14 Securing the position of lightning conductor holders

EVALASTIC® waterproofing membranes have a very smooth surface, so that holders must be secured against sliding away or shifting

  • on roof slopes of approx. 5 % and more or
  • if the membranes are loose laid and mechanically fastened.

The following methods for securing are available

  • EVALASTIC® tapes, with rounded off corners, arranged in direction of the slope which are conducted through the holder 37 and welded at their ends to the roof waterproofing with an overlap.

On mechanically fastened waterproofing membranes, the lightning conductor holders are positioned directly next to the membrane fasteners.
