From the field, the plant, and the shake table.
We run more than 1,000 tests a year to keep design, engineering and manufacturing on spec. These galleries show that work in progress.
Some of the unique design and engineering solutions DIS brings to every project.
Hospitals
Buildings isolated to remain operational immediately following an earthquake.
New Bridges
Cost reductions from smaller foundations is a key benefit.
Retrofitted Bridges
Seismic isolation is an economical method of retrofitting bridges.
New Buildings
The variety of buildings incorporating DIS isolators.
Retrofitted Buildings
Existing buildings are good candidates for seismic isolation.
Projects in Japan
DIS has completed over 170 projects in Japan.
Berry Street Project
Two isolated stories added to an existing three-story building.
Utah State Capitol
273 DIS isolators protect this historic structure.
3D Isolation
Low-mass isolation against vertical as well as horizontal accelerations.
New Installations
Isolators being installed in various new structures.
Retrofit Installations
