Block pavers on concrete

[23vc]

I’ve got a few areas of block paving to do, and some are fairly narrow sections which will have decorative aggregate either side, so I’ll make sure the outsides are well haunched.

How wide can you go and get away with just bedding them on concrete, like you’d do with the edges but do the whole lot on concrete? For example I don’t want a strip of screeded sand that’s too narrow for the whacker. I know bedding them on concrete isn’t the way to go, but for narrow strips say 18” wide, is it worth bothering with the sand bed in between the concreted edge courses?

Hope the question makes sense, not the easiest to explain. I’m basically asking how wide you’d go before you’d have to do it properly and have a sand bed, rather than just laying them all on a semi dry conc mix. TIA..

The problem with doing a section laid on concrete is when you tap them down the others will move, the best way is to lay your borders first, make sure the infill blocks will fit without cutting then haunch the outside and clean any mortar from inside section, next day lay the blocks inside using a semi dry mix and tap them to level, also fill with kiln dried sand.

I have done small paths like this in the past, for foot traffic it's fine

Spot on thanks,

Car will go over some of it as it’s a strip along the pavement boundary before it changes to gravel, but with good haunching and deep semi dry mix I reckon I can make it work

We never wacker pathways - too small an area - restraint an issues - vulnerable to dipping.

Rather, we mix up a s/c screed mix and bed them on that, and make sure that they are tapped into the (dryish) gear with a rubber hammer. Just leave overnight.

Thanks. When you say leave overnight assume you mean before walking on it, rather than before laying the pavers?

Correct. Let the muck go off
