Hi I'm currently building an extension on the side of my house. The ground floor is a garage with a bedroom above.
My question is this.
The existing external house wall has 4 airbricks inserted in it directly below the DPC across its length.
I want the garage floor level to be above the level that these airbricks are which would mean either running channels through the floor and putting new airbricks in the new side wall. or covering them up.
I have been looking into the purpose of these airbricks and do not understand why they are there.
All our internal floors are solid concrete built off the ground and our cavities are filled with insulation.
I have had a look into one of the airbricks and as far as i can see they are channeled through the cavity but then close at the inner wall.
Is there a purpose to these airbricks and would it cause a problem if they were covered over.
Thanks
Dave
