Uh, Detective Parson, madam.
We built the house 24 years ago and due to planning laws at the time, couldn't build up to the fence line (althougth there's nothing there, just parkland) so we had to have a single garage and I built an (illegal) car port later on the side of it. Carport area was paved with a sheeted roof with a roller door at one end and the other opening on to a fully enclosed patio area.
About 18 months ago, as planning laws have changed, we extended the house roof over the old carport area with a brick and glass brick wall down the side and a properly laid slab. Since then the mortar in the old wall seems to be decomposing; see photos.
The old carport area was weathertight and I didn't notice this in the past.
At the moment I have to vacuum the wall every few weeks.
Any builders out there want to offer a suggestion?
