Opus incertum in Burgundy limestone
Opus incertum – Sawn

Opus in natural stone.

We work on 2 types of opus incertum n: opus incertum brut in Burgundy stone and opus incertum sawn. In general, opus incertum is a stone with varied and irregular formats (length and width). We must not confuse the opus incertum with the Roman opus which is a specific layout.

The sawn opus incertum is a set of slabs in various formats made from different stones, ranging in color from golden-yellow to light beige (Ampilly, Lanvignes, and Semond). These stones originate from the Châtillon-sur-Seine region. Currently, our stock consists exclusively of Ampilly stone. The pallets contain a mix of different finishes (honed, brushed, monastery). The average slab size is 30 x 40 cm, but there are also smaller and larger pieces (up to 60 x 40 cm).

The price is unbeatable for French natural limestone, making it an excellent choice for terraces or pathways. This is due to our workshop process : as a manufacturer, we cut and shape our stone blocks into calibrated paving. When we reach the end of a block and there is not enough material left for a standard-sized slab, we recycle these "offcuts" into opus incertum, creating multi-format slabs.

These stones can also be trimmed by hand to create rectangular slabs in various formats (see photos 1, 3, and 4). In this case, you should plan for twice the amount of stone needed for the surface area to be covered. While the price remains very affordable for natural stone, the installation requires a significant amount of work.

We always have stock calibrated in thickness 2 cm.

Note: These opus patterns are sold by default without the IG Pierre de Bourgogne designation and are simply labeled as opus in Châtillonnais stone. Upon request, we can provide opus with the IG Pierre de Bourgogne designation.
