A client has asked us to replace a 6 ft fence panel with a 6ft rendered wall. It will be free standing so I'm thinking should be reinforced somehow. It can't have piers as he wants it to be a clean block. His little kids will be using to kick a ball against.

I'm thinking 9 inch hollow blocks with rebar or scaffold tubes going down into the footings?

What do you reckon?

Any better / easier way?

Cheers,

John

surely it would be easier just to build in 9 inch H blocks and paint it?
the render is going to take a pasting off kids
obviously rebar in the footing which ideally would be a slab type 900 wide by 300 deep

Thanks For this LLL.

You're probably right about the render but I know what he's like. He'll want to do it anyway.

What's the calculation to make it a 900mm wide slab?

I am no structural engineer
but I have dealt with loads (geddit?)

if the wall is fixed into the foundation via rebar , what you do not want is rotation
the wall is unlikely to sink downwards but a wall that high even at 215 can be pushed over by lateral force
so a wide slab gives an upside down T making the whole thing less likely to go
love to see the render after 9000 penalty kicks :;):

Ok Cheers, I'm with it now.

I Knew the slab should be wide but not that wide. Problem with it is, and this is a common problem with wall foundations in my experience is that doing this we'll have to undermine his paving and go into the neighbour's garden by a fair distance.

With structural concerns and render worries I think I may tell him to think of a plan B :)

The footing can also be straight down but i dunno what the spec would be for your 6ft wall. Last wall that i built that was tight on room had a footing the same depth as height 4ft, i'm sure that is going to be different for a 6ft wall, but by how much ?

niall - the client doesn't want any piers, he wants a flat block. I suppose it could go on the back though.

Jay - Are you saying your footing was 4ft deep? that's full on
