Fast, easy application without long waiting times: Waterproofing of the floor slab with KÖSTER KSK cold applied, self adhesive waterproofing membranes.
To avoid rising moisture, it is necessary to install a horizontal barrier underneath the wall with KÖSTER Fix-Tape 15 SY.
The priming is done with solvent free materials such as KÖSTER KSK Primer BL, KÖSTER KBE Liquid Film, or KÖSTER Bitumen Primer. As a standard the primed surface of the floor slab is waterproofed with the cold applied, self adhesive waterproofing membrane KÖSTER KSK SY 15. Overlap the joints 10 cm. The waterproofing layer is carried up the wall and secured with the KÖSTER Butyl Fix-Tape Fleece
The applied KÖSTER KSK Membranes have to be protected from mechanical damage as work continues. Before pouring the screed or self-leveling underlayment, a gliding layer of customary PE-Foil is applied. KÖSTER SL Premium is ideal for protecting the surface. The system aso needs to be connected to the vertical waterproofing of the adjacent walls.
Always adhere to the specifications in the respective Technical Guidelines.
