Protect Your Property During Seismic Events

Foundation retrofit, also known as earthquake retrofit or brace+bolt retrofit, enhances the connection between a building’s wooden frame and its concrete foundation. Seismic codes mandated stronger foundation-to-wooden frame connections. In modern retrofitting, large anchor bolts are strategically placed throughout the foundation, firmly securing the structure. This prevents buildings from sliding or shifting away from the foundation during seismic events, thus improving their resilience.

Why You Need Foundation Retrofitting In California

Southern California is known for its susceptibility to seismic activity, making foundation retrofit in Los Angeles a crucial investment for property owners. Retrofitting significantly improves your structure’s ability to withstand the forces generated by earthquakes, offering enhanced protection of both your property and its occupants. With a history of significant seismic events in the region, proactive foundation retrofitting is a prudent measure to minimize damage, maintain property value, and ensure the structural integrity of your building during earthquakes.

The History Of Foundation Retrofitting

Foundation retrofitting has evolved over the years in response to seismic research and the need to enhance structural resilience. Historically, buildings constructed before the 1960s were often inadequately secured to their foundations. However, increasing seismic risks in California led to the development of retrofit techniques, such as installing anchor bolts and shear walls. Consequently, codes and standards were established to make retrofitting a crucial practice to ensure the safety and stability of structures in Los Angeles.

Reasons For Foundation Retrofitting:

  • Enhanced seismic resilience
  • Reduced risk of structural damage
  • Increased safety for occupants
  • Preservation of property value
  • Compliance with modern building codes
  • Peace of mind during earthquakes

How Foundation Retrofitting Protects Your Property

During an earthquake, the ground beneath your property can shake violently, subjecting your home to lateral and vertical forces. Without proper reinforcement, this seismic motion can lead to structural damage.

Through the strategic installation of anchor bolts, shear walls, and other structural enhancements, a foundation retrofit in Los Angeles secures your building to its foundation. This helps distribute seismic forces evenly throughout the structure, minimizing the risk of detachment or collapse and protecting your property.

How Foundation Retrofitting Is Done

The foundation retrofitting process is tailored to your property’s unique characteristics. During your initial inspection, our experts will consider factors like your home’s construction date, location, existing foundation condition, and the impact of past seismic events. Before we proceed, we must ensure that your foundation is stable. If your foundation requires repairs due to poor construction or prior seismic damage, those issues are addressed first. Retrofitting conventional raised foundations generally consists of adding anchors between the wood sill plate and concrete foundation with large plate washers, sometimes side anchoring plates are used when there is insufficient room to drill down.

Once the sill plate is attached, there is a framing connection from the floor joist framing to the sill plate and sometimes additional wood blocking is needed for this. If your home has cripple walls (short wood framed walls), these will be reinforced with plywood for lateral strength. It’s important to select the right method for successful seismic retrofitting. Our foundation repair experts carefully inspect your property to determine the most appropriate technique of foundation retrofit in Los Angeles to ensure its resilience and longevity.
