The almost-invisible, multi-function wall weep for discharging water from external walls

• Integral 4mm vermin barrier and rainwater baffle as recommended by BS5250, to reduce ingress of large nest building insects, mammals, and rainwater penetration to the cavity
• External ribs & tapered profile, to key into mortar for secured fixing
• Full height upstand to cavity side, to maintain drainage and minimise the impact on blockage from cavity cement build up
• Discrete water outlet, to minimise the impact and reduce visibility for a truly concealed wall weep
• Venturi effect outlet tube to reduce pressure, allowing for optimal water drainage
