The patio I have laid is 150mm below the DPC as required, fall 1:50. However I have a gap of around 75mm from the last slab to the wall. I am intending to fill the void with decorative gravel. Can I ask if I can just lay this on top of the DTP or should I fill the void with cement first? Any other recommendations? Thanks.
