Foundation Drainage in Calallen, TX
Far enough inland to be spared the worst surge, but squarely in the wind and heavy-rain field of any storm that comes ashore near Corpus Christi, and the Nueces River bottom nearby makes drainage and flood awareness part of local life.
Inland coastal plain with heavy expansive clay soils, among the most movement-prone in the Corpus Christi area. The clay swells and shrinks hard between wet and dry seasons, which drives foundation, slab, and drainage work locally.
For foundation drainage, the service area covers roughly 50 miles from central Calallen.
Common reasons to call
- Water pooling against the slab after rain
- Downspouts dumping near the foundation
- Muddy side yard or standing water by the fence
- Cracks, sticking doors, or foundation movement concern
- Need French drain, catch basin, or grading plan
- Expansive clay soil movement in Calallen or Southside
- Neighbor runoff or subdivision drainage problem
- Post-storm drainage repair before more rain
Typical work
- Drainage walk-through with slope and water-flow review
- French drain install
- Catch basin and solid-pipe discharge routing
- Downspout extensions and underground drain lines
- Swale shaping and minor grading
- Sump basin or pump coordination where gravity drainage will not work
- Foundation watering and soil-moisture plan coordination
Typical turnaround
Simple drainage corrections can be scheduled within a few business days after site review. Larger systems depend on utility locates, rain, slope, access, soil conditions, and permit needs.

Common questions
Why is water pooling by my foundation?
Usually it is slope, gutters, downspouts, compacted clay, fence-line grading, or a low side yard. The fix is to move water away from the house without sending it where it causes another problem.
Is drainage work licensed in Texas?
Texas does not have a general drainage contractor license. If the work affects structural design, public drainage, or engineered grading, a licensed engineer or local permit may be needed.
Do I need a French drain or a surface drain?
It depends on where the water is coming from. Surface water needs catch basins or grading. Groundwater and soggy soil may need a French drain. Many yards need both.
Can drainage stop foundation movement?
Good drainage helps control moisture swings, which matter in expansive clay soil. It is not a magic foundation repair, but it can reduce one of the common causes of movement.
Where does the water discharge?
That has to be planned. Water should not be dumped against a neighbor, into an easement improperly, or into a place that erodes the yard. Gravity, slope, and local rules decide the outlet.
Should gutters be part of the drainage plan?
Yes. Gutters and downspouts are often the cheapest first fix. If roof water lands next to the slab, a yard drain will be fighting the same problem over and over.
Can you work around sprinkler lines?
Yes, but mark what you know and expect surprises. 811 marks public utilities. Private sprinkler, lighting, and low-voltage lines may not be marked unless you point them out.
Coastal Bend seasons
Spring (March - May)
Heavy rain makes drainage problems obvious. Good time to document pooling before the yard dries out.
Summer (June - August)
Clay soil shrinks and cracks in heat. Foundation watering and drainage balance both matter.
Fall (September - November)
Hurricane-season rain can overwhelm low yards and side yards. Fix known pooling before named storms.
Winter (December - February)
Good time for planned drain installs, grading, and gutter tie-ins when soil is less saturated.
