Foundation Repair in Gillespie County, TX

Foundation repair in Gillespie County, Texas, rests on soil that is mostly shrink-swell clay in the area around the county's centre. In a sample of 49 places there, 1 fell on water. Of the other 48, 33 sat on soil rated high or very high for shrink-swell, and 2 of those were very high. The commonest soils were Tarrant with 15 places, Purves with 10 and Luckenbach with 5. Where clay is rated high, it swells with rain and shrinks in dry spells, and that movement can lift or drop a slab. The sample covers the area around the county's centre only.

None of the 48 land places in the sample sat inside the 1% annual chance floodplain. That is a sample of the area, not a promise about one address, so a homeowner still checks FEMA's flood map for their own lot. Census estimates put the median home at 1991, with 18.0% built before 1960 and 51.1% in 1990 or later. In general, pier and beam turns up more in older Texas houses and slab in newer ones. The census does not track foundation type.
