I've recently had a couple of air bricks added at the side of my property to our lounge.
The air bricks were installed below ground level so I now have a 2 foot hole with an air brick at the bottom.
Any ideas how i'm best to fill the hole but allowing the air brick to still allow air flow?
I was thinking some sort of half box section and then building the dirt back around it.
My concern currently is that if it rains heavy then Water may enter the air brick. The ground is mud so I can dig a small over flow below and away from the air brick.
Hope the above makes sense and any help/advice would be great.
