Houston gets heavy rain in short bursts, and water that lands on your roof has to go somewhere. If it pools against the slab, it feeds foundation movement, mold and erosion. Managing water starts at the roof and ends at the street.

What we do

  • Gutter and downspout sizing with underground tie-ins
  • French drains and surface channel drains
  • Regrading yards so water flows away from the foundation
  • Architectural retaining walls in stone, block and timber
  • Erosion control on sloped and creek-side lots
  • Patio and walkway drainage

Why it matters

Sloped lots around Kingwood and Lake Houston are especially prone to erosion. A well-built retaining wall with proper drainage behind it holds the hill and adds usable yard space.

Frequently asked questions

Do retaining walls need drainage?

Yes. Without gravel backfill and a drain behind it, water pressure builds up and can push the wall over time.
