Stravibase Spring* bearings are structural springs used for building base isolation, where an acoustic performance with a resonance frequency lower than 6Hz is required.

Stravibase Spring bearings have a static deflection ranging from 10 to 30 mm. Therefore, these bearings are only recommended for structures that are capable to deal with such a deflection variation during the construction process. If limited deflection during construction is required, pre-compressed spring solutions can be offered – please check our Stravibase SpringBox solution for more information.

Each Stravibase Spring consists of a single or double nested springs with a top and bottom cover plate, including an elastomeric anti-slip layer.
