The snow is eventually clearing and the forecast has suggestions of days
above 4C.

So I may be back in the concrete laying business after a forced layoff.

The ground, however, is going to be pretty soggy and there is a lot more
rain forecast.

My next step is to lay 100mm of MOT, whack it down, and put up the
shuttering.

The ground is fairly light (thankfully not clay).

So is there any reason not to crack on?

I can't see one immediately but thought I would check with the NG just in
case.

No.

I've not found whacking to be particularly good at compacting MOT mind
you, Consider rebar in the slab to prevent cracking.

If when you whack the MOT, you end up sitting in a pool of water, it is
probably too wet.

If it whacks down hard and doesn't do that, then the water is probably
helping, but allowing what's under the MOT to compact properly too.

Clay's probably the biggest pain - if it's sopping wet, it tends to slurrify
and push it's way into the hardcore (never used MOT, but regular rocky stuff
does this) and you never get the feeling that the hardcore is doing anything
but floating around on a wet layer of ****e, which will then shrink later
when it dries.

Got some frost protection ready for the concrete (additive or suitable
covering while it's going off)?
