9 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.
