Stravifloor Jackup-R* is an isolated floating floor system using reinforced steel boxes cast into concrete and jacked up after the concrete has cured, to provide the required void depth. 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-R boxes allow for easy adjustment of the final floor height as well as replacement or inspection of isolators, should the use of the room or load conditions change in the future.
Stravifloor Jackup-R 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.
Available with either spring bearings or natural rubber pads
This bulletin, which summarizes the key-findings of an extensive test campaign studying the acoustical performance (airborne sound reduction and impact noise isolation) of our redesigned Stravifloor Jackup-R system serves as a guide to those designing and prescribing jack-up floating floors.
