What we fix
Foundation problems we see in San Marcos

Why foundations move in San Marcos
The soil this town is built on
A city level sample here returns urban fill, not a natural series. For the series, widen it to San Diego County, where the USDA survey reads Fallbrook at about 10 percent of the survey, with Cieneba and La Posta alongside it. By texture that survey runs 27 percent clay and 25 percent sand. Inside the San Marcos city limits, the USDA sample puts weighted linear extensibility at 3.74 percent, which is the figure USDA turns into a moderate shrink swell rating.
The housing stock
The typical house dates to 1994, and the single biggest block of the stock, 8,292 homes, went up in the 2000s. The 9,055 homes finished before 1980 are the ones where drainage was rarely engineered and backfill was rarely compacted. 26 percent of the housing here, 7,786 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Mortgages sit on 74 percent of the owner occupied homes in San Marcos.
