Gutter Designed to Approved Document L
Stepped, Laid to Falls, and Tapered Gutters
Many existing timber boxed and felt or lead
lined gutters are built to falls and some are also
tapered on plan. Many terminate in a sump at
the outlet.
The Unifold Gutter Lining System can faithfully replicate these conditions,
sometimes providing an improvement in
performance and capacity.
Due to its unique hinge principle it is possible,
when conditions allow, with the strategic
placement of hinges in a parallel length of
Unifold, for the system to replicate either
tapered on plan or laid to falls conditions or
both.
Stepped lead gutters are always built to falls
and some are also tapered on plan.
The Unifold Gutter Linig System can replicate these gutters but unlike
these systems Unifold is fully sealed on
installation. Each "step" is provided as a
factory manufactured fabrication and the
Unifold lengths are joined to these.
Unifold creates virtually identical conditions to
the existing gutter but with greater security.

Creation of Falls
When it is desirable and where conditions allow,
it is possible to introduce falls to an existing laid
level gutter to remove standing water caused by
deflections in the existing gutter or to improve
the discharge speed of the installation. This is
achieved with the use of cut to falls insulation
with Unifold laid over.
Falls are created from stop-ends to outlets and
between outlets and always terminate in a sump
arrangement at the outlet.
The apex of the falls condition is an ideal position
for an expansion joint should it be required.
Feasibility
When the creation of falls conditions are
contemplated then the installation should be
the subject of a feasibility appraisal by Ampteam Technical department.
Survey
AMPTEAM personnel undertake a full survey
and design following placement of an order.
NB: Any fall less than 1:300 should be
considered level and any installation that
cannot achieve 1:200, as a minimum should
be carefully considered
