Block paving camber

[23vc]

Been a few days since I’ve asked a block paving question so here goes. My driveway is generally sloped in various directions due to house being lower than pavement, and also the street being on a hill. I have one area where it needs to ramp up a bit steeper, towards the edge.

I’m not sure whether to do this as a straight run using a string line, or just freehand more of a “parabolic” (?) dished/curved contour (see pic)

I think the straight would be easier when laying the edge course as I can run it to the line, but the curved is probably better/easier overall to manage when it comes to screeding and laying and compacting?

As ever, really appreciate any advice.

When ever I come off the screed rails, I like to get creative with the back side of my brickies trowel and try and sculpt the sand, when dealing with shapes and curves etc. It's better that the paving looks more naturally contoured than contrived and geometric.

Cheers. When you say “come off the screed rails” do you mean when you’re on a bit that you’re not screeding flat against the rails?

Makes sense what you say. I think this is something that becomes a bit clearer when you get stuck in and do it, and isn’t the easiest thing to picture when you haven’t done it before.

I’ll go with the curvey natural parabolic shape rather than a couple of straight planes.

Also, once you’ve done your freestyle brickies trowel thing, do you run the whacker over that part of the sand again? Or do you just get the blocks down and compact them? Thanks.

I like to compact the sand a little with the trowel, then tap the blocks with a rubber hammer, when dealing with specific areas. It means they behave a bit better when the compactor comes out.
