Control the water and you control the clay
On expansive clay, water is the engine behind most foundation movement. A corner that floods every storm swells; a corner shaded by a thirsty oak shrinks. Uneven moisture means uneven movement. That's why many Tulsa foundation pros pair structural repair with drainage work, and why drainage alone sometimes solves early-stage problems.
Drainage fixes that protect a foundation
- Gutters and downspout extensions that discharge at least 5 to 10 feet from the house
- Regrading so soil slopes away from the foundation (about 6 inches of fall over the first 10 feet is a common target)
- French drains or surface drains to carry water from low spots and side yards
- Root barriers between large trees and the foundation
- Fixing sprinkler heads that spray the foundation wall
Signs drainage is part of your problem
- Water standing near the foundation after rain
- Erosion or soil pulling away from the slab in summer
- Cracks concentrated on one side of the house
- A damp crawl space or musty smell
