Best fitting for Fixing Iron Gate to a cavity wall?

[Steve03]

Hi Guy's,

I have a cast iron gate which I would like to fit onto the side of the house.

I would be drilling into a breeze block cavity wall and was wondering what would be the best type of screw fitting to fix the heavy duty brackets securely as the gate is quite heavy. So I need a screw this copes with a lot of downwards pressure. I can't concrete a post in as it will narrow the side path too much and won't be able to get a wheelbarrow down it.

So my question is:

Do I use a expandable metal anchor screw or screwbolt?

Do I get a shorter length screw than standard breeze block depth?

Also will it benefit me if I add a small wooden batten rather than applying the brackets straight to the wall?

Cheers

It depends how close to the end of the building you are fixing to. If more than about 0.5m you can use expanding masonry anchors or the new masonry screws, but it would have to be exceedingly heavy to need more than 2.5" x 10 screws in brown plugs.
