Tapes are a basic element of every waterproofing system. They are used in corners, expansion joints, but also, what contractors often forget, connections of sheet metal flashing or eaves profile with the concrete part of the terrace or balcony. This is where leakage problems first appear due to the higher stresses caused by the different expansion of the two materials, concrete and steel. And it is in this space that WB TAPE PRO tape works best. Firstly, it has vulcanizing properties, which makes it perfectly bond to steel, and secondly, its high elasticity allows for the transfer of cracks and thus maintaining the tightness of the insulation. There is no need to create bonding layers on the sheet metal flashing in the form of resin and quartz sprinkles. Just clean the surface of the sheet metal with acetone, tear off the protective strip on the tape and stick it on.
One of the very critical places where leakage occurs is the window-wall junction. Due to constant vibrations and movements of these elements relative to each other, it is important to seal using appropriate technology. Butyl tape is used for this type of solutions WB TAPE.
After gluing it to the window frame, the vulcanization process with the substrate takes place, thanks to which you obtain a tight and solid connection with the window frame. After gluing, we apply the highly flexible Water Block Duo Flex insulation both on the tape itself and on the wall and balcony slab elements. In this way, we have made a solid first layer of waterproofing, on which subsequent layers of the balcony system will then be placed.WATER BLOCK.
