About Earthquake Protection Systems

Earthquake Protection Systems’ mission is to apply our advanced seismic isolation technology to the design and construction of resilient and sustainable facilities that can function after an earthquake. Using multi-stage seismic isolation, it is now economical to design facilities to protect contents, non-structural components, and structures from damage during the most severe earthquakes.

New construction can cost less than minimum code designs based on traditional ductility design. Consequently, designing for continued functionality is now an economical and practical alternative to code designs that implement only the minimum life safety standards as required by law. EPS is the world leader in seismic isolation design and manufacture. We have the highest engineering qualifications, most technologically advanced products, the broadest implementation experience, and the most comprehensive testing. We respond to the worldwide demand for seismic isolators with on time delivery at competitive prices.

Our Facility
Our Facility

The EPS manufacturing facilities occupy 520,000 sq. ft. of building space, located on a 30 acre property located in Vallejo, California, owned by EPS. EPS has complete in-house fabrication capability, enabling short lead times for isolator manufacture. We have manufactured the world’s largest seismic isolation isolators, and have a production capacity of over 5,000 seismic isolators per year, in a wide range of sizes.

Our isolator testing capabilities exceed those of any other facility. Real time earthquake simulation testing is typically performed for every isolator, providing realistic verification of the isolator design properties and capacities. Isolator tests may be performed in either a 15,000 kip capacity test machine, or a 2000 kip capacity test machine.

EPS has three principal structural engineers, each with more than 20 years full-time experience in the design and implementation of seismic isolation. Each principal engineer has designed and implemented seismic isolation for major, critical applications. A principal engineer works with every customer to design the most cost-effective and best performing seismic isolation solution for his or her application.

Victor Zayas, Ph.D., P.E.



Victor Zayas is the Chief Executive Officer responsible for business and operations management. He oversees product development, manufacturing, testing, and quality control. He developed the Friction Pendulum™ isolator technology and materials, manufacturing and testing methods.

EPS Integrated Engineering and Manufacturing

EPS offers seismic isolation solutions and provides engineering support services to project engineers to help them evaluate the technical and cost benefits that our expert seismic isolation engineering and products can bring to a construction project. We develop application-specific seismic isolation solutions, and isolator designs with guaranteed prices. We submit these to the engineer and owner so they can evaluate and select the preferred seismic solution and isolator manufacturer early in the project design process.

EPS’ seismic isolation solutions achieve improved seismic performance at reduced construction costs.After EPS is selected for an application, EPS seismic isolation engineering experts will work with the project engineer to optimize the seismic isolation solution, and develop isolator designs and installation details that meet the performance criteria, and reduce the cost of construction. Once the isolator designs are complete, prototype testing is performed, and a complete signed and stamped engineering report is submitted by EPS for the isolation system design, isolator manufacture, and testing. All EPS seismic isolation solutions, and isolator designs are the copyrighted and proprietary intellectual property of EPS.

EPS isolators are manufactured and tested in strict compliance with the EPS ISO 9001:2015 specifications, which are the only specifications that apply to the isolator manufacture and testing. The proper implementation of the isolation system into the project design and construction is the responsibility of the project design engineer. Isolators used for construction are sold at the guaranteed prices in accordance with standard EPS terms and conditions.
