Just a side note for anyone thinking of following this guide: I'd recommend laying the larger crushed concrete first, and then adding the type 1 and compacting that. This way, you will have a flatter and more level surface to lay your slabs. You will also save on the amount of mortar you will need.
You might need a smaller trowel' the laser level is a good job, what happens if you need the path to fall over a distance, can the level be set for a run off?
Sigh. This looks difficult. Dont have clue about pave slabs and materials that come with it or even how to do it. Got grass uneven garden mud slide. If hire someone will cost a fortune. What a choice..
And yes , you haven’t a scooby doo in the construction industry, any natural stone requires a priming slurry whilst install Poor instructions It’s a no for me 😮
