Products & Applications
Raw materials
You are stonemasons or marble workers, you will find in our range most of the appellations of French heritage and coming from the main limestone soils.
Our stones are available as rough blocks for new products or for the restoration of Historical Monuments. We have a stock of thin slices, and are able to provide you with thick slices on demand.
Our sales team is at your disposal to select blocks and slices with you, directly on our production sites. For your specific requests, our geologists and our extraction technicians will study the feasibility with you.

Indoor and outdoor floors
Choosing a stone floor means freedom of formats, simple maintenance, high resistance to wear, a timeless patina, the possibility of creating a staircase or matching accessories.
Our range of stone makes it possible to meet all uses in flooring. The following table will guide you, for a first election, depending on the place of employment and the use you imagine.
Respecting the rules of the art during implementation will guarantee the good performance of our products over time. These are described in the DTU 52.1 for sealed installation and 52.2 for glued installation.
Stone paving can also be laid on pedestals, calculating the necessary thickness, and on a heated floor, taking care to separate it from the support.
Outside, it is imperative to choose the stone according to the climate of the region and to manage the evacuation of rainwater (slope, under draining layer, gutter).

Facades
The attached stone
The attached stone makes it possible to make wall coverings made up of stone slabs attached to a concrete or masonry support. A ventilated air space must be provided between the rear face of the plates and the insulation fixed to the support. The insulation thickness is commonly 15 cm and can be up to 28 cm.
Stone slabs, generally 3 cm thick, can have a surface area of up to 1 m² and one of their dimensions measuring up to 1.40 m, if the wind sizing calculations allow it. The fasteners are made up of solid stainless steel legs, adjustable in three directions. They are fixed to the support by metal plugs. Except in special cases, the number of fasteners is four per plate, sized to ensure the absorption of the weight and the forces of the wind. The plate / bracket connection is made by penetrating a stainless steel lug into a larger diameter hole in the edge of the plate.

The self-supporting wall
Self-supporting coverings are made of rubble or dressed stone laid in matching layers. They are 8 to 15 cm thick. Their stability, vis-à-vis the discharge, is ensured by connections fixed to the load-bearing wall. This type of design allows for dwalls having the appearance of massive stone, but relatively thin. It also offers the advantage of allowing the installation of significant thermal insulation from the outside.

Pierre Massive
Stone has always been used to construct buildings. Today it is possible to build in solid structural stone. The stone facades can contribute totally or partially to the structure of the building and can be imagined in association with other materials. Building in local massive stone is a responsible choice which allows to obtain low carbon construction. The use of solid stone will give a strong thermal inertia to your building, which will allow you to benefit from remarkable summer comfort.
With deposits of soft stones spread over all the territory, ROCAMAT gives you access to a material of high environmental quality near you. Our sales team is at your disposal to build your massive stone project with you in compliance with DTU 20.1.
Our stones Saint-Vaast, Saint-Leu, Tervoux, Sireuil are particularly well suited for this type of project, while remaining within competitive budgets vis-à-vis traditional construction.

Innovations
Stone, thanks to today's techniques, adapts to new uses and finds its place in innovative projects. Thanks to digital techniques you can imagine complex shapes and build modern structural assemblies.
We work by removing material, which allows us to create unique pieces and to free you from the notions of series specific to artificial materials. Submit your stone wishes to us and we will innovate together. We have a flexible industrial tool and technical teams that allow us to adapt to the specificities of each project.
ROCAMAT Insulating Cladding
ROCAMAT cladding is a cladding system with a 20 mm natural stone wall associated by gluing with a high density expanded polystyrene insulation 60 to 100 mm thick. The thermal resistance (R) of the assembly varies from 1.58 to 2.63. The horizontal edges of the stone are grooved in the factory. The slabs are mounted on aluminum rails. These are pegged to the support through the insulation. The clothing benefits from a CSTB Technical Assessment.
