Drainage Correction in Houston, TX

Water that sits against the slab after rain soaks the clay on one side of the house and not the other. That uneven moisture is one of the main reasons foundations move. We fix where the water goes.

Signs you may need drainage correction

  • Water pooling next to the house after rain
  • Gutters that dump right at the slab
  • Soil sloping toward the house
  • Mud lines on the brick
  • A soggy flower bed against the foundation
  • Erosion under the slab edge
  • Water in the garage after storms
  • Cracks on the low side of the house

Good to know in Houston

Houston gets heavy downpours after long dry spells. Good drainage keeps the clay under your slab at a steady moisture level.

Watering the slab edge in a drought matters too. Deep watering beats a quick spray.

Questions about drainage correction

Can drainage alone fix my foundation?

Not if the slab has already moved a lot. It does keep small problems from getting worse.

Do I need a permit?

Most yard drainage does not, but HOA rules may apply. We check.

Will it ruin my landscaping?

We plan around beds and trees and put everything back.

How do I water my foundation in a drought?

A soaker hose about a foot from the slab, a few times a week in summer.
