Foundation Drainage in Garland, TX
Free inspection. Fix the cause, not just the symptom.
If water pools beside your house after a storm, or one side of the yard always stays soggy, that's worth paying attention to. Piers hold a house up. Drainage deals with what pushed it around in the first place. Foundation drainage work moves water away from the house and keeps the moisture in the surrounding clay as even as possible, so the ground stops swelling on one side while it shrinks on the other.

On Garland's soil, this isn't a minor add-on. The USDA soil survey finds Houston Black clay under about 32% of the city and Ferris under another 16%. Both measure 17 on linear extensibility, the scale for how much a soil changes size with moisture. Anything over 9 is very high. Water is what moves that ground, so water is what you can control.
Water Is the Cause. Piers Are the Repair.
Clay doesn't move on its own. It moves because its water content changes.
A slab settles when the soil at the edge dries out and shrinks away, leaving the edge unsupported. It heaves when that same soil soaks up water and swells. Both come back to moisture, and moisture can mostly be managed.
That's why a repair plan that puts in piers and ignores the drainage only does half the job. The piers steady what has already moved. Without fixing the water, the next dry August starts the process over on whatever wasn't piered.
What Foundation Drainage Work Involves
Grading. The ground should fall away from the house, not toward it. Flower beds, added topsoil and years of mulch often reverse the slope without anyone noticing.
Downspout extensions. Roof water dumped at the foundation is the most common problem on this list, and the easiest to fix. Downspouts should empty at least three feet from the house, and further is better.
French drains. A gravel-filled trench with perforated pipe that collects water and carries it away. They're useful where the yard can't be regraded enough, or where one side of the house stays wet.
Root barriers. A barrier set in the ground between a large tree and the foundation, which stops roots pulling moisture from right under the slab edge. Trees within about 20 feet of the house are the ones to think about.
Soaker systems. These deal with the opposite problem. In a long dry spell, even watering around the whole house keeps the clay from shrinking unevenly. "Even" is the word that matters.
Signs Water Is Your Problem
- Water standing beside the foundation for hours after rain
- A downspout emptying straight onto the ground next to the slab
- Ground sloping back toward the house
- One side of the house always damper than the others
- Cracks that get worse in late summer and ease after a wet spell
- A large tree close to the corner that's dropping
That seasonal pattern is a strong clue. Movement that follows the weather is driven by moisture, and that kind of movement responds to drainage work.
The Leak That's Easy to Miss
Not all water comes from the sky.
A cracked sewer line or a leaking supply line under the slab soaks one patch of clay all year, whatever the rainfall. That patch swells and stays swollen while the rest of the soil follows the seasons.
This one gets missed often, and it matters, because no amount of pier work fixes a plumbing leak. A house can be piered and leveled and still move again, because the leak is still running underneath it.
It's worth suspecting a leak when:
- The water bill has climbed with no change in use
- One area of floor is warm or damp for no clear reason
- The movement is close to a bathroom or the kitchen
- Nothing about the drainage outside explains what you're seeing
A foundation inspection looks for these signs. Confirming a leak takes a plumbing test, which is separate work.
What Drainage Work Costs in Garland
The cost depends on:
- How much of the house's edge needs attention
- Whether the fix is grading and downspouts or a full French drain
- How long the trench is, and where the water can legally drain to
- Whether root barriers are part of the job
- How easily equipment can get around the house
Drainage work generally costs less than pier work. Done before serious settling starts, it's some of the best money you can spend on a Garland house.
Questions About Foundation Drainage
Will drainage work alone fix my foundation?
If the house has already settled, no. Piers correct settling that has already happened, and drainage stops it coming back. Caught early, though, drainage alone can mean you never need pier work at all.
Should I water my foundation in summer?
On this soil, yes, and evenly all the way around. Uneven watering causes the same problem as no watering, because one side swells while the other keeps shrinking.
How far should downspouts discharge?
At least three feet from the foundation. That's the figure in the City of Richardson's homeowner guidance, and further is better if your yard allows it.
Do trees really matter?
A mature tree moves a lot of water. Anything within roughly 20 feet of the foundation is worth watching, especially through a dry summer. Taking the tree out isn't always the answer, since removing a large tree can change soil moisture sharply on its own. A root barrier is often the better route.
Do I need a permit for drainage work?
Usually not, since it's typically not structural work. Garland's foundation repair permit applies once repair work is worth $2,000 or more. Building Inspection at 972-205-2300 can confirm what your job needs.
