Why do Bell County foundations move?

Bell County is really two landscapes. The Texas State Historical Association describes the Balcones Escarpment running through the approximate center of the county from southeast to northwest. East of it is the Blackland Prairie, fairly level to gently rolling, with dark, clayey soils; Houston Black clay is the most common. West of it is the Grand Prairie, with rolling uplands cut by stream valleys, stony slopes in places, and loamy to clayey soils with limy subsoils. Temple is on the blackland side, Killeen and Harker Heights on the Grand Prairie side, and Belton sits near the line between them.

The blackland clays are expansive. USDA's official description classifies Houston Black as a fine, smectitic Vertisol formed from weathered calcareous mudstone, and notes that when it dries, cracks 0.5 to 4 inches wide extend a foot or more down and stay open 90 to 150 cumulative days in most years. Branyon, a closely related clay, was established as a soil series from Bell County's 1972 survey and cracks 20 inches or deeper. Smectite clays take up water and swell, then shrink as they dry.

The Texas Department of Licensing and Regulation sums up what that means for a house in a technical bulletin on foundations over expansive soil: soils with high moisture heave and lift a building, and low moisture lets the soil shrink and the building settle. The bulletin says water must drain away from the house on all sides and lists drainage, plant choices, sprinkling practices and long-term maintenance as ways to limit moisture swings.

The climate supplies those swings. Temple averages about 36.9 inches of precipitation a year, and July's average high is about 95°F. A wet spring, a long dry August and a stormy fall can take the clay through a full shrink-swell cycle in one year.

Settling, heaving or just seasonal?

Settlement is part of the foundation dropping, usually an edge or corner where the soil dried out, was poorly compacted, or lost support. Piers are the usual repair.
Heave is part of the foundation rising, often the middle of a slab, because the clay underneath got wetter than before. Plumbing leaks and water ponding against the house are common causes. Piers at the edges don't fix it; stopping the water does.
Seasonal movement is the house rising and falling with wet and dry spells. Steadier moisture around the foundation reduces it.

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

Which warning signs matter?

Stair-step cracks in brick that are wider at one end
Doors and windows that begin sticking or won't latch
Sloping floors, or tile cracked in a straight line
Gaps above baseboards, at crown molding, or at the garage door
Cracks that reopen after they've been patched

What are the repair options?

Settled slab houses 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 houses are usually leveled from the crawl space with new shims, added or reset interior piers and framing repair, with 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 regulated programs don't include general contractors or foundation repair. That leaves the checking to you and your city. The City of Killeen requires contractors to hold a city general construction registration before applying for permits. Temple's Building Permits & Inspections department and Belton's Planning Department, which uses the MGO Connect portal, handle permits in those cities. Ask your city whether your repair needs a permit before work starts.

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

How should I compare bids?

An elevation map, and the contractor's 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 and who pulls the permit
Warranty length, what it covers (piers, readjustment, cosmetic damage) and whether it transfers to a buyer

What can homeowners do themselves?

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 around Temple?

Much of Bell County, including Temple, sits on Blackland Prairie clays such as Houston Black, which shrink and crack deeply when dry and swell when wet. Hot summers and uneven rain keep that cycle going.

Is the ground different in Killeen?

Yes. Killeen is west of the Balcones Escarpment on the Grand Prairie, with clayey soils over limy subsoil and limestone. Clay layers and sloping cut-and-fill lots can still cause foundation movement.

How do I check a foundation contractor in Texas?

There's no state license to look up. Ask whether they're registered with your city where required, will pull any permit, carry insurance, and will give you a written pier plan, pier log and warranty.
