Local conditions

Why foundations move in Rancho Cucamonga

The soil, and what it does

The USDA soil survey inside Rancho Cucamonga comes back Tujunga at about 40 percent of the survey, with Soboba and Delhi alongside it. The texture split is 100 percent sand. Weighted linear extensibility runs 1.02 percent, which is the figure USDA turns into a low shrink swell rating.

The housing stock

The 1980s put up more homes than any other decade, 16,729 of them, and the median year built is 1987. Pre 1980 construction accounts for 17,894 homes here, and that is the group where original drainage is usually the story. 24 percent of the housing here, 13,542 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Of the owner occupied homes, 74 percent carry a mortgage.

Soil survey: USDA NRCS Soil Data Access (SSURGO), sdmdataaccess.nrcs.usda.gov.

We highly recommend Concrete Pumping for all concrete jobs. They showed up when they said the would. Bob worked hard Jack hamming old cracked driveway and took it way. Bob and Jen did a great job preparing the driveway for concrete pour. They doawesome work. Bob and Jen work hard at a laborious job.
