CDM Stravibase Raft
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.
Main Benefits
- 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)
- Low creep behavior
- Easy and quick installation
Design Requirements
- Natural frequency required
- Isolation performance to be achieved
- Working dead and live loads
- Lateral and turning forces
- Available areas
- Lateral walls in the building perimeter
