Description

Stravifloor Jackup-E is an isolated floating floor system using moulded natural rubber within bell-shaped cast iron housings 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.


Stravifloor Jackup-E boxes allow for easy adjustment of the final floor height. It is cost-effective solution with minimal risk of acoustic bridging between the floating floor slab and the subfloor.


Features and benefits:

  • Can be provided with elastomer bearings giving a natural frequency as low as 9 Hz.
  • Standard solutions available with moulded natural rubber resilient pads in two standard grades: Pad-L (low stiffness), Pad-M (medium stiffness)
  • Standard design is for 85 mm thick floors (box height). The housing can be fitted with a height extension unit for thicker floating floors.
  • Stravifloor Jackup-E boxes have a maximum load per box of 49 kN.
  • Reduces the risk of having a bridge between the slab and the structure, isolation is guaranteed because the whole slab is lifted (there is no opportunity for any debris to be left in the cavity and any bridging is broken when the slab is lifted up).
  • Can have a shallow or adjustable air void.
  • Can take high loads before the slab is raised (e.g. used as a storage area during construction).
  • Eliminates the cost and need for combustible, rot-prone plywood forms.

Specification data - Spring isolators

Spring isolators type

Closed - Elastomer bearings.

Guidance for specification option:

Can be provided with elastomer bearings giving a natural frequency as low as 9 Hz.

Colour code

Black.

Load

Load capacity of each box: 49 kN.

Isolator

Pad-M.

Box size

Bespoke.

Guidance for specification option:

  • Standard design is for 85 mm thick floors.
  • The housing can be fitted with a height extension unit for thicker floating floors.
  • Insert requirements.

Standards

Acoustic test standard: Rw measured in accordance with ISO 10140-2:2021 and single figure ratings determined in accordance with EN ISO 717-1:2021. Ln,w and ∆Lw measured in accordance with ISO 10140-3:2021 and single figure ratings determined in accordance with EN ISO 717-2:2021.

Weighted sound reduction index, Rw

71 dB.

Manufacturer guidance

Consult manufacturer's literature and/or Stravi-dB (stravi-db.com) for detailed sound reduction index values.

Impact sound reduction

ΔLw: 36 dB.

Manufacturer guidance

Consult manufacturer's literature and/or Stravi-dB (stravi-db.com) for detailed sound reduction index values.

System height

Minimum system height: 105 mm.

Air gap

20 mm (minimum).

Manufacturer guidance

50 mm is the most common air gap.

Maximum air void limited by bolt buckling resistance.

Floor finish

Specified separately.

Guidance for specification option:

Compatible with all floor coverings, including impact absorption layers to be used on gyms free weight areas, under the floor coverings, to improve the structure-borne noise mitigation through extending the time of contact/impact and, thereby, reduce the peak impact force and the noise generated.

Weight

2.12 kN/m².

Guidance for specification option:

If installed with normal weight reinforced concrete slab, 85 mm thick.
