Litecrete is a revolutionary lightweight precast concrete system manufactured by Wilco Precast Ltd, established in Auckland in 1962. Litecrete uses pumice as an aggregate, which dramatically reduces the weight of the concrete. The air cells in the pumice provide superb insulating properties, convenient lightness. The combination of pumice and cement, together with steel reinforcing systems and polypropylene fibre, gives Litecrete its unique strength-to-weight ratio. Litecrete products are ½ the weight of normal precast concrete and can be used in both residential and commercial construction. 150 mm thick panels can be manufactured up to 7 metres x 3 metres. Litecrete is a friend of the environment in all stages of its life span, making it a natural choice for sustainable home construction. The predominant raw material for the cement in Litecrete is limestone, the most abundant mineral on earth. The pumice aggregate is available locally in huge quantities. Litecrete structures will n
