Hi,

I think I've made a bit of an error on my patio height. As you can see from the pic the concrete base is 2 brick courses below the DPC and 1 below the aide brick - I was hoping to reuse some riven slabs but once bedded they'll come up to 1 and1/4 bricks below DPC and 1/4 brick below airbrick - will this be ok or should I look at thinner slabs/other suggestion.

Thanks

You need to leave 150mm between the ground and the dpc.

Can you dig out the concrete base, or install a Clark drain along the wall?
