Stravibase Raft* is a resilient continuous supporting bearing system specially designed for raft foundations to protect the building from external vibrations generated especially by external nearby transport infrastructures.
Stravibase Raft is available in a wide range of thicknesses for different isolation performances to meet natural frequencies as low as 10 Hz.
Available in different grades and shapes for a correct load tuning.
High resistance to the imposed actions during the installation and concrete pouring operations
Special shaped surface to reach high dynamic performances
Adaptable stiffness according to the applied loads
Stable long-term stiffness and dynamic performance
Low water absorption
High resistance to external factors as alkaline water (wet concrete)
