We Service Antioch!
Antioch’s warm summers and clay-rich soils combine to create significant stress on home foundations. The clay expands when wet and contracts during dry periods, causing movement that leads to cracks, settling, and structural misalignment. Homes in newer developments as well as older neighborhoods can be affected, often requiring leveling or foundation repair to address the problem.
The area is also vulnerable to seismic activity from nearby fault lines, including the Concord and Greenville Faults. Earthquake preparedness is crucial in Antioch, particularly for older homes lacking reinforcement. Seismic retrofitting can help secure the foundation and improve the structure’s ability to withstand seismic shocks.
Drainage is another key concern in Antioch, where heavy winter rains can cause water buildup around foundations, especially in flat or poorly graded areas. Without proper systems in place, water can lead to hydrostatic pressure, leaks, and soil erosion. French drains, sump systems, and appropriate guttering are essential tools to manage drainage and protect foundations.
