Works in UHPC
UHPC (ultra-high-performance fibre-reinforced concrete) enables the creation of thin, highly durable components that are coloured throughout. We use it on its own or as a substrate for metal and mosaic.




What we do
- Design of components, joints, chamfers and fixings.
- Coordination with the manufacturer of precast UHPC elements.
- Foundations, footings and base structures.
- Installation of elements, with metal or mosaic cladding.
Projects in UHPC
- Opus incertum aurichalcum (Rennes, 2025), with Gilles Brusset and SOLIDSTUDIO: black through-coloured UHPC. A sculptural wall 30.50 m long, 1.50 m high and 0.30 m thick with an integrated bench and an emblematic table 1.50 m in diameter and a 7.00 × 1.50 m stele laid flat on the ground, clad in polished brass and mosaics.
Who is it for?
Artists, landscape and architectural firms, and public and private clients. We get involved right from the application stage to assess the feasibility of the artwork and estimate its production costs.
