The covers with the ceramic finishing are the most common. We can waterproof the cover using the existing finishing or we can pull it out and then install the waterproof and ceramics (it is a more correct way to do it).
The films come in rolls, once they are extended they get welded by thermal fusion. This welding is permanent and when the films are welded they form one solid piece. This piece is delivered to the perimeter of the cover as well as to the various elements composing it (downspouts, tubes, skylights) in all cases we protect it with a geotextile on top and bottom.
All of our waterproofing works have a 10 years warranty on materials and workmanship.
