The InvisiWeep is the almost invisible wall weep from Timloc. 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.

 

Use: Any situation where water must be discharged from an external wall, e.g.:

At ground floor slab level

Within cavity tray systems

Over external lintels

On external masonry 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 builds

 

Discreet 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

 

Technical Information: Cavity wall weeps or cavity drain units should always be installed in cavity masonry walls to allow drainage and ventilation at regular intervals. They are required at ground floor, below DPC level, and must also be provided as part of any cavity tray run, including roof butment trays, over lintels and continuous cavity tray systems, such as gas protection barrier systems. Unfortunately, many sites are still providing a weep hole facility by simply leaving the perpend joints between bricks open, these open joints are prone to being filled. Perpendicular joints left open can be very noticeable and result in an infestation of nest building insect and small mammals and allow the ingress of driving wind and rain, which leads to the need for a proprietary weep unit such as the InvisiWeep. The InvisiWeep has been designed and flow tested to optimise the discharge of water while meeting the requirement for a small concealed outlet size
