house airbricks below conservatory floor level - what to do?

[staithes14]

OK, building a conservatory: the house has two airbricks below dpc level, so therefore also below conservatory floor level. In other words they'll be buried when I lay the floor.

Not sure what to do. How important are two airbricks from a common space under the floor, which is served by numerous other airbricks all round the house? My temptation is just block them off and forget it, but is this likely to lead to any issues?

Technically this is what you should do: http://www.diynot.com/forums/viewtopic.php?t=171482 scroll down to the photos

Hmm, so I need a continuous channel from the airbrick to a new airbrick on the dwarf wall. What if I don't do this? As I said, there are plenty of others around the house.

Probably be fine.
