to a discharge point away from the house. What separates a drain that works for twenty years from one that clogs in two is the details — correct fall along the whole run, the right fabric so silt doesn't pack the gravel, and a real outlet rather than a pipe that just dead-ends in the yard.
French drains often aren't the whole answer on their own. Catch basins collect water where it pools at the surface. Downspout extensions get roof runoff away from the slab instead of dumping it at the corner of the house. And sometimes the correct fix is regrading — reshaping the soil so gravity does the work before any pipe is involved.
Here's the order that saves money: fix drainage before you install anything else. New sod, fresh beds, and a paver patio installed over a drainage problem will all fail on the same schedule the last landscape did.
