Introducing Diamond Weep®
Providing a robust and discreet solution to cavity wall drainage requirements.
With a unique diamond shape profile helping 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 joint, 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 entry of large insects.
Diamond Weep is available from a range of national merchants and independent distributors and is offered in a clear version plus a range of seven additional colours to match various wall and mortar finishes.
