    FIND OUT THE BENFITS OF PRECAST CONCRETE CONSTRUCTION.

Precast concrete delivers superior construction outcomes.

We have been building with reinforced precast concrete since the 1970s. We have seen our constructions last over decades - requiring modernisation before reconstruction of any nature. Based in the Wellington region we are known as 'leaders in precast concrete construction'.

However, the main benefits of constructing with precast concrete are in the properties of the concrete itself. A reinforced precast concrete structure offers hundreds of unique advantages for owners, architects, engineers and developers. Many of these advantages serve and extend the useful life of the building - but in fact, the health-giving properties of mould resistance and the livability aspects such as superior noise barrier effect are what makes the construction with concrete relatively popular.

Concrete buildings are superior in many ways. With light commercial or multi-residential construction projects that may be close to or right on main roads and highways, the benefits of a superior sound barrier and relatively low cost of maintenance, along with the energy efficient properties of concrete, allowing lower running costs as an added benefit and of course the huge safety consideration of concrete adding a firewall effect - the use of precast concrete for this type of construction project is a no-brainer.

What are the main benefits of building with precast concrete? Read on...

Sq 1
Effective Noise Barrier

Concrete walls, floors and stairs inherently exceed sound regulations eliminating the need for additional sound attenuation and offer very high acoustic privacy. This is an immense advantage in apartments, office complexes and rest homes where reduced noise levels maximise occupant satisfaction. The high density of concrete used in the walls of commercial buildings resists the transmission of noise by as much as two-thirds. Concrete is hugely effective at reducing low-frequency sounds that make less rigid walls vibrate, rendering the transfer of most noise virtually inaudible.

Natural Fire Walls

Architectural precast concrete is non-combustible with inherent fire-resistant capability, creating a safe envelope that helps protect personnel, equipment and the building itself. Concrete walls provide excellent resistance to fire and heat and effectively inhibit the spread of smoke and flame, while also retaining their structural integrity. That in turn reduces insurance rates. The code requires 60 minute fire rating generally between intermediacy walls. Our precast concrete walls are a ‘natural fire wall’ with 180 min fire rating - which eliminates the need and cost of additional fireproofing measures.

Strong, Durable and
Exceeds Earthquake Standards

Faced with the force of nature - sever weather conditions, earthquakes, fire and floods - few building materials can match this robust, durable substance. You can rely on the structural integrity of concrete for your lasting investment. Reinforced concrete floors are tied into 50 mpa reinforced precast walls that will defy the strongest of earthquakes. As the Canterbury earthquakes proved, suitably designed and built concrete structures performed admirably, helping to preserve and minimise damage (read more on CCANZ website). All Homestead structures are specifically engineered to exceed the required earthquake standards for council consent.

Aesthetics and Design Flexibility

Architectural precast concrete provides the designer with an unlimited architectural vocabulary of expression. Whether the aesthetic intent is traditional or contemporary, precast concrete can be shaped in a cost effective manner. The material is incredibly responsive to the designer’s needs. The only limits are imagination and creativity. The ability to manipulate colour, texture and form make precast concrete an excellent material choice. It can be formed into any shape, providing an unlimited imagination of curves and angles. There is infinite potential for development and manipulation of the size, shape, colour, texture and details of your building. No other material offers such amazing design versatility as concrete.

Initial Cost

Faster completion times on high-rise projects reduces interim financing costs, results in earlier cash flows, and produces other economic benefits. This ultimately lowers the building’s long-term overall costs and makes the use of precast concrete more economical than any other facade materials, and moves a projects’ revenue stream forward. The speed of building erection and its ability to be cast and erected in all kinds of weather aids the entire construction. Units can be produced as soon as drawings are approved, ensuring units are ready for erection as soon as foundation work and other site preparation is completed. These advantages allow the building’s shell, to be enclosed quickly. In turn, letting interior trades to begin work earlier and reduces overall construction time.

Sq6
Reduced Maintenance

On-going maintenance is central to the viability of any commercial building. The beauty of your concrete building is that they still look new years after construction. There are actually no maintenance requirements to the structure. The concrete walls are not vulnerable to rot, rust, settlement or deterioration as in other building materials and in turn, offer higher re-sale value.

Sq7
Better Energy Efficiency

Precast concrete panels are designed to provide a high degree of energy efficiency for the buildings they enclose. This provides economies in the cost of the air-conditioning system by reducing the thermal load. The thermal mass inertia of concrete, which is recognised in NZ standards, reduces peak heating and cooling loads, thus saving energy year-round by reducing large daily temperature swings. This means, that with the same insulation, a concrete building stays warmer in the winter and cooler in the summer than conventional construction. Also concrete forms an integral wall system - solid, continuous and air tight reducing draughts and energy loss.

Environmental Impact

Concrete is the ‘Natural Choice’. Because precast concrete is made of air, water, cement, sand and gravel, you can rest assured that the construction of your building will use some of the most plentiful resources on the planet! Precast concrete is an environmentally sound material. It is produced from natural materials. No toxic substances are produced in its production or use. Also, the production energy consumption of the concrete is quite small. Our concrete structures are long lasting and durable, going a long way towards waste reduction.

Healthy and Safe Environment

Concrete provides a healthier environment by minimising exposure to mould, mildew and other indoor toxins. Solid concrete walls are more air and water tight than other construction methods reducing drafts, cold spots and risk of a leaky building.

Life Cycle Costs

When comparing the cost of alternative facade systems, the cost throughout the design life of the building needs to be evaluated. A precast facade can be designed to match the intended life of the building with minimal maintenance, providing substantial long-term savings. Precast concrete panels present a durable aesthetically pleasing exterior surface that is virtually air and watertight and does not require painting. This helps the building remain in first class condition long after the mortgage is repaid, ensuring its desirability to future tenants or owners. It also means attractive refinancing can be accomplished more advantageously too.

The decision to build with reinforced precast concrete is a smart, value-based decision.
It’s a solid choice with huge benefits.
