How Do You Know?
You may have a few small things that could lead to a quick fix before your foundation needs major work.

Types of Homes Requiring Seismic Upgrades

Among the different housing types, raised foundation houses typically have a crawl space beneath the ground floor, making them vulnerable to seismic movements. These houses often feature a wooden frame resting on piers or short walls, requiring reinforced connections and foundation anchorage for improved stability. Stem-wall houses, on the other hand, have a concrete perimeter foundation with stem walls supporting the floor joists. Retrofitting such structures may involve strengthening the connections between the walls and the foundation to mitigate earthquake risks.

Raised Foundation Houses

Raised foundation houses necessitate a resilient approach to reinforcement, often incorporating base isolators and supplementary dampers to mitigate seismic impacts effectively.

Base isolators are critical in seismic retrofitting projects for homes with raised foundations. These devices decouple the structure from the ground motions of an earthquake, reducing the transmission of damaging forces. Damping systems, such as viscous dampers, can absorb and dissipate seismic energy, further enhancing the building’s resilience. Our engineers may also implement shear walls, bracing systems, and strengthening techniques to fortify the structure and prevent collapse during seismic events. By combining these strategies, raised foundation houses can achieve higher earthquake resistance and structural integrity.

Stem-Wall Houses

Stem-wall houses face challenges such as soft-story failure, which can be addressed by implementing tuned mass dampers and other retrofit solutions to enhance structural stability.

Soft-story failure in stem-wall houses is a concern due to the weaker lower stories, making them more susceptible to collapse during seismic events. To combat this, our engineers often recommend the installation of tuned mass dampers, which help absorb and dissipate energy from vibrations, reducing the risk of structural damage.

Retrofitting methods like adding steel frames or shear walls can also be used to strengthen the lower levels of stem-wall houses and mitigate the potential for soft-story failures. These retrofit solutions work towards improving the overall structural integrity of the building, providing greater resilience against seismic forces.

Cripple-Wall Houses

Cripple-wall houses benefit from upgrades that involve active control systems to strengthen weak connections and improve the overall seismic performance of the structure.

Integrating these active control systems into retrofitting helps ensure the building’s resilience to seismic activities. Along with these systems, reinforcing weak connections such as foundation anchorage, shear walls, and roof-to-wall connections is essential.

By addressing these vulnerable points, the house’s structural integrity can be significantly enhanced, reducing the risk of damage during an earthquake. Strengthening these areas through targeted upgrades and enhancements can greatly improve the overall safety and longevity of the building.

Post & Pier Houses

Homes with post & pier foundations are susceptible to risks like land liquefaction and landslides, necessitating the expertise of geotechnical engineers to assess the site conditions and implement appropriate retrofitting measures.

With their elevated structures resting on shallow foundations, post & pier houses face unique challenges when it comes to geological hazards. Liquefaction, a phenomenon where saturated soil behaves like a liquid during seismic activity, poses a significant threat to the stability of these homes. Landslides, triggered by heavy rainfall or steep slopes, can also jeopardize the structural integrity of post & pier constructions. This is where our geotechnical engineers play a crucial role. By conducting thorough site evaluations and designing tailored retrofit solutions, our experts help fortify these vulnerable homes against the forces of nature.

Living in a hillside home can offer breathtaking views and a serene environment, but it also comes with inherent risks. One major concern is the susceptibility to ground movements due to the unstable nature of the terrain. In geological hazard zones, the threat of liquefaction and landslides looms large, posing dangers to both the structural integrity of the property and the safety of residents.

  • When seismic waves pass through the soil beneath a hillside property during an earthquake, it can cause the ground to temporarily behave like a liquid, a phenomenon known as liquefaction. This can lead to severe damage to the foundation and structure of the house, endangering the lives of those inside.
  • The steep slopes of hillside properties are more prone to landslides, especially in regions with heavy rainfall or seismic activity. These sudden movements of earth and rock can destroy homes and block roads and utilities, making evacuation and rescue efforts challenging.

To mitigate these risks, property owners in geological hazard zones must prioritize comprehensive seismic retrofitting solutions tailored for hillside homes. Retrofitting techniques such as reinforced foundations, slope stabilization measures, and drainage systems can significantly improve the resilience of these properties against liquefaction and landslides, ensuring the safety of residents and preserving the value of the real estate.

Methods for Retrofitting Homes

Various methods for retrofitting homes include structural support enhancements, reinforcement techniques, and retrofit solutions tailored to strengthen buildings and protect against seismic vulnerabilities.

Structural support enhancements play a crucial role in earthquake-prone regions, with options like base isolation and bracing systems helping to distribute forces. Similarly, reinforcement techniques such as adding steel frames or shear walls can significantly improve the building’s ability to withstand seismic activity. Retrofit solutions, including foundation upgrades and roof-to-wall connections, aim to mitigate damage and increase the overall durability of structures. By combining these diverse approaches, homeowners can fortify their residences and enhance their resilience to potential earthquakes.

Base Isolation Systems 

Base isolation involves separating a building or structure from the ground by placing isolators or bearings between the foundation and superstructure. This allows the building to move independently of the ground during an earthquake, reducing the transfer of seismic forces to the structure and minimizing damage. 

Bracing Systems 

Bracing systems are structural components that are designed to provide additional support and stability to a building’s foundation during an earthquake. These systems are typically made up of steel or reinforced concrete elements that are installed within the foundation of a building to help distribute the seismic forces and prevent structural damage.
There are several types of bracing systems that are commonly used in Southern California for seismic foundation reinforcement:

  1. Shear walls: Shear walls are vertical walls that are designed to resist lateral forces, such as those generated during an earthquake. These walls are typically made of reinforced concrete and are strategically placed throughout a building to provide structural support.
  2. Moment frames: Moment frames are steel or concrete beams and columns that are connected together to form a rigid frame structure. These frames can resist both lateral and vertical seismic forces and are commonly used in high-rise buildings and other large structures.
  3. Braced frames: Braced frames are steel or concrete frames that are braced with diagonal members to provide lateral stability. These frames are often used in buildings with open floor plans to provide flexible seismic resistance.
