I recently bought a masonry BBQ which weighs 500kg and is 2m tall.
When I went to start building it, I noticed that my sandstone patio wasn't flat and that the base rocks with a maximum gap of just under half a centimetre.
The raised section of the patio is where there is a join in the slabs.
Is there a way to level this out without building another very thin base?
I thought there might be some relatively heavy-duty rubber mat I could put down, which would compress and level it off.
You will have gathered by now that I have no DIY experience.
Thanks
