Foundation Drainage Correction San Antonio
French drains, surface drains, gutters, and regrading to protect your foundation.
Fix the Water, Protect the Foundation
If you’re looking for foundation drainage correction in San Antonio, you might have noticed water pooling by the house after a storm, a soggy corner of the yard that never dries, or a downspout that’s been dumping water in the same spot for years.
That water matters more than most people think. San Antonio clay swells when it gets wet and shrinks when it dries. When one side of your house gets soaked over and over while the other side stays dry, the foundation moves unevenly. That’s how a lot of leveling jobs start.
It’s also why leveling a house without fixing the drainage is like mopping the floor with the sink still running.

Signs You Have a Drainage Problem
Standing water near the foundation for more than a day after rain. Soil that’s washed away from the slab edge. Downspouts that end right at the house. A yard that slopes toward the house instead of away from it.
Inside, you may notice musty smells, a damp crawl space, or cracks that seem to get worse after a wet spell. Those are all signs water is getting where it shouldn’t.
Drainage Solutions for San Antonio Homes
The right fix depends on where the water comes from and where it can go. Most homes need one or two of these.
French Drains
A French drain is a gravel-filled trench with a perforated pipe that collects water underground and carries it away from the house. It’s a good choice for yards where water soaks in near the foundation.
Surface Drains and Catch Basins
Surface drains catch water that pools on top of the ground, like low spots or the bottom of a slope, and pipe it to the street or a safer part of the yard.
Gutters and Downspout Extensions
A roof sheds a lot of water in a San Antonio downpour. Adding gutters and running downspouts several feet away from the foundation, above or below ground, is one of the cheapest ways to protect it.
Regrading
Regrading reshapes the soil so the ground slopes away from the house. It’s often paired with other drainage fixes, especially on older lots where the yard has settled over time.

Foundation Drainage FAQs
Should I fix drainage before or after leveling?
Usually as part of the same project, or right after. The leveling crew can make sure new drains don’t interfere with piers, and the house stays level longer once water is under control.
Should I water my foundation in summer?
Many San Antonio homeowners use a soaker hose a couple of feet from the slab during long dry spells to keep the soil moisture more even. Ask your inspector what makes sense for your house.
How long does a French drain last?
A well-built French drain with fabric-wrapped pipe and clean gravel can work for decades. Roots and silt are the main things that clog them.
