Stravifloor Jackup-R

Replaceable Jack-up Floating Floor System

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.

  • Extreme Performance

    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

    Jack-up System

    The isolated slab is raised off the structure to the required void depth once the concrete has cured.

  • Replaceable & Inspectable

    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

    Low Risk of Acoustical Bridging

    Provides the least amount of contact points reducing the potential for acoustical bridging.

Main Characteristics

  • Available with either spring bearings or natural rubber pads
  • Natural frequency: ≥ 6 Hz (with elastomeric pads) or ≥ 2.5 Hz (with springs) (2'' (50 mm) deflection)
  • Product standard height: 4'' (100 mm), 6'' (150 mm) and 8'' (200 mm)
  • Minimum system height: 4-3/8'' (110 mm) (with elastomeric pads) or 4-3/16'' (105 mm) (with springs)
  • Minimum air gap: 3/4'' (10 mm) (with elastomeric pads) or 3/16'' (5 mm) (with springs)

 

*Previously known as CDM-MONT

Main Benefits

  • Ensures that the floating floor is decoupled from the substrate
  • Replaceable and inspectable
  • Extremely high load capacity allowing for large spans and few support points
  • Can take high loads before the slab is raised (e.g. used as a storage area during construction)
  • Available with springs or elastomers as bearings
  • Solution for passive and active isolation
  • No formwork needed
  • Total build-up height not dependent on thickness of the bearing used, allowing low-profile floating floor systems
  • Easy to install and with small labor cost
  • Adjustable overall void beneath the floating floor
