How we Help
Natürliches Bauen begleiten – vom Konzept bis zur Fertigstellung Jedes Projekt ist anders. Ein Architekt entdeckt Hanfkalk vielleicht zum ersten Mal, ein Bauunternehmer sucht das passende System für eine bestimmte Anwendung, oder ein Bauherr möchte einfach verstehen, welche Möglichkeiten für sein Projekt bestehen.

Why Build with HempLime
Das Material, die Systeme und die Möglichkeiten verstehen. Die Entscheidung für Hanfkalk sollte jedoch kein Trend sein. Es geht darum, das Material zu verstehen, seine geeigneten Einsatzbereiche zu kennen und die passende Bauweise und das richtige System für das jeweilige Projekt zu wählen.
Why It's the Future of Building
In a world where sustainability is no longer optional but essential, HempLime—also known as hempcrete—is emerging as a revolutionary building material. Combining the woody core of the hemp plant (shiv) with a natural lime-based binder, this lightweight, breathable, and 100% natural material is transforming the way we think about construction.
What Is HempLime?
HempLime is a bio-composite made from:
- Hemp shiv (the inner woody part of the hemp stalk)
- Lime-based binder such as hydrated lime with mineral additives or NHL 5 (Natural Hydraulic Lime)
- Water
When mixed together, this blend creates a natural insulating material that’s cast in place, often within formwork to build monolithic walls. The result? Solid, breathable, and carbon-storing walls that regulate indoor temperature and humidity.
Why HempLime is the Future
✅ Carbon negative: The lime binder continues to absorb CO₂ as it cures. This means your home is storing carbon, not releasing it.
✅ Healthy Indoor Air: HempLime walls are vapor-permeable, mold-resistant, and regulate humidity naturally—ideal for anyone sensitive to pollutants or toxins.
✅ Thermal & Acoustic Insulation: Say goodbye to synthetic insulation. HempLime keeps your space warm in winter, cool in summer, and quiet all year round.
✅ Fire and Pest Resistant: The lime component is naturally fire-retardant and prevents insects and rodents from nesting in the walls.
✅ Durable, Yet Recyclable: Unlike concrete, HempLime can be crushed and reused at the end of a building's life, making it a truly circular material.
