Gray granite Tarn retained by Toulouse, France

We know the pavement that will develop the forecourt of the canal between the Matabiau bridge and the Riquet bridge: on the central part, facing the station, it will be a gray granite Tarn identical to that of Bayard Street and aisles Jean Jaurès. A choice that ensures a will of continuity and readability of the facilities between the station and the city center.

On the north and south-boulevards Bonrepos and Pierre Sémard, pavement coverings are planned: for the greenway side Canal du Midi: a serious limestone emulsion and for the pavement side side: a shot blasted with granite border. A coating that will allow both the ease of maintenance and the possible modification of street furniture.

The company Marsac becomes Design Marbrerie

Under the Marbrerie Design brand, Laurent Benoiton took over the Marsac company from rue d'Artiges in Chauvigny.

Previously settled in Mignaloux-Beauvoir, Laurent and Émilie Benoiton have taken over since July 1, the chauvinist company of funerary marble Marsac, located rue d'Artiges.

Under the brand Design Marbrerie, the couple, from the Indre, offers in the continuity the sale of monuments, vaults, plaques, artificial flowers and all cemetery works. "Taking over the Marsac business was a great opportunity for us. It brings us a good volume of business, "says the new manager, who has done some work of redevelopment of the office and offers every month an offer on an exhibition monument.

(1) The establishment of Mignaloux will soon be closed.

FIRST STONE FOR MUDAC AND ELYSÉE IN SWITZERLAND

The opening of the two museums is still scheduled for autumn 2021. The first building of this project, the Cantonal Museum of Fine Arts, will be inaugurated in October 2019.

The first stone of the building designed to house the Musée de l'Elysée and the mudac in Platform 10 in Lausanne was laid Friday. A white marble cube of two parts symbolically marks the meeting of these two entities.

Started in early June, the work is progressing according to schedule and the opening of the two museums is scheduled for autumn 2021, says a statement from the township, the city and the various institutions. This construction site corresponds to the second stage of Platform 10, a museum hub, or "arts district", which will be built on 25,000 m2 just a stone's throw from the railway station in the Vaudois capital.

The first building of this project, the Cantonal Museum of Fine Arts, will be inaugurated in October 2019.

Marble stone

In order to symbolize the meeting of the Elysée Photography Museum, directed by Tatyana Franck, and that of the Museum of Contemporary Design and Applied Arts (mudac) led by Chantal Prod'Hom, the architects opted for a cube, composed of of two white marble elements. "The two parties put one on the other take the image of the two institutions, and touch in three points," said the statement.

To attend the installation of this stone by state councilors Pascal Broulis and Cesla Amarelle, the trustee of Lausanne Grégoire Junod and the directors of both museums among others, some 500 people had made the trip. Politicians, sponsors, SBB representatives, cultural circles or the economy.

For the Musée de l'Elysée, this new building should allow it to double the exhibition surfaces and to bring together the collections' conservation areas by tripling their volume. The mudac will see him doubled his exhibition spaces.

100 million

The overall budget of this project is 100 million francs. It includes 40 million from the state of Vaud, 20 million from the City of Lausanne and 40 million from contributions from patrons and private partners.

Mosaic

The mosaic technique allows you to make drawings, frescoes, friezes, floor coverings ... by assembling small pieces of various materials. The most diverse materials are used such as: clear or colored pieces of glass, silver, wood, shells, various stones ... These recovery materials often called tesserae or cassons can be used as such or re-cut. But we can also use materials made for this purpose such as Briare enamel (proposed in a thickness of 3 cm and forty different colors) Venetian smalt (with in this case the almost infinite choice of shades in a thickness of one cm).

The material used will depend on its availability, but also on the desired application (mosaics of floors made of wear-resistant hard stones, mosaics for pools resistant to water and treatment products, interior or exterior mosaics ...) .

The elements constituting the mosaic are glued on the support using suitable products (cements, coatings, various glues ...)

The technique of mosaic is to form patterns, figures, friezes ... from pieces broken and cut, multicolored, called tesserae or cassons (for broken tiles) and assembled with putty or plaster. We can use ceramic fragments, stone, glass paste or even marble (hard and crystalline rock that is suitable for floor mosaics), Briare enamels (3 mm thick and more than 35 different colors), or Venetian smalt (about 1 cm thick and several hundred colors). But we can also use pebbles, shells, broken mirrors, slate ...

Three different techniques

The choice is made according to the support, the destination and the size of the mosaic:

• the direct method is practiced in situ and consists in directly sticking the tesserae to the place on the support

• the direct method on net (appeared 20 years ago) is done at first in the workshop: the tesserae are pre-glued to the place on a fiberglass frame which is then fixed on the final support, in situ . This technique, often used to create large sets or frescoes, allows to deliver a mosaic ready to pose and thus, to reduce the time of intervention on the building site

• The indirect method (invented in the middle of the 19th century) is also done in the workshop: the pattern to be made is reversed compared to the original because the tesserae are glued upside down on a temporary support, usually made of kraft paper. In some cases, a wooden frame, set around the mosaic, will then be used as formwork to sink a bed of mortar. After drying, the mosaic is turned over, the kraft paper is removed and the mosaic fixed in one piece on the site. If in the direct method, we can play on the thickness of the materials to give relief effects, the indirect method, on the contrary, favors a completely flat surface even with different thicknesses of materials. What is interesting for making table tops or floor slabs

Mortar or tile adhesive

The tesserae and cassons are glued with a mortar made from a volume of cement for a volume of sifted river sand (0.2 mm in diameter), all added water. To slow the setting time (in the case of small tesserae), it is possible to add one or two volumes of non-hydraulic lime to this mortar as well as natural pigments (oxides or earth) to color it when no joint finishing is not planned. Today, this binder - which requires a perfect control of the time of implementation - is more and more neglected in favor of industrial adhesive mortars, identical to those used by tilers, offering different setting times.
