Iím hoping for some advice about how high I can have an area of block paving Iím laying outside my house.
The wall has airbricks, the top of which are 150mm below the DPC (which is about 60 below internal floor level). The paving will slope away from the house, but ideally Iíd like the level to be flush with the top of the airbricks (or even a little higher).
I was planning on creating a 200mm wide channel of gravel along the wall - presumably I canít cover the airbricks with gravel, but if I create a space around the vent so itís got 200mm free in front and its open upwards would that do the job, or do I need to suck it up and excavate 200mm below the vent so the paving ends up flush with the bottom of the airbrick?
