Litecrete builds on traditional pre-cast concrete advantages by offering a lightweight alternative in the form of load-bearing exterior and interior walls, firewalls, acoustic walls, vertical façade fins, and exterior cladding panels.
The precast panels form an integral wall — solid, continuous and airtight. The pumice aggregate and the induced air entrainment in the cement matrix dramatically reduces the weight of the concrete yet achieves 12 MPa strength.
Litecrete is manufactured under strict quality-controlled factory conditions.
Standard sized panels up to 7-8 metres x 3.5 metres, subject to freight considerations and design parameters such as window or door opening sizes.
Litecrete will typically reduce the deadload on the structure by 50% compared to standard precast concrete.
Litecrete can give perceptive designers an edge in a very competitive market.
Litecrete is competitively priced with similar building materials.
Commercial panel sizes are tailored to suit the project.
The design, application, engineering, panel sizes and installation requirements for low-rise and high-rise Litecrete commercial projects differ markedly from residential installations. Potential uses are exterior cladding, sunshades, fins, acoustic or firewalls and façade re-instatements.
All Litecrete applications are subject to specific engineering design by a registered structural engineer (not by Litecrete) prior to lodging a Building Consent application.

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 are panel width limitations due to the extra suction experienced when de-moulding the panels off the timber planks.
