Radcon not only replaces all currently known above grade membrane applications but of course by default becomes world best concrete protection technology.
Generic sealers such as silanes, siloxanes, methylmythacrylates and even silcates can only deliver general concrete protection without again addressing the weakest point, the cracks present.
Sealers are most often used as a general preventative for freeze/thaw damage, ingress of airborne pollutants and some protection from de-icing salts.
One will find that a 2 coat specified, 100% solids content silane will be substantially more expensive at an applied price than a single Radcon lifetime waterproofing application.
