Foundation Repair in Harrison County, TX

Longview is the base for foundation repair in Harrison County, Texas, and the ground around the county's centre is mostly not the high-rated clay. In a sample of 49 places there, 2 fell on water. Of the other 47, 7 sat on soil rated high or very high for shrink-swell, and 3 of those were very high. The commonest soils were Bowie with 6 places, Mooreville with 4 and Keatchie with 3. Clay at those ratings swells when wet and shrinks when dry, which can lift and drop a slab or pier. That sample speaks for the middle of the county only, not for each town or street.

Water is the other fact worth knowing. In the same sample, 7 of the 47 land places sat inside the 1% annual chance floodplain. FEMA's flood map shows the zone for one address, so a homeowner looks up their own lot. A house with water standing beside it keeps the clay below damp. Census estimates put the median home at 1984, with 20.1% built before 1960 and 43.2% in 1990 or later. Older Texas homes lean toward pier and beam and newer ones toward slab as a rule of thumb, but foundation type is not something the census records.
