7.3 Membrane Termination
The waterproofing system must be suitably terminated to the
surrounding construction to prevent water penetration ‘behind’
the new waterproofing system.
Depending upon the nature of the installation and construction,
the membrane should be protected with a ‘Cover Flashing’.
Alternatively, the membrane may be secured with a ‘Termination
Bar’ which is then weatherproofed by pointing a suitable mastic
sealant along the top edge between the construction and the
Termination Bar.
The waterproofing should finish on the vertical a minimum 150
mm from the finished roof level or in accordance with national
regulations.
In the case of roofs with paving or other coverings such as a green
roof, the 150 mm should be from the uppermost finished level,
and not the level of the waterproofing.
Flashings
The flashing should provide sufficient coverage of the
waterproofing, extending down a minimum 75 mm over the
waterproofing system.
Termination Bar
Depending on the method of installation and the type of
termination bar used, the waterproofing membrane may first
require mechanical restraint using the Icopal Fixation Bar. The
termination bar is mechanically fastened to the wall at regular
fixing centers. A suitable mastic sealant is applied behind the
lip of the termination bar just prior to the final tightening of the
fasteners. This provides a compression to the sealant ensuring
that the detail is sufficiently weatherproof. The sealant has to be
checked regularly.
