Stravibase SpringBox

Pre-compressed Spring Bearing

Stravibase SpringBox is a spring solution used for Building Base Isolation. It consists of a pre-compressed steel box hosting an arranged series of single or double (nested) structural springs.

Stravibase SpringBox is designed to meet natural frequencies between 2.5 Hz and 5 Hz, and is available in different sizes.

The use of the Stravibase SpringBox is recommended for constructions where a limited settlement is required during construction.

  • Easy & Quick Installation
