Jack-up System
Stravifloor Jackup* is a floating floor system with reinforced steel boxes cast into concrete. Once the concrete has cured, the isolated slab is raised off the structure to the required void depth, reducing the risk of acoustic bridging between the floating floor slab and the subfloor. Stravifloor Jackup boxes allow for easy adjustment of the final height as well as replacement and inspection of isolators, should the use of the room or load conditions change in the future.
Special, insulation material can be installed in the avoid a standing wave in the air void (which may cause noise breakthrough at high frequencies).
Stravifloor Jackup boxes have an extremely high load capacity and, therefore, allow for larger spans and fewer support points than traditional jack-up systems, to provide a cost-effective solution. Stravifloor Jackup reduces the risk of acoustic bridging between the floating floor slab and the subfloor.

*Previously known as CDM-MONT
-
Extreme Performance
Uses elastomeric isolators with low stiffness and high resilience, achieving a natural frequency of ≥ 6 Hz or springs achieving a natural frequency of ≥ 2.5 Hz.
-
Jack-up System
The isolated slab is raised off the structure to the required void depth once the concrete has cured.
-
Replaceable & Inspectable
Uses isolators that remain accessible, inspectable and replaceable during installation phase or even after installation and concrete pour.
-
Low Risk of Acoustical Bridging
Provides the least amount of contact points reducing the potential for acoustical bridging.
