A Drought Watering Checklist for Your Slab Foundation in Smith County

Updated November 2026 · 6 min read

When the yard turns brown in July and a gap opens between the soil and the edge of the slab, many Tyler homeowners wonder whether they should water the foundation. Steady watering can help keep soil from shrinking away from a slab in a long dry spell. It has to be done evenly, within the city's water rules, and with clear expectations. Here is a checklist for the hot months.

Why summer is hard on Smith County slabs

Tyler averages about 42 inches of rain a year, but July is the driest month (2.1 inches) and the city sees about 98 days of 90°F-plus heat (NOAA 1991–2020 normals, Tyler Pounds Regional Airport). June is the wettest month on average, so the soil often goes from wet to dry in a few weeks as summer starts.

Long droughts make it worse. In 2011, all of Smith County was in exceptional drought for 21 weeks (U.S. Drought Monitor), and Tyler had 46 straight days of 100°F-plus heat that summer (NOAA). In 2022, extreme drought covered up to about two-thirds of the county, and 2026 has been dry too: on the November 3, 2026 U.S. Drought Monitor map, about 90% of Smith County was in severe drought. Tyler got just 25 inches of rain in 2011 and more than 68 inches in 2015 (NOAA).

Soil matters as well. Much of Tyler and Smith County is mapped in sandy and loamy soils, many over red clay subsoils with moderate shrink-swell potential (USDA NRCS). That mix means poor drainage, erosion and long dry spells can all move a foundation. Where the subsoil is clay, it shrinks as it dries and can pull away from the slab edge, which can let the edge settle. On deep sandy soils, shrinkage is less of a concern than water washing soil out, so drainage may matter more than watering. Your lot may have either, or both.

Before summer

Checklist: get ready in spring

• Walk the house and photograph every crack inside and out, with the date. These are your baseline.
• Mark the ends of any cracks in brick or drywall with a pencil line and date.
• Note which doors stick now. If they stick later in summer, you will know.
• Clean gutters and check that downspouts carry water away from the house.
• Check that soil and mulch slope away from the slab, not toward it.
• Find out the current Tyler Water Utilities watering stage and allowed days for your address.
• Buy a soaker hose long enough to circle the house, plus a hose timer if you want one.

July to September

Checklist: during dry spells

• Follow Tyler Water Utilities' current watering rules. If the city limits watering, foundation watering may be limited too, so do not water outside the allowed days or times.
• Lay the soaker hose a short distance out from the slab edge on bare soil or under mulch, not against the concrete.
• Water all sides of the house, not just the side that looks driest. Uneven watering can cause uneven movement.
• Water slowly and in moderation. The goal is soil that stays slightly moist, not mud or standing water.
• Water in the early morning or evening to cut evaporation.
• Keep an eye on gaps between the soil and the slab. If a gap is shrinking, the soil is taking up water.
• Recheck your crack marks and sticking doors once a month.
• Watch the water bill. A sudden jump unrelated to watering can point to a plumbing leak, which needs a plumber, not more water.

Trees, roots and shade

Tyler's woodland soils commonly carry shortleaf and loblolly pine, red oak, post oak, sweetgum and hickory, so many lots have big trees close to the house. Large pines and oaks near the house can dry out clay soil under a foundation in a drought. Roots tend to matter most where the subsoil is clay and less on deep sands.

• Give large trees near the house their own deep, slow watering in a drought, within the city rules, so they draw less from under the slab.
• Ask an arborist before cutting roots or removing a big tree next to the house. Sudden removal can change soil moisture too.
• When planting, keep new large trees well away from the foundation.
• Ask a foundation company whether a root barrier makes sense if roots are clearly under the slab edge.

After the rains

Checklist: in the fall

• Compare cracks and doors with your spring photos and notes.
• Note any cracks that partly closed after the rains. That is a sign of seasonal movement worth mentioning to a company.
• Clean gutters again once leaves and pine needles fall.
• Fix any spots where water pooled during the first big storms.
• If the same problems come back every summer, collect quotes over the winter, when schedules are often lighter.

When watering is not enough

If you see wide or offset cracks, floors that slope, or doors that get worse every summer, the foundation may already have moved. A repair company can measure floor elevations and explain the options, and an independent engineer can give an opinion not tied to a sale. Texas does not issue a state license for foundation repair companies, so check experience, insurance, written warranties and reviews yourself, and ask whether a licensed professional engineer (PE) designs or signs off on the repair.
