Hollowcore
Advantages of Using Hollowcore Planks Flexibility and Design
Precast floors can generally span
greater distances than timber, providing the designer with
more options. Any alterations to the floor layout can be accommodated
by the homeowner at a later stage, without the need of any
further structural works to the floor.
Separating Floors
Hollowcore floors hold a robust detail relating
to Approved Document Part E ‘Resistance to the Passage
of Sound’ and can therefore be used without the need
to carry out pre-completion site tests.
Upper Floors in Houses
Noise at home is a major source of concern
to occupants. Concrete upper floors provide improved sound
insulation between floors - essential for households with families.
Also block partition walls can be supported on precast floors,
further improving sound insulation between rooms.
Easy Installation
Installation of the Hollowcore floor planks
is straightforward. The units are hoisted into position on
the supporting structure by crane and the joints grouted
with 20 N/mm2 concrete using a maximum 10 mm aggregate to form a
monolithic floor. Longley Concrete Floors provide a complete
professional service and employ their own trained/experienced
fixing teams to install the precast concrete products, operating
on a national basis. Risk Assessments and Safe Working Method
Statements are carried out by a Contracting Team.
Immediate
Working Platform
The completed floor provides an
immediate working platform for follow on trades. This reduces
site delays to a minimum.
Eco-Friendly
Masonry homes with concrete
floors are energy efficient and their mass helps to balance
internal temperatures, thus avoiding the need for air conditioning
which can be noisy and harmful to the environment.
Fire Resistant
The
safety of you and your family are paramount should a fire start.
Traditional masonry construction including concrete floors
gives four times longer to exit, ie 2 hours protection against
30 minutes for timber. Concrete is inherently fireproof with
no need for anti-fire chemical treatment and its thermal capacity
absorbs heat from the fire, thus cooling it reducing the rate
of spread from ignition to full fire.
Squeak Resistant
Due to
the density of concrete and its limited deflection,
concrete
floors inherently do not cause sound transmission
when walked
on.
Pest Resistant
Concrete products are completely resistant
to vermin, rot and termites. It is inorganic and of no nutritional
interest to pests thus the structure will remain intact for
the life of the building.
Flood Resistant
It is becoming more
common to build on flood planes due to the lack of land.
In
the event of flash floods, concrete floors dry out easily and
quickly
and remain in place.
