Why are homes in Los Angeles County sinking?
Los Angeles County features some of the most diverse—and challenging—geography in the country. From canyon estates to flat coastal grids, LA properties face a unique set of soil stressors.
For the iconic hillside and canyon homes of LA, the biggest culprit is "cut and fill" grading. To build a flat building pad on a steep slope, developers cut into the hillside and pushed the loose dirt outward to extend the lot.
Over the decades, gravity and heavy winter rainfall cause that "fill" dirt to slowly creep downhill, pulling the downslope edge of your foundation, patios, and pool decks with it.


In flat coastal areas like Long Beach and Santa Monica, homes sit in known "liquefaction zones." Here, sandy, water-logged soils can completely lose their structural strength during seismic activity or heavy flooding, causing heavy concrete slabs to sink rapidly.
LA is famous for its tight property lines. If your home was built close to your neighbor's, or if you have invested heavily in zero-lot-line hardscaping, traditional concrete underpinning is often impossible without destroying your property (or your neighbor's).
Geobear’s geopolymer injection requires only a 5/8-inch hole. We inject expanding resins that bind loose sandy soils together and compact failing "fill" dirt on hillsides, stabilizing your sinking floors and cracking walls without the need for destructive trenches.
Areas we serve across Los Angeles County
We provide fast, non-disruptive foundation repair to homeowners throughout the entire LA region.
