Features and benefits: • 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 builds • 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 • Extension tube available for wide walls and render. This innovative new wall weep can be used in any situation where water must be discharged from an external masonry wall. It is perfect for use with the Timloc cavity tray system, over external lintels and at ground floor level. It has many innovative features that are patent pending, including a Venturi effect outlet tube that reduces water pressure, allowing for optimal drainage.
