The G951 Peep Weep provides an unobtrusive solution to cavity wall drainage requirements. The weep features a mortar key to ensure adhesion to the building fabric and an external rib to aid positioning. The rib surrounds a 62 mm high opening to prevent mortar blockage from within the cavity.

A protective hood 'peeps' out from the face of the masonry to guard against blockage during installation and prevents penetration of wind driven rain. The exit hole is ample for water drainage, but small enough to prevent entry of large insects.

The G951 should be simply fitted in open perpend joints and mortared in position leaving approximately 10 mm protruding from the masonry face. It should be spaced at no more than 900 mm centres: NHBC guidelines recommend 450 mm maximum centres, with at least two weep vents above all windows and doors.
