Keeping cavities clear.

[syne]

Is there any reason I couldn't close the cavities horizontally at 1st floor level?

 

So far my cavities are very clean, I'm very carefully laying blocks and removing any droppings, even hoovered them out.

But as I approach the 1st floor I can't clear any thing that does drop.

 

Would a cavity closure be a bad idea?

It's getting eps blown in afterwards.

Is it a waste  of time and effort?

Lay a batten on the last row of wall ties you installed and lift it out to clean off any droppings. 
 

if you put a cavity closer in you will need to put in a cavity tray above it to shed moisture to the outside, this could create a weak joint all around the building.

Agreed,

 

I put in boards in the cavity at grounds floor window level that I removed after building via the windows that caught most of the mortar droppings.
