Always part of our nature, designing in a workmanlike manner manifests itself in our company through a double facet: the first concerns the realization of specifications for the building site, designed and studied according to the UNI 11333-1/2 standard which indicates dictates of the correct installation of waterproof membranes in a workmanlike manner.

The second refers to the creation of artistic works using the same bitumen used in the production of bituminous membranes as decorative elements. The paintings, made also thanks to the collaboration of our line employees, are now part of the decor of the production department.
This is to remember and summarize the broad vision of which the concept of art is composed.


In our corporate vision, art is considered as a broad concept that does not concern only the artist himself, but any person involved in producing objects or making products that are used by man to satisfy needs or solve problems.

For us detail, designing in a workmanlike manner means considering and refining every single one that makes up our production process the creative ideation that is carried out inside or outside the company sphere, such as participation in conferences and fairs.
As a company we are committed, every single day, to the adoption and application of this thought.

Industrial Elegy

The commitment to produce as a 'work of art'

We believe that the "art of making" and the "made as a work of art" are a modality referring to man in general and to the totality of his works, not only to his artistic expressions. This is our point of view. This is our daily commitment.

Architect Flavio Albanese will tell us about this, in the video of the famous director Riccardo De Cal.


1993 - 2022

Beyond twenty-five years dedicated to design, produce and sell in Italy and all over the world waterproofing systems; dedicated to study and research solutions and products with successful characteristics and performance in a Certified Quality System (ISO 9001). Twenty-five years lived to safeguard the environment through the conscious usage of resources and the constant reduction of the production impact also using renewable sources (ISO 14001).

Twenty-five years spent in the commitment to make the workplace more and more pleasant, with particular attention to the health and safety of all employees (OHSAS ISO 18001).

Twenty-five years invested in promoting sustainable development in construction also through the realization of integrated photovoltaic systems (USGBC).


It is General Membrane's belief that the value of the Company lies not only in its ability to optimize production and income processes, but also to contribute to the social, cultural and environmental sustainability of the reference context.

Respect nature and in particular the place where the company produces; create safe, healthy and stimulating work environments; spread the taste for quality and innovation; enhance the territory and the technical, artistic and architectural culture: the entrepreneurial mission of General Membrane is also recognized for these aspects.

General Membrane Loves Earth is the project that aims to realize the Company's commitment to the environment.
