Solution guide for building with hemp

Lime/hemp solutions are used more and more, in new construction or in natural renovation, to provide a comfortable habitat, thermal and acoustic insulation, in addition to a Humidity control.


Heritage conservation & restoration

In Restoration and Conservation Projects, it is of the utmost importance that mortars are compatible, chemically and mechanically, with the existing mortars and with the building materials present.

Renovation & retrofit solutions

In renovation projects it is important to consider the building as a whole that evolves over time and needs to be preserved for future generations. By choosing and applying a high-quality solution from Saint-Astier®, you are ensuring an aesthetic and durable renovation, sympathetic to the existing structure.

Hempcrete & eco-build constructions

Hemp and Lime construction, renovation and retrofit methods are used primarily to create eco-friendly, sustainable and insulating floors, walls, partitions and attics. By using Saint-Astier® eco-build solutions with carefully selected and calibrated hemp, you reduce the overall CO2 cost (impact) of the materials and your work.
