Supercrete Structural Floor Panels can be cantilevered,
providing the cantilevered length does not exceed one
third of the panel length, but with a maximum of 1.2
metres for 200mm thick panels or greater, and 900mm for
150 and 175mm thick panels, see Detail SFP 2-6 above.
Cantilevering of panels that require a concentrated load on
the outer end (e.g. a solid masonry balustrade) should not
be considered and concentrated loads along the outside
longitudinal edge of panels is also not allowable. Load
conditions on cantilevered panels need to be checked by
the project engineer, to ensure that there is not an uplift
problem at the opposite end of the panel to the cantilever.
2.1.6 Support of Panels
2.1.6.1 Supercrete Block Supports
Where the end, or sides, of Supercrete Structural Floor
Panels are supported on Supercrete Block walls, there
are a number of configurations that the panel support,
bond beam and floor ring anchor may take. These

are shown in Figure 1, page 23 and these bond beam
types should be referred to by number when preparing
construction plans.
Type 5 can be used where the ring anchor is also used as
the bond beam to stiffen the top of the wall.
However, if this option is adopted, the block walls should
be propped at the time of placing the floor panels, as they
may have insufficient resistance to any lateral forces that
might be imposed on them during the installation of the
panels. These props should remain in place until the ring
anchor/bond beam is poured and cured. Types 2, 7 and 9
have cured bond beams prior to panel placement and are
therefore more rigid and do not require propping.
The vertical reinforcing in the block walls (normally M12
threaded rod) are cast into the ring anchor and bond beam,
and these transfer the lateral forces from a floor diaphragm
into the block bracing walls and hence to the foundations.
