Foundation repair in Schertz and Selma, TX
Schertz and Selma sit east of I-35 on the San Antonio end of the corridor, where clay soil and Cibolo Creek shape the ground. Many subdivisions are decades old now, and their slabs show it.
Typical ground Mostly clay
A rough guide to the usual ground in town. Your lot can differ from the next street.
Why homes move here
On this side of the escarpment the soil is mostly clay. It swells in wet years and shrinks in dry ones. Many Schertz and Selma neighborhoods were built over the last few decades, so their slabs have been through several drought and flood cycles. Cracks in the brick, doors that stick and floors that slope are the usual signs.
Common causes here
- Clay that cycles between wet and dry
- Mature trees that have grown close to the slab
- Drainage that worked when the house was built and has changed since
- Plumbing leaks under the slab
- Soil that was compacted unevenly when the pad was built
Three counties
Schertz and Selma sit where Bexar, Comal and Guadalupe counties meet. Depending on the address, the city and county rules for permits and drainage can differ from a neighbor's a few streets away. Ask the company which jurisdiction applies to you and who files any permit.
Post-tension slabs
Many Texas slabs are post-tensioned, which means steel cables inside the concrete are pulled tight to hold it together. Drilling or cutting into a slab without locating those cables can be dangerous and can damage the foundation. Ask whether your slab has them and how the company will find them before it digs or drills. See slab foundation repair.
Growth, creeks and county lines
- Schertz is a city in Guadalupe, Bexar and Comal counties, and Selma also has land in all three. That is why permit and drainage rules can depend on your exact address.
- Schertz grew quickly. Its population went from 18,694 in 2000 to 42,002 at the 2020 census, so many homes here are newer.
- Selma incorporated in 1964 and has grown fast along I-35 since 2000. Its population roughly doubled between the 2010 and 2020 censuses.
- Cibolo Creek runs past both cities and forms part of the eastern boundary of Bexar County. An early name for the Schertz settlement was "Cut Off", because floods on Cibolo Creek cut it off.
For your house, two things follow: a home near the creek or in a low part of a subdivision may deal with more water after storms, and county lines can change which rules apply. Check both before paying for repairs.
Newer slabs and builder warranties
Because so many homes here are fairly new, start by looking at your closing paperwork. If a builder structural warranty is still active, it may require you to file a claim before any outside company does work. Keep dated photos and notes of any cracks or doors that change, since those records help with a claim and with any inspection later.

Schertz and Selma questions
Which county's rules apply to my house?
It depends on the address. Your tax bill or city utility account shows which city and county serve you. Ask the company to confirm it before it files for a permit.
Does a post-tension slab change the repair?
It can. Piers are still used, but crews must locate the cables first and avoid cutting them. Ask how the company handles post-tension slabs and whether the crew has done it before.
What should I have ready when the inspector comes?
Dated photos of cracks, notes on which doors stick and when, any builder warranty papers and the original soil report if you have one. Also mention whether your lot drains toward the house or toward Cibolo Creek after heavy rain.
Is my home near Cibolo Creek more likely to have foundation trouble?
Not automatically. But homes near a creek or in low spots may get more water after storms. Check your lot's flood map and where your yard drains, and mention it when you request an inspection.
