Laying slabs on a concrete base

[68-1093879177]

Can slabs be layed directly onto a fresh (wet) concrete base? The concrete would be on a firm soil base. What are the pros & cons. The slabs will form a path for light use and a mowing strip in a garden.

Yes, you can lay directly onto fresh concrete. best use a semi-dry mix, thougfh, as very wet concrete (greater than 25mm slump) allows flags to 'float' and shift in level when their neighbours are tapped down to level.

Pros - unlikely to move

Cons - expensive, unforgiving if you don't get it right first time, and limited working time.
