Using flags to cover vertical retaining wall

[David2012]

Hi Guys,

Firstly I just wanted to say.... What a fantastic site, and also how helpful everyone is here!!!

Ok so I have agreed to help out my brother with a new patio, at present he has a very dated patio. He has decided to go for Autmn Brown sandstone.

At present the patio is raised (about 600mm) and has faux stone bricks around the perimeter, which he doesn't like. I told him there are 2 ways to update-dig it all out and rebuild with a different brick, or 'clad' with the same flags.

my question is how difficult will it be to take the second option?? I have some knowledge in plastering so thought perhaps could just cut the slabs to size and stick them to the old wall with some gear? I wasnt sure how well the mortar would bond to the sandstone, would an sbr/cement slurry be needed to create a key?? The actual slab can just be bedded on the footing of the wall so no worries there.

Many Thanks for any help

it can be done david but i feel it would look pants
can he not build another skin of nice new brick or stone work around the existing then slab on top?
or even render the existing?

btw @600mm high legally you should have a hand rail

another point to make is that the edges of the sand stone may not be the most attractive edge
sometimes better to have the wall say 100 mm higher and have the stone laid inside a picture frame of bricks,rather than the flags overhanging if that makes sense?

Larger lout,

Thanks for the reply, yeah I must admit it wouldn't look the best but he's a bit of a tight ass!!

I found him some nice stone on the net that i thought would look nice against the sandstone...... http://www.pavingcentreonlineltd.co.uk/index.php?productID=563

what do you think? can you recommend anything?

He will piss himself if I mention a rail!

yes I see your point on the edges...... especially as the wall will be curved ha ha didn't think of that (embarrased)

So how will I get the fall away from the house if I use the picture frame idea? obviously the brick/stone wall will have to be level. I have to slope everything to existing drains otherwise he'll get a very wet lawn!!

Thanks so much for any help I really appreciate it

its lager, not larger :;):

if he wants the tune he has to pay the piper

that stone looks nice

if the stone picture frames the flags then the stone must too be laid to a 1:60/1:80 fall

sort of like this

so in this instance the flags were laid up to the brick work

he will have heart failure if someone falls off his raised patio and claims against him

you need to spend half a day setting it out and getting it right, the choices are all his

Thanks very much Luton, sorry about the larger business.... funny how the eye can play tricks I saw the word lout and put 2 and 2 together!!

Thanks for the pic, I was just a bit unsure if 12 mm/meter
would look shit on the mortar bed once pointed, I guess the best way to go is get the fall on the 1st course then carry on the same fall keeping the mortar beds the same thickness.

Really appreciate the help

1:80 really isnt a lot of fall,about 15mm on a standard 1200 mm level
the idea is you dont notice the fall but water will still run off
LLLLLLLLL ad nauseum
