By dropping the in-situ concrete over the walls to provide continuous bearing.

By adjusting beam locations so that penetrations fall within the infill zone.

Ultrafloor can be cantilevered.
The beam ends are generally propped during construction. The maximum span of the cantilever is dependent on the type of system used, the applied loads and the slab backspan.

Ultrafloor generally only supplies steelwork which supports Ultrafloor and is located within the depth of the system. The quote that is received by the Client will stipulate what steel will be designed and supplied by Ultrafloor.

There are three methods available:

1. Beams can be locally set down which is accommodated in the support structure.
2. Extra topping can be added to the slab in areas outside the required set down zone.
3. Standard topping could be reduced in the set down area up to 20mm.
4. A mix of Ultrafloor beam sizes can be used for, i.e. 150R’s in the setdowns and 200R’s elsewhere.

A line of props must be located to support Ultrafloor during construction where indicated on the Ultrafloor drawings. For a single slab level they should remain in place for a minimum of seven days after the topping slab is poured. The Technical Department must be contacted if props are required to be removed prior to seven days, or if the slab is to be used to carry substantial stacking loads or additional slab levels.

The following requirements are generally necessary:

1. Additional topping over beams to achieve cover requirements to reinforcement.
2. A larger mesh should be used to provide a higher degree of crack control.
3. The strength of the concrete used on the topping slab generally increases.
4. Falls within the topping are required for drainage.
5. A flexible waterproof membrane should be applied.

Ultrafloor can be used in roof applications.

The insulation, waterproofing and use of slip joints at external walls should always be considered.

SL72 mesh is used as a minimum in all systems. Larger mesh sizes may be required dependent on the degree of crack control required by the client. In interior cases with standard topping, the SL72 mesh will provide a minor degree of cracking.

Please contact the installer whose name should appear on the Document Transmittal form received with Ultrafloor Installation drawings. Alternatively contact the Sales Representative for your area.

Ultrafloor does not recommend the use of these connection systems as concrete could spall affecting the capacity of the beams.

Ultrafloor can be cantilevered.

The end of the beams are generally propped during construction. The maximum span of the cantilever is dependent on the type of system used, the applied loads and the slab backspan.

Beams should generally not be cored without first contacting the Ultrafloor Technical Department for advice. It is possible to add extra beams into the design so that future penetrations can be cored as required (must be requested early, i.e. prior to quotation). For larger penetrations seel saddles should be utilised and incorporated into the design.

All reinforcement which is utilised by Ultrafloor to achieve the structural adequacy of the system would normally be designed by Ultrafloor. All other reinforcement should be designed by the Engineer on the project.

The fire rating for the general Ultrafloor slab system is 2 hours.

The amount of lead time is generally related to the size of the project. For a standard residential project a three day turnaround would be a minimum requirement.

An approximate cost over and above the Ultrafloor component of the suspended floor would be $50/sq m. However this may fluctuate depending on which floor system is installed, what rate you pay for concrete, etc, etc.
