We offer comprehensive advice and practical support in the areas of restoration, monument preservation and new builds and conversions.

Now new in Switzerland:

We distribute and process the exclusive lime mortars from Calchera San Giorgio.

These high-quality materials are ideal for the sensitive handling of historic buildings as well as for new builds and conversions in the private and public sectors. Our main focus is on durability, healthy living and sustainability.

Whether indoors or outdoors, our products are versatile. They are tried and tested in practice, tested and meet all current standards. They are completely free from cement, gypsum, soluble salts and plastics.

The positive properties of pozzolanic lime mortars based on ancient recipes are remarkable: they allow water vapor diffusion similar to clay plaster or other natural lime mortars, but offer significantly higher hardness and durability. In addition, they have an active effect on the indoor air - they are antistatic, clean the air and, with their high pH value, have anti-mould properties.

Avoid the annoying consequential damage that conventional "modern" building materials can cause over the years! These products consume valuable resources, put a strain on both the environment and your budget and offer no added value for your health.

Enjoy the positive properties of our materials - from day one! The timeless beauty of the surfaces remains intact even after many years and always retains its aesthetic validity.

Make your project sustainably successful with antique knowledge!
