Floor Drainage - Design Considerations
PIPEWORK
MATERIALS AND APPEARANCE
The type and size of pipework in an
installation is fundamental to the
correct selection of gullies. Frost
drainage gullies can be connected to
all pipework in general use.
Strength, corrosion resistance
and appearance are important
considerations when making drainage
selections
Finished 昀氀oor areas
Gullies with attractive gratings or
covers made of satin nickel bronze,
polished nickel bronze or stainless
steel are for use in areas where they
contribute to the aesthetic appeal of
an area.
Un昀椀nished 昀氀oor areas
Ductile iron gratings, whilst extremely
durable and visually acceptable
are best suited in un昀椀nished and/
or industrial settings such as service
areas or for restoration projects to
match period architecture.
FLOOR AND FLOORING
Floor construction type has a direct
in昀氀uence upon appropriate drainage
selection and so should be established
at the outset.
The depth of the structural slab and
available space will in昀氀uence the
selection of gullies, while selection
of an extension may be necessary to
bring the grating or cover to 昀椀nished
昀氀oor level.
Installations with a drainage
membrane will normally require
the use of gullies with a membrane
clamping collar.
Drains located in pedestrian surfaces
or access routes must be disabled
compliant.
Di昀昀erent kinds of 昀氀oor 昀椀nishes, such
as concrete, epoxy resin, ceramic tiles
or sheet vinyl will in昀氀uence the type of
grating or cover to be selected.
