Type PWRB Party Wall Rising Barrier
NHBC 6.6.2(d) deals with providing a means to prevent water originating from one dwelling contaminating the adjoinong dwelling via the party wall. The Type PWRB fulfils the requirement in a more cost effective and functional manner. The barrier projects upwardly in the cavity to provide protection, rather than vice-versa (that necessitates work to the slab to provide a channel to falls).
The profile of the Type PWRB is capable of holding back a greater extent of water compared with the channel approach. The profile also makes interfacing considerably easier with any perimeter cavity barriers that might be installed as part of contaminated land protective measures. The Type PWRB Party Wall Rising Barriers are available in numerous profiles.
