Hempcrete is a generic term for an old basic recipe of lime, hemp & water that has been used for decades in Europe for the restoration of old wattle & daub or cob construction. A good reference source is "Tom Woolley - Hemp lime construction. A guide to building with hemp lime composites" or "Steve Allin (second edition) - Building with Hemp" for sale at our store for Au $ 40 + postage - please email us. Hempcrete has been used by the Romans and in Japan centuries ago. These structures are still standing! Unlike concrete or masonry, hempcrete does not crack severely under movement. Hence its suitability to be used in earthquake area's. It is also about the seventh of the weight of concrete. Lime is weak under tension and develops micro cracks under movement that seal when moisture comes into contact with free lime. Concrete or masonary will let go suddenly under movement which is why you get big noticeable cracks. |
Only Building code of Australia (BCA) certified Ozhemp Tradical Hempcrete are used, ensuring quality and compliance construction are practice. This provides warranty and guarantee the performance ratings are achieved.
Behind the RenderHEMPCRETE has no equal as a natural building product, sequestering carbon dioxide for the life of the building. Created by simply combining water, hemp aggregate and a lime-based binder it produces a building product with excellent thermal insulating and acoustic properties. The insulation forms the entire wall with the load bearing timber frame fully encased. Hempcrete is not just an insulator - it buffers temperature and humidity, prevents damp and mould growth, making the building a comfortable healthy environment.

Straw Bail Construction
Straw-bale construction is a building method that uses bales of straw (commonly wheat, rice, rye and oats straw) as structural elements, building insulation, or both. This construction method is commonly used in natural building or "brown" construction projects. Research has shown that straw-bale construction is a sustainable method for building, from the standpoint of both materials and energy needed for heating and cooling.[2]
Advantages of straw-bale construction over conventional building systems include the renewable nature of straw, cost, easy availability, naturally fire-retardant and high insulation value

Hebel is Autoclaved Aerated Concrete (AAC)
Hebel has been used in Europe for over 70 years and here in New Zealand for around 20 years. Hebel is Autoclaved Aerated Concrete (AAC) an amazingly innovative building material used for walls, facades and floors.
Hebel is 100% manufactured in Australia by CSR Building Products Limited, from sand, cement, recycled material, lime, gypsum and aerating agents. Hebel is moulded, cut and steam pressure cured in an autoclave before being formed into steel reinforced panels and blocks for a broad range of load bearing and non load-bearing construction applications.
