Hi,

I am a total novice I layed some garden border edging blocks 3 weeks ago, I dug a 10" trench leveled it and tampered it down poured dry concrete in the trench leveled that, set the blocks in tapped them in and leveled them off (forgot to mention the blocks are 8"x 5"x 2") I then sprayed them with water. Problem is the blocks haven't stuck you can just lift them up the concrete base is fine and sound and fully cured but the blocks are loose how can I secure the blocks so they don't move? I have attached a few pics showing edging and how blocks lift up please give feedback thank you. I'm from the UK

Hi terry004
Lift your blocks off so you can put them back in the same orientation, mix up a slurry of neat cement, wet the blocks and your foundations and stick the blocks down by buttering the blocks.

that sounds like a good plan, could I use ready mixed mortar as I already have a bag of that...thanks for the help

Hi terry004
No you must use a neat cement slurry for it to be successful.

thanks I will give it a go
