Preformed self-supporting horizontal damp proof course (DPC).
Preformed self-supporting horizontal damp proof course (DPC).
Conventional cavity barriers rise a minimum of 150 mm within the cavity and are supported by being built-into the nearest/ highest inner skin course.
When the inner skin is constructed of blockwork, the course is regularly higher up, therefore the formation uses additional material. This formation also creates an arrangement where the barrier top must be linked with the oversite membrane, a necessary requirement when protecting the building (and its inhabitants) against contaminated land gases such as Radon.
Rise and Fall Barriers are self-supporting and offer the convenience of starting within the outer skin and finishing within (and beyond) the inner skin at the same level. A more easily-managed build sequence and compact protective arrangement is secured. Integration of barrier and oversite membrane is at the lowest possible level.
Supplied in long lengths with internal and external angles and a range of stepped links. Once bedded onto both skins and joined utilizing sealing capping profiles that straddle abutting sections, raising of the cavity wall may continue. Barriers are usually supplied with the inner skin section projecting 150 mm beyond the inner skin internal face.
This permits the membrane and barrier to positively integrate. Important: Overlapping of Rise and Fall Barriers is not possible. Adjoining sections must be butted together and tape linked.
