Block paving help

[BertyFish]

I’ve dug up a raised flower bed and replaced with some block paving but stuck on the last part.

Order I’ve followed -

Dug down approx 150mm
Approx 50mm of hardcore and wacker
Level with some sharp sand wacker
Screed 20mm or close
Lay block paving

This is the bit I’m stuck on.
I threw some kiln sand down and passed over with the wacker but it knocked some of the bricks out line and edge ones out. I’ve managed to get them back in and aligned ok.

Should I have swept in all of the kiln sand in the gaps before wacker?
Plan is to put cement on the edging brick and slightly under to hold in place but didn’t want to do this before I wackerd as thought it wouldn’t let hit them down into the screed.

I’ve swept sand into all the joints now and covered as there’s some heavy rain due today.

You sweep in the Kiln sand last with a very soft brush.

The edge blocks are always secured in concrete, sounds like you are all loose laid?

[BertyFish]

Thanks, Im just worried cementing in the end blocks letting it dry then wacker the end block won t sink in?
It s quite a thin path but 20m long, couple of pictures to help explain.
Front row is concreted, ignore the first left was going to sort this after.

You have to concrete in the edge, then that retains everything, hence the rest can be loose laid.

Thanks, hopefully once I ve concreted the sides
they will still wack down a little even with the gaps filled with kiln sand.

The outer bricks need to be bedded and flaunched on a decent bed of concrete otherwise when you wack it you will have the same experience as before. Give them time to harden.

We had our patio “professionally” done and, at the installer’s suggestion, had it edged in blocks, concreted in. I watched it being done and I’d say it was all very belt and braces.

The grass has died where the concrete is and the blocks are slowly moving away from the patio. It strikes me that there ought to be a frame of some sort to hold them, or proper path edging, like the stuff that looks like strips of paving stone and can be sunk deep enough to hold in place.

I think my problem was watching the wrong YouTube video, Hopefully I can slightly dig under the end blocks to get concrete under as they are now as lifting them piles of kiln sand will poor out messing the screed height up.

Oh well learning curve, it’s only for walking on just annoying all the prep I did to make a mess up as the last hurdle.

You might be able to 'rescue' what you have completed with a plastic edging.

This isn't the one I was thinking of, but I can't remember what that one was called.

Sort of a nail down plastic wedge strip.
I haven't used it - it might not work for you.

Thanks, guess these might work.

Blocks are 80mm thick, this border is 60mm and stakes 180mm, worth a shot or pull up end bricks and watch the kiln sand go everywhere.

Luckily as all the blocks were sat on a good amount of sharp sand i was able to dig under the end blocks around 30mm in without taking them up,
plonked in plenty of cement then pushed this under with a joint trowel.
Let it dry for a bit then filled the edges up at an angle 40mm up, blocks are 80mm thick,

I dont think its going anywhere now but cant decide if to wacker on top now or just sweep on more kiln sand and rubber mallet any high sections.
