Internal Basement Waterproofing on the Foundation Plate with Cold-Adhesive Waterproofing Membranes

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 10 SY. At the wall floor junction a fillet made from KÖSTER Repair Mortar plus has to be installed to prevent stresses in the subsequent waterproofing layers.

The priming is done with solvent free materials such as KÖSTER Primer BL or KÖSTER KBE, 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 applied KÖSTER KSK Membranes have to be protected from mechanical damage as work continues. It also needs to be connected to the vertical waterproofing of the adjacent walls.

Always adhere to the specifications in the respective Technical Guidelines.
