BLANKE DISK is a revolutionary waterproofing system made of polyolefin foam that does not require tile adhesive to bond with the substrate. Much of the damage caused by moisture results from badly-installed sealing, and mostly occurs in the transitions from the wall to the floor, or by leaking overlaps. Impossible with BLANKE DISK! The full-surface adhesive with flush-fitting interleaving overlapping joints is 100% watertight. The composite sealing can be glued directly to floors and walls. Large format tiles can subsequently be laid without problem, and without the need to wait.
