DFW drainage and clay soil
North Texas clay soil expands and shrinks with moisture. Water sitting beside the home can increase foundation stress, damage landscaping, and create muddy side yards. A French drain can help when it is designed with the right slope and discharge point.
Signs you may need drainage help
- Water pools near the foundation after rain.
- Side yard stays muddy for days.
- Water enters the garage, patio, or crawlspace.
- Landscape beds wash out.
- Soil is pulling away or swelling near the home.
- Downspouts dump water in the wrong place.
French drain vs grading
A French drain is not always the only answer. Sometimes grading, downspout extensions, gutters, catch basins, or surface drains are part of the solution. A good quote should explain where the water will go after the drain collects it.
