Lightweight Concrete NZ

Hebel is a lightweight autoclaved aerated concrete building material which is factory cut into blocks, panels, and special elements for a wide variety of building applications, both load bearing and non-load bearing. Hebel offers an impressive range of features and benefits which make it not only economical and pleasing to the eye, but an excellent choice as a sustainable building material .
Manufactured from sand, cement, recycled material, lime, gypsum and an aerating agent, it is moulded, cut and steam pressure cured in an autoclave before being packed, ready for transport. Hebel autoclaved aerated concrete is actually hydrated calcium silicate (C5S6H5) known as Tobermorite, which is a naturally occuring crystaline material found around the world. It is this crystaline structure which provides Hebel with its strength and stability. Tobermorite Crystal
The Hebel story began in the early 1940's when Josef Hebel began manufacturing autoclaved aerated concrete in Germany in an attempt to produce a more cost effective construction material using industrial by products. After World War 2, much of post-war Germany was rebuilt with Hebel AAC products as architects and builders began to realise the advantages of this strong lightweight material.
Hebel's German success led to the expansion of Hebel into the worldwide market, where today it is manufactured and sold in over 30 countries worldwide. With the expertise and quality associated with the Hebel brand that has been aquired over decades, Hebel building systems have established themselves and proved their worth
