Foundation Repair

San Rafael’s diverse terrain, ranging from waterfront flats to rolling hills, creates a variety of foundation challenges for homeowners. In the flatlands, homes built on soft bay fill or expansive soils are prone to settling and soil movement, leading to foundation cracks and structural instability. In hillside areas, soil erosion and slope movement can further impact foundation health, necessitating professional repairs and leveling.

Seismic risks are also a concern in San Rafael due to its proximity to the San Andreas Fault. Earthquakes in the area can cause significant ground shaking and soil liquefaction, particularly in neighborhoods with soft soils. Older homes that lack modern seismic reinforcements are especially vulnerable. Seismic retrofitting—such as foundation bolting, cripple wall bracing, and shear wall installation—is essential to safeguard these homes during seismic events.

Drainage issues are common in San Rafael, particularly during heavy rains when water runoff can lead to soil erosion and hydrostatic pressure against foundation walls. Without proper drainage systems, homes are at risk of leaks, cracks, and long-term moisture damage. Installing solutions like French drains, sump pumps, and retaining walls helps manage water flow and protects San Rafael homes from foundation problems caused by water intrusion.
