stone capping on 45 degree wall

[George Miles]

I have a sloping 45 degree wall which want to cap with stone, overhanging on 3 sides for rain drips.

How to fix it so it wont slide off over time?

George Miles submitted this idea :

Drill a hole or holes (very carefully) in the face of the stone intended to fit to the wall, use plugs and stainless screws partially screwed in, then matching holes in the top of the wall to accept the heads. Sand and cement into place as normal, between stone and top of wall.

Once set, it will not move.

Might be easier to screw a hip iron to the wall _under_ the capping, albeit more intrusive visually as most are designed to go under the top course.

Might be a useful place to hang coats though ;)

The party wall in the roof of my Victorian semi is like that.

At the bottom end, there is a carved stone which replaces a few bricks and has the coping stone as part of it. Wouldn't be difficult to make some shuttering and cast one up from concrete.

There are several stairs outside my mother's place that have that exact arr angement except the wall levels out at the end and the last capping stone i s set horizontal, this seems to do the job. I know there are no other fixin gs as I saw them do the cappings.

As on the parapet walls on rooves of this and many other Victorian terraces around here. But I thought it'd be OTT to suggest the OP rebuild the wall so the last bit didn't slope.

[Tricky Dicky]

He would not have to rebuild the entire wall just put in a couple of course s at the end of that slope to leave a horizontal end and set one capping st one on top, or "kneeler" as someone mentioned. Not much extra work if the O P is already capping the entire wall.

With _my_ ability as a bricklayer it[1] would be a lot more work if a neat job was require :(

[1] The walls I've seen finished like that have had a full capping stone at the end. That's usually 600mm these days. With a 45 degree wall I thought that needed 7 or 8 courses at the end. And while he might get away with a short length, ISTM that risks it being pushed off by the stones above.

Whatever you choose just don't use sawn galvanised steel. The bare ends wil l rust without delay. and in time that'll make a royal mess.

I think it looks better than the other common method of a kneeler at the end.

No big deal casting concrete.
