An see,

If I recall this was all laid with 5" by 3" stick on its FLAT, so nominal 4"thick.

The scabby concrete in the foreground in the first photo was the first concrete laid in November with frost "proofer" added (and covered with a tarp and rugs/carpet) It was a 5.0m wide bay meant to be laid with a vibrating screed, which was hired but shited itsel, therefore concrete started to "go off" before it was fixed.

After getting burned with that experience the rest was laid the traditional way an levelled/tamped with a straight "stick" with blue water pipe handles (another cutting edge invention o mine, way back then)

Note this concrete ALL survived the 2010 bitter frost without spalling (well except for the shitty first batch)

Simply because no excess water added, therefore no pores cracks left when the excess water evaporates, therefore not porous therefore no free water contained within the concrete to freeze and burst.

The professional job done at my work, after this concrete was laid has since been replaced.

And it was reinforced and about twice as deep.

Gibber mutter an twitch.
