How the Assessment Works
Enter Your DFW Address
We look up your exact location in the USDA Web Soil Survey database to pull soil type, drainage class, and infiltration rate specific to your property.
Describe Your Drainage Symptoms
Tell us what you observe — standing water after rain, soggy spots, water pooling near the foundation, or erosion — to help us weight your risk factors accurately.
Tell Us About Your Property
Yard slope, lot age, impervious surface coverage, and proximity to the foundation all affect drainage performance and influence the recommended fix.
Get Your Personalized Risk Score and Recommendations
Receive a scored drainage risk assessment with specific solution recommendations matched to your soil type, symptoms, and property characteristics.
Why DFW Properties Need Drainage Assessment
Blackland Prairie Clay Expands and Contracts Dramatically
The Blackland Prairie clay soil that covers most of the DFW Metroplex is one of the most expansive soil types in the country. When wet, it swells significantly. When dry, it shrinks and cracks. This repeated movement puts stress on underground pipes, shifts irrigation heads, and destabilizes hard surfaces — making proper drainage the single most important factor in long-term property maintenance.
Poor Drainage Is the Leading Cause of Foundation Damage in North Texas
Standing water near a DFW slab foundation causes uneven soil expansion on one side of the structure. As clay swells under saturated areas and shrinks under dry areas, slabs experience differential settlement — the primary driver of cracked foundations, sticking doors, and sloping floors. Addressing drainage before foundation damage occurs costs a fraction of structural repair.
North Texas Subdivisions Are Built for Appearance, Not Water Flow
New construction and suburban lot grading in DFW often prioritize aesthetics over drainage. Flat lots, compacted fill soil, and minimal grade create conditions where even moderate rainfall produces standing water. In established neighborhoods, decades of soil settling and landscaping changes can reverse original drainage intent entirely.
DFW Clay Soil Infiltration Rates of Only 0.2 to 0.4 Inches Per Hour
Heavy DFW clay soils absorb water at just 0.2 to 0.4 inches per hour — far slower than typical rainfall rates during Texas storms. This means most rain water cannot enter the soil fast enough and becomes surface runoff. Without a designed drainage system, that water has nowhere to go except toward the lowest point on the property, which is often the foundation or a neighbor's yard.
Uses USDA soil survey data specific to DFW addresses — not generic regional estimates. Your risk score reflects the actual soil conditions mapped to your lot.
Frequently Asked Questions
What causes drainage problems in DFW?
The Blackland Prairie clay soil that underlies most of DFW has extremely low infiltration rates. When it rains, water can't absorb quickly enough and pools on the surface. New construction often compounds this by compacting soil and altering natural drainage patterns.
Can poor drainage damage my foundation?
Yes. Standing water near a DFW home's slab foundation causes the clay soil to expand unevenly, leading to differential settlement. This is one of the most common and expensive structural issues in North Texas.
What drainage solutions work in DFW clay soil?
French drains, channel drains, dry wells, and regrading are common solutions. The right fix depends on your specific soil conditions, yard slope, and where water accumulates — which is exactly what this assessment helps identify.
How accurate is this assessment?
The tool uses real USDA soil survey data specific to your address. It analyzes soil drainage class, infiltration rate, and shrink-swell potential to calculate your risk score. For a definitive diagnosis, we recommend an on-site evaluation.
