Nouvel ouvrage sur la pierre sèche

PIERRE SÈCHE

Théorie et pratique d’un système traditionnel de construction

Editions Eyrolles

sous la direction de Louis CAGIN

 

« Le succès rencontré par Construire en pierre sèche, le premier livre dans lequel Louis Cagin présentait, à la manière d’un manuel pédagogique, la technique et les méthodes du murailleur, révèle le regain d’intérêt que suscite le patrimoine de la pierre sèche.

Professionnels, membres d’associations, agents au sein des institutions : nombreux sont ceux qui, aujourd’hui, promeuvent et développent cette technique ancestrale de construction qui répond pertinemment aux enjeux environnementaux et économiques de notre époque.

Dans ce contexte, Louis Cagin a réuni des spécialistes issus de diverses disciplines pour proposer un livre de référence. Archéologie, ethnographie, géographie et sciences physiques ont été notamment convoquées en même temps qu’il a été fait appel à des paysagistes ainsi qu’à des praticiens — tous partageant une même passion pour la pierre sèche.

Le geste du murailleur est le principal personnage de ce livre ; il s’exprime sur le terrain, à travers un savoir-faire. Il s’agit d’une technique dont la difficulté réside dans son obligatoire adaptation au matériau qui, par nature, diffère selon les territoires.

Complémentaires mais indépendants, les six chapitres dont ce livre est composé offrent ainsi autant d’entrées possibles par lesquelles les auteurs se sont appliqués à nous transmettre leurs connaissances en s’appuyant à part égale sur leur expérience professionnelle et sur leur sensibilité. »

Bruno Pan Lopez succeeded his father at the Pan Lopez marble factory in Mauriac

 

In 1965, André Pan Lopez, from Bordeaux, arrived in Mauriac. He entered the General Marble as a workman. After passing a CAP from tile-maker to free candidate, André Pan Lopez created a company that quickly specialized in marble. After a few years in the Rue d'Enchalade, it was the first to settle in the newly industrialized area of ​​Avenue Augustin-Chauvet.

In 1977, the couple developed their business by opening a funeral warehouse on rue Marmontel. Simone takes care of the reception and the sale whereas André takes care of the sites.

Bruno, meanwhile, trains as a stonecutter at the lycée des métiers du bâtiment in Felletin (Creuse). He adds a complementary mention of sculpture and engraving that he obtains in Remiremont (Vosges). The young man cultivates the passion of stone and translates it: "To pose it is one thing, to know how to work it is another".

It is natural that he joined the family business after his military service in 1986, and completed his training in contact with his father. "He knew how to do everything and I wanted to do everything."

In 1990, when the State abolished the communal monopoly of funeral services, the Pan Lopez family took over and the business grew rapidly. The store on rue Marmontel is transferred to its present location, at number 2 Rue de la République. Over the years, the workforce has grown to seven employees.

The year 2000 marks a turning point with the opening of the funerarium. The initiative is a bit of a bet, at a time when families have a tradition of keeping their deceased at home, right up to the funeral. "We went very slowly," recalls Bruno Pan Lopez. We proposed this service as a possible solution. " A choice that today sounds like an obvious, because passed in the manners.

Manners of which the marble-maker notes the evolution. "Granite has virtually replaced the Volvic stone and now, thanks to computer science, people can visualize and choose models of tombstone."

If Bruno Pan Lopez likes the trade he has chosen, it is worth his trouble: "To do it, you need a heart behind the carcass. We accompany people in the worst moments and it's not always easy to cash in. " So, the entrepreneur feels the need to be surrounded "My family, buddies and sport," he enumerates. I am like a Saint Bernard who is helping in the mountains. From time to time, I need the little barrel drop! "

Stone Crusher and Separator

 

 

TECNOPORRO s.a.s., specializes in the clarification and purification of water and sludge from the working processes of marble, granite, ceramics, and other materials.

 

One of their best product, the 250-80M3 crusher and separator is designed to recycle waste or scraps (with a thickness of 5 to 100 mm) that occur during the work of stone, marble, granite, ceramic , of glass.

 

The task of the crusher is to reduce the particle size to less than 25 mm in order to be re-usable in other types of work (gardening, mosaic, road filling, layout, etc.).

 

 

Since April 2017, Technoporro also offers this machine in the form of leasing for a minimum of 24 months, up to a maximum of 60.

 

New Director for the MECD Institute

 

Polytechnic engineer (X81) and doctor of physics, Thierry Braine-Bonnaire has been in charge of the MECD Institute since 28 February 2017. Previously, Thierry Braine-Bonnaire has always worked in the construction sector: project engineer at Coyne and Bellier (now Engie / Tractebel Engineering), responsible for the fire safety department of the Scientific and Technical Center for Building (CSTB) and then, at ArcelorMittal, in charge of Innovation in the Corporate Construction department before having responsibility for the Construction Portfolio within Global R & D. More recently, he was Director General of the National Center for Expertise in Envelope and Structure (CNEES), created by the French Building Federation (FFB). Thierry Braine-Bonnaire, head of the recently recognized MECD Institute "Tremplin Carnot", has the mission of deploying synergies among the members of the MECD Institute and of invigorating partnership research with the construction industry. He is also responsible for increasing the notoriety of the MECD Institute within the ecosystems of the Carnot Institutes and, more generally, of research. He promotes the vision of a modern, innovative and sustainable construction making the most of the mix of materials.

 

Founded in 2010, the MECD Institute brings together the four industrial technical centers (CTI) of the construction sector: CERIB, CTICM, CTMNC, FCBA, and four university laboratories: Institut Pascal (Université Clermont Auvergne, CNRS), LaSIE Rochelle, CNRS), LMDC (INSA Toulouse, Paul Sabatier University), SPCTS (University of Limoges, CNRS). The CTI Network, the coordinating structure for ITC activities, is also a member of the MECD Institute.
