Materials and techniques

The stones we work with have a raw and powerful beauty. They are often typical of a region or a land and their use, from villages to cities, tells the story of our built heritage.

Our Gers stone quarry

Located in Biran, we are the last active limestone quarry in the Gers that is capable of extracting this local stone, a distinctive feature of our department. Its density and appearance make it possible to achieve identical renovations to existing buildings.

Its harmonious light yellow ochre hue marbled with chalky white makes buildings both light and warm, like the Gers.

Aurignac sand

Stones and sands

We use different sands of different colours and grain sizes to make our own mortars and to adapt to existing buildings. We carry out suitability tests.

Obviously, we work with Biran stone, Gers limestone par excellence, but we adapt according to the different locations. We are therefore led to work with sandstone, limestone, marble stones, etc.

Walls

The wall frame can be made of coursed stone, mine-run rubble stone, old or new traditional Toulouse brick, but always with a manual finish.

The joints and coatings are made with lime mortar, and the finish offered always adapted to the customer’s requests and to the building to be restored.
