Weep vents in rendered block walls

[Lincolnshire Ian]

Hi

We are building a TF house with a block and render skin. 

I am struggling to find weep vents that are long enough for the block + render thickness. 

Can anyone help with this please? 

Thanks

Standard are fine 

They don’t need to go all the way through 

I always use clear for render with just the 10 mil outlet left showing

Just been 'rendered' this week. Here is a photo. Renderer cut off the ends to be flush with the render and stuck screw or something in the ends to stop them clogging up.

Fortunately the buff colour close enough to our render anyway. Using clear ones is a very good tip though.

(With our builder you only got whatever was in stock at the local merchant unless you searched it out and bought it yourself.)

I don't imagine anything is ever going to come out of them. Weird things really and must compromise any small insulation benefit from the outer concrete block leaf.

Brilliant, that looks good. Thanks for your help.
