Drainage Correction
Half of foundation problems start with bad drainage. If you don't fix the water, the foundation will move again.
Drainage is the half of foundation work that’s invisible. You can spend $10,000 on piers, but if water keeps soaking the soil under your slab, you’ll be back in 5-10 years.
We assess and fix the surface and subsurface water that drives foundation movement in Killeen and across Bell County.
What we actually fix
Bad grade. The soil around your house should slope away at about 6 inches over the first 10 feet. Older Killeen lots often slope toward the foundation instead, sometimes from settlement and sometimes from years of landscaping additions. We regrade with new fill and reseed.
Downspouts that dump too close. Standard downspouts drop water within 2 feet of the foundation. We extend them 6-10 feet out with buried PVC, or convert to splash blocks where space allows.
French drains. Where surface grading isn’t enough (clay soil holds water rather than draining it), a French drain collects subsurface water and routes it away. It’s a perforated pipe in gravel. The perimeter type runs along the foundation. The area type collects from a low spot in the yard.
Surface drains. Catch basins in low spots, channel drains across driveways or patios. Connect to the same outlet as the French drain or to the street.
Why drainage matters more in Killeen than in dry climates
The Black Prairie clay under most Bell County homes is what’s called expansive soil. It absorbs water (swells) and loses water (shrinks) more than typical loam or sand. The bigger the moisture swing, the more the soil moves, and the more your foundation moves with it.
A house with good drainage sees relatively even soil moisture year-round. A house with bad drainage gets soaked in winter and bone-dry in summer, and the soil moves inches over a decade. Same lot, same house design. Totally different foundation outcomes.
When to schedule
Drainage work is usually done before or alongside foundation repair. Doing it after means you’ve fixed the symptom but not the cause. Call (254) 555-0123 to get the assessment. Most homes need some combination of the four fixes above, and a pro can tell you which after walking the perimeter.
Our process
- Step 1
Drainage assessment
We check grade, downspout placement, soil saturation, and surface flow patterns around the entire perimeter.
- Step 2
Solution plan
Some combination of regrading, French drains, downspout extensions, and surface drains.
- Step 3
Installation
Most drainage corrections take 1-3 days. Trenching is the bulk of the work.
- Step 4
Verification
We test with a hose or wait for the next rain to confirm water flows away from the home.
Frequently asked questions
Is drainage really the cause of my foundation problem?
Often, yes. Soil that's repeatedly saturated and then dried causes the worst expansion-contraction cycles. Fixing drainage doesn't repair existing damage, but it prevents the same problem from coming back after the piers are installed.
Should I do drainage work before or after foundation repair?
Ideally before, or at the same time. Doing it after means you've fixed the symptom but not the cause. If budget forces a phased approach, foundation repair first stops active damage. Drainage second prevents the next round.
Can I just install French drains myself?
For minor surface issues, sometimes. For perimeter drains around a foundation, get a pro. Depth, slope, and outlet placement matter more than the trenching itself, and a poorly installed French drain creates new problems instead of solving them.
How long does a French drain last?
Properly installed with the right gravel and filter fabric, 25-40 years before the gravel clogs and the system needs servicing. Failure usually comes from clogged outlets or damaged filter fabric, not the pipe itself.
Will drainage work tear up my landscaping?
Some, yes. French drains require trenches 18-30 inches deep. Most contractors restore the lawn surface, but established shrubs or large landscaping features in the trench path will be affected. The on-site assessment shows you exactly where the trenches need to go.
Do I need a permit for drainage work?
Usually not. Surface grading, French drains, and downspout extensions don't require permits in Bell or Coryell County. If your work involves connecting to a storm sewer or rerouting flow onto a neighbor's property, that may require approval. The contractor knows the local rules.
How much does a typical drainage correction cost in Killeen?
Most jobs in Bell County run $1,000-$5,000. A perimeter French drain on a typical home runs $3,500-$8,000 if installed alone. Regrading and downspout extensions together usually come in under $2,500. The exact cost depends on lot size, soil type, and how far water has to be routed to a safe outlet.
