We have stalactites in our walls!

Category: Barn Conversion Journal December 23rd, 2007 by mbc

Rather strangely, I’ve we’ve discovered stalactites in our walls.

Whilst the photograph is not that clear, that downward dribble to the right of the centre of the picture is a lime stalactite that has formed within the south facing wall of the barn. Whilst the wall is not very damp at the surface, internally it is quite wet and obviously sometimes runs with water. Whilst lime is supposed to breathe, this amount of moisture would take colossal lungs to exhale! That aspect of the building has been recently (over the last 10 years) repointed with what I thought was lime mortar so this comes as something of a blow and an unexpected piece of work. On close inspection the pointing is cracked, even rotten in places and some of the smaller joints have not been pointed at all. All in all it seems a bit of a botched job with plenty of opportunities for rain to get into the wall – that wall is pretty exposed and likely to suffer driving rain over the winter.

We’ll need to hack out the mortar and repoint the wall in an attempt to remedy the problem. We can officially claim this to be Hiccup #1

Lime Wall Pointing

From the back of the barn, along one side of the ‘garden’ (the enclosed area to the back of the barn) runs a mortared stone built wall.

Building Progress ~ April 2008
I can’t believe that April is drawing to a close and I’ve not managed an update since the end of March.

  4. Lime pointing ~ before pictures | my barn conversion Says:

    […] Unfortunately, despite originally thinking that the pointing was good and sound having been recently repointed with what we thought was a lime based mortar, the repointing had actually been done with a cement based mortar that had cracked over time and so let in a lot of water. That end of the building catches the worst of the weather as it blows in along the valley and so is exposed to plenty of rain year round. So much water had worked it way in and dribbled down inside the wall that we had stalactites in our walls. […]
