Stravibase VHS* very high stress bearings isolate buildings from vibration and structure-borne noise caused by trains or trams running nearby or underneath buildings. They are designed to support very large loads whilst being significantly smaller in plan dimensions than traditional elastomer bearings.
VHS bearings provide the same acoustic performance as standard elastomer bearings which are more than twice their size; thereby having a significant impact on a buildings structural cost.
They are quick and easy to install, thereby minimizing associated labor costs. Top and bottom plates can be added to suit the specific method of installation.
Our engineers will design a configuration of VHS to best suit the structural element requiring support.
If required VHS bearings can be designed to be replaced one at a time using our “frozen bearing technique”
Natural frequency required
Permanent and variable loads
Lateral and turning forces

Frozen Bearing Technology
Frozen Bearing Technology (FBT) technique allows us to replace elastomer bearings such as Stravibase VHS without disturbing the building’s structure; which may become necessary if there is a significant change in the imposed load.
