Hi

I'm considering laying a limecrete patio slab. I'm considering it for
2 reasons:

1. I have neither a damp proof course nor damp proof membrane in my
house, and I'm concerned that a concrete slab next to it might cause
some damp.

2. Sometime in the future, I may be able to afford a little
conservatory on it, so I might as wall do the slab now while I'm
working on the patio anyway.

I'd rather not risk causing damp, but I'd also rather not risk the
slab not setting. I may end up putting a very small amount of cement
in the otherwise 6 ballast to 1 hydrated lime mix.

Any thoughts?
