California

Serving The Golden State since 1999

California’s diverse geology and dry climate—ranging from clay-heavy soils in the north to sandy, unstable ground in the south—create persistent challenges for home foundations and concrete surfaces. Combined with seismic activity, drought conditions, and shifting moisture levels, these soil and climate factors often lead to foundation cracks, sinking concrete, and deteriorating crawl spaces. Groundworks proudly serves homeowners in Fairfield, San Jose, Riverside, and surrounding areas with expert foundation repair, crawl space encapsulation, and concrete lifting solutions tailored to California’s complex ground conditions. Backed by BBB A+ accreditation and a team of certified field inspectors offering free, no-obligation inspections, we provide proven, permanent repairs that restore safety and value to your home. Whether you’re navigating soil movement or seismic stress, Groundworks is here to protect your home from the ground up.
