Dear all
(I am new to your site and would like to start by saying that its great to find such a hands-on resource.)
As regards my topic, I was advised a number of years ago that slabs were best laid on a semi-dry, soft sand-sharp sand-cement mix, combining buttered edges with 5-spots direct over a Type 1 base. However, your advice does not seem to touch on this metod at all, might I ask why ?

With thanks, RR

Doesn't the site info refer to 5-pointing onto sand over a sub-base ? - thats certainly the impression given by the text/photo .....

the photo seems to show mortar over a sand bed
you seem to be trying to point-score here rather than debate ...

The 5 spot method does not conform to the relevant British Standards, as it leaves voids under the slab, leaking weak areas where the slab is likely to break.
