I'm planning to pave my backyard with bluestone. As you can see from the picture below, it doesn't look good at the moment. The ground is not level (I think because my house a bit higher that neighbours house) Just wondering what is the best way to tackle this? just topping up the sand and compact it and make it level is enough? or should I use mortar (1+5) for each paver? planning to put a BBQ there
For the best result you'd want to have a concrete base at least 75mm thick, then lay the pavers using mortar and finally add grout between them. Although it's a small area you'd also want to consider drainage.
Thanks for the vote of confidence @Jason. Sorry have been away.
@ehsantl Unfortunately, the photo doesn't really show much. You say that your ground level is higher than your neighbour. Does this mean that this area is retained in any way? If not, this could affect ground movement.
A good sand base is required with plenty of compaction. If you are worried about weeds and sand, then you could use a cement based grout once the stone has been laid.
As @Sporky has suggested, ensure the fall is away from the house. Rule of thumb is about 30-35mm of fall per metre, not per total width.
