What is Hempcrete Made Of?

Hempcrete blocks are a game-changer for sustainable residential construction. Designed to integrate seamlessly with Australian standard timber or steel frames, these blocks can be installed as external cladding or internal walls. They offer a versatile and natural solution for your new home or renovation, and they’re as strong in performance as they are light on the planet.

Forget traditional materials that trap moisture, overheat your space, or contribute to your carbon footprint. Hempcrete steps in with a refreshing, modern alternative that makes sense for Australia’s climate, lifestyle, and growing demand for eco-friendly housing.

What Is Hempcrete Made of at Respirabuilt?

Let’s talk about the hempcrete recipe behind our blocks.

Not all hemp-based building materials are created equal. At Respirabuilt, we take pride in doing things the way they should be. We only use hemp products that are 100% natural, cement-free, and sustainably sourced. Nothing sneaky or synthetic here.

Our hempcrete is crafted from premium hemp shivs combined with a lime-based binder. This mix allows the walls to breathe, keeping your indoor spaces dry and comfortable. No mould, no trapped heat, no weird odours. Just strong, clean materials doing their job flawlessly.

So what exactly goes into our hempcrete?

• Hemp shiv – the woody core of the hemp stalk. It’s lightweight, absorbent, and holds air, making it perfect for insulation.

• Lime binder – a natural, mineral-based substance that binds the hemp together. It hardens over time and continues to absorb carbon dioxide even after installation.

• Water – just enough to activate the binder and help with curing.

That’s it. No cement, no fillers, no compromises.

We partner with a trusted supply chain and local manufacturers to ensure quality from start to finish. Every batch is consistent, reliable, and fully traceable. You’ll know exactly what’s in your walls, and what’s not. And because our materials are free from toxins and chemicals, you get healthier living spaces that are safer for your family and better for the planet.

This is hempcrete done right.

What Makes Respirabuilt Different?

At RespiraBuilt, we do way more than just sell blocks. We build  a better way to live.

We specialise in innovative hempcrete solutions that create healthier, more sustainable homes. Our blocks offer superior insulation and energy efficiency while reducing your carbon footprint. In fact, our products are carbon-negative, which means they lock away more CO2 than they release.

We don’t believe in one-size-fits-all. Whether you’re planning a bush retreat, a suburban home, or an inner-city reno, we’ll guide you on how to make the most of hempcrete. 

We also care about building performance over the long haul. Hempcrete doesn’t just tick a few eco boxes; it truly performs. It’s breathable, fire-resistant, non-toxic, and able to buffer heat, cold, and humidity. That means more comfort inside, less reliance on heating and cooling, and lower energy bills. Over time, the savings add up, and the comfort speaks for itself.

This isn’t just the future of construction. It’s the smarter way to build right now.

Hemp blocks are a surprisingly flexible solution for almost any building project. Whether you’re working on a new build or retrofitting an old structure, they offer serious value.

Here’s what makes them a standout choice:

Mould Resistant
Hempcrete helps stop black mould in its tracks by naturally regulating humidity. Say goodbye to headaches, itchy skin, and those mystery sniffles. It’s hypoallergenic, toxin-free, and a lifesaver for indoor air quality.

Acoustic Insulation
Sick of hearing everything the neighbours say? Hempcrete has your back. Its porous structure soaks up sound, giving you privacy and quiet without resorting to heavy, synthetic materials.

Pest Resistant
Thanks to its lime content, hempcrete is naturally unappealing to termites and rodents. It doesn’t rot, and it doesn’t taste good to them. That means you won’t need chemical treatments to keep critters out.

Carbon Negative
Hemp is a pro when it comes to absorbing CO2. It soaks up carbon while it grows, and the lime binder continues absorbing CO2 even after construction. The result? A building material that gives back to the environment.

Improve Energy Efficiency
With insulation values that outshine other common materials like Hebel, hempcrete helps slash your heating and cooling costs by up to 70 percent. That’s less strain on your wallet and your air conditioning unit.
