What we do

Build right,
with what lasts.

Two complementary activities: technical support for your bio-based projects, and direct execution of the works, from advice to spray application.

01

Technical support

We guide you from material selection to results on the wall.

Whether you are an architect, client, self-builder or craftsman looking to expand your range, we work alongside you to structure and secure your bio-based projects, from design to completion.

Every project is different. Our support adapts to your experience level, the nature of the project and locally available materials. The goal is simple: to enable you to achieve quality results, even without prior experience with these techniques.

Bio-based construction & renovation

We spray, insulate, build. With earth, lime and fibre.

Our core business: the mechanised application of bio-based and geo-sourced materials. With our mobile projection unit, we intervene directly on site to carry out high-performance sprayed insulation — hemp-lime, earth-hemp, earth-straw — in renovation as well as new construction.

We are also specialists in earth floors: poured slabs and screeds in earth concrete, a cement-free mix of clay and aggregates, laid over a ventilated rubble base and compatible with underfloor heating. Its mass provides the thermal inertia that lightweight buildings lack, while its hygroscopic capacity regulates indoor humidity.

Beyond projection, we also carry out timber and straw frame structures, compressed earth bricks (BTC) produced on site, and custom metal-wood structures. Every intervention uses local materials and low carbon footprint techniques.

Our approach

What drives every project.

Materials

Local & raw

We work with what the earth gives: lime, hemp, straw, clay. Materials that regulate, that breathe, that don't deplete.

Transmission

Train, not just do

Every intervention is also an opportunity to pass on knowledge. We train teams on site so they are autonomous after we leave.

Rigour

Technique first

Bio-based materials have their requirements. Moisture content, dosages, projection settings: we leave nothing to chance.
