POLYJOINT
CONCRETE FLOOR SLAB EXPANSION JOINT
SYSTEM
INTRODUCTION
Whenever
casting a large horizontal expanse of concrete expansion
jointing is needed particularly where the concrete
interfaces with perimeter walls and concrete columns.
Traditionally soft board has been used for this
application. Soft board, however, has a number of
disadvantages as it swells when in contact with
water, is difficult to cut with precision and deteriorates
and becomes unsightly over time.
Expanded polystyrene however has none of this problems
and thus makes an ideal expansion jointing material.
PRODUCT DESCRIPTION
Polyjoint
is a range of pre-cut sheets of expanded polystyrene
10mm thick x 1,2m long of varying heights - 170mm,
255mm and 340mm to suit different standard slab
depths.
Polyjoint is supplied in standard packs of 122
meters.
SYSTEM APPLICATION
Based
on slab depth and size of slab to be cast pre-determine
quantity and size of Polyjoint required.
Place Polyjoint where required and if needed to
be held in place before casting the slab use an
EPS adhesive to glue the Polyjoint to the supporting
wall.
Around column bases wrap the Polyjoint around the
column and hold it in place with masking tape.
Pour concrete.
PRODUCT BENEFITS
Supplied
pre-cut Polyjoint is supplied precut to the slab
depth to be cast so no cutting is required on site.
Dimensionally
stable
Expanded polystyrene does not expand or deteriorate
when wet so no excessive jointing compounds are
needed to seal expansion joints.
Easily cut
Polyjoint can be readily cut with a knife or hand
saw to fit the exact dimensions of the slab to be
cast.
Long lasting
Polyjoint will not deteriorate over time leading
to unsightly gaps in the concrete.
Lightweight
Packs of Polyjoint are lightweight and easy to transport
around sites
Easy to fix
The Polyjoint panels can be glued in place with
an expanded polystyrene adhesive or taped around
columns to hold them in place prior to pouring the
concrete.
