Advantages of Precast:
• Wall panels are constructed off-site regardless of weather
conditions ard are rapidly assembled on site.
• As a result projects are completed sooner, leading to earlier
occupancy and faster revenue returns.
• Precast concrete has unsurpassed fire ratings, readily
achieving up to 4 hours fire resistance.
• Concrete will not burn or give off lethal fumes, and will retain
its structural integrity for safe evacuation and fire fighting.
• In real fire situations, in temperatures above 1100°C,
concrete has retained its structural stability even in complete
burn out situations.
• Because it is impervious to wet and dry rot, the structure will
not weaken over time.
• The density of the concrete provides excellent sound
attenuation, thus reducing sound transmission.
• Wall Panels reduce vibration and have fewer joints through
which sound can potentially travel.
• Lower maintenance costs and insurance premiums, together
with greater occupant satisfaction and re-sale value.
