Foundation Drainage Correction in New Braunfels, TX

New Braunfels gets about 36 inches of rain a year, and much of it can fall in a few heavy storms. Where that water goes after it leaves the roof decides a lot about how a foundation behaves.

01Typical drainage fixes

Regrading soil so it slopes away from the house, extending downspouts, adding French drains or surface drains, and correcting flower beds that trap water against the slab are the most common jobs. On hillside lots, a drain across the uphill side can stop runoff from soaking under the house.

02Why it matters on clay

Clay that stays wet on one side of a house and dry on the other moves unevenly. Even moisture is the goal. That is why drainage is often recommended along with house leveling or pier work, and why some crews suggest controlled watering during drought.

Water pooling under a raised floor rots wood and softens pier pads. Pair surface drainage with crawl space repair if the crawl space stays damp.

Pricing

Rock vs clay

Piers stop at shallow limestone on some west-side lots and run deeper in eastern clay.

Support count

Every pier adds materials and labor; ask for a layout drawing.

Home size and type

Two-story and pier and beam homes need different equipment.

Flood and drainage work

Low lots near the rivers may need grading or drains alongside repair.

Engineer report

Often requested for sales or insurance; adds a fee but an independent view.

Ground conditions

Rock to the west, clay to the east

LimestoneClaySimplified illustration, not a soil survey.
  1. West of I-35Hill Country edge: shallow limestone and rocky soil. Piers may stop at rock sooner.
  2. Along the escarpmentMixed ground where rock and clay meet; settlement can differ across one house.
  3. East toward the prairieDeeper expansive clay. Moisture swings drive more movement and deeper piers.

How the work usually goes

Evaluate, plan, lift, monitor

  1. 01

    Evaluate

    Elevations, crack patterns, drainage and soil type are checked to find why the house moved.

  2. 02

    Plan

    The contractor writes up pier layout, depth, drainage fixes and warranty terms.

  3. 03

    Lift

    Piers or new supports go in and the home is raised toward level as far as framing allows.

  4. 04

    Monitor

    Final readings are recorded so future movement can be compared against them.

Questions

Frequently asked questions

Can drainage alone fix my foundation?+

Sometimes it stops minor movement, but it will not lift a house that has already settled.

Should I water my foundation?+

During long droughts, steady watering of the soil near the slab can reduce shrinkage. Ask your contractor for advice specific to your lot.
