Cracks in brick, sticky doors, or a slab that seems to shift with the seasons can feel unsettling. If you live in Fulshear, the clay soils under your home are likely part of the story. With the right moisture, drainage, and landscaping habits, you can reduce movement and protect your investment for the long run. This guide gives you practical steps, a homeowner checklist, and trusted local resources so you can take confident action. Let’s dive in.
Understanding Fort Bend’s clay soils
Many parts of Fort Bend County sit on expansive clays that swell when wet and shrink when dry. In Fulshear, these seasonal changes can stress slabs, driveways, and patios. You may notice hairline cracks, doors out of alignment, or uneven floors after long wet spells or droughts.
Local rainfall patterns can amplify the effect. Heavy storms followed by dry heat create rapid moisture swings in the soil band near the foundation. Extension guidance from the Texas A&M AgriLife Extension and soil mapping through the USDA NRCS Web Soil Survey point to steady moisture and reliable drainage as your best preventive tools.
Keep soil moisture consistent
Rapidly changing moisture near your foundation increases shrink‑swell movement. Your goal is a steady, moderate moisture level in the soil around the slab.
How to water the foundation
- Use soaker hoses or drip lines 12–18 inches from the foundation, set to low flow for slow, even soaking.
- Add a moisture‑sensing timer or controller so you can keep schedules consistent.
- Adjust seasonally. Cut back during wet weeks. Increase frequency during prolonged heat or drought.
Mistakes to avoid
- Do not overwater to the point of standing water near the slab.
- Do not place soakers right against the foundation.
- Do not set and forget run times. Recheck settings as weather changes.
Extension resources emphasize that moisture control is preventive, not a cure for structural issues. Combine this step with proper drainage and grading for best results. For general guidance on soils and foundations, start with the Texas A&M AgriLife Extension.
Manage gutters and downspouts
Roof runoff can dump hundreds of gallons around your home during a single storm. If it pools at the foundation line, expect bigger moisture swings.
- Keep gutters clean so they can perform in heavy rain.
- Extend downspouts several feet away onto splash blocks or into rigid extenders that drain to a safe area.
- Inspect after storms to confirm extenders stayed put and water is not flowing back toward the house.
Local drainage rules stress getting water away from the structure. If you need to connect to a storm drain or make changes at the curb, check with Fort Bend County Engineering and Drainage or the City of Fulshear for permit guidance.
Check grading and surface drainage
Your yard’s slope should move water away from the slab, not toward it. The International Residential Code calls for positive drainage away from the foundation. A common standard is a minimum 5 percent slope, which is about a 6‑inch drop in the first 10 feet.
- Walk the perimeter after rain and look for ponding within 10 feet of the slab.
- Identify low spots or hardscapes that funnel water toward the house.
- Regrade soil, install shallow swales, or add channel drains to create a reliable path for water to exit.
For code context, review the International Residential Code requirements on grading and confirm adoption details with the county or city.
Quick slope check at home
- Place a 10‑foot straight board on the ground with one end against the foundation.
- Put a level on the board. Raise the end away from the house until level.
- Measure the gap at the far end. Aim for about 6 inches or more to meet the typical 5 percent slope guidance.
Plan landscaping and irrigation zones
Trees and large shrubs can pull moisture from clay soils. That can lead to uneven drying near the foundation.
- Keep large, water‑hungry trees at a sensible distance from the slab.
- Avoid saturating beds next to the foundation while the lawn stays dry. Design zones so you can control them separately.
- Watch for roots near the foundation and adjust watering to reduce sharp moisture contrasts.

Fulshear homeowner checklist
Use this simple routine to stay ahead of issues.
Weekly or after storms
- Clear leaves and debris from gutters and downspouts.
- Confirm downspout extensions and splash blocks are positioned and draining away from the slab.
- Walk the perimeter and look for ponding within 10 feet of the foundation.
Monthly or seasonally
- Test your foundation watering system and adjust run times for current weather.
- Recheck grading and fill new low spots. Verify the slope still moves water away.
- Review landscaping growth and irrigation coverage near the foundation.
Quarterly or annually
- Photograph interior and exterior areas where you have noticed movement. Track changes by date.
- Schedule a professional gutter inspection if you see persistent overflow or sagging.
- Review FEMA and county maps if drainage patterns on or near your property have changed.
When to call a professional
Pay attention to new or rapidly growing cracks, doors or windows that suddenly stick, or ongoing ponding near the slab. Also watch for water intrusion into any below‑grade areas or soils that stay saturated for days.
- Geotechnical or soils engineer: soil testing and moisture recommendations.
- Structural engineer: evaluation of structural movement.
- Licensed foundation contractor: repairs or stabilization when engineering recommends it.
- Local permitting staff: grading or drainage changes that require approvals.
For consumer guidance on repairs and contractors, consult the Texas Department of Insurance.
Local maps and resources
Use these tools to understand your soil, drainage, and flood context before you make changes.
- USDA NRCS Web Soil Survey to view your property’s soil series and clay characteristics.
- FEMA Flood Map Service Center to check floodplain status and review advisory maps.
- Fort Bend County Engineering and Drainage for county rules, drainage standards, and permits.
- City of Fulshear for municipal permits and public works.
- Texas A&M AgriLife Extension for home landscape, tree, and foundation moisture best practices.
Next steps
Thoughtful moisture control and dependable drainage can materially reduce movement in Fort Bend’s clay soils. Start with consistent foundation watering, reliable gutter extensions, and positive grading. Track what you see each season and bring in the right professional if signs escalate.

FAQs
What is the best slope away from my Fulshear foundation?
- A common guideline is about a 6‑inch drop over the first 10 feet, which equals roughly 5 percent. Confirm local code and site conditions before making changes.
How far should downspouts discharge from the slab?
- Several feet away is a typical target, and the water path must continue to flow away from the house. Inspect after storms to confirm drainage is positive.
Can watering alone prevent foundation problems on clay soils?
- Consistent moisture reduces shrink‑swell movement, but it is not a cure. Pair it with good grading, gutter management, and timely professional evaluation.
Should I regrade my yard myself in Fort Bend County?
- Minor touch‑ups are often DIY. Larger changes or any work that affects neighbors or connects to drains should involve professionals and local permitting.
How do I check if my Fulshear home is in a floodplain?
- Use the FEMA Flood Map Service Center and verify with county resources. Extra rules can apply in mapped flood areas.
