Description

Litecrete precast residential wall panels have been designed to offer a durable alternative to traditional house construction methods.

Litecrete precast panels form an integral wall — solid, continuous and airtight. Litecrete is manufactured using pumice as an aggregate, which reduces the weight of the concrete yet achieves strength of 12 MPa. The air cells in the pumice provide excellent insulating properties.

Key Features

Litecrete is manufactured under strict quality-controlled factory conditions, delivered to site and rapidly installed.
Various thicknesses can be manufactured to order, from a minimum of 150mm.
Panels have fully embedded steel reinforcing.
Panels for a typical house could be installed in one or two days.
Installation unaffected by adverse weather.
Safer environment; Litecrete is fire resistant, non-toxic, mould and mildew resistant.
Exterior finishes to suit; fine or accented plaster; smooth or textured paint systems or natural concrete finish.
Built-in insulation provided by the pumice aggregate ensures energy savings; warm in winter, cool in summer.

Scope of Use

Standard sized panels up to 7-8 metres x 3.5 metres and can be used for single-storey or two-storey applications. Larger panels are possible subject to freight/design parameters.

All Litecrete applications are subject to specific engineering design by a registered structural engineer (not by Litecrete) prior to lodging a Building Consent application.

To comply with the Building Code insulation requirements for Solid Construction, in Climate Zone 1, the required panel thickness is 220 mm.

In-Service History

Litecrete (NZ) Ltd is a wholly owned subsidiary of Wilco Precast Ltd, Papakura, a premier precast concrete manufacturer, which has been manufacturing precast concrete for over 50 years.

Other Performance Attributes

Litecrete has proven to have a superior initial and secondary water absorption rate compared to 30 MPa normal precast concrete.
Litecrete 3000 x 1200 x 220mm thick panels achieve 640 bu’s (University of Auckland Inplane Test report).
Can offer cast-in surface textures and rebates similar to standard precast concrete. These can range from simple diagonal and vertical lines up to intricate patterns using rubber formliners. Rough-sawn timber textures are currently in vogue, however there is panel width limitations due to the extra suction experienced when de-moulding the panels off the timber planks.
