I have 80m2 of newish 100mm base concrete, which I would like to put 600 x 450 x 45mm precast concrete pavers on. What's the best material
for the bedding layer? I don't want to go up too high up against the house, because of the doorways as it will be used for wheelchair access. So as thin as poss really. I have about 15mm to 20mm

Hi Figment is the paving for a patio or driveway. If you only have 60mm to play with below the doors are you breaching your DPC.

Best bet may be to lay them on a plasticised full bed mortar mix with perhaps some Sbr or Pva added. If you're laying the flags on a very hot day then wet the bases as you go to aid adhesion. Is freeze- thaw an issue.
