The pros and cons of Hebel.

The use of Hebel in residential construction sparks enthusiasm and debate among Australia’s builders.The light weight autoclaved aerated concrete promises numerous construction benefits, yet its environmental footprint raises important questions.

For those seeking construction site eco-waste management, understanding Hebel’s pros and cons will help you decide if it’s the right choice for your next project. Let’s break down Hebel’s benefits for construction and the challenges it presents in waste disposal.

What is Hebel?

Hebel is an Autoclaved Aerated Concrete (AAC) construction product consisting of natural raw materials including sand, cement, lime, gypsum and aluminium powder, combined with water and an expanding agent. This mixture is manufactured into a slurry that rises like bread dough, resulting in a lightweight, multipurpose construction product.

Hebel is used for internal and external construction, floor systems and facade treatments, and its features include:

• Enhanced strength thanks to anti-corrosion steel reinforcement 
• Available in panel and block forms for versatile applications
• Provides four times the thermal insulation of standard concrete
• Contains air pockets that enhance insulation performance
• Excellent fire resistance, particularly valuable in bushfire-prone areas
• Superior sound insulation capabilities
• Strong moisture control properties.

The fact it’s lightweight also means less labour for faster installation and can easily be carved, sculpted or cut to size.

Environmental considerations of Hebel waste

The manufacturing process of Hebel carries a considerable carbon footprint, making responsible waste removal even more important. Despite its advantages, unlike other construction materials, Hebel’s composition presents specific challenges in the waste stream, requiring careful handling and segregation to maximise recycling potential.

Construction site supervisors must establish dedicated collection areas where Hebel waste can be separated from other construction materials, because contaminated Hebel waste becomes significantly more difficult to process and if so, will end up in landfill rather than being recycled.

Why?

• Hebel composition also comprises steel, adhesives and renders 
• Autoclaved aerated concrete’s distinct qualities prevent its simple crushing and reuse, unlike traditional concrete
• Exposure to weather or foreign materials degrades Hebel’s cellular structure, impacting its processability.

Like any contaminated waste, Hebel waste sent to landfill means losing the chance to repurpose the material, it can also impact soil composition and groundwater. This is why it’s vital that site teams are thoroughly trained in identifying and properly handling Hebel waste to avoid contamination.

Recycled Hebel uses

Hebel is often promoted as recyclable, but the reality of repurposing it is more complex as you can see. While Hebel offers excellent building properties, its end-of-life management requires careful consideration. When properly processed, recycled Hebel can serve in a few construction-related applications such as:

Base materials

• Can be crushed and used as a sub-base material for temporary access roads on construction sites
• May be incorporated as aggregate in non-structural concrete applications

Landscaping

• Processed Hebel can be used for drainage improvement in landscaping projects
• Suitable for creating temporary construction pathways

Due to Hebel’s complex recycling, prioritising waste reduction via precise cutting and planning throughout construction is the most environmentally sound strategy.
