Precast concrete is produced by casting concrete in a reusable mould or form, and is widely popular throughout NZ’s construction industry – allowing design versatility and minimal maintenance.
There are benefits of using precast concrete components, including:
Quality and durability
Dimensional accuracy and tight tolerances
Speed of construction
Reduction of onsite activity, noise, and disturbance
Reduction of onsite waste
Large spans available from prestressing
Precast concrete solutions
A variety of surface finishes are available to suit your precast needs:
Textured and patterned surfaces enhance the environment.
Formliners, polishing, chemically treating, painting or other special coatings are available as surface treatments for appearance, environmental or durability of precast cement products.
Production
Factory-produced precast is manufactured to tighter tolerances by experienced workers, using quality procedures and customised concrete mixes
Precast factories are experienced at handling a range of concretes. They’re able to ensure that necessary compaction, finishing and curing is achieved. Manufactured under controlled conditions in a special purpose facility, precast concrete is highly customised for each client.
Agricultural products
Precast concrete products can withstand the most extreme weather conditions and will hold up for many decades of constant usage. This makes precast the perfect solution for agricultural structures.
Precast concrete products are commonly used in water troughs, feed troughs, culverts, effluent bunkers, feed pads and walls, stock stops, under passes and Y panels.
Buildings
It’s common to employ precast concrete building components in architectural and structural capacities at the same time.
Precast concrete building components are commonly used in structural applications including foundations, beams, floors, walls and architectural applications including cladding.
Prestressed or structural products
Prestressing is a technique used to:
Introduce stresses into a structural member: improving and enhancing it’s behavior.
Introduce compression: into regions where tension stresses will be created by applied loads.
This technique is used to make concrete beams, columns, single and double tees, wall panels, and hollow core slabs.
Water and wastewater products
Water management structures are designed for underground installation and specifically engineered for their environment. These precast concrete products include septic tanks, cesspits, pipes, manholes and rainwater tanks.
Many of them are modular in design and are available in a number of configurations. The structures are all connected and constructed with watertight integrity, so the contents discharge only through the proper outlet.
Transportation products
Precast concrete transportation products are used in the construction, safety and site protection of our road and railway transportation systems. They include railway sleepers, bridge super tees, segmental bridge units, tunnel segments, sound walls and barriers.
Golden Bay for precast products
All our cement products are are suitable fit for precast concrete solutions. Find out what’s the most appropriate for your project:
EverSure Type GP: is a diverse cement suitable for precast concrete products. However, if you need a higher-strength product for demoulding or releasing prestressing strands, we recommended to use EverFast Type HE.
Microsilica SF: improve concrete strength and durability through a pozzolanic reaction that creates additional calcium silicate hydrates – providing an improvement in bond at the concrete reinforcement interface.
EverPlus Class C Fly Ash: improves long term concrete strength and durability through the same process as Microsilica SF. EverPlus Class C Fly Ash offers optimal benefits through its spherical particle shape, and will assist with concretes that are extruded or manufactured dry to aid compaction.
A ternary blend of EverSure Type GP or EverFast Type HE, Microsilica SF and EverPlus Class C Fly Ash: from our product solution range can be supplied for your specific durability requirements.
