Lattice fence above brick wall

[Timothy Murphy]

I want to install a wooden lattice fence on top of a brick wall. The wall is about 75cm high and 3.5m long. What is the best way to do this without damaging the brick wall?

What do you mean by "damage"? If you are excluding using wall plugs to fix uprights on one side, I suppose you could fabricate a structure that supports a vertical batten on each side that then holds the fence upright

Resin fixing will avoid expansion force

Or Multi Monties/Montys.

I meant something like drilling vertically through the wall to install an upright in the middle of the wall - I'd be worried that that might pull the wall down in a gale.

My thought had been to do exactly what you suggest, attach wooden uprights to my side of the wall.

[Timothy Murphy]

I'm afraid I didn't follow this. What exactly is "resin fixing", and what would I be fixing?

[Timothy Murphy]

Sorry, what are these?

[The Medway Handyman]

fixings. Drill through timber into brick, no plug, no expansion, drive straight in with drill driver. Easier to pull a sailor off your sister than pull one out.

I think we are assuming you will be fixing timber uprights to your side of the wall?

OTT for your job IMO. Steve was saying though, that normal plugs, which expand, can cause bricks to crack, especially near edges.

[Timothy Murphy]

Thanks for both your explanations. These look useful; I'd never heard of them.

Multi Monti's are brilliant, plus you can put them quite close to the edge of brick or stonework. You must use exactly the right size masonry drill though; it's easy to drill too large and then you have no grip.

But if you are asking whether the fence could pull the wall down in a wind, you need to say if it is single or double brick, whether there are piers, how high the fence needs to be, how exposed is the site, and how "open" is the lattice.

If you are trying to mount (say) 500 mm on top of a double brick wall you might get away with bits of rebar set into vertical holes. If you are after

2 m high lattice on a single skin wall you'd better mount it off (say) 75 mm square posts set into the ground (metposts?)

It's a strong double brick wall with piers. I think I'd like the lattice to be about 1m high (above the wall). I think I'll attach 4in posts to my side of the wall to hold the lattice.
