The founders Jean-Louis Queyras and Bruno Verny having respectively received public works and construction training , the STAM company has been able, since its creation, to carry out as many masonry works as VRD.

The arrival of Guillaume QUEYRAS made it possible to develop the Civil Engineering branch and more specifically water treatment (Wastewater treatment plant, Reservoir, etc.) .

From the year 2010 and in order to meet the specific demands of its customers, STAM developed in the general contracting sector and this through competent secondary companies encountered over the years.

Listening to changes in an innovative sector, STAM responds by adapting to new techniques as well as new environmental and societal requirements.

Minimization of environmental impact

For several years, STAM has been implementing an approach aimed at reducing the environmental impact of its worksites. Indeed, through several pilot projects such as: the Digne wastewater treatment plant (first HQE wastewater treatment plant in France and green site), CAP 88 site, Gap Hospital … STAM has had the opportunity to set up a set of procedures and construction systems that reduce the environmental footprint of its worksites. This approach has now been systematized and has resulted in the systematic implementation of construction processes.
For 10 years, Stam has surrounded itself with effective partners in waste management ( PAPREC ; SITA SUD; VEOLIA ENVIRONNEMENT ) waste is sorted and valued systematically.

The laitance of the concrete is a factor of soil pollution, STAM has equipped itself over the course of its worksites with a washing podium and a settling tank in order to recover the washing water.

The formwork oils used on this site will be stored in retention tanks to avoid any dispersion on the site.

When ordering, STAM favors the most suitable products in terms of quality, availability and distance.
