USES OF STONE





Traditional Masonry:

Common Sedimentary oolitic limestones which are freestones meaning they can be cut in anyway direction, yet can cut and fashioned with hand tools ,used for Traditional masonry.

There are many such stones in UK, Portland and Bath are best known. Similar geological sources occur across the Channel particularly CAEN stone, with which most of our medieval cathedrals were built.

There is a demand for sedimentary limestones in raw bloc form to be worked masonry factories in UK. Our factory facilities in France are similar to those in U.K.

Such Stones are : cream limestones CAEN, St. Maximum, :White, Martel, Lavoux, Buffon, : Yellow Lanvignes.

Thin Wall Cladding:

Some of the more densely compacted sedimentary limestones can used at thinner section. However in Burgundy we have metamorphic limestones which are not marbles - these are called Hard Limestones. They are fully recrystalised as a result of geological heat and pressure.

Hard limestones have the appearance of limestones , combined with the strength and durability of Granite

Hard limestone inthin wall cladding, can be 40 mm thick or cast onto to concrete at 30 mm thick. These are usually as a rain screen system where every stone is individually supported.

Such stones as Marmont, Comblanchien, Chandor, Villebois, Ruoms, Corton.

Internal Floor and Wall Finishes:

Generally favoured are compacted sedimentary stones and hard limestones for more intense use.

Here also appearance is consideration decorative stones such as Beauvillon and Ruoms and Corton make an interesting and individual floor. The use of several difficult colour stones can be worked into design.

Low porosity in compact sedimentary limestones and almost zero porosity in hard limestones is important to keep floors clean. Hard Limestones can be used without an impregnator.

Compact Sedimentary Stones: Buffon B5, Beauvillon, Lanvignes , St. Marc jaune/ d'ore :

Hard Limestones, Comblanchien Chandor Villebois Ruoms Bleu de Savoie light/dark St. Baudille.

External Paving:

The most durable are frost resistant Hard Limestones, which are flame textured for slip resistance. Hard limestones at almost zero porosity will not allow water penetration , therefore remain clean in natural weather and are also resistant to frost.

Slip resistance due to flame texturing is excellent initially, but will wear. The best results are by following a cleaning regime using Mattguard which prevents the surface becoming shiny.

There is a wide variety of colour in hard limestone White ,cream, gold, grey, brown. this allows for concourses to be designed in several stones

Due to the high flexural strengthof hard limestones, thinner stones can be used for example 30 mm for pedestrian paving on well trafficed concourse. Therefore the cost is reduced.
