Earthquake Retrofit in San Diego County
Protection Begins With Engineering.
Your home. Its foundation. The soil beneath it. A stronger approach considers them together — so your retrofit is engineered for the individual home, not pulled from a one-size-fits-all checklist.

The Whole System Matters
Every Home Has Its Own Foundation Story
California earthquakes are not a question of if — they are a question of when. Millions of homes were built before modern seismic requirements and remain vulnerable to sliding, racking, cripple wall failure, and foundation movement.
Age, construction, soil conditions, and structural connections all shape a home’s response to an earthquake. Understanding those conditions is the starting point for a meaningful retrofit.
Sure Safe® brings the structure, foundation, and supporting ground into one engineering conversation — so the recommendation fits the home.

The Principle Behind the System
Our Seismic Engineering Philosophy
Seismic Engineering Philosophy
The objective of foundation engineering is not to create the most rigid structure. It is to create the most effective structural system.
Every foundation exists as part of a larger system consisting of the structure, the foundation, and the supporting soil. These components do not act independently; they interact continuously under both static and dynamic loading.
During an earthquake, the challenge is not to eliminate movement. That is impossible. The challenge is to manage how earthquake forces are transferred through the structure and into the supporting ground while maintaining a continuous structural load path.
Throughout the development of the Sure Safe® Engineered Foundation Systems, every design decision has been guided by one fundamental principle:
Dynamic forces should be managed, not merely resisted.
This philosophy guided the development of the original two-stage seismic foundation, the Steel Buttress Foundation System, and ultimately the VR-1 Foundation System. While each generation incorporated new engineering solutions, all were based on the same objective — to protect the structure by intelligently managing the transfer of loads between the structure, the foundation, and the supporting soil.
This engineering philosophy forms the basis of the work presented in this monograph.

Start With the Connections
Is Your Home Ready?
A foundation assessment looks beyond what you can see above ground. Key areas to review include:
Designed With Your Home in Mind
- Slide from its foundation
- Collapse cripple walls
- Shift laterally
- Damage floors, walls, and utilities
- Become unsafe to live in
A Solution That Fits Your Home
From Seismic Connections to a Complete Foundation System
Depending on your home’s structural condition, the right answer may be a targeted retrofit or a full engineered foundation upgrade. Every recommendation is based on the engineering needs of your home.

Engineered Seismic Retrofit
Review anchorage, cripple walls, and structural connections together to identify the work your home actually needs — including cripple wall reinforcement and foundation anchoring.

VR-1 Foundation System
An engineered foundation option for homes requiring a broader crawl-space foundation upgrade — a complete foundation replacement installed without lifting or moving the home.

Steel Buttress Foundation System
A foundation solution for manufactured homes, considered in relation to the structure and the supporting ground beneath it.

Proven Performance Since 1986
Tested by California’s Biggest Earthquakes
Sure Safe® foundation systems have protected homes through some of California’s most significant earthquakes. These real-world events validated the engineering concepts that still guide every system we design today.
