Product info

The unique diamond shape profile helps to increase the drainage flow rate along the base of the channel promoting self-cleaning and removal of debris build-up. Ribs along the angled outer walls also create a more robust mortar key within the perp end to ensure a secure fit within the outer leaf construction.

The face of the diamond-shaped outlet finishes flush with the brickwork for quick detailing into the mortar joints, with the tapering outlet designed for easy cleaning. The rear opening of the weep stands 65mm high, the full height of the perpend joint, as per the guidance of NHBC Technical Extra 17 ensuring an optimum drainage inlet from within the cavity.

The profile of the weep also features a minimum opening point of 4mm which is ample for water drainage but small enough to prevent the entry of large insects. The Diamond Weep is available in clear and in a range of colours to match various wall and mortar finishes.
