Vibration isolation technology has moved on to the isolation of entire buildings rather than just building components. We have designed and manufactured Neoprene and Natural Rubber bearing pads to frequencies as low as 6 Hz and steel spring assemblies in the 0.75 to 2.00 inch (19 to 50mm) deflection range in individual capacities of 1,000,000 lbs. (454,000 kgs.) Both techniques are used to keep ground vibration and noise out of buildings close to railroads, subways, heavy traffic or industrial impact.

Rubber bearings conform to Government codes and testing. Life expectancy is 50 or more years. While they are generally not replaceable, replacement can be built into the installation at a small added cost if the locations remain accessible.
Spring mountings are often partially pre-compressed and automatically released as building weight is added during construction. We prefer the technique of structural spring support with removable spacers after the mountings have been hydraulically compressed to assume the building weight.
