Precast
Concrete
The development of concrete precasting
techniques in this country has allowed reinforced concrete
to compete favourably with other forms of construction.
Curiously it has not made a serious entry into the residential
construction market until the past 10 years. This later
period has coincided with the development of proprietary
self insulating precast systems.
Concrete precast
methods were pioneered in the US early in the 20th century.
The New Zealand industry is well developed and generally
acknowledged as a world leader. There are good supplies
of the raw materials and technology in most parts of
the country. |

Precasting, whether done in factory conditions
or on site, offers the opportunity to control the quality
to a high standard.
Advantages of precast concrete construction systems include
the following:
- quality control - the quality is better able to be controlled
by casting multiple units in the same mould, by casting
walls flat rather than standing upright and through the
ability to better control environmental conditions.
- lower costs for the reasons noted above
- finishing options inherent in solid concrete construction
- interesting shape and texture possibilities
- speed of construction - with off site production the
panels and other precast elements can be made while the
site is being prepared.
