These photographs represent some of the unique design and engineering solutions that DIS brings to every project.
3D Isolation
DIS has developed technology which provides low mass seismic isolation against vertical as well as horizontal accelerations.
Berry Street Project
This unique project added 2 isolated stories to an existing 3 story building.
Hospitals
These buildings are typically isolated so that they are operational immediately following an earthquake.
New Installation
Isolators being installed in various new structures.
Retrofit Installation
Installation of isolators in existing structures.
Projects in Japan
DIS has completed over 170 projects in Japan.
New Bridges
Cost reductions resulting from smaller foundations is a key benefit of bridge isolation.
New Buildings
These photos show the variety of buildings incorporating DIS isolators.
Videos
Every year DIS conducts more than 1,000 tests to ensure the quality of our design, engineering and manufacturing processes. Videos include tests of our base isolators, floor isolation and 3D isolation systems.

Viscous Wall Dampers
Viscous Wall Dampers
VWDs are installed in taller, more flexible structures to absorb energy and reduce seismic accelerations and inter-story drift.
Non-Structural Isolation
3D Isolation
DIS Engineers have developed a system which provides X, Y, and Z seismic isolation.
Non-Structural Isolation
It's not always practical to isolate an entire structure.
3D Isolation Test
Test of the new DIS Technology which provides low mass seismic isolation aganist vertical as well as horizontal accelerations.
Floor Isolation Testing
A full suite of MCE earthquakes were tested.
Floor Isolation
DIS has developed this technology to protect the contents of non-isolated buildings.
Floor Isolation Shake Table
DIS Shake table tested its system extensively at the University of Nevada, Reno.
