Why do Victoria foundations move?

The Texas State Historical Association places Victoria County on the Coastal Plain of southeastern Texas, with most of the county nearly level to gently rolling coastal prairie and dark clay loams and clays. The northwest corner reaches into the Post Oak Belt, with sandier soils. The county drains toward Lavaca Bay through Garcitas, Arenosa and Placedo creeks in the northeast, and to the Guadalupe and San Antonio rivers and Coleto Creek in the southwest.

The clays are the issue. Smectite-rich clay with high shrink-swell potential underlies most of the city of Victoria. USDA's official description of Laewest clay, whose type location is near Placedo, classifies it as a fine, smectitic Vertisol formed in clayey Beaumont Formation deposits on flat coastal plain. When dry, it opens surface cracks 1 to 5 centimeters wide, and centimeter-wide cracks commonly extend to about 1.2 meters in summer. It also forms gilgai, with small natural mounds 15 to 30 centimeters higher than the dips between them. That's the ground many houses in the county sit on.

The Texas Department of Licensing and Regulation explains the consequence in its technical bulletin on residential foundations over expansive soil: when soil moisture is high, the soil heaves and lifts a building; when it's low, the soil shrinks and the building settles. The bulletin says water must drain away from the house on all sides and points to drainage, plant choices, sprinkling practices and long-term maintenance as ways to limit moisture swings.

Victoria's climate keeps those swings going. Normals for 1991 to 2020 at Victoria Regional Airport show about 41.2 inches of precipitation a year and an average July high of about 94.6°F. Heavy rain from Gulf storms can soak the clay, and a long hot summer can dry it out again.

Settling, heaving, or just seasonal?

Settlement is part of the foundation going down, usually an edge or corner where the soil dried out, wasn't compacted well, or lost support. Piers are the usual repair.
Heave is part of the foundation coming up, often the middle of a slab, because the clay underneath got wetter. Plumbing leaks and water ponding against the house are common causes. Stopping the water is the fix, not edge piers.
Seasonal movement is the house rising and falling with wet and dry spells. Steadier moisture around the foundation reduces it.

A floor elevation survey tells them apart, and two surveys taken in different seasons tell you even more.

Which warning signs matter most?

Stair-step cracks in brick that are wider at one end
Doors and windows that start to stick or won't latch
Sloping floors, or tile cracked in a straight line
Gaps at baseboards, crown molding, window frames or the garage door
Cracks that reopen after being patched

What are the repair options?

Settled slab homes are usually supported with piers under the perimeter beam, most often pressed concrete or steel push piers, sometimes helical or drilled piers. Pier-and-beam homes are usually leveled from the crawl space with new shims, reset or added interior piers and framing repair, plus perimeter piers where the outside beam has dropped. Drainage and moisture control belong in almost every plan. See how pier types compare.

Does Texas license foundation repair companies?

No. The Texas Residential Construction Commission, which registered home builders and remodelers, was abolished when its law expired on September 1, 2009, according to the Texas Sunset Advisory Commission, and TDLR's licensing programs don't cover general contractors or foundation repair. That puts the checking on you and on the city.

Inside the city of Victoria, the Development Center handles building permits, plan review, inspections and floodplain management. The city's building guide tells residents to contact the Development Center to find out whether a change needs a permit, and says contractors need a City of Victoria contractor's license unless a homeowner is working on their own homestead. Outside the city, in places like Inez, Bloomington and Placedo, Victoria County requires floodplain development permits for development in the floodplain.

For an independent opinion, a licensed professional engineer can evaluate the house or design the repair. Licenses can be checked with the Texas Board of Professional Engineers and Land Surveyors.

What about flood zones?

The City of Victoria participates in the National Flood Insurance Program and enforces a flood damage prevention ordinance. Its building guide says most man-made changes in the floodplain require a permit and that most improvements there require a Texas licensed professional engineer or surveyor. You can check whether a property is in a mapped flood zone through FEMA's Flood Map Service Center.

How should I compare bids?

An elevation map, and a clear explanation of the cause
A numbered pier layout and the reason the piers stop where they do
The pier type and what it's driven to (depth, pressure or torque)
A pier log delivered after the job
What drainage work is included or recommended
Who requests Texas811 locates, who pulls any permit, and whether the contractor holds a City of Victoria contractor's license for work in the city
Warranty length, what it covers (piers, readjustment, cosmetic damage) and whether it transfers to a buyer

What can homeowners do?

Keep gutters clear and carry downspout water well away from the slab
Keep soil sloping away from the house on every side
Water evenly near the foundation during long dry spells
Watch the water bill for unexplained jumps
Keep a dated log and photos of cracks and sticking doors

Common questions

Why are foundation problems so common in Victoria, Texas?

Most of the city sits on smectite-rich clay with high shrink-swell potential. It swells after heavy Gulf rains and shrinks and cracks deeply in hot, dry summers, and houses move with it.

Is a city permit needed for foundation repair in Victoria?

The city's building guide says to contact the Development Center to find out whether a change needs a permit. Floodplain properties have extra rules. Your contractor should know and pull any permit required.

How do I check a foundation contractor in Texas?

There's no state license to look up. In the city of Victoria, ask for their city contractor's license. Also ask about insurance, a written pier plan, a pier log and a transferable warranty.
