Slated membrane maintenance
Self-protecting slated mineral membranes are often chosen for visible waterproofing in order to avoid painting maintenance. These membranes, apart from ensuring watertightness thanks to the layer of mineral slate on their surface, are not subjected to UV rays and therefore the bitumous mass does not suffer.
The granules are usually made with flakes of natural slate therefore a slight chromatic difference can be seen due to the nature of the product. The quantity of slate applied is approximately 1kg per m² and an initial granule loss at the beginning of a project is perfectly normal, normally there is a tolerance of up to 15%, which occurs because not all the slate flakes manage to penetrate the bitumous mass during production.
