Hi,
I had an Indian Sandstone patio laid at the start of the year but at the time the weather turned and frost / rain spoilt the pointing.
We have raked and cleaned out all of the pointing which was very sandy but noticed that about a third of the flags can be easily lifted from their mortar bed. They were laid on a full mortar bed with a wet mix.
The contractors doing the repointing feel the flags should be left alone as they are not rocking, just not adhered to the bed. They believe the new pointing and the fact that the bottom of the flags are heavily riven and shaped to the bed will hold them in place.
I feel that perhaps we should try to re-bed any loose flags now in case they move and spoil the pointing. In many cases you can hear the flags are loose when you walk on them.
What do others think?
Thanks very much.
