Hi
I've never concreted before and I have a small job for the back garden.
I have a trench running along the side of the fence and I want to concrete about 2ft by 1ft which will house a metal, u-shaped bar; the purpose of which is to secure a chain locking up my bicycle.
I have some spare paving which I could use as the sides. Should I use bricks instead?
I'm thinking of laying hardcore on the base, which will be soil (as is the whole trench), I'm a little worried on how to make the concrete block secure, it'll be connected to one side of concrete which is the concrete floor leading up toward the trench, the other sides are soil and that's what's worrying me.
Can anyone give me some tips?
Your help is appreciated
Andy
