Foundation Underpinning Services
Strengthen shallow or compromised footings by extending the foundation deeper into supportive soil strata to handle increased building loads or slope movement.
About Our Underpinning Services
Foundation underpinning strengthens shallow or compromised footings by extending the foundation deeper into stable, load-bearing soil strata. Spring Valley General Construction provides professional underpinning services for both residential and commercial properties in Concord and the Bay Area.
Underpinning may be necessary when a foundation's original footings are too shallow for the soil conditions, when building loads have increased due to additions, or when slope movement has compromised the existing foundation. Our methods include concrete mass underpinning, footing deepening, and load-bearing reinforcement.
We carefully extend the foundation in sections to maintain structural stability throughout the process. Each section is excavated, filled with reinforced concrete, and allowed to cure before the next section is started, ensuring your building remains safe and supported at all times.
